Description
Technical field
The present invention relates to sewage treating material technical field, be specifically related to a kind of process material for pathogen sewage and using method thereof.
Background technology
Although the earth has the area of 70.8% to be covered by water, but freshwater resources are extremely limited, and really being able to by our utilization is the part in rivers and lakes and subsoil water, and these only take up an area the 0.26% of ball total Water, and skewness.After the fifties in last century, population in the world sharp increase, industrial boom, incident is that the rapid of global water resources situation deteriorates, and " water crisis " is on the rise.On the one hand it is that the demand of water resource is increased by the mankind with surprising rapidity；On the other hand, the water being on the rise pollutes nibbles the water resource being available for consumption in a large number.
Water pollution condition is constantly aggravated, cause people more and more to pay close attention to, the trade effluent that especially various places generally exist pollutes, and the improvement attention rate containing pathogen and the sewage of various pollutant such as the waste water that sanitary sewage, medical sewage, its feeding field sewage and process hides, scouring of wool, butchery etc. are discharged little, wouldn't know that this type of sewage often contains various pathogen, such as pathogenic bacteria, virus, parasite, water body can be propagated multiple disease by the pollution of pathogen, such as schistosomicide, typhoid fever, cholera, viral hepatitis, dysentery etc..
The feature of pathogen contamination is: quantity is big, distribution is wide, time-to-live length, reproduction speed are fast, be easily generated Drug resistance, is therefore difficult to die out.After traditional secondary biochemical sewage disposal and chlorination, some pathogenic microorganism and virus remain to substantial amounts of survival.Coagulation in conventional sewage water treatment method, precipitate, filter, disinfect and can remove more than 95% virus in water, but conventional sewage treating material is bad to the removal effect of dirty impurities in water, still can the penetrating or the parasitism of pathogenic microorganism of associated virus.Pathogen contamination thing can enter water body by number of ways, once runs into applicable condition, will cause human body diseases.
