【摘要】 对沸石处理含磷废水进行了试验研究,探讨了沸石用量、废水酸度、接触时间、温度及磷酸盐浓度对除磷效果的影响。结果表明,在废水pH值2-10、磷浓度0-100 mg/L范围内,按磷与沸石重量比为1:200投加沸石进行处理,磷去除率可达90％,且处理后废水pH值近中性。更多还原

【Abstract】 The treatment of phosphate-containing wastewater with zeolite was studied in the laboratory, and also the effects of zeolite quantity, acidity of wastewater, contacting time, temperature and phosphate content was dis-eussed. Results showed that phosphate removing effieiency reached 90% and the pH value was near neutral after treatment while the weight ratio of phosphate and zeolite was 1/200 in the wastewater containing 0 - 100 mg/L phosphate of pH 2 ~ 10.更多还原
