As a kind of improvement of this programme, each substance is dusty material in the sewage-treating agent, and partial size is no more than 0.2mm.
As a kind of improvement of this programme, in step d, the quality and sewage mass ratio of sewage-treating agent addition are 1:
20-1:10.
The utility model has the advantages that a kind of purifying domestic sewage method of the present invention, the addition for various additives of making rational planning for are suitable
Sequence has the function that purifying domestic sewage, without using equipment such as destilling tower, air floatation machines, clarifier-tank is used only, subtracts significantly
Few equipment cost.
In step b, level-one sewage purifier carries out preliminary purification processing to sewage by way of physical absorption.Step c
In, by adding oxidant, kill microorganism in water, and impurities in water waddingization made by flocculant, facilitate it is clear, in step d
Organic substance in water is further processed using a kind of sewage-treating agent.
It include diatomite in used sewage-treating agent, diatomite inhales the substances such as grease, protein, fiber in water
Attached precipitating, achievees the purpose that purification.Calcium carbonate is porous structure, in conjunction with diatomite, on the one hand be can be used as micro- in diatomite
Biological medium improves diatomite catharsis, on the other hand can be with physical absorption impurities in water.Utilize the sewage treatment
Agent dirt in flocculation water and can inhibit the growth of microorganism in water.
Treated sanitary sewage, which is sent into after waterworks carries out conventional treatment, can be used to living water.
A kind of purifying domestic sewage method, process is reasonable, and step is simple, and equipment investment is few, good purification, fits
It closes and promotes the use of.
