Background
Phosphorus and ammonia nitrogen in domestic sewage are important substances causing water quality deterioration. The phosphorus content in the water body is closely related to the eutrophication degree of the water body, and ammonia nitrogen can be used as biological nutrient substances to induce eutrophication after entering the water body, so that the fishy smell of the water is bad, a large amount of dissolved oxygen is consumed, and toxins are discharged to the water body, thereby causing the disturbance of the aquatic ecosystem. Due to various hazards of phosphorus and nitrogen pollution and the improvement of water quality and water quantity requirements of people, the improvement of water quality of water sources by adopting corresponding technical means and measures of deoxidization and dephosphorization purification has been increasingly focused by society.
At present, the removal of ammonia nitrogen and phosphorus in domestic sewage mainly depends on a nitrifying denitrification method and a phosphorus removal type anaerobic and aerobic activated sludge method. The ammonia removal of the nitrogen-containing component is mainly that ammonia is oxidized by nitrate ions in an aerobic process, and oxidized nitrate is reduced into gaseous substances such as nitrogen and the like; in the phosphorus removal process, phosphorus is released from microorganisms in an anaerobic process, and the microorganisms absorb phosphorus in an aerobic process, and the microorganisms absorbed with phosphorus are removed as flocculates by precipitation, so that the removal effect of ammonia nitrogen and phosphorus in domestic sewage has a high correlation with the anaerobic, aerobic and flocculation processes. However, the components of the domestic sewage are not constant and stable, the content of nitrogen and phosphorus in the domestic sewage has larger fluctuation, and the removal rate of nitrogen and phosphorus in the traditional domestic sewage anaerobic and aerobic removal method has the relationship.
The electric flocculation can generate a unique flocculation environment in the domestic sewage treatment process, which is favorable for removing phosphorus sediment, but the electric flocculation external electric field is too weak to achieve the due flocculation effect, and the external electric field is strong to improve the flocculation sedimentation effect, but also inhibit or weaken the growth and proliferation of microorganisms, so that the microorganisms are poisoned. The content of phosphorus in domestic sewage is also changed, and the flocculation effect of the electric flocculation is matched with the content of phosphorus so as to achieve better phosphorus removal effect.
The inventor applies for 2021.11.12 for a closed-loop control treatment device for domestic sewage, and the patent application number is: 202122787240.9; according to the patent application, the oxygen supply in the aerobic cabinet and the electric field intensity in the electric flocculation cabinet are regulated and controlled through the detection of the turbidity of domestic sewage and the monitoring of transient water quality indexes such as the water outlet conductivity and the pH value, so that the sewage treatment effect is improved; however, the treatment device can not control the strength of the aerobic and flocculation effects according to the removal effect of nitrogen and phosphorus in the treated water, the aerobic and anaerobic effects can not realize timely regulation and control, and the anaerobic or aerobic working procedure has almost no flocculation precipitation effect and the dephosphorization effect is not ideal; meanwhile, the membrane bioreactor in the treatment device has the problem of membrane pollution which is difficult to solve.
