In the paper the repairing and treatment technology of polluted river was summarized, which were chemical, physical and bioremediation technologies. Chemical techniques include chemical alga-killing, heavy-metal fixer. Physical techniques include artificial aeration, polluted watercourse flushing, sediment dredging. Bioremediation techniques include microorganism strengthen, plant strengthening, bio-film...
The underground infiltration sewage treatment system has invests, the equipment to be simple few, the expense is low, management simple and so on characteristics. Through increase voluntarily the development's microorganism microbial inoculum improvement soil character and in the enhancement underground infiltration system microorganism activeness, and carries on the microbial inoculum the physiological...
Antibiotics into the environment through after adsorption, transport and degradation of a series of bio-transformation process gradually removed from the environment. The degradation of antibiotics in the environment are mainly hydrolysis, photolysis and biological degradation, etc.. Biodegradation is the main way most of the degradation of antibiotics, including the degradation of drug-resistant...
Oxidation ditch process in the ecological dosing microbial agents KS-60, on the bioremediation of polluted rivers simulation. In the experiment studied the KS-60 bacterium, aeration, bio-carrier for purifying effect. The results showed that dosing KS-60 antimicrobial can reduce the river of COD, ammonia nitrogen and total phosphorus turbidity, in a state of bio-carrier, its purification is more prominent,...
Two kinds of pilot subsurface wastewater infiltration system (SWIS), named group A and group B were constructed in the laboratory. Group A was filled with mixed substrates composed of 80% meadow brown soil (MBS) and 20% cinder, while 80% MBS and 20% sand in group B. Both of the SWIS worked stably in an intermittent feeding mode during the period of the experiment. Under the hydraulic loading of 8-10m...
