Abstract
In response to water pollution caused by industrial wastewater,domestic sewage,etc.,physical,chemical,and biological remediation technologies are used for treatment.By establishing experimental models,the removal effects of technologies such as flocculation precipitation,activated carbon adsorption,and microbial degradation on pollutants such as heavy metals,organic matter,and nitrogen and phosphorus were tested.Experimental data shows that the Chemical Oxygen Demand(COD)removal rate of the composite bioremediation technology is over 85%,the total nitrogen removal rate reaches 75%,and the heavy metal removal rate exceeds 90%.At the same time,the recovery of aquatic plant communities was good,and the diversity index of plankton increased by 1.5 times,confirming the practical application value of water pollution remediation technology in ecosystem restoration.关键词
