预处理+超滤的一体化净水装置的试验研究

Experimental Research on Integrative Water Purification Equipment with Pretreatment+UF

以一体化净水装置，采用预处理＋超滤工艺处理长江水，产水量大．在进水流量16．83～17，67L／min情况下，出水流量15.00～16．40L／min，出水流量相当于进水流量的89．0％～93，0％；出水水质好，对浊度和有机物都有很好的去除效果，对浊度的去除率达到了99％以上，出水浊度仅在0．1个NTU左右：对CODMa的去除率达到了77．30％～82．80％，出水CODMn在0，4～0，46mg／L间；整个装置占地面积省，约l.28m^2．

The technique of pretreatment ＋ UF is adopted by the integrative water purification equipment in the water treatment of Changiiang River. The outcome is large; it is 15.00-16.40 L/min when the inflow is 16.83-17.67 L/min, which accounts for 89.0%-93.0% of the inflow. The water quality is well; the removal efficiency of the turbidity and the organic matter are very well. The turbidity of the outflow is under 0.1 NTU, and the removal efficiency of it is beyond 99 %. The CODMn of the outflow is between 0.4 and 0.46 rag/L, and the removal efficiency of it reaches to 77.30% - 82.80%. The equipment occupies small area, which takes up about 1.28 m^2 smaller.
