从武夷山屠宰厂和垃圾渗滤液中筛选出絮凝活性超过90％菌种2株，分别为D-3和F-4。在不同的温度、pH和絮凝剂投加量条件下，研究D-3和F-4絮凝剂对屠宰厂废水处理效果。实验结果表明：pH值为7，温度为11～23℃，絮凝剂投加量为2mL时，对屠宰厂废水的处理效果最佳，化学需氧量（COD）去除率和脱色率分别达到了75．4％和72．3％（F-4为絮凝剂）。
從武夷山屠宰廠和垃圾滲濾液中篩選齣絮凝活性超過90％菌種2株，分彆為D-3和F-4。在不同的溫度、pH和絮凝劑投加量條件下，研究D-3和F-4絮凝劑對屠宰廠廢水處理效果。實驗結果錶明：pH值為7，溫度為11～23℃，絮凝劑投加量為2mL時，對屠宰廠廢水的處理效果最佳，化學需氧量（COD）去除率和脫色率分彆達到瞭75．4％和72．3％（F-4為絮凝劑）。

In this paper, D -3 and F- 4 flocculant- producing microorganism with floccula- ting activity more than 90% were screened from food factory sewage of Wuyishan and landfill leachate treatment. Treatment effects of butchery wastewater were studied by D - 3 and F - 4 as a microbial flocculant, on the condition of different temperature, pH value and flocculant dosage. The results showed that the optimal operation conditions were obtained as follows ： pH 7.0, temperature 11 - 23 ℃ and flocculant dosage 2 mL. Removal rate of COD and decoloring rate of butchery wastewater by F - 4 were 75.4% and 72.3%, respectively.
