复合微生物菌剂在黑臭河道治理中的应用

Application of compound microbial inoculants in the treatment of black and stinky river

工业发展在改善社会经济的同时也对生态环境造成了破坏,近年来河道污染和生态系统失衡现象日益严重,其所出现的常年水体黑臭现象更是对人们生活质量造成了严重的威胁。本文为寻求一种快速有效的黑臭河道治理技术,特以宁大东河为例,通过开展试验,重点明确复合微生物菌剂在黑臭河道治理中的应用效果。试验研究表明:通过投加复合微生物菌剂,水体中的pH、Do、CODMn、BOD5/CODMn、氨氮、总氮、总磷均有明显好转,黑臭现象得到基础上消除与控制,充分表明复合微生物菌剂在黑臭河道治理中的应用效果显著。

While industrial development improves the social economy,it also causes damage to the ecological environment.In recent years,river pollution and ecosystem imbalances have become more and more serious.The perennial black and odor phenomenon of water bodies has caused a serious threat to people’s quality of life..In this paper,in order to find a fast and effective treatment technology for black and stinky rivers,we take Ningdadong River as an example to clarify the application effect of compound microbial inoculants in the treatment of black and stinky rivers by conducting experiments.Experimental research shows that by adding compound microbial inoculants,the pH,Do,CODMn,BOD5/CODMn,ammonia nitrogen,total nitrogen,and total phosphorus in the water are all significantly improved,and the black odor phenomenon is eliminated and controlled on the basis,which fully shows The application effect of microbial inoculants in the treatment of black and odorous rivers is remarkable.
