Problems solved by technology

At present, measures to improve and stabilize the biochemical treatment of sewage and wastewater mainly adopt the one-time setting of immobilized packing and mobile packing, and realize the method of increasing the contact area of ​​epiphytic microorganisms (referred to as film hanging). This measure is effective, but there are still the following The problem has not been solved: 1. It takes a long time to successfully grow the membrane through the natural domestication of the indigenous bacteria in sewage and wastewater, even exceeding the tolerable time, and the efficiency of the dominant bacterial group formed is not high; 2. It has been stably operated through inoculation The mother liquor of the engineering sewage and wastewater system is used for fast film formation, but the film formation efficiency is still not ideal, and it may introduce harmful biological communities outside the territory; 3. By adding commercial engineering strains to the water body, the film formation efficiency is improved, because Bacteria are dispersed in the whole flowing water body in liquid or powder, which will be continuously diluted and flowed away, and it still takes time to attach to the filler for the second time to successfully form the film, and the efficiency is not fast enough, which restricts the biochemical treatment of sewage and wastewater Onset time, cycle time, efficiency and stability
The more serious situation is: the purity and concentration of the active bacteria in the bacterial liquid or powder purchased in batches is very low, which cannot meet the requirements for use, and sometimes it has even been deactivated and deteriorated, causing more problems

Embodiment 1

[0063] see figure 2 , figure 2 The schematic diagram of wastewater treatment and recycling of freshwater aquaculture ponds is introduced; the wastewater from aquaculture ponds first passes through the physical filtration equipment microfiltration machine to filter and remove solid particles in the water, and then enters the biochemical pond, and the film-hanging filler is directly added to the biochemical pond , the biochemical pool carries out conventional stirring, decarburization, and oxygenation processes, and the dominant bacteria on the film-coated fillers biodegrade, absorb and assimilate the harmful substances dissolved in water to farmed animals, making them harmless and bait , or mineralize into carbon dioxide, water, or become inert gas to escape the water body, and then return to the breeding pond through constant temperature, acid-base adjustment, disinfection, oxygenation and other processes for recycling.

Embodiment 2

[0068] see Figure 4 , Figure 4 Introduces the schematic diagram of wastewater treatment and discharge or reclaimed water reuse; sewage and wastewater enter the biochemical pool group after the pre-treatment process, and the film-coated filler is directly added to the biochemical pool, and the biochemical pool undergoes conventional stirring and decarbonization , Oxygenation process, the dominant bacteria on the film-hanging filler biodegrade, absorb and assimilate the harmful substances dissolved in water to farmed animals, making them harmless, baitized, or mineralized into carbon dioxide, water, or It becomes an inert gas and escapes from the water body, and then after disinfection and other post-processing processes, it is discharged up to the standard, or the reclaimed water is reused.

Embodiment 3

[0071] see Figure 5 , Figure 5 Introduced the schematic diagram of fish and vegetable symbiotic water treatment; the wastewater from the aquatic animal breeding pool group enters the biochemical pool group, and the film-coated filler is directly added to the biochemical pool. The dominant bacteria on the membrane filler biodegrade, absorb and assimilate the organic matter and ammonia nitrogen in the water, etc., making them harmless, especially nitrifying ammonia nitrogen into nitrate nitrogen that is most suitable for plants to absorb, and further disinfecting the plants Cultivation, the water quality after the three-dimensional plant cultivation is returned to the aquatic animal breeding pool group, so as to realize the double harvest of fish and vegetables and recycling.

Abstract

The invention provides a method for biofilm culturing of a filler via a fermentation reactor and transferring the filler to a biochemical pool. The method comprises the following steps: putting a soaked and flushed filler and clean water into a fermentation reactor together, carrying out disinfection and inactivation treatment, adding a culture medium matched with a fermentation strain into the fermentation reactor, carrying out premixing and homogenizing treatment, adding the fermentation strain into the fermentation reactor, and continuing to operate the fermentation reactor until a biofilmgrows on the surface of the filler; putting the biofilm-cultured filler into a working biochemical pool; detecting whether the water quality in the biochemical pool reaches a standard or not at set intervals; and, fishing out the ineffective filler in the working biochemical pool, cleaning the filler, and putting the filler into the fermentation reactor in the step S3 again for fermentation again.According to the invention, since the filler and mother liquor which have successfully undergone biofilm culturing are directly fed into the biochemical pool to serve as a working filler and workingflora of the biochemical pool, so the biochemical pool directly enters an ideal working state, the long biofilm culturing time of the biochemical pool is saved, and a biochemical process is kept stable and continuously improved.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a method for forming a film on a filler through a fermentation reactor and transferring it to a biochemical pool. Background technique [0002] The biochemical treatment method in wastewater treatment is referred to as biological treatment method or biochemical method. The treatment process of this method is to mix and contact the sewage and wastewater with microorganisms, and use the physical and chemical reactions, material and energy transfer during the growth and reproduction of microorganisms to decompose organic matter and harmful inorganic substances (such as ammonia nitrogen) in sewage and wastewater, and convert them into harmless Substances such as carbon dioxide, water, nitrogen, etc., may be decomposed into methane and other collectible substances to be discharged into water bodies, or assimilated into microorganisms themselves and discharged into water bodies thr...
