Embodiment 1

[0064] The effluent quality of a certain industrial wastewater cannot meet the requirements of Class 1 (A). It is planned to use the biofilm method to upgrade the original aerobic tank.

[0065] The specific implementation process of this example is:

[0066] 1) Sampling the target film-coated mud-water mixture and homogenize with a homogenizer; the number of homogenization is 15 times.

[0067] 2) Filter the fully homogenized mud-water mixture with a 10 micron filter membrane and take the filtrate;

[0068] 3) Divide the filtrate into two parts, one part of the filtrate is labeled as filtrate A; the other part of the filtrate is filtered through another 0.22 micron filter membrane and then the filtrate is taken, labeled as filtrate B, which is the reference solution of filtrate A;

[0069] 4) Fix the No. 1 diaphragm 3 in the film formation monitoring cabin 4;

[0070] 5) The combination of fast matching wastewater and filler film-hanging device is completed;

[0071] 6) Feed the filtrate...

Embodiment 3

[0090] The effluent quality of a certain industrial wastewater cannot meet the requirements of Class 1 (A). It is planned to use the biofilm method to upgrade the original aerobic tank.

[0091] The specific implementation process of this example is:

[0092] 1) Sampling the target film-coated mud-water mixture and homogenize with a homogenizer; the number of homogenization is 12 times.

[0093] 2) Filter the fully homogenized mud-water mixture with a 9 micron filter membrane and take the filtrate;

[0094] 3) Divide the filtrate into two parts, one part of the filtrate is labeled as filtrate A; the other part of the filtrate is filtered through another layer of 0.3 micron filter membrane and then the filtrate is taken, labeled as filtrate B, which is the reference solution of filtrate A;

[0095] 4) Fix the No. 1 diaphragm 3 in the film formation monitoring cabin 4;

Abstract

The invention discloses a device and device for rapidly matching wastewater and a packing for biofilm formation and belongs to the technical field of biological membrane sewage treatment. The device for rapidly matching the wastewater and the packing for biofilm formation comprises a cabin fixing base, a biofilm formation monitoring cabin, ultrasonic probe installing cabins, an ultrasonic wave generator, an oscilloscope and a control system, wherein the ultrasonic probe installing cabins are installed above and below the biofilm formation monitoring cabin respectively, ultrasonic sensing probes are arranged in the ultrasonic probe installing cabins, and the upper portion of the cabin fixing base is connected with the ultrasonic probe installing cabin below the biofilm formation monitoring cabin. The two ultrasonic sensing probes are connected with the ultrasonic wave generator, the oscilloscope and the control system in sequence. The packing with highest biofilm formation speed serves as a target packing through sludge pretreatment-membrane arrangement-ultrasonic online biofilm formation monitoring process, namely the matching process is completed, effective biofilm formation can be achieved to the most degree, the whole biofilm formation time can be shortened, and the rick taken by adopting a packing technology is minimized.

Description

Technical field [0001] The invention belongs to the technical field of biological membrane method sewage treatment, and more specifically, relates to a device and method for quickly matching waste water and filler film. Background technique [0002] In the secondary biochemical treatment system of sewage treatment, the activated sludge method and the biofilm method dominate. The biofilm method has good water quantity and water quality adaptability, removal of organic matter, nitrogen and phosphorus removal, and heavy metal removal. The advantages of cost saving and other advantages have been widely concerned and applied. Biofilms are mainly composed of microbial cells and their product films that undergo growth, maturation and aging cycles. Biofilm carriers generally include soft fillers, composite fillers and suspended fillers. Soft fillers and composite fillers are the first to be widely used in processing textiles due to their light weight, large specific surface area, varia...
