Abstract

The invention discloses a sewage treatment agent and a preparation method thereof. The sewage treatment agent is prepared by mixing and reacting the following the raw materials of bentonite, quartz sand, peracetic acid, polyoxyethylene fatty acid ester, potassium alum, active carbon, silicon dioxide, calcium silicate, water-soluble cellulose and cross-linking agent. By adopting the sewage treatment agent, industrial sewage treated through the sewage treatment agent can be recycled, and the aims of saving energy and saving water are fulfilled. The preparation method is simple, is convenient to use, and is suitable for popularization and industrial production.

Description

technical field [0001] The invention belongs to the technical field of energy saving and water saving, and in particular relates to a sewage treatment agent and a preparation method thereof. Background technique [0002] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage produced in daily life, which refers to a complex mixture of various forms of inorganic and organic substances, including: ①floating and suspended solid particles of large and small sizes; ②glue Shape and gel-like diffuser; ③ pure solution. [0003] According to the nature of water pollution, there are two types of water pollution: one is natural pollution; the other is man-made pollution. At present, the most harmful to water bodies is man-made pollution. Water pollution can be divi...
