摘　　要：采用硅藻土做助滤剂，通过预涂和主体吸附、过滤的方法处理萘酚类染料工业废水，回收其中溶解的Na2SO3。研究结果表明：采用此过滤方法获得的晶体Na2SO3，其回收率和相对含量都优于筛网过滤法。并应用Carman方程式计算出过滤定量液体所使用的最佳助滤剂用量及对应压力。By means of Na2SO3 can be recycled from Diatomite as filter, pretreatment coat, main part adsorption and filtration, naphthols dye industrial waste water. Results showed that this method can bring better yield and relative contents of crystal Na2SO3 than other filtrating methods. Besides, using Carman equation, optimum filtrating dosage needed in filtrating quantitative liquor and the comparative pressure were also calculated in this way.
