Description
Technical field
The present invention relates to sewage treatment field, more particularly to a kind of domestic sewage of villages and small towns inorganic agent and preparation method thereof.
Background technology
Produced by sanitary sewage is mainly used in human lives various water for kitchen use, slurry and use in toilet water
Discharge water, be mostly nontoxic inorganic salts.The sewage produced during human lives, is one of primary pollution source of water body.
Mainly excrement and wash water.Everyone sanitary sewage amount discharged daily of city is 150-400L, its amount has with living standard
Substantial connection.Contain large amount of organic, such as cellulose, starch, carbohydrate and fat protein in sanitary sewage；Also often containing ill
Opportunistic pathogen, virus and parasitic ovum；Chloride, sulfate, phosphate, bicarbonate and the sodium of inorganic salts, potassium, calcium, magnesium etc..Always
The characteristics of be nitrogenous, sulfur-bearing and phosphorous height, in the case where anaerobic bacteria acts on, easily raw odorant.
While living standard improves, life style does not change rural resident therewith, also according to tradition
Lifestyle, the sanitary sewage of rural resident is mostly directly to be poured on Around the house, the mode of this sewage effluent, no
But sewage is flow over, influence look of a village, and sewage permeates the ground for a long time, nitrogenous in sanitary sewage, phosphorus, and sulphur is more, pathogenic bacteria is more,
Rural groundwater quality is caused to deteriorate.The simple running water or Hand pump well in most of rural areas are directly taken without any processing
Underground water is drinking water, and very big threat is caused to the health of people.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.
