Abstract
The invention discloses a medicament for reducing the COD (Chemical Oxygen Demand) of domestic sewage. The medicament consists of coal slag, quick lime, ferric sulfate, hydrogen peroxide and sulphur in the weight ratio of 100: (5-10): (0.5-0.8): (0.1-0.3): (2-3). The medicament disclosed by the invention can effectively reduce the COD index of the domestic sewage, and the treatment cost of the sewage is reduced.
Description
Technical field
The invention belongs to sewage treatment area, be specifically related to a kind of medicament reducing sanitary sewage COD.
Background technology
China's Water Pollution Prevention Law specifies that the trade effluent in the sewage that the crowd settlement disperseed the Residential areas can not including municipal sewage collection system system in, tourist attractions, holiday village, sanatorium, airport, railway station, economic and technological development zone etc. is discharged and the land of independent industries and mining district answers treatment in situ qualified discharge.Unprocessedly enter rivers, can cause serious harm, as the existence etc. occurring body eutrophication phenomenon, affect water supply source, increase Water purification cost harm humans and biology, existing sewage disposal investment is large, and working cost is high.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of medicament for reducing sanitary sewage COD.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
Reduce a medicament of sanitary sewage COD, described medicament is 100:(5-10 by cinder, unslaked lime, ferric sulfate, hydrogen peroxide and sulphur by weight): (0.5-0.8): (0.1-0.3): (2-3) forms.
