摘要:
针对低C/N值微污染水体带来的水质安全及富营养化问题，探索了微米零价铁粉(mZVIP)与人工快渗(CRI)协同体系深度处理微污染水体的效能，研究了mZVIP体积占比、湿干比和水力负荷周期对mZVIP/CRI协同体系去除COD、NH4+-N、TN和TP的影响，获得了协同体系的优化运行条件。结果表明，协同体系在湿干比为1 ∶3、水力负荷周期为24 h、mZVIP体积占比为10%的优化条件下，出水COD、NH4+-N、TN和TP平均浓度分别为（9.88±2.04）、（0.20±0.05）、（13.84±0.93）和（0.071±0.011） mg/L，与传统CRI系统相比，去除率分别提高了12.66%、13.30%、20.73%和4.24%，满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准，mZVIP/CRI协同体系具有处理低C/N值微污染水体的可行性。
Abstract:
Aiming at the problems of water quality safety and eutrophication caused by low C/N ratio micro-polluted water body, the advanced treatment efficiency of micro-polluted water body by a coupled system of micro zero valent iron powder (mZVIP) and constructed rapid infiltration (CRI) was explored. Effects of mZVIP volume ratio, wet-dry ratio and hydraulic load cycle on the removal of COD, NH4+-N, TN and TP by the mZVIP/CRI system were investigated, and the optimal operating conditions of the system were determined. The optimal operating conditions of the coupled system were as follows: wet-dry ratio of 1 ∶3, hydraulic load cycle of 24 hours and mZVIP volume ratio of 10%, and the average concentrations of COD,NH4+-N, TN and TP in effluent were (9.88±2.04) mg/L, (0.20±0.05) mg/L, (13.84±0.93) mg/L and (0.071±0.011) mg/L, respectively. Compared with traditional CRI system, the removal efficiencies were improved by 12.66%, 13.30%, 20.73% and 4.24%, respectively. The effluent quality met the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), indicating that the coupled system was feasible to treat micro-polluted water body with low C/N ratio.
