Equipment, realize denitrogenation and ultra-filtration filters processing efficiently, stable, realize environmentally friendly production requirement.
Background technology
Sewage, is often referred to discharge water necessarily polluted, from life and production, and sewage mainly has sanitary sewage, work
Industry waste water and early-stage rainwater, the ill pathogen contaminant of major pollutants, oxygen consumption pollutant, plant nutrient and the poisonous dirt of sewage
Contaminate thing etc..
According to the viewpoint of sewage source, sewage can be defined as from the discharge of house, office, business or industrial area and ground
The liquid or water that carry waste of the mixing such as lower water, surface water, snowstorm.Sewage is correspondingly reduced dirty by many classifications
Influence of the water to environment also has many technologies and technique.According to sewage source, sewage can be divided into this four class.The first kind：Industry
Sewage of the waste water from manufacturing, mining and industrial production activities, including lived from the runoff stored, processed with industry or business
Leachate site, and it is other be not sanitary sewage waste water.Second class：Sanitary sewage is from house, office building, office or similar
Sewage；Hygienic sewage；The industrial wastewater mixed in effluent sewerage, including sewerage system in sanitary sewage.3rd class：Business
Industry sewage exceedes nontoxic, the harmless sewage of sanitary sewage from commercial facility and some compositions.Such as sewage from catering business.Laundry
Sewage, animal feeding sewage, sewage etc. caused by hairdressing place.4th class：Overland flow water under rainwater, snow-broth, highway,
Water from city and industrial area etc., overland flow does not infilter soil, enters underground water along street and land.
