摘要：采用索凝法对泡莱废水进行了试验，分别考察了絮凝剂的种类、助凝剂的种类、PAM分子量、投加方式、PH值、温度、搅择转速等条件对泡莱废水絮凝处理效果的影响，为泡莱废水的后期生化处理提供了帮助的同时也可为泡菜厂实际索凝处理提供一定的参考。在含大量NaCI的泡莱废水中，利用PAM网捕、架桥功能完善了PAC单独作用下絮体细小松散的缺陷，改善了素凝和沉降性能。研究结果表明：PAC用量150mg/L,PAM用量25mg/L.pH6，温度30C，250r/min快搅 2min，90r/min慢搅2min，静置30min后泡莱废水COD、浊度去除率分别达到了37.7%、 96.7%。

Abstract: With the flocculation test carried out on the pickled cabbage water, the type of flocculant and coagulant+ molecular mass of PAM, sequence of addition, pH, temperature, and stirring speed are investigated on the effect of flocculation treatment of pickle waste water, which makes the next stages of biochemical treatment more easily and provides a reference for the selection of the flocculation parameters of kimchi factory. In the pickled cabbage wastewater which contains a large number of NaCl, the flocculation and sedimentation performance are improved by the addition of PAM because of its bridging functions. Under the condition of PAC dosage of 150 mg/L, PAM dosage of 25 mg/L, pH6, at the temperature of 30 C, by 2 minutes of a magnetic stirrer stirring (250 rpm/min) and a slow stirring (90 rpm/min), static
30min, the best result is obtained. The removal rate of COD and turbidity reaches 37. 7%, 96. 7%. Keywords:pickle wastewater;flocculant; coagulant;removal rate
