What do I know about the best solution for wastewater treatment? No matter what?

My sewage ** rate is 95%, I will not only do sewage but also exhaust gas and dust, and also do ventilation.

It's crazy! "I know the best solution for sewage treatment", hehe! Someone has to accept it!

What about your costs? Even if your ** rate is 100%, the cost is high, who wants it! Now it's a matter of cost for wastewater treatment!

Solution, hehe! That's a lot!

1. There are 4 kinds of sewage treatment methods. They are:

2. Precipitation (gravity separation). Due to the decrease in the flow rate of the sewage into the tank, the solid matter in the sewage is precipitated under the action of neutrality, and the solid matter is separated from the water. This process has good separation effect, is simple and easy, and has a wide range of applications, such as grit and sedimentation tanks in sewage treatment plants.

The grit tank is mainly used to remove the dense solid particles in the sewage, and the sedimentation tank is mainly used to remove a large number of granular suspended solids in the sewage.

3. Screening (interception). The sieve media is used to intercept the suspended solids in the sewage. The equipment that belongs to sand filtration treatment includes grid, microfilter, sand filter, vacuum filter, filter press (the latter two are mainly used for sludge dewatering) and so on.

4. Air flotation (floating). For some fine particles with a relative density close to water, it is difficult to sink or float in the water because of their own weight, and air flotation devices can be used. In this method, the air is injected into the sewage and precipitated from the water in the form of tiny bubbles, and the tiny granular pollution impurities (such as emulsified oil) in the sewage with a density close to the water adhere to the bubbles, and are removed as the bubbles rise to the water surface to form foam scums.

According to the different ways of air injection, air flotation equipment includes pressurized dissolved vapor air flotation, impeller air flotation and jet air flotation. In order to improve the air flotation effect, it is sometimes necessary to add a coagulant to the wastewater.

5. Centrifugal and swirl separation. The sewage containing suspended solids or emulsified oil, because the quality of suspended solids and wastewater is different, the centrifugal force is also different, and the suspended solids with large mass are thrown to the outside of the sewage, so that the suspended solids and sewage can be discharged out of the equipment through their respective discharge outlets respectively, so that the sewage can be purified.

Biological Sewage Treatment Act.

The use of microorganisms to degrade the organic matter in the sewage into harmless substances, common technologies include activated sludge method, biofilm method, AO process method, etc.

Physical sewage treatment method.

Physical sewage treatment methods are commonly used in sedimentation method, filtration method, air flotation method, centrifugal separation and magnetic separation.

Chemical method. The commonly used methods of chemical methods include coagulation and precipitation, neutralization, redox and chemical precipitation.

Normally, the domestic sewage of the city is divided into two categories, the first is industrial sewage, and the second type is domestic sewage, which will be collected to a designated place through the urban pipeline and treated centrally, so that the sewage can meet the designated standards in China.

Biological treatment method: This method is to use microorganisms to treat sewage, so that the organic matter in the sewage is purified into a harmless and stable domestic sewage treatment method. At the same time, it can be divided into two types according to different organisms: anaerobic and aerobic, among which sewage treatment is widely used to solve the problem, and according to the tradition, it can also be divided into two types: biofilm method and activated sludge method.

Chemical treatment: This is a way to solve the problem of sewage by using the form of chemical reaction, through separation, dissolution, colloidal and other means to purify the organic matter in the sewage into harmless and stable substances. We need to invest in agents to facilitate the transformation, where the reaction basis is:

Neutralization, coagulation, reduction, etc.

Physical treatment method: This is a way to use physical properties to solve the problem of sewage, through the means of separation, separation, etc., which can be divided into centrifugal separation method, center of gravity separation method, filtration and other methods.

Biological Contact Oxidation: This method is more difficult to explain, and simply uses a biological contact oxidation process and provides a filler that incorporates oxygenated wastewater into the filler and flows through the filler at a specific flow rate.

The above domestic sewage treatment methods are also more commonly used, and they can be selected according to the actual needs, and do not pursue Qi Daquan.

Physical method: It mainly uses physical action to separate the insoluble substances in the sewage, and does not change the chemical properties during the treatment process. Biological Law:

The metabolic function of microorganisms is used to decompose and oxidize the organic matter in the dissolved or colloidal state in the sewage into stable inorganic substances, so that the sewage can be purified. Chemical method: It is a method that uses chemical reaction to treat or dissolved substances or colloidal substances in sewage, and is mostly used in industrial wastewater.

1. Physical method: It mainly uses physical action to separate non-soluble substances in sewage, and does not change the chemical properties during the treatment process. Commonly used are gravity separation, centrifugal separation, reverse osmosis, air flotation, etc.

2. Biological method: using the metabolic function of microorganisms, the organic matter in the dissolved or colloidal state in the sewage is decomposed and oxidized into stable inorganic substances, so that the sewage can be purified. Commonly used are activated sludge method and biofilm method.

3. Chemical method: It is a method that uses chemical reaction to treat or dissolved substances or colloidal substances in sewage, and is mostly used in industrial wastewater. Commonly used are coagulation method, neutralization method, redox method, ion exchange method, etc.

If you are going to do sewage treatment covering projects, I can tell you that there are three types of projects:

1 ordinary carbon steel skeleton sunshine board.

2 stainless steel skeleton FRP plate.

3. Ordinary carbon steel (anti-lifting) membrane (fluorocarbon fiber membrane).

The steel supporting part of the two structural forms is inevitably placed inside the top cover, because the concentration of corrosive gas inside the pool top is doubled after the cover is added, the temperature is very high under the sunlight radiation, and the steel structure inside is very easy to corrode, and the general life is 3 5 years, that is, in a short period of time, it is faced with the secondary construction of the whole structure. Even if the steel structure is made of stainless steel, durability in corrosive environments is not guaranteed and the cost is very high.

The third membrane system successfully solves this problem and makes full use of the advantages of the material itself.

The steel support reverse hanging fluorocarbon fiber membrane structure is a new type of structure specially developed for the capping of the sewage pool, which selects the corrosion-resistant fluorocarbon fiber membrane as the covering material, and adapts to the corrosive environment of the sewage pool through the form of reverse lifting.

If you want to do sewage capping projects, you can ask Wuhan Mittal Building Membrane Engineering ****, they are professional companies specializing in sewage treatment covering projects! It is well-known in the industry. Hope I can help you!

Sewage treatment can be divided into three types: physical, biological and chemical.

Physical method: Changtong is mainly used to physically separate the non-soluble substances in the sewage, and the chemical properties are not changed in the treatment process. Commonly used gravity separation, centrifugal separation, reverse osmosis, floating, etc.

The physical treatment structure is relatively simple, and it is used for the situation that the water body of the village and town has a large capacity, strong self-purification ability, and does not require a high degree of sewage treatment.

Biological method: Using the metabolic function of microorganisms, the organic matter in the dissolved or colloidal state in the sewage is decomposed and oxidized into stable organic substances, so that the sewage can be purified. Commonly used activated sludge method and biofilm method. The biological method is more highly processed than the physical method.

Chemical method: It is a method that uses chemical reactions to treat or treat dissolved substances or colloidal substances in sewage, and is mostly used in industrial wastewater. Commonly used coagulation method, neutralization method, redox method, ion exchange method, etc.

Chemical treatment method, high, mostly used as biochemical treatment of effluent, for further treatment, to improve effluent quality.

Classification of sewage treatment products

Commonly used products for sewage treatment are: quartz sand filter material, anthracite filter material, polyaluminum chloride, activated carbon, honeycomb inclined pipe filler, fiber ball filter material, garnet sand, etc.

Polyacrylamide products are simple and high-medium: polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents, with good flocculation, can reduce the friction resistance between liquids, according to ionic characteristics can be divided into four types: non-ionic, anionic, cationic and amphoteric type.
