采用次氯酸钠对南方某水厂砂滤池出水进行消毒,研究次氯酸钠投加量、细菌总数和总大肠菌群、 pH值对次氯酸钠杀菌效果的影响。结果表明,随着次氯酸钠投加量的增加,余氯浓度不断升高,处理后水中的细菌不断减少；次氯酸钠对试验范围内不同的细菌总数和总大肠菌群数都有很好的杀菌效果； pH值的变化对细菌和总大肠菌群生长无影响,起灭菌作用的是次氯酸钠。次氯酸钠对微生物的杀菌效果显著,选择最佳次氯酸钠的投加量为1.5 mg/L,出水的菌落总数和总大肠菌群完全达到GB 5749-2006《生活饮用水卫生标准》的要求,微生物安全性可以得到保障。
採用次氯痠鈉對南方某水廠砂濾池齣水進行消毒,研究次氯痠鈉投加量、細菌總數和總大腸菌群、 pH值對次氯痠鈉殺菌效果的影響。結果錶明,隨著次氯痠鈉投加量的增加,餘氯濃度不斷升高,處理後水中的細菌不斷減少；次氯痠鈉對試驗範圍內不同的細菌總數和總大腸菌群數都有很好的殺菌效果； pH值的變化對細菌和總大腸菌群生長無影響,起滅菌作用的是次氯痠鈉。次氯痠鈉對微生物的殺菌效果顯著,選擇最佳次氯痠鈉的投加量為1.5 mg/L,齣水的菌落總數和總大腸菌群完全達到GB 5749-2006《生活飲用水衛生標準》的要求,微生物安全性可以得到保障。

Using sodium hypochlorite(NaClO) to disinfect the effluent water from the sand filter of a water works, the influence of NaClO dosage, total bacterial counts, total coliform groups, and pH value on sterilization effect of NaClO were studied. The results showed that, with the increasing of NaClO dosage, the effluent chlorine residual concentration increased and the bacteria decreased continuously; NaClO had good sterilization effect on the total bacterial counts and the total coliform groups within the scope of the test; the change of pH value had no effect on the growth of bacteria and total coliform groups, the one played a part in sterilization was NaClO. It could be seen that, NaClO had an obvious bactericidal effect, and its optimal dosage was 1.5 mg/L. Using it to treat wastewater, the total bacterial counts and total coliform groups in the effluent water could meet the require-ment of Standards for Drinking Water Quality, the safety of microorganism could be ensured.
