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] The present invention will be further described below in conjunction with the drawings and embodiments:

[0023] See figure 1 , 2 , 3. This treatment equipment is composed of a pool body 1, an inlet pipe 2, and a drain pipe 3. The tank body is divided into two reaction zones: the middle is the anaerobic submerged biofilm reaction zone 4, and the periphery is the aerobic submerged biofilm reaction zone 5, using a square tank body. Semi-soft fiber filler 8 is arranged in each reaction zone, and drainage zones 6, 7 are arranged 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. The drainage area 6 of the anaerobic submerged biofilm reaction zone is connected to the peripheral aerobic submerged biofilm through a drain pipe 12 with a gate valve. Reaction zone 5. The aerobic submerged biofilm reaction zone 5 is also provided with a drain pipe 3 with a gate valve a...

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 field of sewage treatment and environmental protection, and specifically relates to a sequential batch type combined biofilm integrated device for processing high-concentration organic wastewater. Background technique: [0002] Both the submerged biofilm and the 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 growth of microorganisms with a long generation cycle, strong processing capacity, good processing effect, impact load resistance, and less influence by temperature; while the sequencing batch reactor ( SBR) due to its flow pattern and organic matter degradation spatial push flow characteristics, it conforms to the development trend of simplicity, efficiency, energy saving, flexibility and multi-function required by contemporary sew...
