Description

Coagulant feeding device for wastewater treatment Technical Field The utility model relates to the technical field of wastewater treatment, in particular to a coagulant adding device for wastewater treatment. Background The coagulant adding device for wastewater treatment is equipment for adding coagulant into wastewater to realize wastewater purification treatment, and at present, the coagulant mainly uses liquid coagulant, and can be directly added, so that the operation flow can be simplified, the dissolution time can be shortened, and the device is more suitable for an automatic adding system; 1. At present, due to the change of conditions such as temperature, concentration and the like, crystallization or precipitation phenomena can occur in the storage tank, the solubility of the coagulant is reduced at low temperature, crystallization is easy to precipitate, the coagulant is adhered to the inner wall of the storage tank, the concentration and the components of the coagulant can be influenced by the existence of dirt, the performance of the coagulant is unstable, and the coagulant is inconvenient to clean manually at regular intervals, so that the labor intensity of operators is high; 2. After the coagulant in the storage tank stands for a long time, tiny particles in the coagulant solution gradually sink under the action of gravity to form precipitation, and as the reaction such as hydrolysis, polymerization and the like continuously goes on, reaction products are continuously accumulated, precipitation and layering phenomena can be aggravated, so that the concentration uniformity of the coagulant added by the coagulant adding device is inconsistent when the coagulant adding device is used, and the working quality is poor.
