Disposal Problem of Arsenic Sludge Generated During Arsenic Removal from Drinking Water 饮用水除砷过程中产生的砷泥处置问题 Part 01 Abstract（摘要) 1.Arsenic (As) causes acute and chronic toxicity,it harm the skin and associated with increase risk of cancer in the skin,bladder and kidney. 砷（As）会引起急性和慢性毒性，它会伤害皮肤，并增加皮肤癌，膀胱癌和肾脏癌的风险。 2.It is very difficult to diagnose the early symptoms of arsenicosis so it depends largely on awareness with improving the quality of drinking water. 诊断砷中毒的早期症状是很难的，因此这在很大程度上取决于提高改善饮用水的质量意识， 3.There are several methods are available for removal of As from water. 有几种方法可用于去除水中的砷。 Part 01 Abstract（摘要) 4.The mostcommonly used technologies are oxidation, co-precipitation, adsorption, absorption, coagulation（凝结）, ion-exchange resin, lime treatment and membrane techniques. 最常用的技术是氧化、沉淀、吸附、吸收、混凝、离子交换树脂、石灰治疗与膜技术。 5.Now today the safe disposal of large quantity of As contaminated sludge generated from As removal water treatment plant which contain about 5-7 kg of arsenic per cubic meter due to risk of underground water contamination as arsenic has very high leaching potential. 现在作为去除水处理厂所产生的大量污染污泥的安全处置，由于地下水的风险，每立方米立方米的含砷量约为5-7公斤砷污染具有很高的浸出潜力。 6.For safe disposal of solid hazardous waste of As requires treatment. 为安全处置固体危险废物的As需要处理。 Part 01 Abstract（摘要) 7.Along term solution appears to solidification/stabilization (s/s) of As-sludge and using it for beneficial purposes like bricks andconcretes etc. 随着长期的解决方案出现固化/稳定（S / S）的污泥，并使用它的有益用途，如砖和混凝土等。 8.In the field of active research, this paper identifies the gap between the implementation of process as well as newtechnologies for safe disposal of arsenic sludge. 在活跃的研究领域，本文识别过程的实施之间的差距以及含砷污泥安全处置新技术。 9.Kevwords.Arsenic Sludge, Arsenic Removal Drinking Water 关键词：砷污泥，除砷的饮用水 Part 01 Introduction（前言) Introduction Arsenic is a naturally occurring semi-metal element present in the environment in both inorganic and organic forms. Inorganic arsenic is considered to be the most toxic form of the element
