[0002] Coking wastewater is a typical toxic and refractory organic wastewater. Coking wastewater mainly comes from the primary cooling of coke oven gas, production water and steam condensate wastewater in the coking production process. Characteristics: The pollutant concentration in coking wastewater is high and difficult to degrade. Due to the presence of nitrogen in coking wastewater, the nitrogen source required for biological purification is excessive, which brings great difficulties to meeting the treatment standards. Polycyclic aromatic hydrocarbons in coking wastewater are not only difficult to degrade, but also usually strong carcinogens, which cause serious pollution to the environment and directly threaten human health.

[0003] During the treatment of coking wastewater, the pretreated coking wastewater enters the flocculation tank. Under the action of adding flocculants, suspended solids, colloidal substances and some dissolved organic matters in the wastewater aggregate into flocs, further accelerating the sedimentation speed. At present, during the purification and filtration of coking wastewater, a barrel filter is mostly used. After long-term use, impurities are likely to accumulate on the inner barrel, and manual shutdown is required for cleaning, which affects the filtration use and cannot achieve continuous filtration treatment.
