Abstract

The invention relates to a sewage treatment agent. The sewage treatment agent is composed of, by mass, 20-40 parts of polyamino polyether methylene phosphonate, 20-40 parts of diazolidinyl urea, 10-30 parts of methylisothiazolinone, 15-30 parts of medical stone particles, 40-60 parts of sodium lignin sulfonate, 20-40 parts of chitosan, 20-40 parts of polyvinylpyrrolidone, 20-40 parts of polysilicate aluminium sulphate, 20-40 parts of diacetone acrylamide, 20-40 parts of phosphonate and 50-100 parts of deionized water. According to the sewage treatment agent, the reaction speed is high, poisonous and pernicious gas is not produced in the treatment process, products are stable after reactions, and the products do not break down into toxic substances; by means of the sewage treatment agent, efficient and non-poisonous effects are achieved, corrosion to human bodies and objects does not occur after and before the reactions, and the treatment efficiency to sewage is high.

Description

technical field [0001] The invention relates to a sewage treatment agent, which belongs to the technical field of sewage treatment. Background technique [0002] At present, environmental protection has become a concern of the world, and the discharge of industrial sewage has strict requirements.
