The main process of metal wire drawing wastewater treatment is removing impurity and demulsification. This article took Saint Electrician production workshop waste wiredrawing fluid (in which, COD content is 11 233 mg/L, pH value is 8.4 and the content of wire drawing oil is 4%) as research object, used chemical demulsification method and through laboratory experiment, adopted electrolyte and coagulant separately to deal with the wastewater.

金属拉丝废水的处理工艺主要过程是去除杂质和破乳，以赛特电工生产车间的废拉丝液为研究对象（COD含量为11 233 mg/L，pH值8.4，拉丝油含量4%），选用化学破乳法，通过实验室实验，分别采用电解质和混凝剂处理废液。

The experiment results shown that: 1 the smaller the pH value, the smaller the use amount of alkaline metal and the alkali earth metal electrolyte demulsifier, when the pH value was 3, the waste fluid could be demulsified no any demulsifier and the use amount of the demulsifier did not increase remarkably along with the wiredrawing fluid concentration increased. 2 Using polymeric ferric sulfate as coagulant demulsifying, when the pH value was 8.4, the best adding amount was 40 mL per liter wastewater and the best precipitation time was 4 hours. Then the COD concentration was 480 mg/L, reaching the water quality requirements to enter the sewage treatment plant.

pH值越小，碱金属和碱土金属电解质破乳剂的用量越小，pH值为3时，无须加入任何破乳剂即可破乳；破乳剂用量并不随拉丝液浓度的增大而显著增加。2）用混凝剂聚合硫酸铁破乳，在pH值8.4时，最佳投加量为40 mL/L，最佳沉淀时间4 h，处理后上清液COD浓度为480 mg/L，能满足进入污水处理厂水质要求。

The effects of magnetic seed, aluminum sulphate and pH value on phosphorus adsorption, precipitation and coagulation were surveyed. The results made it clear that Al ion as precipitant and coagulant was the main effect factor on P removal; as adsorbent magnetic seed had little effect on P removal, but made the phosphate precipitate sink faster; pH value had effect on both precipitation and adsorption.

研究了磁种、硫酸铝、pH值等对磷的吸附、沉淀、凝聚的影响，结果表明：铝离子的沉淀作用是除磷的主要原因；磁种的吸附作用对除磷的贡献较小，但使磷酸盐沉淀物的沉降性能大大提高；pH值既影响沉淀作用，也影响吸附作用。
