What are the general technical requirements and operating instructions of Inner Mongolia sewage treatment equipment structure? Today, I will take a look at the general technical requirements and operating instructions of the small sewage treatment equipment structure. I will take a look with you now. The overall technical requirements for the structure of small sewage treatment equipment: 1. Under the long-term low load conditions of the entire set of equipment: BOD5≤50ppm, SS≤100ppm, its effluent water quality should also fully meet the requirements. 2. The whole set of equipment has strong anti-shock load capacity. When the inlet water flow reaches a larger flow and the inlet water quality reaches the upper limit, the effluent water quality is still guaranteed. 3. The seller rationally designed the entire process system based on the biological treatment process based on the requirements of the quality and quantity of incoming and outgoing water. The process and equipment used by the seller are mature and reliable, proven by multiple engineering practices, and verified or approved by national or provincial authority. The whole process includes at least: primary sedimentation tank, biological treatment unit (including at least secondary), secondary sedimentation tank, disinfection tank, sludge tank, etc. 4. The sludge storage time is 300 days. 5. The entire system is convenient for operation and debugging. After the system is shut down, it can be put into operation directly without debugging. 6. All mechanical equipment such as fans (if any) of the integrated sewage treatment system are arranged in a unit for easy operation management, and electrical control equipment is arranged in nearby equipment rooms. The unit is designed with adequate ventilation facilities in accordance with relevant national regulations. The key is to kill the germs. Sewage treatment can adopt multi-stage filtration + membrane treatment + disinfection process. Sewage enters the sewage adjustment tank after passing through suspended grids, cotton, gauze, and feces. Installed at the front end of the wastewater treatment process to remove large suspended matter, marsh floats, fibrous matter and solid particulate matter in the wastewater , so as to ensure the normal operation of the subsequent processing structures, and the Inner Mongolia wastewater treatment reduces the processing load of the subsequent processing structures.

Small sewage treatment equipment operation instructions: Check before starting: 1. The system equipment is intact, there is no pollution blocking phenomenon in the grid well, and the lift pump outlet valve is opened. 2. Fan outlet valve and sludge riser air inlet manual valve are opened. 3. The float switch is good, and the high and low liquid levels are set appropriately. Ready status: 1. First close the main power air switch; 2. Close the main circuit power air switches of the pumps and fans; 3. Set the work system selection switch to the "manual" position; 4. Check each start and stop button The position is in the lifted state; 5. Close the control power switch and the secondary side control of the power transformer. Manual control: 1. To start the 1 # pump, press the 1 # pump start / stop button. At this time, the 1KM contactor is closed and the 1 # pump is started. 2. To stop the 1 # pump, press the button again. Press the start / stop button of # 1 pump to raise the 1KM contactor of Inner Mongolia wastewater treatment and stop the # 1 pump. 3. By analogy, the starting and stopping of 2 # pump, 1 # blower and 2 # blower can be completed in the same way. Automatic control: 1. Set the working system selection switch of the pump to the "Auto" position, and the pump will automatically control the liquid level according to the time sequence. 2. When the fan working system selection switch is set to the "auto" position, the fan is automatically controlled according to the timing liquid level. The equipment design is mainly aimed at producing sewage, and contacting the oxidation pond through mature treatment section and technology. Water quality design parameters are calculated based on sewage inlet BOD as mg / L and water BOD as mg / L. A total of seven parts of the sewage treatment process are composed of ⑴ hydrolytic acidification tank; contact oxidation tank I; ⑶ contact oxidation tank II; ⑷ precipitation tank; ⑸ fan room. The new wastewater recovery and treatment device replaces the traditional sink with membrane modules, which not only can completely remove suspended solids to improve water quality, but also can be separated by membranes to completely block free and macromolecular organic matter that cannot be trapped in the sink, especially those in the biological pond. Slow value-added. Unknown time Wastewater treatment chapter staff training During commissioning and operation, training is provided for enterprise sewage management and operators to reserve talents for the daily operation of sewage to ensure long-term stable operation of sewage.

(1) Grade A biochemical pool: In order to control the dissolved oxygen in the grade A biochemical pool to the left and right, gap aeration is used in the pool. This kind of filler has the advantages of not easy to block, light weight, large specific surface area, stable treatment effect, etc., and is easy to repair and replace, with a residence time of ≥ hours. (2) Grade O biochemical tank: A / O biochemical tank is filled with columnar bio-carrier fillers. The specific surface area of the filler is 16-20 times (the same unit volume) as that of general biological fillers. the goal of. The aeration equipment uses blowers and microporous aerators, and the utilization rate of oxygen is more than 30. Inner Mongolia wastewater treatment has effectively saved operating costs. (3) Sedimentation tank: After the sewage is treated by a Class O biochemical tank, the water contains a large amount of suspended solids (biofilms fall off), and a vertical flow sedimentation tank is used for solid-liquid separation. The sludge from the sedimentation tank is lifted to the sludge tank by air-lifting equipment. Inner Mongolia sewage treatment can also be based on the actual water quality and the sludge can be lifted to the A-level biochemical tank to return the sludge. Improve removal efficiency. (4) Disinfection tank: The contact time of the disinfection tank is 30 minutes. The disinfection uses chlorine dioxide. The treated water after biochemical and precipitation is disinfected. (5) Fan: The fan has low noise and long service life. In the system process, the fan is used for blast aeration and exchanged within 24 hours. When the water pump of the regulating tank is stopped, the fans will be aerated for 2 hours and the fans will be switched automatically every 24 hours. This process is controlled by the control cabinet. (6) Lifting pump: The lifting pump adopts anti-clogging and tearing type WQ submersible sewage pump, which has strong sludge drainage ability, no blocking, and can effectively pass solid particles with a diameter of 10mm. In summary, what Xiaobian brought to everyone about sharing the overall technical requirements and operating instructions of the structure of small sewage treatment equipment
