摘要
近年来,随着国家经济发展,国家环境问题越来越突出,其中水体富营养化问题至2007年太湖蓝藻爆发后便得到广大关注,而磷是水体富营养化的限制因子,因此除磷便成社会科学研究的热点,国内外对除磷的研究新型技术层出不穷。本文以膨润土作为除磷剂来探究改性的最佳方式,实验发现,膨润土具备一定的除磷能力,经过氯化钙改性后的膨润土能提高去除率10%左右,而此种改性方式在处理受磷污染的生活污水及湖泊水时更为突出,具有较强的适应不同类型污水的能力,能有效的去除水体中磷,起到净化水质的效果。
In recent years, with the development of the national economy,the national environmental problems have become more and more prominent. Among them, the problem of eutrophication of water bodies has received widespread attention since the outbreak of cyanobacteria in TaihuLake in 2007, and phosphorus is a limiting factor for eutrophication of water bodies.As a hot spot in social science research, new technologies for the researc h of phosphorus removal at home and abroad are emerging one after another. In this paper, bentonite is used as a dephosphorization agent to explore the best way of modification. It is found that bentonite has certain dephosphorization ability, and bentonite modified by calcium chloride can increase the removal rate by about 10%, and this modification method It is more prominent when dealing with domestic sewage and lake water contaminated by phosphorus. It has strong ability to adapt to different types of sewage, and can effectively remove phosphorus from water and improve water quality.
