There are other waste water of above-mentioned ejection.But, the change along with people's living habit and the enhancing to environmental requirement, live now
The category of sewage is the most singly above-mentioned sewage, also includes kitchen drainage and slurry.Existing saying, the life of regulation indication is dirty
Water is defined as " Heisui River ", and kitchen drainage and slurry are defined as " buck ", and they are sanitary sewage.
The sanitary sewage impact on environment
Feces is contained in " Heisui River " based on toilet drainage, and containing a large amount of nitrogen phosphate and sulfurs, too much nutrient in feces
Matter enters natural water body, can promote the green plants amount reproductions such as algae, assembles in waters slowly of flowing and forms sheet
Wawter bloom (in lake, reservoir) or red tide (in ocean).And the death of algae and corruption can cause subtracting in a large number of oxygen in water
Few, make the aquatic organism such as water quality deterioration, Fish dead.It addition, possibly together with cellulose, starch, saccharide, fat, egg in fecal sewage
White matter, carbamide etc. are easily generated the material of stench under Anaerobic Bacteria effect, also can severe contamination inland waters." buck " contains
Some detergent, liquid detergent etc. are also many containing phosphate, can make the algal bloom of korneforos, reduce water oxygen gas so that it is it
Biology suffocates.It addition, the dietary habit of China, determine that the kitchen waste water water yield is big, oils and fats is many, viscosity is high, residue is many, containing many
Plant Organic substance and inorganic salinity, also inland waters can be caused certain pollution.
