- Title:
- Pollution Characteristics Analysis and Control Measures of Shenzhen River
摘要:- 為提高深圳河的水環(huán)境,在水體污染特征分析及污染源解析的基礎(chǔ)上,對污染物削減目標(biāo)進(jìn)行了估算,并提出了最大日負(fù)荷總量(TMDL)水質(zhì)改善措施。結(jié)果表明,水體中DO濃度較低,71%的斷面水體中氨氮和總氮濃度超出地表Ⅴ類水質(zhì)標(biāo)準(zhǔn),且氨氮和總氮濃度均沿河流方向升高。各行政區(qū)中生活和工業(yè)廢水及河道底泥是水體污染的主要來源,福田區(qū)污染貢獻(xiàn)占比最大,生活污水排放占比為33%,工業(yè)廢水排放對河道COD、氨氮的貢獻(xiàn)率分別達(dá)到42%、44%,是溯源截污的重點(diǎn)區(qū)域。通過截污清淤、海綿調(diào)蓄、生態(tài)修復(fù)及景觀營造等措施,可以實(shí)現(xiàn)2020年全面消黑及2025年水質(zhì)達(dá)到Ⅴ類水的目標(biāo)。
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.
