Problems solved by technology

However, the treatment volume is large, the content is low, and the enrichment of ammonia nitrogen and organic phosphorus due to non-point source pollution has always been a difficulty in the treatment of black and odorous water bodies.
Relying on physical and chemical methods has the problems of large investment, long construction period, unsustainability, and secondary pollution, and the treatment effect is not satisfactory

preparation example Construction

[0028] The preparation method of the above-mentioned microbial bacterial agent for repairing the water environment is to successively inoculate and cultivate Bacillus pumilus, Pseudomonas putida, Bacillus polymyxa and Aspergillus niger for mass production respectively, and then mix each The mass-production cultured strains were prepared by cross-antagonistic culture.

[0029] Its specific preparation method comprises the following steps:

[0030] Step 1, inoculate Bacillus pumilus (Bacillus pumilus), Pseudomonas putda (Pesudomonasputda), Bacillus polymyxa (Bacillus polymyxa (Prazmowski) Mace) and Aspergillus niger (Aspergillus niger van Tieghem) respectively on the solid medium, Inoculate and cultivate for 36 to 48 hours at a temperature of 28 to 30°C; agar is used as a solid medium.

[0031] Step 2. Inoculate the strains cultivated in step 1 into liquid culture medium respectively, and cultivate them for 36-48 hours at a culture temperature of 28-30° C. and a shaker flask sp...

Embodiment 1

[0041] The implementation site of this example is Shanghai Minhang Youyou Village

[0042] The river is about 1000 meters long, 10-15 meters wide, 1-1.5 meters deep, and 0.4-0.6 meters thick. Due to the natural discharge of a large amount of domestic sewage and industrial sewage, the river water has been seriously polluted for a long time. The river water bloom phenomenon is obvious, showing eutrophication, low transparency, black silt, reaching the standard of mild black odor. Three groups of monitoring sections are set up in this river course as required, and the specific treatment conditions are shown in Table 1 below.

Embodiment 2

[0047] The implementation site of this example is Changxing Wei, Fanchang, Wuhu

[0048] The channel is about 3000 meters long, 20-30 meters wide, 0.8-2.2 meters deep, and 0.5-1.0 meters thick. The river course is located in the Economic Development Zone of Fanchang County, and the enterprises in this area are mainly food processing enterprises. Due to the natural discharge of a large amount of industrial sewage and domestic wastewater, the river water has been seriously polluted for a long time. The river water bloom phenomenon is obvious, showing eutrophication, low transparency, and black silt, reaching the severe black and odor standard. At present, water quality maintenance measures mainly rely on physical measures such as dredging, but black and smelly phenomena are repeated, seriously affecting the surrounding living and production activities. According to the requirements, 4 groups of monitoring sections are set up in this river course, and the specific treatment con...

Abstract

The invention discloses a microbial agent for repairing the water environment, a preparation method thereof and a method for repairing the water environment combined with a submerged biological bed. The microbial agent includes the following strains by weight percentage: Bacillus pumilus 20-40% , Pseudomonas putida 20-35%, Bacillus polymyxa 15-25% and Aspergillus niger 20-35%. The above-mentioned strains are purified and extracted for many times, mass-produced and cultivated for multiple generations, and then placed in submerged biological beds and arranged in corresponding positions in the water body. Each strain continues to multiply, ferment, and release enzymes, thereby Continuously degrade ammonia nitrogen, organic phosphorus and sulfide in water. In the way of ecological supplementation, the restoration of the water body is carried out to achieve the treatment effect of removing black, deodorizing and paying off.

Description

technical field [0001] The invention belongs to the technical field of treatment of black and odorous water bodies, and in particular relates to a microbial agent for repairing a water environment and a preparation method thereof, and a method for repairing a water environment combined with a submerged biological bed. Background technique [0002] At present, there are a large number of black and odorous water bodies of different sizes and uneven distribution in many areas of our country. One of the important reasons for these black and odorous water bodies is the enrichment and excess of ammonia nitrogen, organic phosphorus, and sulfide. However, the treatment volume is large, the content is low, and the enrichment of ammonia nitrogen and organic phosphorus due to non-point source pollution has always been a difficulty in the treatment of black and odorous water bodies. Treatment by physical and chemical methods has the problems of large investment, long construction period...
