Problems solved by technology

[0003] Discharge of domestic sewage without treatment will cause serious environmental pollution such as pathogen pollution, aerobic organic pollution, eutrophication pollution, stench, acid, alkali, salt pollution, increased groundwater hardness, and toxic pollutant pollution. Therefore, there is an urgent need for a High-efficiency sewage treatment agent can remove various pollutants in domestic sewage, so that the treated sewage can meet the discharge standard and avoid environmental pollution

Abstract

The invention relates to the field of sewage treatment, in particular to a domestic sewage treating agent. The domestic sewage treating agent is prepared from, by mass, 5-15 parts of aluminum chloride, 60-150 parts of kieselguhr, 20-60 parts of ferric sulfate, 5-15 parts of dithiocarbamate, 5-10 parts of chitosan, 3-8 parts of caustic soda flakes and 2-6 parts of a microbial biofilm. The domestic sewage treating agent is high in treating efficiency and good in treating effect, treated sewage can reach the emission standard, and environmental pollution can be avoided.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a domestic sewage treatment agent. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for drainage or reuse. 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, while domestic sewage is mainly various detergents and sewage, landfill leachate, and feces used in urban life, which contain a large amount of inorganic salts such as sulfide, phosphide, and heavy metals. , while containing a large amount of organic matter, resulting in higher BOD and COD. [0003] Discharge of domestic sewage without treatment will cause serious environmental pollution such as pathogen pollution, aerobic organic pollution, eutrophication pollu...
