技改工程环境影响评价中的水污染防治措施案例分析

以天津市某电机公司技改工程环境影响评价为例,分析公司各生产工艺排放的废水中各种水污染物的成分以及它们的排放量与排放浓度,评价该公司内原有的生产废水处理站接纳拟建技改工程废水的能力与稳定达标排放的可行性,找出电镀车间污水处理设施排放口处一类污染物Ni超过GB 8978 -1996《污水综合排放标准》的原因,提出合理的污水处理方案,使公司生产废水处理站的排水实现稳定达标排放,由此阐述出环境影响评价对技改工程环境保护治理的技术指导的作用.

Case analysis of water pollution preventive measures in the environmental impact assessment of the technical reform project

This paper analyzed various water pollutants,their emissions and emissions concentration depending on the Environmental Impact Assessment(EIA) of Technical reform in an electrical company.It evaluated the capacity of implementing technical reform in this company’s wastewater treatment station and the feasibility of stability up to the discharge standard in order to find the reason why the one of the first class of pollutants Ni,which was discharged by the outlets of plating factory sewage treatment facilities,exceeded the standard in GB 8978-1996 "Integrated Wastewater Discharge Standard".Then,it provided a reasonable treatment program to make the drainage of the wastewater treatment station reaching the standard requirements.Consequently,it reflected the important role of the environmental impact assessment played in providing a technical guidance for environmental management in the technical reform project.
