Abstract

The invention discloses an anaerobic reactor and an organic printing-dyeing wastewater treatment system comprising the same. The anaerobic reactor comprises a tower, a water distribution area, a high-load anaerobic treatment area, a primary triphase separation area, an anaerobic bio-membrane treatment area, a secondary triphase separation area and a gas-water separation area are sequentially arranged inside the tower from bottom to top. The anaerobic reactor is simple in structure, low in input cost, convenient to operate, capable of respectively collecting and treating according to water quality difference of wastewater generated by different processes, highly targeted, excellent in treatment effect and capable of finally making outgoing water to meet discharging standard requirements.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, and in particular relates to an anaerobic reactor and an organic printing and dyeing wastewater treatment system containing the reactor. Background technique [0002] Printing and dyeing enterprises are one of the major pollutant dischargers in various industries of the national economy, and their annual discharge ranks among the top five in the wastewater discharge of various industrial enterprises in the country, and there is a trend of increasing year by year. Printing and dyeing wastewater is mainly composed of desizing wastewater, boiling wastewater, bleaching wastewater, mercerizing wastewater, dyeing wastewater, auxiliaries, slurry, acid and alkali, etc. It has the characteristics of high concentration, deep color, complex components, and poor biochemical properties. If it is directly discharged without treatment, it will cause water pollution and may directly or indirect...
