The technology of coagulation and flocculation in rare - earth smelting sewage treatment 采用混凝技術(shù)處理稀土冶煉廢水
According to the water supply source used the mining area in bai yun , based on the mechanism of coagulation and flocculation , the feasibility of removing fluoride from water with the method of coagulation and filtration is studied through experiment . and several key parameters which affect defluorination are also analyzed . by using polyaluminum chloride ( pac ) as coagulant , the optimum ranges of the operational parameters are obtained 本文根據(jù)白云鄂博礦區(qū)飲用水的供水水源,以混凝機(jī)理為基礎(chǔ),通過靜態(tài)和動(dòng)態(tài)實(shí)驗(yàn),對用混凝過濾法除氟的可行性進(jìn)行了研究,并對影響除氟因素的幾個(gè)主要參數(shù)進(jìn)行實(shí)驗(yàn)分析,得出了用堿式氯化鋁作為混凝劑進(jìn)行實(shí)際運(yùn)行時(shí),參數(shù)最佳取值范圍。
