Abstract

The invention provides a cyclic utilization system and process of a phosphorus removal agent. The system comprises a settling device for settling sludge in sewage, a sludge thickening tank connected with the settling device, an acid pickling tank connected to a sludge discharge port of the sludge thickening tank, a reaction tank connected to a liquid phase outlet of the acid pickling tank, and a settling tank connected with the reaction tank, and a liquid outlet of the settling tank is connected with the settling device. According to the cyclic utilization system of the phosphorus removal agent, sludge is subjected to acid pickling, phosphorus in the sludge is washed out, then supernatant enters the reaction tank for phosphorus removal, water eutrophication is avoided, and after the reaction is completed, the supernatant is conveyed into the settling device to be mixed with sewage for cyclic phosphorus removal. Meanwhile, the reaction tank is provided with a cleaning device and a pressure stabilizing device, the interior of the tank can be cleaned, and meanwhile, stable air pressure in the tank body is ensured during reaction.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a recycling system for phosphorus removal agents. Background technique [0002] Phosphorus is an essential element for the growth of all organisms on the earth and plays an extremely important role in human life activities. However, phosphate rock is a non-renewable resource. With the acceleration of my country's population urbanization process, resulting in a dramatic increase in sewage. A large amount of phosphorus-containing domestic sewage increases the eutrophication of the water body, causing the abnormal reproduction of algae and aquatic plants in the water body. Therefore, in recent years, my country has made stricter regulations on the nitrogen and phosphorus indicators in urban sewage discharge. [0003] The existing methods for phosphorus removal from sewage mainly include: physical adsorption method, microbial method, hydrobiological method, and membrane te...
