摘要
水资源是矿区经营发展不可或缺的重要组成部分,高效处理矿井水可以在一定程度上缓解矿区缺水等问题.本项目首次提出了井下百米陶瓷膜处理煤矿矿井水工艺,其装置设计结构紧凑,占地面积为传统工艺的1/10.对比了"混凝沉淀+砂滤+有机超滤+反渗透"工艺及"陶瓷膜+反渗透"工艺.结果显示:"陶瓷膜+反渗透"集成工艺处理矿井水的出水化学需氧量(CODCr)质量浓度为7.2 mg/L,NH3-N质量浓度为0.12 mg/L,对固体悬浮物(SS)和浊度具有100％的去除效果,陶瓷膜集成工艺在矿井水处理领域展现出了广阔的应用前景.
Abstract
Water resource is an indispensable part of mine management and development.Efficient treatment of mine water can alleviate the problems of mine water shortage to a certain extent.This project proposes the process of underground ceramic membrane treatment of coal mine water for the first time,and its device design is compact and occupies 1/10 of the traditional process.The process of"coagulation sedimentation+sand filtration+ultrafiltration+reverse osmosis"and the process of"ceramic membrane filtration+reverse osmosis"were compared.The results show that the chemical oxygen demand(CODCr)concentration and NH3-N concentration are 7.2 mg/L and 0.12 mg/L respectively in the treatment of mine water by the integrated process of"ceramic membrane+reverse osmosis",which has a 100％removal effect on suspended solids(SS)and turbidity.Ceramic membrane direct filtration technology has shown a broad application prospect in the field of mine water treatment.
