Strategy & Thoughts for Water Environment Improvement of Fengjiang River Basin
Fengjiang River,originating from Dengtang Town in Chaozhou City,its deep pit cross-section had been added as a national monitoring section during the"14th Five-Year Plan"period.Due to excessive ammonia nitrogen,the water quality has failed to meet standards for three consecutive years,was under supervision by the provincial e-cological environment protection inspection office.Aiming at meeting national assessment requirements,Chaozhou City has organized and implemented the Fengjiang River Basin water environment remediation project to improve water quality.Based on the practical implementation,the present water environmental conditions of the basin before remediation are illustrated,the causes of excessive ammonia nitrogen are analyzed.According to the issues of river pollution,inadequate coverage of sewage treatment plants and associated pipelines,severe external water intrusion,and poor maintenance,strategies for the water environment remediation are proposed.By comparing national moni-toring section sampling data before and after remediation,the remediation strategies are verified to be effective.The remediation experience is concluded,which can provide useful references for similar water environment remediation projects in other river basins.
