What are the forms of regulating tanks for sewage treatment equipment?

Classification of Conditioning Pools:

According to the form, the regulating pool can be divided into round, square, (natural) polygon, etc., and can be built underground or above ground. According to the structure, it is divided into concrete, reinforced concrete, stone structure and natural body. According to the position in the process flow, it is divided into a pre-original wastewater centralized regulating tank, and a plurality of diversion regulating pools and treated water regulating pools are set up according to the nature of the wastewater.

Generally, according to the function of the regulating pool, it is divided into water quantity regulating pool, water quality regulating pool and regulating tank with partial pretreatment at the same time.

Water volume adjustment, such as "variable water level pool + pump" method.

Water quality adjustment, such as "constant water level pool + stirring", adopts mechanical stirring or air stirring.

Water quality and quantity adjustment, such as the method of "variable water level pool + stirring + pump", and the method of "multi-point inlet variable water level pool + pump".

Accident water storage, such as setting up an accident tank next to it, stores high-concentration sewage discharged instantaneously, and then slowly adds it to the mainstream after the accident is resolved.

If the purpose of the regulating tank is only to regulate the amount of water, it is sufficient to maintain the necessary regulating basin volume and make the water output uniform. If the function of the regulating tank is to achieve a balanced water quality of wastewater, measures to achieve uniform water quality should be considered in the structure and function of the regulating tank, so that the wastewater flowing into the basin at different times can be completely mixed.

Common forms of conditioning pools are as follows.

Perforated diversion trough adjustment cell.

The outlet tank is arranged in the diagonal direction, and the wastewater enters the tank from the left and right sides, and flows out of the tank after different times, so that the wastewater without different concentrations can achieve the purpose of automatic adjustment and equalization. In order to prevent the water flow from short-circuiting in the pool, a sediment hopper can be set at the bottom of the pool to remove the sediment regularly. If the volume of the regulating tank is large, the regulating tank can be made into a flat bottom and the wastewater can be stirred with compressed air to prevent the sediment from settling down in the regulating tank.

The air consumption is, the effective water depth of the regulating tank is, and the longitudinal partition spacing is.

Segmented submersible water quality control tank.

The wastewater is bent in the partition wall, and the wastewater is distributed to various positions before and after the regulating tank through the multi-orifice of the distribution tank to achieve the purpose of mixing and balancing.

Air-stirred regulating tank.

Wastewater flows from the high-level aeration grit tank into the regulating tank, and the roommate aeration pipe in the pool plays the role of homogenization and pre-aeration, and the sediment in the tank is discharged with the water flow through aeration stirring.

There are also regulating pools that are composed of two or three empty pools, and the bottom of the pool is equipped with air pipes, and each pool operates independently intermittently and acts in turns. The pool is filled with water, the water flows into the second pool, and the water in the pool is stirred with air before being pumped to the subsequent equipment. *After the pool is emptied, the water from the second pool is pumped in order.

Although this can regulate the quantity and quality of water, the infrastructure and operating costs are high.

In order to make the pipes and structures work properly and not be affected by the peak flow or concentration of wastewater, the sewage treatment tank needs to be set up before the wastewater treatment is set up.

The regulating tank mainly plays the role of regulating the quantity and quality of water, as well as the adjustment of sewage pH value and water temperature, and can also be used as accident drainage.

For some reactions, such as anaerobic reaction, it is sensitive to water quality, water quantity and impact load, so for the regulating tank of appropriate size of industrial wastewater, the regulation of water quality and water quantity is the guarantee of the stable operation of anaerobic reaction. The function of the regulating tank is homogenization and homogenization, and it can generally be considered to have the functions of precipitation, mixing, dosing, neutralization and pre-acidification.

The role of the regulating tank in the sewage treatment project. The function of the regulating pool is to make the quality and quantity uniform. In general, functions such as precipitation, mixing, dosing, neutralization, and pre-acidification can also be considered.

Therefore, it is necessary to introduce the sewage with large fluctuation characteristics into the regulating tank for unified regulation, so that the water quality is relatively stable and provide stable and optimized operating conditions for the subsequent water treatment system. Specifically, the role of the regulating tank of sewage treatment engineering is mainly reflected in the following aspects: improving the buffering capacity of organic load and preventing rapid changes in system load; Reduce the fluctuation of sewage flow, stabilize the dosing speed used in sewage treatment, and adapt to the capacity of the drug delivery equipment; The neutralization capacity of different wastewater can be used to control the pH value of sewage, stabilize water quality, and reduce the consumption of neutralizing agents.

Prevent high concentrations of toxic substances from entering the biochemical treatment system directly; When the plant or other system temporarily stops discharging wastewater, the treatment system can continue to input sewage to ensure the normal operation of the system.

The above interpretation of the regulating tank is a structure used to regulate the flow of incoming and outgoing water. It mainly plays the role of regulating water quantity and water quality, as well as the adjustment of sewage pH value and water temperature, and can also be used as accident drainage. For some reactions, such as the anaerobic reaction, which is sensitive to water quality, water quantity and impact load, the regulation of water quality and water quantity is the guarantee for the stable operation of anaerobic reaction for the regulating tank of appropriate size of industrial wastewater.

The role of the regulating pool is homogenization and homogenization. You may have some understanding of it through the explanation of terms, but it is still very vague, and I didn't know anything about it before I was engaged in this industry, let alone know anything. After contact, I found that its role is still very large, it, it generally appears in the integrated sewage treatment equipment system in the fiber delay cover system, when it comes to the integrated sewage treatment equipment, many people may remember what it looks like, I don't know what it is called, and then we will talk about the regulating pool.

People who have experience in procurement may know that it is necessary to set up a homogeneous regulating tank in the integrated sewage treatment system, but what is the reason why it must be, it is not too clear, anyway, it is needed, hhh, and then let's talk about its principle and function.

The water quality, water quantity, pH or temperature and other indicators of wastewater discharged by general industrial enterprises often fluctuate greatly with the drainage time, and this change is very unfavorable to the operation of sewage treatment facilities, especially the normal purification function of biological treatment facilities, and even makes it completely destroyed. Therefore, for the integrated sewage treatment plant, because there is more than one kind of sewage discharged, and their water quality and quantity are constantly changing, it is very necessary to set up a homogeneous regulating tank.

The function of the homogenization regulating tank is to overcome the unevenness of sewage discharge, balance the changes in the water quality, quantity and water temperature of sewage, store surplus and supplement shortage, and make the inflow of biological treatment facilities uniform, so as to reduce the impact impact of sewage inconsistency on subsequent secondary biological treatment facilities. In addition, acidic and alkaline wastewater can be neutralized and treated with each other in the conditioning tank.

What is the purpose of setting up a homogenization conditioning cell?

1) Make the intermittent production plant continue to input wastewater to the biological treatment system when production is stopped, so as to maintain the continuous and stable operation of the biological treatment system;

2) improve the buffering capacity of the organic load and prevent the sharp change of the organic load in the biological treatment system;

3) Homogenize the incoming water to prevent high concentrations of toxic substances from entering the biological treatment system;

4) Control the large fluctuation of the closure value and reduce the consumption of acid or alkali in the neutralization process;

5) Avoid the fluctuation of the flow rate into the primary treatment device, so that the automatic operation of the process such as drug dosing can be carried out smoothly;

6) Homogenization tanks are installed in factories without biological treatment plants, which can control the discharge of wastewater to the municipal system.

Tips: The homogenization adjustment tank can be divided into the following homogenization pools; homogenization pools; homogenization cell; intermittent homogenization cell; Accident Conditioning Pool.

Yes, the municipal domestic sewage treatment plant generally needs to be equipped with a regulating tank.

A regulating tank is a facility used to regulate the flow and load of domestic sewage entering the treatment system. It has several main features:

1.Balanced inlet flow: The flow rate of urban domestic sewage varies greatly, especially in different time periods and holidays.

The regulating tank balances the flow into the treatment system, avoiding the impact of instantaneous large flow on the subsequent treatment process, so that the treatment system can better adapt to the changing load.

2.Storage and load regulation: The regulating tank can temporarily store the effluent entering the treatment system to regulate the quality and quantity of water. This slows down load fluctuations in the treatment process and improves the stability and effectiveness of the treatment system.

3.Balance Biological Clearance: The longer storage time in the conditioning tank can provide a longer biological contact time, which is conducive to the degradation of organic matter by microorganisms in the sewage. This plays an important role in the stability and improvement of the effect of the biological treatment process.

4.Dealing with sudden discharge: In the process of urban domestic sewage treatment, there are sometimes sudden sewage discharges, such as rainwater runoff during heavy rainfall. The regulating tank can receive these burst discharges and avoid overloading the treatment system and interruption of the treatment system.

The design and operating parameters of the regulating tank need to be planned according to the specific wastewater flow, changes in water quality, and the design requirements of the treatment plant. Through the setting of the regulating tank, the treatment efficiency and stability of urban domestic sewage treatment can be improved, and the effluent quality can be guaranteed to meet the discharge standards.

It is necessary to set up a regulating tank in the sewage treatment plant. The regulating cell can play a role in regulating the flow and homogenization, and plays a very important role in the subsequent treatment.

The regulating pool, also known as the accident pool. It has the following functions: 1. Preliminary settlement

Separate; 2. Adjust the water quality, so that the water quality can be balanced, which is conducive to the next process; 3. Adjust the amount of water. If the inlet water is not at a uniform rate, the pool can be adjusted; 4. It can realize the role of accident buffer. If there is a small failure in the subsequent treatment process, the wastewater can be stored here for a short time to play the role of buffer, so that the production process will not be shut down because the wastewater cannot be excluded, so it is also called the accident pool.

To put it simply: 1. Water quality adjustment, so that the regulating pool can have sufficient mixing time to collect all kinds of sewage to ensure that the water quality of the regulating pool is stable (if the pH of wastewater in some industries cannot meet the requirements of the subsequent process after mixing, then it is necessary to add an appropriate amount of chemicals to adjust); 2. Water volume adjustment, because each sewage treatment process will have a peak and trough period of water volume when storing wastewater, in order to ensure the continuous and stable flow operation of the process, the regulating tank also plays the role of water volume regulation.

Water quality regulation, so that the regulating tank can collect all kinds of sewage can have sufficient mixing time to ensure the stability of the water quality of the regulating tank;

Water volume regulation, because each sewage treatment process will have a peak and trough period of water volume storage, in order to ensure the continuous and stable flow operation of the process, the regulating tank also plays the role of water volume regulation.

These are the main two effects.

Regulate the water quality and water volume to prepare for the next treatment process.

Usually a sewage treatment system has a sedimentation tank, a regulating tank, a biochemical tank, a secondary sedimentation tank and a disinfection tank.

Pretreatment (sedimentation, grit tank), reaction tank (aerobic, anaerobic tank), secondary sedimentation tank (advanced treatment tank).

Answer]: c. Water distribution regulating tank and water quality regulating tank. The functions of the conditioning pool are generally as follows:

Provides the ability to slow the backflush of organic matter loads and prevent rapid changes in the load of biological treatment systems; pH control to reduce the amount of chemicals used in neutralization; Reduce the flow fluctuation of the physical and chemical treatment system, so that the chemical addition rate can be changed to fit the quota of the feeding equipment; When the plant is shut down, it can continue to feed wastewater into the biological treatment system; control the discharge of wastewater into municipal systems and mitigate changes in wastewater load; Prevent high concentrations of toxic and filial piety substances from entering the biological treatment system.

Answer] The purpose of setting up the regulating tank :d is to adjust the water quality and quantity of wastewater to make it balanced, but because the volume of the regulating tank is usually large, it is easy to cause sedimentation, so the regulating tank should have anti-sinking measures. The commonly used anti-settling method of the regulating tank is stirring celery, including air stirring, machine banquet machinery stirring and hydraulic stirring.
