摘要
针对水厂投药系统存在混合絮凝效果差、自动化程度低、投药量大等问题,对投药系统进行了技术改造,并且将混凝剂由聚合硫酸铁更换为聚合铝铁,提高了自动化水平,药耗降低22%,节约药剂费用为34万元/a,节约了制水成本,在很大程度上降低了工人的劳动强度。
In order to solve problems of chemical dosing system in water supply plant, such as poor mixing and flocculation effect, low automation and large chemical dosage, the technical reconstruction of chemical dosing system was performed, and polymeric ferric sulfate was replaced by polymeric aluminum ferric chloride. The automation level is improved, the chemical consumption is reduced by 22%, the chemical cost of 340 000 yuan is saved annually, and the labor intensity is reduced.
