Mixing pool charging mechanism for treating wastewater

Abstract

The invention discloses a mixing pool charging mechanism for treating wastewater and relates to the technical field of wastewater purification. The mixing pool charging mechanism comprises a feeding tank and a mixing tool, wherein a stirring device is further arranged between the feeding tank and the mixing tool; a cavity in the stirring device is divided into a stirring cavity, a filtering cavity and an input water filtering cavity; the filtering cavity is provided with filter net cloth; a water inlet is formed in the input water filtering cavity; the input water filtering cavity is internally provided with input water filter cloth; the mixing pool and the stirring device are communicated through a medicine outlet pipe; one end of the medicine outlet pipe is arranged in the filtering cavity through a medicine outlet and the other end of the medicine outlet pipe extends back and forth between a water inlet end and a water outlet end of the mixing pool in a snake shape; a plurality of medicine outlet holes are formed in the medicine outlet pipe. The mixing pool charging mechanism disclosed by the invention has the advantages that medicines are uniformly mixed, purification load of following procedures is reduced, the purification efficiency is improved and semi-purified water can be used as water for diluting the medicines.

Description

technical field [0001] The invention relates to the technical field of wastewater purification, in particular to a mixing tank feeding mechanism for wastewater treatment. Background technique [0002] A large amount of wastewater is generated in industrial production processes such as papermaking, and such wastewater is usually treated by a supporting wastewater treatment system. The wastewater treatment system in the prior art includes water purification reaction pools such as regulating pools, AO pools, mixing pools, and sedimentation pools. By adding corresponding chemical coagulation and flocculants in different pools, the solid-liquid separation of wastewater can be realized, and the technical effect of purifying wastewater can be achieved. [0003] The mixing tank is used to mix chemical purifiers such as polyaluminum chloride with sewage, and then electrochemical, coagulation, adsorption, precipitation, etc. occur in sewage to achieve the purpose of purification.

Problems solved by technology

However, in the actual treatment of wastewater in a large mixing tank, it was found that due to the limitation of the stirring range of the stirring paddle and the factors of water flow, the liquid medicine fed by one or several lifting pumps has only It is difficult to fully mix with wastewater at one or several delivery points, resulting in a low actual usage rate of the liquid medicine
