1、 I xx 工业废水处理及再生回用工程设计 摘摘 要要 以紫金矿业集团处理规模为 10000m3/d 重金属废水处理工程为例，介 绍了升流式厌氧污泥反应床(UASB)和膜生化反应器(MBR)联合处理工艺在 重金属废水处理中的应用情况。 工艺首先采用厌氧工艺降低处理水体的有机物负荷，在水体中有机污 染物浓度得到一定降低的条件下， 采用 MBR 工艺进一步降低水体中的有机 污染物浓度。经过处理后，出水水质达到铜、镍、钴工业污染物排放标 准，回用水达到生活杂用水水质标准要求。 通过计算确定了工艺流程中主要设施的尺寸以及设备的型号。计算分 析表明，设计处理出水水质达到且优于国家相关标准。对设施运行成本

2、的 估算证明，该流程在处理成本上有实施的可能。 关键词：矿业废水；升流式厌氧污泥床；中水回用；膜生物反应器 Zijin Mining Group of Heavy Metal Industrial II Wastewater Treatment and Reuse Project Design Abstract By using the practical engineering in Zijin Mining Group with the scale of 10000 m3/d waste Heavy metal waste water treatment .

3、oduces the application of Up-flow Anaerobic Sludge Bed (UASB) and Membrane Bio-Reactor (MBR) combined process in Heavy metal waste water treatment. Anaerobic technology is firstly used to reduce the orgaeic load- ing and MBR process is used to further reduce ammonia and organic pollutants under the

4、conditions of a certain reduction of the organic pollutants in waste- water. After treatment, water quality standards of the drained water, water reuse back to water standards. The article designs and calculates the parameters of the structures and the equipments in the treatment. The results of the calculations and analysis on Reclaimed Water treatment technology indicates that the treated water can achieve the relevant standards. By analyzing the handling costs, it is proved that the tre
