Description

technical field

[0001] The invention belongs to the technical field of water treatment, and in particular relates to a domestic sewage treatment agent. Background technique

[0002] With the improvement of people's living standards, the discharge of domestic sewage is becoming more and more serious. Domestic sewage is mainly various wastewater generated in people's daily life, mainly washing sewage, which contains a large amount of cellulose, starch and sugar. It also contains inorganic salts such as chloride, sulfate, phosphate, etc. It is characterized by high content of nitrogen, phosphorus, and sulfur, and it is easy to produce foul odor under the action of anaerobic bacteria.

[0003] In recent years, the treatment process of domestic sewage has also been continuously improved, including biological treatment methods and physical treatment methods. The biological method takes a long time, slow speed and low efficiency; the physical treatment method is expensive, and the...
