Ground mounted oil separation and strong drainage equipment

Ground mounted oil separation and strong drainage equipmentWhen the inflow water quality fluctuates greatly or the pollutant concentration is high, this process can maintain normal operation, so the operation and management are also very simple, compared with the process.

1. In the wind system process, a fan is used for air blowing and aeration, which can be exchanged and used within 24 hours. When the regulating pool water pump stops, the fan aerates for 0.5 hours every 2 hours, and automatically switches once every 24 hours of fan operation. This process is controlled by the control cabinet.
2. Adopting jet aeration technology, no fan is required, which saves energy and reduces noise.
3. Install dosing devices, disinfection devices, and all connected pipelines according to the process requirements and actual situation.
When selecting sewage treatment equipment for sewage treatment plants, try to use some equipment that is easy to operate and maintain, which should be consistent with the current situation in China. If conditions permit, some automated equipment can be purchased. Wastewater treatment itself also has an impact on water, so wastewater treatment plants also need to pay attention to the stability of the treated water.
5. The staff should touch the filling material with their hands to see if it has a sticky feeling, and observe the growth of microorganisms in the water until a layer of orange yellow biofilm grows on the filling material. Only then can the sewage be continuously transported to the equipment, and the water volume should gradually increase to the design water volume;
6. If the electric pump is not used for a long time, it should be removed from the water and not soaked in water to reduce the chance of moisture in the motor stator winding and increase the service life of the electric pump.
7. Connect the control line of the electrical control box to the aerator and water pump, and connect the electrical control box to the power supply. When wiring, pay attention to the direction of rotation of the motor and fan, which must be the same as the indicated direction.
8. Adopting an automatic control system, aeration and operation can be timed, making the operation extremely flexible and saving 40% of electricity.
9. Automatic constant temperature control, stable reaction, controlled temperature of 40-75 ℃, yield of over 85%.
10. Equipment installation: All control boxes and junction boxes are fixed on the installed foundation steel with galvanized bolts. Welding is strictly prohibited to avoid damage to sensitive electronic components such as computers inside.
11. No need to compress the container. Equipment such as air compressors and circulation pumps greatly reduce investment costs.

After the filter material is laid, a backwash test must be conducted to check the backwash effect through ventilation and water flow
When there is no groundwater, compact and sand the foundation, and carry out foundation treatment according to the schematic diagram and requirements.
3. The sealing of gaps between filter plates and between filter plates and tank walls meets the design requirements.
4. The pH value must be ensured to be between 6.5-8.5, and the original sewage must be in a biodegradable state;
5. Raw water concentration: BOD5: standard type ≤ 250mg/L, reinforced type ≤ 400mg/L. If it exceeds 400mg/L, it needs to be designed separately.
6. There are a wide range of industrial raw materials and various types of products, resulting in significant differences in the amount and quality of wastewater discharged.
7. Fundamentally, it is necessary to reform production processes and eliminate the generation of toxic and harmful wastewater as much as possible during the production process. Replace toxic materials or products with non-toxic materials or products.
8. Connect the control line of the electrical control cabinet to the equipment, and pay attention to the direction of the underwater aerator and submersible pump motor when wiring. For example, the basement control cabinet should be placed in a ventilated area and kept dry. Generally, the control cabinet should not be placed outdoors. Be protected from sun exposure, rain, etc. To prevent electric leakage and burning of the control board and wiring terminals.
9. Some toxic wastewater that can be biodegraded, such as phenol and cyanide containing wastewater, can be discharged into urban sewers according to allowable discharge standards after being treated in the factory, and further subjected to biological oxidation degradation treatment by the sewage treatment plant.
10. The control system adopts a microcomputer controller with digital control and touch panel. The operating part has the characteristics of anti-corrosion, durability, and strong reliability.
