Embodiment 1

[0025] The microbial bacterial agent that is used to process catering grease wastewater comprises fungus 10wt% (5wt% of Saccharomyces cerevisiae, Candida lipolytica 5wt%), bacterium 40wt% (Bacillus subtilis 10wt%, Bacillus licheniformis 10wt%, Rhodopseudomonas palustris bacteria 10wt%, Streptococcus thermophilus 10wt%) and carrier 50wt% (light calcium carbonate 40wt%, talcum powder 10wt%).

[0026] Preparation method: weigh the above bacteria powder and carrier respectively according to the above proportions, and mix them evenly to obtain the microbial bacteria agent for treating catering oil wastewater of the present invention. After determination, the total number of live bacteria of the microbial agent is 1.0×10 10 CFU / g, bacterial agent fineness 95% passed through 40 mesh sieve.

[0027] The above-mentioned microbial agents are used to treat wastewater: the microbial agents are inoculated in batches in the wastewater aeration tank every day, and the inoculation amount is ...

Embodiment 2

[0029] The microbial bacterial agent that is used to process catering grease wastewater comprises fungus 20wt% (Mucor raceme 10wt%, Candida lipolytica 10wt%), bacterium 40wt% (Bacillus subtilis 10wt%, Bacillus licheniformis 10wt%, Bacillus amyloliquefaciens Bacillus 10wt%, Bacillus pumilus 5wt%, Thiobacillus ferrooxidans 5wt%) and carrier 40wt% (zeolite powder 30wt%, talc powder 10wt%).

[0030] Preparation method: weigh the above bacteria powder and carrier respectively according to the above proportions, and mix them evenly to obtain the microbial bacteria agent for treating catering oil wastewater of the present invention. After determination, the total number of live bacteria of the microbial agent is 5.0×10 9 CFU / g, bacterial agent fineness 95% passed through 30 mesh sieve.

[0031] The above-mentioned microbial agent is used to treat wastewater: the microbial agent is inoculated in the wastewater aeration tank every day, and the inoculation amount is about 1.0×10 accord...

Embodiment 3

[0033] Microbial agents used to treat catering oily wastewater include fungi 40wt% (total Aspergillus oryzae 20wt%, Candida lipolytica 20wt%), bacteria 30wt% (Bacillus subtilis 10wt%, Bacillus amyloliquefaciens 10wt%, Bacillus pumilus 5wt%, Rhodopseudomonas sphaericus 5wt%) and carrier 30wt% (water-soluble starch 20wt%, anhydrous glucose 10wt%).

[0034] Preparation method: weigh the above bacteria powder and carrier respectively according to the above proportions, and mix them evenly to obtain the microbial bacteria agent for treating catering oil wastewater of the present invention. After determination, the total number of live bacteria of the microbial agent is 3.0×10 9 CFU / g, bacterial agent fineness 95% passed through 30 mesh sieve.

[0035] The above-mentioned microbial agent is used to treat wastewater: inoculate the microbial agent in the wastewater aeration tank every day, and the inoculation amount is about 1.0×10 according to the live bacteria content in the input ...

Abstract

The invention belongs to the technical field of catering wastewater treatment, and particularly relates to a microbial agent for the treatment of catering oily wastewater and a treatment method thereof. The microbial agent includes fungi and bacteria and, the fungi include any one or more combinations of Mucor roxianus, Mucor racemosus, Aspergillus oryzae, Aspergillus niger, Candida lipolytica, Candida tropicalis and Saccharomyces cerevisia; and the bacteria include any one or more combinations of Bacillus subtilis, Bacillus licheniformis, Bacillus amyloliquefaciens, Bacillus pumilus, Rhodopseudomonas palustris, Rhodopseudomonas sphaeroides, Thiobacillus ferrooxidans and Streptococcus thermophilus. The degradation rate of the microbial agent to oils and fats can reach 90% or above.

Description

technical field [0001] The invention belongs to the technical field of catering wastewater treatment, and in particular relates to a microbial agent and a treatment method for treating catering wastewater. Background technique [0002] Catering grease wastewater refers to the oily hogwash discharged from catering industries such as restaurants, guesthouses, and unit canteens, including rice washing water, rice soup, leftovers, fish bones, bone residue, melon and vegetable peels, etc. The main components of catering oil wastewater are leftover food and water, animal fat, starch, dietary fiber and other organic matter, which have the characteristics of high nutrient content, high water content, high oil and salt content, perishable fermentation and odor. If it is discharged without treatment, it will seriously affect the surrounding environment. [0003] At present, the main method of treating catering oily wastewater is: firstly, solid-liquid separation is carried out on the...
