[0023] Working principle: The wastewater lifting system is equipped with a submersible sewage pump, which is placed in the raw water pool and equipped with high and low liquid level control. The electrical control conveys wastewater at high liquid level and stops conveying at low liquid level. At the same time, a float flowmeter and a valve switch are set on the conveying pipeline to control the conveying volume and conveying speed of sewage. The sewage enters a stirring zone of Fenton reaction and an acid stirring zone through the lifting system. The function of the acid stirring zone is mainly to adjust the pH value of the sewage. A pH meter is set in the acid stirring zone to control the acid dosing module in the dosing system, automatically start and stop the acid adding mode, and the sewage after the Fenton reaction enters the mixing zone. In the coagulation and sedimentation system, the first stirring zone of coagulation and sedimentation is the alkali stirring zone. The alkali stirring zone adjusts the pH value of the wastewater after the Fenton reaction. A pH meter is set in the alkali stirring zone to adjust the alkali dosing module in the dosing system. The wastewater after dosing and stirring evenly enters the inclined tube sedimentation tank through the lower water supply pipe, flocculates and precipitates, and the sludge sinks into the sludge bucket. The supernatant after coagulation and sedimentation enters the pH adjustment tank to adjust the pH value to between 6 and 9. Another metering pump for alkali dosing in the dosing system adds alkali to the pH adjustment tank. A pH meter is set in the pH adjustment tank to adjust the amount of alkali. The clear liquid with adjusted pH value enters the clear water tank, and the water in the clear water tank is lifted to the quartz sand filter and activated carbon filter by the lifting pump for filtration. The filtered clear water meets the discharge standards. The muddy sewage in the mud bucket of coagulation and sedimentation in the coagulation and sedimentation system enters the sludge thickening tank through the sludge lifting pump for concentration. The concentrated sludge is pumped into the screw stacker by the sludge screw pump for mud and water separation, and the mud cake is transported for external treatment.
