<> about the installation and construction process of sewage treatment engineering equipment? If you want to know the answer, the following is the relevant content of the installation and construction process of sewage treatment engineering equipment sorted out by Zhongda Consulting Travel, and the basic situation is as follows:

With the rapid development of the economy, the treatment of urban sewage has become more and more important. The quality of the installation and operation of sewage treatment equipment also directly determines the effect and efficiency of water treatment. In today's modernization, the installation and application of sewage treatment equipment have also increased significantly.

In the urban sewage and industrial wastewater treatment system, there are usually aerators, mechanical grids, filter presses, aeration blowers, pumps, sludge scrapers, suction dredges, conveyors, submersible mixers and other equipment, and are equipped with flowmeters, detectors and other laboratory equipment, through the pretreatment, biochemical treatment and physicochemical treatment of sewage, etc., to achieve the purpose of removing pollutants in the water.

Sewage treatment engineering equipment installation and construction technology:

1. Unpacking inspection and treatment of the town spike.

2. Foundation acceptance and processing, when the foundation is handed over, there should be a quality certificate and measurement records, and the elevation reference line and the vertical and horizontal center line of the foundation should be clearly drawn on the basis, and the foundation of important equipment should have settlement observation points; According to the shape, size, weight and distance of the equipment, different transportation and hoisting methods are selected.

3. The equipment is in place and aligned and leveled.

What information is required for the installation and commissioning of sewage treatment plant equipment and audit?

1. Acceptance beam application report; 2. Monitoring station monitoring report; 3. Environmental impact assessment of sewage treatment plant, sewage design plan, design drawings and other materials; 4. Introduction to the pollution sources of the enterprise and the treatment measures of various pollution sources (collating a piece of information, wastewater is discharged quickly if it is disposed of, how to treat waste gas, what method is used to treat noise, and how to collect and treat solid waste).

The preparation before the commissioning of the integrated sewage treatment equipment is still very important, if it is not done well, it will affect the commissioning cycle and effect.

General engineering companies, construction units and equipment installation units need to conduct self-inspection on civil conditions, equipment, hydropower and other projects to ensure that the project meets the commissioning conditions, and the specific requirements are as follows:

1. Civil engineering conditions: civil engineering construction such as (grid canal, regulating tank, sludge tank, equipment foundation, etc.) to complete the commissioning team to prepare the commissioning outline, stand-alone commissioning linkage test run microbial culture trial operation and through a single experience collection, to meet the relevant requirements of the integrated domestic sewage treatment equipment when it is running.

5. Water and electricity: the sewage pipe network has been connected to the sewage treatment (station), and the power supply of the equipment has been connected to the equipment and meets the requirements of use;

Before the commissioning of the integrated sewage treatment equipment, it is generally necessary to do civil engineering, equipment installation, electrical installation, and pipeline installation! However, after the judgment of Huai, the water and electricity are connected! These are all debugged, and only when you dig up dry friends can you do the equipment debugging work before sewage treatment.

Before the commissioning of the integrated sewage treatment equipment, it is necessary to do the quasi-failure oak dismantling and preparation work, such as the car: check whether there is electricity, whether the equipment is installed, whether there is enough sewage for commissioning and use, etc.

1. The results of the small test do not mean that Kai Ji is correct in actual use, and the dosage needs to be fine-tuned on the basis of the small test, because the water quality of the inlet water is generally uneven.

2. The quantity and quality of the material must not exceed the design standards, otherwise there will be problems.

The preparation work before the commissioning of the live integrated sewage treatment equipment is still very important, if the stove is not done well, it will affect the commissioning cycle and effect. General engineering companies, construction units and equipment installation units need to conduct self-inspection on civil engineering conditions, equipment, hydropower and other projects to ensure that the project meets the conditions for commissioning.

In order to ensure the smooth progress of the work of the domestic sewage treatment equipment in Hetingliang, the time of Zen Yun is reduced. It is necessary to draw up a commissioning plan in advance, such as time and place, debugging content, etc. Arrange maintenance and management personnel and various materials and raw materials needed as soon as possible.

Civil engineering conditions: civil engineering construction quietly takes such as (grid canal, regulating tank, let's transport sludge tank, equipment foundation, etc.) to complete the preparation and adjustment of the vertical adjustment tanmin test group, equipment installation: The equipment supporting the integrated equipment mainly includes lifting pumps, liquid level gauges, blowers, and ultraviolet sterilizers.

Some preparations should be made before the commissioning of sewage treatment equipment, such as the preliminary work must be prepared, so that the later commissioning may be larger.

If we don't do this work, there may be some problems and problems, so we should pay attention to this situation.

Before the water quality commissioning of domestic sewage treatment equipment, many preparations must be completed, and if these preparations are not completed, the commissioning cycle and effect will be affected. Today, we will introduce you to the preparations before the commissioning of the sewage treatment equipment.

Hello, in order to ensure that the work of domestic sewage treatment equipment is carried out smoothly and reduce time. It is necessary to draw up a commissioning plan in advance, such as time and place, debugging content, etc. As soon as possible, the maintenance management personnel of Anqing Youpai and the various materials and raw materials needed by Changmo, I hope to help you.

It is okay to do some simple sewage treatment. I can't dare to touch anything, the main thing is that the wider source shirt is loose, so I will engage a little professional person to do it, and what I heard before will be cracked and dealt with. Assault.

These preparations should be made before the commissioning of the integrated sewage treatment equipment: check the power supply, check whether the components are complete or not, and whether the installation is normal.

The integrated sewage treatment equipment checks whether the electrical lines are in a quasi-leakage working state and whether the wiring method is correct. If any abnormality is found, it should be corrected in time.

Life talks about this sewage treatment equipment, sewage treatment equipment, sewage treatment equipment, empty Song Xun gas dissolution value of 27%, widely used in the industry, green environmental protection, no secondary pollution,

1. Add sludge, which can be dewatered sludge or watery sludge, and calculate the dosage according to your pool capacity;

2. Stuffy exposure, add a certain amount of raw water or tap water, and expose it for 3-5 days;

3. Intermittent water intake, a certain amount of raw water is inlet every day, the bacteria that use the raw water are screened out, and nutrients are added, which takes about 10 days at this stage;

4. Gradient water intake, gradually increase the water inflow, until all the water is inflow, this stage of the spike balance section takes about 10-15 days.

Precautions: 1. DO, the dissolved oxygen can be controlled well, and the general activated sludge can be between the 2-4 early groups in contact oxidation;

2. pH, when the pH is low or high, you need to adjust the pH before entering the water. Generally acceptable at 6-9;

3. Temperature, the appropriate temperature should be between 15-35 degrees;

4. During the commissioning of the inlet load, the inlet load should be strictly controlled to avoid impact;

5. The amount of water should be well controlled;

6. There are some others, such as heavy metals, disinfectants, suspended solids, etc.

Commissioning is trial operation, including stand-alone test operation and linkage test run. Debugging is actually the process of linkage between equipment, automatic control and process. The main aspects are as follows:

1) Stand-alone operation: including the stand-alone operation of various equipment after installation and the test of each processing unit structure. In the case of influent water and influent water, the sewage treatment equipment is put into trial operation, and the water level of the hydraulic structure is checked to see if it meets the design requirements.

2) Carry out the clean water linkage trial operation of the design water volume of the entire process system to open up the process flow. Inspect the operation of the equipment under the flow of clean water, and check whether some automatic control instruments and pipelines and valves connecting each process unit meet the design requirements.

3) Each treatment unit at all levels of treatment enters the wastewater to be treated, and the treatment effect of each treatment unit is tested or preparations are carried out before formal operation (such as cultivating and domesticating activated sludge, etc.).

4) The whole process wastewater linkage trial operation until the effluent water quality reaches the standard. At the same time, the stability of the equipment operation is further checked, and the linkage of the automatic control system is realized.

According to the above aspects, it is gradually subdivided into each treatment structure (such as the main content of sedimentation tank commissioning: the operation of the scraper, leak detection, whether the main indicators of the inlet and outlet water are consistent with the design value, etc.), and finally the commissioning plan is formulated.

First, the purpose and content of the trial operation(2) Main content and procedures.

2) Stand-alone test requirements.

1) Stand-alone test run, generally empty test run for no less than 2 hours.

3) Online operation requirements.

4) The online operation of the whole plant should not be less than 24 hours.

6) Continuous trial operation.

1) The single unit of the treatment equipment and pump room has been in operation for a total of 72 hours.

2) During the continuous trial operation, the machine should be started and stopped no less than 3 times.

3) The joint trial operation time of the treatment equipment and the pump room unit is generally not less than 6 hours.

4) The trial operation of the water treatment and sludge treatment process system meets the process requirements.

5) Fill in the equipment load linkage (system) trial operation record form.
