无机粘土系聚沉剂处理造纸废水的研究

利用无机粘土系聚沉剂处理造纸废水，并结合曝气等做进一步的深化处理，收到较好的处理效果，经测定出水的化学耗氧量去除率可达到８５％以上，五日生物需氧量（ＢＯＤ５）为４４５ｍｇ／Ｌ，该法处理造纸废水，操作简单，费用低，且处理效果好。

Study on the Pulp Water Treatment by Inorganic Clay Coagulant

Inorganic clay coagulant is a kind of fine water purificatio n agent and applied extensively to the treatment of waste water, especially for pulp water. To combinate with aeration for deep treatment, the coagulating effectiveness can be increase. After determination, the COD cr detersive efficiency of effluent reaches 85% and the BOD 5 is 445mg/L. In a word, the method is easy to control and the cost is cheap, so it has remarkable enconomic and social benifit.
