浙江省污水处理厂COD减排贡献率及风险分析

Contribution Rate of WWTPs to Reduction of COD Discharge and Risk Analysis in Zhejiang Province

对近三年来浙江省的COD产生量、去除量和排放量以及全省污水处理厂的COD去除量进行了对比分析,探讨了污水处理厂COD减排贡献率的变化趋势。根据对单位GDP产生不同COD量的预期,预测了浙江省"十一五"期末和2020年COD总产生量和减排目标,分析了污水处理厂COD减排的贡献率及风险,并提出了相应对策。

The amounts of COD production, removal and discharge in Zhejiang Province and the COD removal in wastewater treatment plants in the province over the last three years are analyzed. The variation in contribution rate of the wastewater treatment plants to reduction of COD discharge is discussed. The total amount of COD production and the COD discharge reduction objective in Zhejiang Province by the end of 11 th Five-Year Plan and in 2020 are forecasted based on the different amounts of COD produced per unit of GDP. The contribution rate of the wastewater treatment plants to reduction of COD discharge and their risk are analyzed, and the corresponding countermeasures are put forward.
