Problems solved by technology

[0005] But, due to the complex hydrology and water quality in various places, the inoculum agent cultivated by the prior art has poor adaptability, and it is difficult to achieve the expected biological treatment effect in the actual use of river sewage treatment; and the seed bacteria in the inoculum agent cultivated by the prior art are all purchased Microbial inoculation agent, the cost is higher

Embodiment 1

[0012] A method for culturing inoculants for water purification, firstly taking the target water of the water body to be repaired; then pumping 850L of target water into a 1000L biological incubator, and mixing microbial nutrients and microbial inoculants to the target according to the following weight percentages Water: 70% of target water, 20% of microbial nutrients, and 10% of microbial inoculants. When mixing, first mix the target water and microbial nutrients, and adjust the PH value of the mixture to the same as the PH value of the water to be restored , and finally add microbial inoculants; then the mixture is aerated and aerated for 3 days, aerated and aerated twice a day, and the dissolved oxygen concentration is maintained between 2 and 3 mg / L. When the bacterial concentration reaches 10 2 ~10 3 When the concentration of dissolved oxygen is reduced to the dissolved oxygen concentration of the water to be repaired, when the concentration of bacteria reaches 10 5 ~10 ...

Embodiment 2

[0016] A method for culturing a bacterial agent for water purification, firstly taking the target water of the water body to be repaired; then pumping 800L of the target water into a 1000L biological incubator, and mixing the microbial nutrient and the microbial inoculum to the target according to the following weight percentages Water: 60% of target water, 25% of microbial nutrients, 15% of microbial inoculants. When mixing, first mix the target water and microbial nutrients, and adjust the PH value of the mixture to the same as the PH value of the water to be restored , and finally add microbial inoculants; then the mixture is aerated and aerated for 4 days, aerated and aerated 3 times a day, and the dissolved oxygen concentration is kept between 2 and 3 mg / L. When the bacterial concentration reaches 10 2 ~10 3 When the concentration of dissolved oxygen is reduced to the dissolved oxygen concentration of the water to be repaired, when the concentration of bacteria reaches 10...

Embodiment 3

[0020] A method for culturing a bacterial agent for water purification, firstly taking the target water of the water body to be repaired; then pumping 900L of target water into a 1000L biological incubator, and mixing microbial nutrients and microbial inoculants to the target according to the following weight percentages Water: 65% of target water, 20% of microbial nutrients, and 15% of microbial inoculants. When mixing, first mix the target water and microbial nutrients, and adjust the PH value of the mixture to be the same as the PH value of the water to be repaired , and finally add the microbial inoculant; then the mixture is aerated and aerated for 5 days, aerated and aerated twice a day, and the dissolved oxygen concentration is kept between 2 and 3 mg / L. When the bacterial concentration reaches 10 2 ~10 3 When the concentration of dissolved oxygen is reduced to the dissolved oxygen concentration of the water to be repaired, when the concentration of bacteria reaches 10 ...

Abstract

The invention discloses a culture method of a fungicide for water purification. The method comprises the following steps: taking target water of water to be restored; mixing 60-70wt% of the target water, 20-25wt% of a microbial nutrition agent and 10-20wt% of a microbial inoculum through first mixing the target water with the microbial nutrition agent, then adjusting the pH value of the obtained mixed solution to be same to the pH value of restored water, and finally adding the microbial inoculum; and carrying out aeration oxygenation on the mixed solution 2-3 times every day for 3-5d to keep the concentration of dissolved oxygen to be 2-3mg / L, reducing the concentration of the dissolved oxygen to the concentration of the dissolved oxygen in the restored water when the concentration of florae reaches 10<2>-10<3> / mL, and completing the method when the concentration of the florae reaches 10<5>-10<6> / mL. Compared with like products in the prior art, the fungicide cultured through the method has the advantages of good adaptability, good practical sewage biological treatment effect and low cost.

Description

Technical field: [0001] The invention belongs to the field of restoration and treatment of eutrophic water bodies, and in particular relates to a culture method of a bacterial agent for water body purification. Background technique: [0002] With the development of urbanization and industrialization, as well as the large-scale use of chemical fertilizers in agriculture, a large amount of untreated urban domestic sewage and industrial and agricultural sewage flows into lakes and rivers, causing the accumulation of nitrogen, phosphorus and other nutrients, promoting algae and other aquatic organisms Mass reproduction, the transparency of the water body decreases, and even the formation of "algae blooms", the water quality deteriorates, and odors are produced, which in turn leads to the accelerated development of the eutrophication process of the water body. [0003] Due to the particularity of eutrophic surface waters, conventional remediation methods are difficult to play an ...
