[0002] Chemical wastewater is wastewater discharged from chemical production, such as process wastewater, cooling water, exhaust gas washing water, equipment and site washing water. Pure water changes its original physical or chemical properties after use and becomes wastewater containing different types of impurities. Chemical wastewater is wastewater discharged from chemical production, such as process wastewater, cooling water, exhaust gas washing water, equipment and site washing water. If these wastewaters are discharged without treatment, they will cause different properties and different degrees of pollution in the water body, thereby endangering human health and affecting industrial and agricultural production.
