Industrial wastewater grading comprehensive utilization method
The invention relates to the technical field of waste water of a thermal generator set, in particular to a graded comprehensive utilization method of industrial waste water, which is characterized in that waste water discharged by a low-temperature rack in a steam-water sampling module and water discharged by fine treatment sampling and testing are clean in water quality, are not polluted and are graded into zero-grade waste water; wastewater discharged by a unit drainage tank during normal operation of a unit is low-salt wastewater and is classified into first-stage wastewater; the pH value of the chemical system wastewater is slightly weakly acidic, the salt content is relatively high, the chloride ion content is relatively low, and the chemical system wastewater is classified into secondary wastewater; the refined treatment regenerated wastewater, wastewater of a unit drainage tank in the unit start-stop stage and wastewater of an ammonia area are acid-base-containing high-salinity wastewater and are classified into three-stage wastewater. According to the method, industrial wastewater sources are subjected to graded management and graded utilization treatment, so that the utilization of water resources is finer and more reasonable, the purpose of deep water saving is achieved, and the situation that secondary pollution is generated after multiple kinds of wastewater are mixed, and consequently industrial wastewater treatment and recycling are not thorough is avoided.
本发明涉及火力发电机组废水技术领域，尤其涉及一种工业废水分级综合利用方法，汽水取样模块中的低温架排放废水和精处理取样化验排水的水质干净，未经任何污染，分级为零级废水；机组排水槽在机组正常运行期间排放的废水为低盐类废水，分级为一级废水；化学系统废水的pH值为轻微弱酸性，且含盐量较高，氯离子含量较少，分级为二级废水；精处理再生废水、机组排水槽在机组启停阶段的废水、氨区废水为含酸碱高盐废水，分级为三级废水。该方法通过对工业废水来源进行分级管理分级利用处理，对于水资源的利用更加精细化与合理化，达到深度节水的目的，还避免了多种废水混合后产生二次污染，导致工业废水处理回用不彻底的情况。
