Problems solved by technology

[0003] Conventional sewage treatment methods are mainly biochemical methods, namely activated sludge method and biofilm method. Among them, there are many kinds of activated sludge denitrification and phosphorus removal processes. At present, A / A / O process and UCT process are more commonly used. , improved Carrousel process, AB process, SBR process, CAST process, Unitank process, MSBR process, etc. Compared with the ACCP process of the present invention, the above-mentioned process has a long process flow and many structures. Sand tanks, primary sedimentation tanks, aeration tanks or biofilm tanks, secondary sedimentation tanks or hydraulic circulation clarification tanks, contact disinfection tanks, even advanced treatment coagulation sedimentation tanks, various forms of filters or ultrafiltration membrane tanks, etc. Large land area, large construction investment, high energy consumption, high operating costs, complex operation and management, and large sludge output. These processes have advantages in large and medium-scale sewage treatment, but are not suitable for small and medium-scale sewage treatment projects.

Abstract

The invention discloses a sewage biochemical treatment integrated device, system and process method. The sewage biochemical treatment integrated device comprises a pond body (17), wherein an incline guide baffle plate (6) is arranged in the pond body (17), one side of the incline guide baffle plate (6) is provided with an aeration assembly (12) and a vertical gas stripping and reflowing assembly (4), an outer reflowing sludge discharging bucket / trough (13) is arranged between the aeration assembly (12) and the incline guide baffle plate (6), the other side of the incline guide baffle plate (6) is provided with a settling assembly (10) and an incline guide plate / tube (9) parallel with the incline guide baffle plate (6), a chemical spraying perforated pipe (8) is arranged above a water feeding hole of the incline guide plate / tube (9), a settled sludge discharging bucket / trough (14) is arranged below the settling assembly (10), and a movable shielding plate (16) is arranged above the settling assembly (10). The sewage biochemical treatment integrated device has the advantages of small occupation area, low energy consumption, engineering investment reduction, low operation cost and easiness in operation and management because of the combination of gas stripping and reflowing circulating denitrification and suspension cleared sediment dephosphorization.
