InactiveCN101565684AShort degradation cycleStrong bacterial activityFungiBacteriaMicroorganismStart time
The invention discloses a method for making a fermenting bed for ecological pig breeding by using composite strain culture, in particular relates to a method for making the fermenting bed by using a plurality of microorganisms. The invention comprises the steps of preparing the culture and making the fermenting bed. In the invention, the culture is mainly prepared by microzyme, lactobacillus, actinomycetes, photosynthetic bacterium and mycelial fungus according to proportion. The culture after being activated is stirred uniformly with organic padding pro rata, piled, fermented, prepared into the fermenting bed, and then can be used for breeding live pigs. The method solves the problems of long fermenting starting time of the organic padding, unstable microbial inoculum, strict requirements on the fermenting conditions and materials as well as short service life in the existing ecological pig breeding method. The method uses the composite strain culture to build ecological colony house; the fermenting starting time of the organic padding is short, which can be 1 to 2 days in summer and 3 to 5 days in winter; the strain activity is strong; the decomposing process can be finished in 1 to 3 days; the effect lasts for long; and the fermenting bed can be continuously used for 5 to 8 years. Moreover, the method is green and environmental friendly.

Totally-enclosed type multifunctional high-speed incinerating device and production process thereof

The invention belongs to the technical field of refuse treatment, and relates to a totally-enclosed type multifunctional high-speed incinerating device and a production process thereof. The device is characterized in that an incinerator sequentially communicates with a purifying condensing device, an exhaust fan, a totally-enclosed cooling tank and a totally-enclosed ecological purifying area through conduits; an oxygen output tube of an oxygen generator correspondingly communicates with a first oxygen supplementing tube, a second supplementing tube and an air inlet tube. The production process is that oxygen is supplemented to an inner chamber of the incinerator, and connected wastes fed into the incinerator is incinerated once through the oxygen, and the waste gas is incinerated and pyrolysed at high temperature twice and then cooled and decoked; the decoked waste gas is purified and condensed through the purifying condensing device, then fed into the totally-enclosed cooling tank to be cooled and finally subjected to biodegradation in the ecological purifying area; the waste gas containing the rest toxic and harmful substances is introduced into the incinerator again through the air inlet tube to be pyrolysed at high temperature. Therefore, the totally-enclosed type circular treatment mode of the waste is achieved. The device and the production process have the advantages that the wastes can be treated without leakage and with zero emission.
