摘　　要：由于环保政策的影响,益阳地区许多小型煤矿已经关闭,但它们矿区周围仍有渗漏的水需要持续处理。本项目在早期阶段由于雨水和含镉废水分流不彻底,处理规模与实际的废水排放量存在较大差异,处理流程不尽完善,废水水质的监测和自动控制相对不足,出水水质稳定性存在问题。此外,污泥处理技术相对落后,实际处理能力不足。针对上述问题,我们对雨水和污水处理分流进行了优化,增加了调节池,采用了新型含镉酸性废水一体化处理设备,选择了更经济的药剂,提升了控制系统的自动化水平,并对污泥处理系统进行了改进,实现运行效果的提升及运行成本的降低。Due to the impact of environmental protection policies,many small coal mines in the Yiyang area have been closed,but there is still leaking water around their mining areas that needs continuous treatment.In the early stage of this project,due to the incomplete diversion of rainwater and cadmium-containing wastewater,there is a big difference between the treatment scale and the actual wastewater discharge.The treatment process is not perfect,and the monitoring and automatic control of wastewater quality are relatively insufficient,and there are problems with the stability of the effluent water quality.In addition,the sludge treatment technology is relatively backward and the actual treatment capacity is insufficient.In response to the above problems,we optimized the diversion of rainwater and sewage treatment,added a regulating tank,adopted a new integrated treatment equipment for cadmium-containing acidic wastewater,selected more economical agents,improved the automation level of the control system,and improved the sludge treatment system to achieve the improvement of the operating effect and the reduction of the operating cost.
