What items should be checked before using industrial sewage treatment equipment?

Before using the industrial sewage treatment equipment, check whether the circuit and wiring control cabinet circuit are correct, whether the current and voltage meet the requirements, and check whether the water pump pipeline has leakage, water absorption and blockage. In addition, the design of the equipment should also strictly implement the current environmental protection technical standards and specifications. Next, let's introduce the relevant contents in detail.

1、 Inspection of industrial sewage treatment equipment before use

1. When starting the equipment, check the circuit, whether the wiring control cabinet circuit is correct, and whether the voltage and current meet the requirements. The equipment is controlled by microcomputer, controlled by programmable controller, and the output adopts AC contactor. Refer to the manual of microcomputer automatic control cabinet for specific instructions. The control cabinet can control two submersible sewage pumps and two fans at the same time and monitor them in combination with the working conditions. It has the function of automatic protection and alarm, and is also equipped with manual and automatic control systems. When starting the water pump, check whether the water pump pipeline has leakage, water absorption and blockage.

2. The water pump of the equipment adopts anti blocking and tearing submersible sewage pump. The control of two water pumps is completed by microcomputer by detecting the liquid level in the sewage tank. When the liquid level reaches the working water level from low to high, start the working pump. If the liquid level continues to rise to the warning water level, turn off the working pump and check whether the rotation direction is correct when starting the fan. Do not reverse it.

3. When there is less sewage in the regulating tank and the liquid level is lower than the starting liquid level of the water pump, both water pumps stop working. At this time, in order to make the biofilm in the sewage equipment grow normally, the fan starts intermittently, starts for 10 minutes and stops automatic operation for half an hour.

4. Sludge discharge control in sedimentation area: solenoid valve is used for stripping sludge or sludge pump is used for lifting sludge discharge. The sludge discharge cycle is 8 hours and the sludge discharge time is 8 minutes. When stripping, two fans are started at the same time to ensure the supply of gas.

5. The fan and water pump adopt automatic alternating operation control, and the alternating switching time is 4 hours.

6. The equipment control center completes the manual control at one time on the microcomputer cabinet according to the engineering program arranged in the design. The submersible sewage pump and fan are manually controlled to start and close through the key switch on the panel.

2、 Design principles of industrial sewage treatment equipment

1. Strictly implement the current environmental protection technical standards and specifications, and abide by the relevant laws, regulations and emission standards of local environmental protection.

2. The advanced, reasonable and reliable treatment process shall be selected to achieve simple operation, convenient management, small land occupation, low investment and low operation cost on the premise of ensuring that the treatment discharge meets the standard.

3. The project is an environmental project, and special attention should be paid to environmental protection to avoid and reduce secondary pollution. It is required to improve labor hygiene conditions and implement the policy of production and clean and civilized production.

4. In order to improve the management level of sewage treatment station, full-automatic program control is designed to reduce the labor intensity of operators.

5. Reasonably select accessories, reduce energy consumption, improve work efficiency and service life, and reduce system operation cost.

6. In the process design, it has greater flexibility and adjustability to adapt to the periodic changes of water quantity and quality. A set of (integrated buried) sewage treatment facilities is adopted to improve the flexibility, variability, adaptability and advanced nature of the system. Considering the accident emergency discharge measures of the system.

7. Sludge pre reflux nitrolysis process is adopted to reduce sludge production.

8. Adjust measures to local conditions, make rational layout and make effective use of space and site.
