- Abstract:
- In order to improve the water environment of Shenzhen River, pollutant reduction targets were estimated and the total maximum daily load (TMDL) water quality improvement measures were proposed based on analysis of water pollution characteristics and pollution sources. The DO concentration in the water was low, the ammonia nitrogen and total nitrogen in 71% of the cross section exceeded the surface water Ⅴ class standard, and the ammonia nitrogen and total nitrogen increased along the direction of the river. Sewage, industrial wastewater and river sediment in each administrative area were the main sources of water pollution. The pollution contribution of Futian District was the largest. The proportion of sewage discharge was 33%, and the contribution of industrial wastewater discharge to COD and ammonia nitrogen in the river reached 42% and 44%, respectively, which was the key area for pollutants traceability and interception. The remediation plan can achieve the target of completely eliminating black and odor water in 2020 and water quality reaching surface water Ⅴ class standard in 2025 through measures such as interception and dredging, sponge storage, ecological remediation and landscape construction.
