Description
Technical field
The present invention relates to water-treatment technology fields, and in particular to a kind of processing method of sanitary sewage.
Background technique
Water is essential natural resources in human being's production and life, and the environmental resource depended on for existence of biology, with
Water resources crisis aggravation and water resource quality constantly deteriorate, shortage of water resources has evolved into what the whole world was paid close attention to jointly
Problem, and greatly developing method for treating water will play a crucial role for solving this technical problem of shortage of water resources.
Sanitary sewage is a kind of sewage that specific gravity is increasing in present society, is produced to natural environment and human lives
Very big influence, nitrogen, phosphorus, the fat content in sanitary sewage are higher, traditional water process reagent include coagulant/flocculant,
Fungicide, antisludging agent etc., but often function is all more single, and there are many kinds of, dosage is big, the device is complicated, cumbersome
Etc. problems, and between different medicaments it is also possible to mutually inhibit, reduce the efficiency of water process.Using traditional sewage
Reagent treatment often expends a large amount of manpower and material resources, and effect is also less obvious, and the use of a large amount of chemical agents can also make environment
At burden.
