Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen sewage treatment, and specifically relates to a sewage purification device. Background Art

[0002] Kitchen sewage refers to high-concentration organic sewage containing edible waste oil after solid-liquid separation of restaurant kitchen waste. The composition of kitchen sewage is relatively complex, and it contains various organic matter, animal and vegetable oils, proteins, sugars, starches, etc. In urban life, large shopping malls and catering businesses are concentrated, kitchen sewage is concentrated, and the sewage discharge volume is large. Compared with domestic sewage, sewage pollution indicators have similar composition but high organic content and contain a large amount of animal and vegetable oils. If it is discharged directly into the municipal sewage pipe without pretreatment, it will cause great harm. Grease is easy to coagulate and agglomerate in the sewer pipe, causing blockage of the sewage pipe and even paralysis of the entire urban sewage network.
