my country is a large country of pig, pig and pork products account for about half of the world production! With the increasing importance of environmental sanitation, the discharge of pig manure in the breeding process has become a larger production process. Expenditure, how to deal with a large number of pigments, and on the future of future farming, how to deal with this expenditure will only be in the price of the feed, accounting to a small spending on each pig body, today I want to be The farmers explore how to use butces within a reasonable range to achieve energy saving and emission reduction. How to deal with pigs, then let's take a look at learning.

Pig manure fermentor

[ 123] 1. Pig manure returning

It is used as fertilizer pig manure to return to the important part of my country's traditional agriculture, \"grain-pig fertilizer grain\" traditional agricultural production, That is, there are more pigs, and the fat multi-grain is more typical ecological agriculture. The pig manure is also played an important role in improving the soil and improving agricultural production. The way the pig manure is still related to the tanity process. Some countries in the world use water to clear the feces, and use tankers after fermentation of manure, it is used in cultivated land with sowing or special machine. This method of pig manure treatment is relatively simple, but there is enough fermentation tank or fermentation Can. Pig pigs in dry feces, feces can be treated by soil, and the soil obtain fertilizer while purifying the feces, saving the processing cost.

But the soil has limited purification capacity, excessive application is easy to cause contamination, freshure fermentation in the soil Production heat and its decomposition is unfavorable to crop growth, so the application amount is limited, and the amount of cultivated land per hectare is 7.5-9 tons. After the pig manure is applied, the above contradiction can be solved, and the fertility can be improved. During the rotation of pig manure, the temperature can reach 50 to 70 ° C, kill the manure of the manure of microorganisms, parasitic eggs and weed seeds, the fertilizer after pig manure is low, no odor, belongs to late Effective fertilizer, easy to use. The simple method of rusted compost is: on the floor of the cement or plastic film, or in the cement tank, the mixed material piles will grow strips, high 1.5-2. O rice, 1.5-3.0 meters wide, the length is determined according to the site.

Third, the biogas

Sewage can be used for the biogas, biogas is anaerobic microorganism (mainlyMethane bacteria decompose the mixed gas produced by carbonaceous organic matter in the dungal. Biogas is an energy source, which can be used for lighting, fuel, power generation, and the like. The fermented bridges can be used as fertilizers, and the biogas solution can be bio-treated in a row of fish. The type of biogas fermentation is: high temperature fermentation (45-55 ° C), medium temperature fermentation (35-40 ° C) and normal temperature fermentation (30-35 ° C). In my country, it is commonly used in normal temperature fermentation, and its suitable conditions are: 1) temperature 25-35 ° C; 2 Acid alkalinity (pH) 6.5-7.5, PH low can be adjusted with limestone or grass ash; 3 carbon nitrogen ratio 25-30: 1 4 sufficient organic matter, generally per cubic meters of biogas ponds is added to 1.6-1.8 kg of solid feedstock; 5 suitable volume, the volume of the fermentation pond is low in each pig 0.15 cubic meters of normal temperature fermentation efficiency, biogas, biogas After further processing, secondary pollution can be caused. If medium temperature or high temperature fermentation is used, increase gas efficiency, shorten the fermentation time, or reduce the difficulty of secondary treatment, and reduce secondary pollution. Pig manure biogas in the north, due to the low temperature of the temperature, is relatively wide in the southern region.

High temperature good oxygen fermenter

Using organic wastewater planting water gourd and gentle greening and other aquatic feed, with water gourd to high concentration of manure, fine Green Ping is resistant to the concentration of manure, high concentrations of organizer water in the water gourd, 7 days to 8 days to achieve absorption purification. Of course, while pig farm produces pig manure, it is not only possible to improve the problem of pig manure, but a large number of sewage in the farm needs to be resolved, and the sewage treatment is also an important part of the aquaculture industry.
