Embodiment 1

[0046] Prepare culture media according to the culture media of Bacillus, lactic acid bacteria and nitrifying bacteria, and sterilize them at 121°C for 20 minutes. For Bacillus, Lactobacillus casei, Lactobacillus brucei-like and nitrifying bacteria, inoculate the inoculated liquid culture medium except for the nitrifying bacteria at 40°C, and cultivate other bacteria in a shaking table at 37°C for 30-36h, and the rotating speed of the shaking table is 120r / min, so that the strain is in the late logarithmic growth period, collect the bacterial liquid, centrifuge at 5000r / min for 10 minutes, discard the supernatant, take the precipitate, add 20% sterile glycerol, mix well and freeze-dry.

[0047] Methylotrophic Bacillus, Bacillus subtilis, and Bacillus amyloliquefaciens were mixed at a ratio of 1:1:1 as Bacillus, and Lactobacillus casei and Lactobacillus brucei were mixed at a ratio of 1:1 as lactic acid bacteria. Take 24 parts of nitrifying bacteria, 9 parts of Bacillus, and 24...

Embodiment 2

[0049] Prepare culture media according to the culture media of Bacillus, lactic acid bacteria and nitrifying bacteria, and sterilize them at 121°C for 20 minutes. For Bacillus, Lactobacillus casei, Lactobacillus brucei-like and nitrifying bacteria, inoculate the inoculated liquid culture medium except for the nitrifying bacteria at 40°C, and cultivate other bacteria in a shaking table at 37°C for 30-36h, and the rotating speed of the shaking table is 120r / min, so that the strain is in the late logarithmic growth period, collect the bacterial liquid, centrifuge at 5000r / min for 10 minutes, discard the supernatant, take the precipitate, add 20% sterile glycerol, mix well and freeze-dry.

[0050] Methylotrophic Bacillus, Bacillus subtilis, and Bacillus amyloliquefaciens were mixed at a ratio of 1:1:1 as Bacillus, and Lactobacillus casei and Lactobacillus brucei were mixed at a ratio of 1:1 as lactic acid bacteria. Take 24 parts of nitrifying bacteria, 6 parts of bacillus, and 36...

Abstract

The invention discloses GS microbial inoculum for disposing life wastewater and the application of the GS microbial inoculum and belongs to the field of biotechnology. The GS microbial inoculum is constituted by, by weight, 3-9 parts of bacillus, 24-48 parts of lactic acid bacteria and 12-24 parts of nitrobacteria, wherein the bacillus is constituted by methyl trophism bacillus, bacillus subtilis and bacillus amyloliquefaciens, and the lactic acid bacteria are constituted by lactobacillus casei and lactobacillus buchneri. According to the GS microbial inoculum for disposing the life wastewater and the application of the GS microbial inoculum, through identification and safety analysis on bacterial strains, reasonable compatibility is conducted on the bacillus, the lactic acid bacteria and the nitrobacteria, and the GS microbial inoculum for disposing the life wastewater is obtained. After the life wastewater is disposed through the GS microbial inoculum, the removal rate of COD and the removal rate of NH<4>-N reach over 90%.

Description

technical field [0001] The invention belongs to the field of biological technology, and in particular relates to a GS bacterial agent for domestic sewage treatment and its application. Background technique [0002] Water is an essential substance for all living things on earth and is closely related to human life. However, with the rapid development of society and economy and the acceleration of urbanization, a large amount of industrial sewage and domestic sewage are produced every day. The problem of water pollution has become the focus of people's attention. An important indicator of the degree of civilization. Domestic sewage mainly includes non-toxic organic compounds such as sugar, starch, lipoprotein and urea, which mainly cause eutrophic pollution of rivers and lakes. In recent years, the seven major water systems including the Yangtze River, Yellow River, Pearl River, Songhua River, Huaihe River, Haihe River, and Liaohe River have all been polluted to varying degr...
