摘　　要：对江浙沪中小蓄电池企业污水化学耗氧量进行了抽样调查，旨在为综合治理水环境提供参考依据。水样中加入硫酸汞、硫酸一硫酸银溶液和重铬酸钾溶液，混匀后微波消解，冷却后，用紫外可见分光光度计测定。结果显示，排污口污水化学耗氧量为8．64～51．60mg／L。排污系数为2．76-38．06kg／（10^4kVAh）。由此可知，水样经处理后，排污口污水化学耗氧量明显小于产污口污水化学耗氧量，铅酸蓄电池厂的排污口污水化学耗氧量均小于标准限值100mg/L，符合国家污水综合排放标准，但必须控制污水总排放量，从而控制污水总化学耗氧量。Aiming at providing reference for comprehensive administration of water environment, sampling survey was carded out with regard to the chemical oxygen demand （COD） level of sewage produced by small and medium battery enterprises in Jiangsu, Zhejiang and Shanghai. HgSO4, H2SO4-Ag2SO4 and K2Cr2O7 solution were added into the sewage sample, and after blending, then microware digestion and cooling, the sample was assessed using UV-VIS spectrophotometer. The results show that sewage COD level at the outlet was from 8.64 to 51.60 mg/L with sewage discharge coefficient varying from 2.76 to 38.06 kg/（10^4 kVAh）. After disposal, the COD level of sewage at the outlet is apparently lower than that of the original sewage producing export. The COD level of sewage at the export of lead-acid battery plants is lower than the standard limitation 100 mg/L, meeting the National Standard for Comprehensive Sewage Discharge, but total sum of sewage must be reined to control the total COD level.
