The invention discloses a seasonal high-turbidity raw water treatment process. Raw water enters a settling pond for sedimentation after entering a pre-sedimentation, concentration and reuse pond for pre-sedimentation; after the water obtained through sedimentation enters a filter pond to be filtered and enters a clean water pond to be regulated and stored, the water is pumped into a municipal pipe network after being pressurized through a secondary pump house; sludge discharged out of the pre-sedimentation, concentration and reuse pond is received into a balance pond to be stored; the discharge sludge enters a dewater room to be dewatered, and dry sludge obtained through dewatering is transported outwards to be processed, and filter liquor is drained into a concentration mass-energy conversion pond. The process can adapt to different raw water situations and can meet different running requirements; the sludge discharge and water treatment process and the dewatering process are combined together; meanwhile, the process adapts to the seasonal high-turbidity and general low-turbidity working condition, secondary processing is conducted on concentration pond supernatant and dewatering filter liquor which are prone to exceeding the emission standard in the industrial wastewater concentration and dewatering process through the concentration mass-energy conversion pond, the occupied area is saved by highly using the processing capacity of buildings, and the effects of discharging water, obtained in the water purification process, in an up-to-standard mode and converting organic matter in industrial wastewater into biological energy sources to be further recycled are achieved.
