摘要
矿山废水的处理是当前我国有色金属矿山面临的环境保护的重大研究课题之一.
本研究以湖南省郴州市杮竹园多金属矿1000t/d选厂废水处理系统为研究对象,在以前研究问题的基础上,针对当前柿竹园选矿废水形成和处理利用现状以及存在的问题进行研究设计,分别从废水处理工艺选择和废水处理厂的设计进行改进.在工艺选择中进行石灰石中和改进工艺和中和-配合-回流工艺的介绍,废水处理厂设计最终采用石灰石中和改进工艺,石灰石中和改进工艺中和、沉降、絮凝、澄清及污泥处理系统五个处理工序,通过各个工艺参数的控制,使废水达标排放.本工艺的主要特点是:
废水处理系统设计为无人值守的形式,涉及到很多独立的小系统.废水处理过程还涉及到化学反应平衡的控制,也就是说控制系统存在滞后环节(如pH值的控制),因而要使这一系统稳定运行并使废水达标排放要做相当多的工作.根据废水的流量计算加入反应器的各种化学药品,使化学处理能正常进行.通过在出水箱中加人HC1调节最终出水pH值.当出水浊度不合格时,采用停止废水进入系统,将出水箱中的水重新打回至中和反应池中,进行再处理.澄清池中污泥的自动排放.通过澄清浓缩池中的泥位检测仪测量澄清池中的污泥量,控制系统根据污泥的高度实现对罐中的污泥向压滤机排放的控制.
最后,分别从厂址选择、总平面布置、高程布置、主要构建物、设备及投资估算进行选矿废水处理厂设计.
关键词:选矿废水;处理工艺;用水;排水;中和;

Abstract
Mine wastewater treatment is currently facing China's nonferrous metal mines environmental protection one of the major research topic.
In this study, Chenzhou City in Hunan Province polymetallic ore market Chuk Yuen 1000 t / d election plant wastewater treatment system for the study, in the previous study, based on the view of the current form Shizhuyuan processing wastewater treatment and the status quo and the use of the existing problems Research and design, from wastewater treatment process selection and design of wastewater treatment plant improvements. In the process of selection and improvement in the conduct of limestone and in the process and - with - the return process, the final design of wastewater treatment plant and improve the use of limestone in the process, and limestone in the process of improving and that the settlement, flocculation, clarification and sludge Five processing system processes, through various technical parameters of control, waste water discharge standards. The main characteristics of this process is:
Wastewater treatment system designed for unattended in the form of many small independent system. Waste water treatment process also involves the chemical reaction balance control, control system that is lagging sectors (such as the pH value of control) and thus to make the system stable operation of wastewater discharge standards and a lot of work to be done. According to the flow of waste water reactor calculated by adding the various chemicals, chemical treatment to normal. By adding a water tank in the final HC1 adjust pH of the water. When the water turbidity failed, to stop use of wastewater into the system, will be out of the water in the tank to fight back and in response to the pool, re-processing. To clarify the automatic discharge pond sludge. By clarifying concentrated pool of mud-detector measurement clarify the pool of sludge volume, the control system, according to achieve a high degree of sludge in the tank sludge to filter emission control.
Finally, from site selection, general layout, elevation layout of the main building, equipment and investment estimates for processing waste water treatment plant design.
