Industrial sewage treatment method

The invention discloses an industrial sewage treatment method which comprises the following steps: adding industrial sewage containing caustic soda of which the concentration is 1-5g/L into a boiler;then, concentrating the industrial sewage in the boiler until the water concentration of the industrial sewage is reduced to 10-20%; and finally, discharging the concentrated industrial sewage out ofthe boiler so as to recycle the sewage. The invention provides a treatment method for concentrating the industrial sewage by using the boiler, and the problems that a traditional boiler is poor in corrosion resistance and the inner side wall of the boiler easily generates impurities such as scale can be solved through a coating at the same time. 本发明公开了种工业污水处理方法，将含有烧碱浓度为1～5克/升的工业污水加入到锅炉内，然后对锅炉内的工业污水进行浓缩处理直至工业污水的含水浓度降到10～20%，最后将浓缩处理后工业污水排出锅炉外进行回收处理；本发明的有益效果是：提供了种通过使用锅炉浓缩处理工业污水的处理方法，同时也通过涂层解决传统锅炉耐腐蚀性差，且锅炉的内侧壁容易产生水锈等杂质的问题。
