Background
Currently, in many sewage treatment occasions, the chemical treatment technology is usually used to improve the sewage treatment efficiency. Especially for the treatment of phosphorus-containing sewage in chemical industry, the auxiliary treatment is usually carried out by slag or lime. However, in the conventional phosphorus-containing sewage treatment technology, slag or lime is usually poured into a sewage pool by manual pouring or the like, and the auxiliary treatment substance reacts with phosphorus in sewage by chemicals to generate Ca5(OH)(PO4)3And precipitating the precipitate, and treating by settling or filtering to obtain domestic water or industrial water with relatively good water quality.
However, the inventor finds that in the actual calcium method phosphorus removal technology, if slag or lime is directly poured into sewage for reaction, the situation that the reaction between the treating agent and phosphorus-containing substances in the sewage is insufficient usually occurs, and the efficiency and the quality of sewage treatment are reduced. Subsequently, the inventors have found through field experiments that the above-mentioned insufficient reaction can be effectively solved by dispersing and scattering slag or lime into a wastewater tank during the treatment of phosphorus-containing wastewater. However, due to the lack of specialized equipment, the efficiency of each time sewage treatment chemicals or agents are spilled into the sewage tank is relatively low, and the labor is relatively high, which is not an ideal construction method.
