Problems solved by technology

However, in the traditional treatment process for high-concentration organic wastewater, the anaerobic reactor and the aerobic reactor are usually constructed separately. The civil construction is complicated and the floor area is large. It is uneconomical and inconvenient to manage for small and medium water volumes.
[0003] Through scientific and technological novelty search, there is no report on the integrated biofilm equipment for the treatment of high-concentration organic wastewater at home and abroad.

Embodiment Construction

[0022] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0023] Referring to Figures 1, 2, and 3, the processing equipment is composed of a pool body 1, a water inlet pipe 2, and a drain pipe 3. The body of the pool is divided into two reaction zones: the middle is an anaerobic submerged biofilm reaction zone 4, and the periphery is an aerobic submerged biofilm reaction zone 5, using a square pool body. Semi-soft fiber packing 8 is arranged in each reaction zone, and drainage zones 6 and 7 are set on the four corners of each reaction zone. The water inlet pipe 2 of the equipment directly enters the anaerobic submerged biofilm reaction zone 4 from the upper part, and the drainage area 6 of the anaerobic submerged biofilm reaction zone is connected to the peripheral aerobic submerged biofilm through the drainage pipe 12 with a gate valve Reaction zone 5. The aerobic submerged biofilm reaction zone 5 is also provided wit...

Abstract

The invention discloses a sequencing batch type combined biofilm integrated apparatus for treating high concentration organic wastewater, wherein a tank body is provided with two submerged biological film reaction zones, the center of the tank body is an anaerobic submerged biological film reaction zone, the periphery of the tank body is an aerobic submerged biological film reaction zone, the anaerobic submerged biological film reaction zone is closed, the two reaction zones are provided with half-soft fiber fillings internally and a a underwater propeller on the bottom, the packing of the anaerobic submerged biological film reaction zone is provided with a underwater aeration apparatus on the bottom.

Description

Technical field: [0001] The invention belongs to the technical fields of sewage treatment and environmental protection, and in particular relates to a sequence batch combined biofilm integrated equipment for treating high-concentration organic wastewater. Background technique: [0002] Both submerged biofilm and sequencing batch reactor are existing technologies used in wastewater treatment, and they have their own advantages. Compared with the activated sludge method, the submerged biofilm has the advantages of large biomass, suitable for microorganisms with a long growth generation cycle, strong treatment capacity, good treatment effect, impact load resistance, and little influence by temperature; while the sequencing batch reactor ( SBR) conforms to the development trend of simplicity, high efficiency, energy saving, flexibility and multi-function required by contemporary sewage treatment due to its flow pattern and spatial pushing flow characteristics of organic matter d...
