Comprehensive wastewater treatment process

The invention discloses a comprehensive wastewater treatment process which comprises the following steps: firstly, carrying out uniform and homogeneous regulation on comprehensive wastewater through a comprehensive regulation tank, carrying out oxidation through a Fenton oxidation tank, introducing the wastewater into a coagulative precipitation tank for precipitation after oxidation, carrying out mud-water separation after precipitation, introducing effluent into an intermediate water tank, pumping the effluent into a UASB (Upflow Anaerobic Sludge Blanket) tank, and then introducing the effluent into a tank A for anaerobic reaction; the sludge enters an O tank for oxygen consumption biochemical reaction and then enters a secondary sedimentation tank for sedimentation, and the sludge is pumped into a sludge tank and is dehydrated and formed by a plate-and-frame filter press. Pollutants in water can be effectively removed, sewage treatment is thorough, the treatment cost is low, toxicity and pollution are avoi
