Sewage treatment can use integrated sewage treatment equipment for treatment
Integrated sewage treatment equipment process
1. Sedimentation tank: check the water surface of the tank with or without floating debris, sludge floating phenomenon, to see if there is a clogged conduit.
2. Conditioning pool: see if there are large debris floating in the pool, try to clean up the visible suspended, floating debris to avoid clogging of the pump; check the operation of the pump, the pump is adjusted to the manual control, take out the float to test whether the switch is sensitive, the pump lifted out to check the suction mouth of the debris, test the pump circuit is normal, the valve opening and closing test, check the piping and valves for water leakage. 3. Air flotation pool: Observe whether the release of dissolved air water is normal, normal for the fine bubbles, the liquid surface can not have the phenomenon of flopping, to determine whether the dissolved air release device is off or clogging phenomenon. Observe the water color and suspended solids content to determine whether the flocculant dosage is appropriate. Observe the scum scraping and discharging situation, and check and test the scum scraper. Check the mud accumulation at the bottom of the equipment, open the air release valve to drain the mud, check the operation of the pump, test whether the pump circuit is normal, open and close the water outlet valve test, check the pipeline and the valve for leakage. Check the amount of debris in the dirt filter. Observe the water level and pressure in the dissolved air tank through the observation hole, and check the sensitivity of the liquid level meter. Check the oil level of the air compressor and the use of the filter element. ?
4. aerobic pool, contact oxidation pool, hydrolysis pool, anaerobic pool, parthenogenetic pool: check the water surface of the pool for floating debris. View filler hanging film. Check the amount of aeration and aeration strength. Check the operation of the pump, the pump is adjusted to manual control, the pump is lifted out to check the suction port with or without debris, test the pump circuit is normal.
5. Membrane pool: check the water surface of the pool with or without floating debris; view and analyze the properties of activated sludge; check the amount of aeration and aeration strength. Check the operation of the pump, the pump is adjusted to manual control, the pump lifted out to check the suction port with or without debris, test the pump circuit is normal. Analyze whether the membrane filament is off or clogged through the water discharge. Water flushing and chemical cleaning operations on the membrane. 6. Equipment room: check whether there is water in the equipment room. Check whether the control cabinet is energized normally, and test the components and lines in the cabinet; check the operation of the blower, whether the oil level is up to standard, whether the belt is damaged or not, and whether the filter core is adsorbed with too much debris. Test the opening and closing of the air outlet valve, and check whether there is any air leakage in the pipeline and valve. Check the operation of pipeline pumps, self-priming pumps, inlet and outlet valve opening and closing test, check the pipeline and valve leakage phenomenon. Check whether there is impurity deposition in the storage barrel of dosing device and membrane drug washing device, whether the operation of metering pump is normal, and check whether there is any leakage of pipes and valves. Pressure gauge, flow meter line and signal test. The company's products and services will be available for sale in the near future.
7. Other: gas extraction device operation test and solenoid valve line test. Water pump chain, exposed pipes for corrosion. Maintenance of environmental conditions around the sewage station, do a good job of related cleaning work, to avoid garbage piling, etc..
