Embodiment 1

[0028] combined with figure 1 As shown, the present embodiment provides a microbial expansion cultivation system for sewage treatment, including expansion cultivation box 1, water inlet pipeline 2, expansion cultivation tank 3, water outlet pipeline 4, liquid level monitoring device and control device (Fig. not shown).

[0029]The expansion box 1 of this embodiment is a box structure with an open top and a hollow interior. The bottom wall and the side wall of the expansion box 1 are provided with a plurality of through holes 101, and the expansion box 1 is provided with microorganisms. Carrier 102, the material of the microbial carrier is preferably ceramsite or polyurethane, and its performance is stable. The microbial carrier 102 in this embodiment is immobilized with high-efficiency microbial flora capable of decomposing organic matter and ammonia nitrogen through biochemical techniques such as embedding and adsorption. The biochemical technologies such as embedding and ad...

Embodiment 2

[0037] On the basis of the above examples, the applicant found during the experiment that when treating black and odorous rivers, eutrophic lakes and waste water with zero sludge, due to the poor fluidity of the mixture of sewage and sludge, not only sewage and sludge It is not easy to enter the expansion tank through the expansion box, and the sewage and sludge cannot be evenly dispersed into the expansion tank, so the expansion effect of the microbial carrier set in each area of ​​the expansion tank is uneven, and even some sludge has not passed through the microorganisms. After treatment, it is discharged into the sewage water source, which greatly reduces the expansion efficiency and sewage sludge treatment efficiency. Therefore, the applicant has made a lot of creative improvements to the entire expansion system:

[0038] combined with figure 2 As shown, in this embodiment, a filtering device (not shown in the figure) is first provided at the other end of the water inlet...

Abstract

The invention provides a microbial expanding culture system. The system comprises an expanding culture box, a water inlet pipeline, an expanding culture pond, a water outlet pipeline, a liquid level detecting device and a control device; the expanding culture tank is provided with a plurality of through holes, and a microbial carrier is arranged in the expanding culture box; the water inlet pipeline is respectively communicated with a sewage source and the expanding culture box; and the microbial carrier is placed in the expanding culture pond, the expanding culture box is placed in the expanding culture pond, and the expanding culture pond is provided with a water outlet. The expanding culture box in the expanding culture pond to realize multistage culture and initially filter out impurities in sewage, the expanding culture box is communicated with the sewage inlet pipeline, the expanding culture pond is connected with the sewage outlet pipeline, pollutants in polluted water are utilized in situ as a nutrient source to continuously and stably culture seed strains in an expanding manner in order to continuously produce a microbial stock solution, the microbial stock solution afterthe cultivation is afresh added into the sewage source to further purify the sewage, and the seed strains are added at one time without repeatedly adding.

Description

technical field [0001] The invention relates to the technical field of microorganism cultivation, in particular to a microorganism expansion cultivation system applicable to sewage treatment. Background technique [0002] At present, the seriously polluted river water has adverse effects on the river water environment and the production and life of the towns along the coast, posing a potential threat, and the sewage contains high nitrogen and phosphorus content, which will cause a lot of waste of resources if not used. How to purify polluted river and lake water Turning it into daily production and living water and solving people's water problem is a problem that people urgently need to solve at present. [0003] At present, the known river water purification methods are physical and chemical methods, physical mechanical methods and biological methods. Physical and chemical methods are temporary methods that cure the symptoms but not the root cause. The physical and mechanic...
