Embodiment Construction

[0029] Examples see figure 1 , figure 2 As shown, this vertical oxygen-enriched vortex domestic sewage treatment device includes a pit pond 1, the inner water surface height of the pit pond 1 is less than 6 meters, there is a water inlet pipe 2 on one side of the pit pond, and a water outlet pipe 3 on the other side. The pond is divided into anaerobic zone 4, aerobic zone 5, sedimentation zone 6 and stable zone 7 with three soft partitions 18 from the water inlet side to the water outlet side, and one side of each soft partition 18 is connected to the pit pond. One side wall is closed and connected, and there is a water flow channel 21 between the other side and the other side wall of the pit. The adjacent soft partitions 18 are not connected to the same side wall of the pit. Three soft partitions 18 are interlaced with each other. The water flow is S-shaped, the bottom of each soft partition 18 is fixed to the bottom of the pond 1, and the top is connected with a floating o...

Abstract

The invention relates to vertical oxygen-enriched vortex domestic sewage device and method. The device comprises a pond, wherein one side of the pond is provided with a water inlet pipe and the other side is provided with a water outlet pipe, the inner part of the pond is sequentially divided into an anaerobic zone, an aerobic zone, a settling zone and a stabilizing zone by three flexible partitions from the water inlet pipe to the water outlet pipe, three flexible partitions are staggered, water flow channels are reserved among the flexible baffles and the side walls of the ponds, aeration nozzles are respectively arramged at the bottoms of the aerobic zone and the stabilizing zone and are connected with a fan through aeration pipes, the aeration pipes are connected with aeration valves,the bottom of the settling zone is connected with a residual sludge discharging pipe which is connected with a residual sludge discharging valve, one side of the residual sludge discharging pipe is connected with a sludge return pipe which is communicated with the aerobic zone and the water inlet pipe through branch pipes, and the branch pipes are respectively connected with a sludge return valve. The invention can achieve the purpose of removing pollutants of organic matters, nitrogen, phosphorus and the like in sewage so as to reach the sewage emission standard, and is suitable for a novel sewage biochemical treatment device in countries and towns.

Description

technical field [0001] The patent of the present invention relates to a sewage biochemical treatment device and method. Background technique [0002] Sewage treatment can be roughly divided into physical treatment, chemical treatment and biochemical treatment according to the mechanism of action. Physical treatment is mainly used to remove suspended solids and other particulate matter in sewage, and the main methods involve filtration, precipitation, etc.; chemical treatment is mainly used to remove colloidal substances, insoluble organic matter and dissolved metal ions in sewage, and the main methods and methods It involves flocculation, chemical precipitation, etc.; biochemical treatment is mainly used to remove dissolved organic matter and nitrogenous substances in sewage. The existing main treatment processes include aeration tank, biological turntable, biological contact oxidation, etc. [0003] The existing sewage biochemical treatment process mainly uses reinforced c...
