Abstract

The invention relates to the sewage treatment field, and specifically relates to a sewage treatment agent and an application thereof. The sewage treatment agent is prepared through the following steps: adding 10-20 parts by weight of aluminum into 20-30 parts by weight of fuming hydrochloric acid, stirring for 2-10 hours, then adding 100-1000 parts by weight of carbonate, and stirring for 12-36 hours; adding 100-200 parts by weight of polymeric chloride into 300-600 parts by weight of water, and fully stirring until being completely dissolved; mixing the substances obtained in the step 1 and the step 2, carrying out a stirring reaction for at least one hour, and thus obtaining the sewage treatment agent. The sewage treatment agent has concise composition, has simple preparation method, and cannot cause secondary pollution on water bodies due to introduction of a variety of elementary components; treated water bodies are transparent and pure, and conform to national A-level discharge requirements. The sewage treatment agent is particularly suitable for sewage treatment of leather, coking, medicines, electroplating, printing and dyeing, chemical industry, papermaking industries and domestic wastewater with complex pollutants and high degree of pollution.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment agent and its application. Background technique [0002] Conserving natural resources is an important part of wastewater treatment solutions. With the gradual development of industrial and urban functions, sewage treatment has been involved in all aspects of human life, and is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and other fields. Sewage treatment is an indispensable technology for people to protect the environment and love their beautiful homes. [0003] The flocculation process is a key link in sewage treatment, which is often achieved by adding flocculants, which are substances used to precipitate flocs from solutes, colloids, or suspended particles in aqueous solutions. Polyaluminum chloride is due to coagulation With high effect and low price...
