Embodiment 1

[0023] The microbial preparation used for water body deodorization, its active ingredient is composed of the following components by weight: Thiobacillus denitrification 30 parts; 15 parts of single cell bacteria.

[0024] Microbiological preparations are made through the following steps:

[0025] S1: Carry out step-by-step seed expansion culture for Thiobacillus denitrificans, Bacillus pumilus, Candida utilis, Lactobacillus acidophilus, and Pseudomonas stutzeri, respectively, to obtain seed culture liquid after expansion.

[0026] S2: Connect the seed bacterium solution obtained in step S1 into the fermenter respectively, and the inoculation amount is 5-10% of the fermentation medium by weight, and different genus are fermented and cultivated separately, and 2 or 2 of the same genus Mixed fermentation culture of more than one strain.

[0027] S3: Take the seed bacteria liquid after fermentation and cultivation, in parts by weight: 30 parts of Thiobacillus denitrificans, 20 ...

Embodiment 2

[0036] Microbial preparations for water body deodorization, the mixed bacterial solution is composed of the following parts by weight: Thiobacillus denitrification 25 parts; Bacillus pumilus 15 parts, Candida utilis 15 parts, Lactobacillus acidophilus 10 parts, Pseudomonas stutzeri 10 copies of bacteria. Wherein, the preparation method and application are the same as in Example 1.

[0037] After testing, the comparison of pollutant content before and after the treated sewage is shown in the table:

[0038] project name

Embodiment 3

[0040] Microbial preparations for water body deodorization, the mixed bacterial solution is composed of the following parts by weight: Thiobacillus denitrification 35 parts; Bacillus pumilus 25 parts, Candida utilis 25 parts, Lactobacillus acidophilus 20 parts, Pseudomonas stutzeri 20 copies of bacteria. Wherein, the preparation method and application are the same as in Example 1.

[0041] After testing, the comparison of pollutant content before and after the treated sewage is shown in the table:

[0042] project name

Abstract

The invention provides a microbial preparation for water deodorization. The active ingredients of the microbial preparation are prepared from, by weight, 25-35 parts of thiobacillus denitrificans, 15-25 parts of bacillus pumilus, 15-25 parts of candida utilis, 10-20 parts of lactobacillus acidophilus and 10-20 parts of pseudomonas stutzeri. After the microbial preparation is prepared, black and odorous sewage can be cleaned through the steps of sewage pretreatment, sewage re-treatment and microbial oxidation. The microbial preparation has the advantages that activity is high, reproduction is quick, environment friendliness is achieved, pollution is avoided, cost is low, and strains are reasonable in compatibility, symbiotic, coordinated and not antagonistic. The water deodorization efficiency is high, and especially the good removal effect is achieved for hydrogen sulfide and ammonia gas.

Description

technical field [0001] The invention involves multi-stage treatment of water, waste water or sewage, and in particular relates to a microbial preparation for deodorizing water bodies and its preparation method and application. Background technique [0002] Water bodies such as lakes and rivers in cities are an important part of urban human settlements. However, due to their characteristics of easy pollution, small water environment capacity, and poor self-purification ability of water bodies, they can easily become sinks for residents' domestic sewage, rainwater, and garbage. , which leads to a large consumption of dissolved oxygen in the water body, resulting in the lack of oxygen in the water body and a black and odorous state, causing the entire ecosystem to be in crisis. Black and smelly urban rivers have become a common pollution problem in many large and medium-sized cities in my country, seriously affecting the lives of residents, the image of the city and the ecologi...
