Environmental river sewage treatment bacteria for natural degradation of pollutants

Since the 1960s, facing the river pollution and serious damage caused by the industrial explosion, European and American countries gradually pay attention to river treatment and sewage treatment.  In the eighties of the last century, with the progress of modern ecology, we deepen the understanding of river sewage treatment engineering needs to follow the basic principles of ecology, clearly put forward the development concept of constructing multi-natural river treatment.  

Most scientists build green ecological river course treatment is pointed out in the protection of river channel governance refers to the security, under the prerequisite of using building green ecological river and the ecological revetment engineering key technology such as, to shape a more natural stability and open river ecosystem health, can maintain for a long time river ecological diversity and ecological balance, and then build a water harmonious ideal environment.

General methods of river sewage treatment

1. Physical methods, such methods often treat the symptoms rather than the root cause.   

1. Chemical method But the river sewage treatment method is easy to cause secondary pollution.   

2. Bioremediation technology 

Bioremediation refers to the use of microorganisms and other living things.  The engineering technology system will degrade the toxic and very harmful pollutants in the water body or soil structure into CO2 and water on site, or transform them into non-toxic and harmless substances.  There are two types of bioremediation technology for river sewage treatment.  One is to directly add one or more kinds of microorganism species after culturing and screening to the polluted river treatment water body

The other is to add microbial growth promoters (nutrients), such asbacteria activators, to the treatment water of polluted river courses to promote the growth of "indigenous" microorganisms.  After the drug is put in, the growth promotion effect is used to promote the growth of pollutant degradation microorganisms, and the microbial succession from anaerobic to aerobic in river management, and the biological succession from low to high, and the biological diversity continues to increase, so that the BOD5 and COD of polluted water rapidly decrease, the dissolved oxygen rises significantly, and the black and odor is eliminated.  This method for the elimination of water black odor, increase water dissolved oxygen effect is obvious.
