Problems solved by technology

[0010] The technical problem to be solved by the present invention is: currently, the COD treated by photosynthetic bacteria fails to reach the emission standard, the cost of algae digestion and treatment is high, and it needs to be diluted with water. And the technology of supporting breeding water, which can not only be suitable for large-scale consumption of livestock manure, no need to add water to dilute, meet environmental protection requirements, but also can be processed at low cost, and also has the function of recycling livestock waste gas and reducing carbon emissions. The effect is very good

Embodiment 1

[0050] A process for engineering bacteria and algae to ferment livestock manure water and supporting breeding water, specifically as follows:

[0051] The livestock manure discharged from the livestock house is first separated by the first-stage solid-liquid separation device, and the separated solid waste is processed by a solid-state fermentation system; the separated waste liquid is separated again by the second-stage solid-liquid separation device, and the separated solid waste is passed through The solid-state fermentation system treats, and the separated waste liquid is pre-treated by a physical treatment device to obtain a pre-treated liquid. The pretreatment solution is connected to the first photosynthetic reactor containing the composite photosynthetic bacteria group, the pretreatment solution is used as a substrate for cultivating the composite photosynthetic bacteria group, and the composite photosynthetic bacteria group fermentation liquid is obtained after expandi...

Embodiment 2

[0062] The present embodiment is the process of processing the water of pig manure water and supporting cultured shrimp and mussels, specifically as follows:

[0063] It is used in a pig farm with 5,000 pigs in Beinan Township, Pingtung County, Taiwan Province. The pig farm has used probiotics to feed pigs for a long time. The feces contain facultative anaerobic bacteria (mainly cellulase bacteria) at 5.72± 2.88×10 6 Individuals / ml, facultative anaerobic lactic acid bacteria (mainly Enterococcus) 1.44±5.29×10 6 per milliliter, resulting in the COD value of 12000-18000mg / L when the fresh manure comes out, because the bacillus group and lactic acid bacteria group rapidly proliferate in the sewage concentration pool, and degrade the macromolecules in the wastewater into volatile acids, low sugars, amino acids, etc. Small molecules, so the COD value has dropped rapidly to 6400-7800mg / L before entering the solid-liquid separation.

[0064] The pig farm adopts a fully exposed floo...

Embodiment 3

[0093] The difference between this embodiment and embodiment 1 is that the types of livestock and poultry breeding are different in this embodiment, specifically as follows:

[0094] For farms of different types of livestock and poultry, the scale can be converted from the breeding volume of chickens and cattle to the breeding volume of pigs. The specific conversion is carried out in accordance with GB 18596-2001, that is: 30 laying hens are converted into 1 pig, and 60 broiler chickens are converted into 1 pig. One pig, 1 dairy cow is converted into 10 pigs, and 1 beef cattle is converted into 5 pigs; the type of aquaculture is selected according to the local climate conditions and market capacity.

[0095] The process of the present invention has a reasonable and simple preparation method, effectively reduces the cost of animal husbandry wastewater treatment, and has great added value in cooperation with aquaculture production.

Abstract

The invention discloses a technology for fermenting livestock manure and matched aquaculture water through engineering bacteria and algae. The technology comprises the following steps: (1) treating the livestock manure discharged from a livestock house to obtain a pretreated solution; (2) inoculating a first photosynthetic reactor containing a compound photosynthetic bacterial flora with the pretreated solution, and performing amplification culture to obtain a compound photosynthetic bacterial flora fermentation solution; pumping out the compound photosynthetic bacterial flora fermentation solution, dividing the compound photosynthetic bacterial flora fermentation solution into two parts, adding one part of the compound photosynthetic bacterial flora fermentation solution into an aquaculture pond, and adding the other part of the compound photosynthetic bacterial flora fermentation solution into a second photosynthetic reactor containing a compound algal flora for amplification culture; (3) performing amplification culture in the second photosynthetic reactor to obtain a compound algal flora fermentation solution; (4) pumping out 0.5-1.5% of water in the aquaculture pond first and then supplementing equal amount of the mixed fermentation solution into the aquaculture pond; (5) treating the water pumped out from the aquaculture pond, returning the water to the livestock house, and reusing the water as recycled water. The technology has the advantages as follows: the technology is applicable to large-scale disposal of the livestock manure, clear water is not required to be added for dilution, environmental requirements are met and the like.

Description

technical field [0001] The invention relates to a process for treating waste water, in particular to a process for fermenting livestock manure and supporting breeding water with engineered bacteria and algae. Background technique [0002] Livestock manure and sewage have a high biological aerobic content and contain suspended solids, nitrate, phosphorus, and a large number of pathogenic microorganisms and parasites. Even if they are discharged for a long time after treatment, they will also cause eutrophication and increase in turbidity of surface water. , polluted water can also spread diseases, especially zoonotic diseases, which seriously endanger the health of humans and animals. [0003] Modern wastewater treatment technologies are divided into three categories: physical treatment, chemical treatment, and biochemical treatment. Among them, physical and chemical methods often require the purchase of special equipment or the addition of a large amount of chemicals, and th...
