Description
Technical field
The present invention relates to sewage water filtration technical fields, and in particular to a kind of efficient sanitary sewage filter plate and its preparation side
Method.
Background technology
Sanitary sewage is the waste water discharged in resident's daily life, and pollutant contained therein is mainly organic matter (such as egg
White matter, carbohydrate, fat, urea, ammonia nitrogen etc.) and a large amount of pathogenic microorganisms (such as parasitic ovum and enteric infection virus
Deng), the organic matter being present in sanitary sewage is extremely unstable, easily degenerates and generates stench, and bacterium and pathogen are with dirt of living
Organic substance in water amount reproduction for nutrition can cause infectious disease from spreading popular, therefore, must be located before sanitary sewage discharge
Reason.
In the treatment process of sanitary sewage, simple precipitation, filtering or appropriate aeration are first passed through, to remove in sewage
Suspended matter, in the prior art, some technique promote the close to each other and aggregation of suspended matter in sewage using addition flocculant, make
It is in an unsure state and precipitates, therefore flocculant is widely used in sewage treatment field.Flocculant it is various in style, from
Low molecule is to develop to cheap practical, non-toxic efficient direction from single type to compound, total trend to macromolecule, inorganic
Flocculant it is cheap, but human health and ecological environment can be had adverse effect on；Although organic polymer coargulator
Dosage is few, and scum silica frost yield is few, and flocculation ability is strong, and flco can be easily separated, and degreaser oil removal effect is good, but this kind of high polymer
Residual monomer has " three cause " effect (teratogenesis, carcinogenic, mutagenesis), thus is restricted its application range.Also the use having
