Problems solved by technology

On the one hand, untreated domestic sewage flows into surface water bodies such as low-lying rivers, lakes and ponds, seriously polluting various water sources; on the other hand, domestic sewage is also the source of disease transmission, which is likely to cause infectious diseases, Occurrence and prevalence of endemic and zoonotic diseases
At present, the penetration rate of tap water in rural areas across the country is only about 34%, and more than 300 million farmers still have drinking water safety problems

Embodiment 1

[0026] Embodiment 1: Referring to the accompanying drawings, the biochemical filtration integrated device for advanced treatment of rural sewage: it is provided with a sewage regulating pool 1, a biochemical pool 4, a biochemical filtering pool 8, an outlet pool 14 and an equipment room 13, the sewage regulating pool and the biochemical pool There is a sewage pretreatment pool 3 between them, and the sewage regulating pool is provided with an outlet pipe and an outlet pump 2 to communicate with the upper part of the sewage pretreatment pool, and the bottom of the sewage pretreatment pool is provided with an outlet pipe to communicate with the bottom of the biochemical pool; Flow into the overflow port of the biochemical filter tank; the bottom of the biochemical tank is provided with a mud discharge pump 5 and a mud discharge pipe; 7. A filter membrane 9 is provided in the biochemical filter tank, and a backwash pump 11 is provided; the biological filter tank communicates with ...

Embodiment 2

[0027] Embodiment 2: The operation method of the biochemical filtration integrated device for the advanced treatment of rural sewage, taking the actual domestic sewage of a sewage treatment plant in Beijing as the test object: pH=6.5~7.8, COD=260~370mg / L, TN=50~65mg / L, TP=3~5mg / L. The selected biochemical pool has an effective volume of 14m 3 , biochemical filter effective volume 4m 3 . The hourly water flow rate of the water inlet pump is: 4m 3 / h, the running method proceeds as follows:

[0028] (1) Water intake: The sewage regulating tank collects rural sewage. When the sewage in the sewage regulating tank reaches the start-up water level, the water inlet pump is turned on, and the water inlet pump sends the sewage from the sewage regulating tank to the sewage pretreatment tank. The sewage in the sewage pretreatment tank After pretreatment by the dirt filter device, it enters the biochemical pool from the bottom, and enters the water for 1 hour. After the water level i...

Abstract

The invention discloses a rural sewage advanced treatment and biochemical filtration integration device and a running method thereof. The device is provided with a sewage equalizing tank, a sewage pretreatment tank, a biochemical pool, a biochemical filter tank, a discharged water tank and an equipment room, the sewage equalizing tank is provided with a water discharge pump and is connected with the sewage pretreatment tank and the biochemical tank; the biochemical tank is provided with an overflow hole, and is connected with the biochemical filter tank; the bottom of the biochemical tank is provided with a sludge discharge pump, the bottom of each of the biochemical tank and the biochemical filter tank is provided with an aerating pipeline connected with a blower and an aerating head, and a filter membrane and a back flush pump are arranged in the biochemical filter tank; and the device is also provided with a control board connected with the above pumps and the fan. The running method comprises the steps of water feeding, aeration of the biochemical tank, precipitation of the biochemical tank, feeding of water to the biochemical tank and aeration of the filter tank, aeration of the biochemical tank, precipitation of the biochemical tank, sludge discharge of the biochemical tank, and back flushing of the biochemical filter tank. The device is suitable for rural sewage treatment, has the advantages of simple operation, unmanned operation and low cost, and realizes advanced nitrogen and phosphorus removal of the rural sewage.

Description

technical field [0001] The invention relates to a sewage treatment technology, specifically an integrated biological treatment device and process for rural sewage, especially an integrated device and operation method capable of realizing deep denitrification and phosphorus removal of sewage, which is suitable for rural sewage treatment and urban unconnected Point source small flow sewage treatment into the pipe network. Background technique [0002] The rural areas of the country produce more than 8 billion tons of domestic sewage every year, and 96% of the villages do not have drainage channels and sewage treatment systems. The random discharge of domestic sewage has seriously polluted the ecological environment in rural areas, directly threatening the health of farmers and the economic development of rural areas. On the one hand, untreated domestic sewage flows into surface water bodies such as low-lying rivers, lakes and ponds, seriously polluting various water sources; ...
