Gelatin Absorption and Heavy Metal Removal Technology and Application in Municipal Sludge Treatment

凝胶吸附技术用于污泥中重金属去除较传统技术具有成本低、效率高的优势,介绍了凝胶吸附技术的原理、目前国内外相关研究进展情况、国内污泥处理重金属现状以及需要解决的技术问题;通过中试案例的运行效果分析,得出结论:凝胶吸附除重技术已经部分具备工业化应用的技术可行性。

The gelatin absorption technique is used to remove the heavy metals in the sludge. It is provided with theadvantage of low cost and high efficiency in comparison with the traditional techniques. The paper presents the principle ofgelatin absorption technique, progress of research at home and abroad, status of heavy metals of sludge treatment in the countryand the technical problems to be solved. Based on the operation effect analysis of the medium test cases, the conclusion ismade. The result shows that the gelatin absorption and heavy metal removal technology possesses the technical feasibility ofindustrialization application partly.
