Abstract
The invention relates to a method for preparing straw dairy manure organic fertilizer, comprising the steps of mixing a certain amount of straw powder or rice chaff, and the like, with swamp liquid; preparing into swamp liquid straw mixture with proper water content; evenly mixing the prepared swamp liquid straw mixture, the dairy manure with proper water content and zymogeneous bacteria agent; sequentially firstly fermenting, periodically piling, secondly fermenting, periodically piling, dehydrating, and stopping fermenting; and processing, packing or finish machining to prepare the organic fertilizer. The method harmlessly processes the swamp liquid and prepares the organic fertilizer therewith, not only solves the river pollution problem caused by randomly discharging the swamp liquid, but also can use the organic fertilizer for crops.
Description
Technical field
The present invention relates to a kind of method for preparing straw dairy manure organic fertilizer.
Background technology
In the face of the pollution problem that agriculture prodn brings, a lot of local construction methane-generating pits solve organic pollution, yet the biogas residue and biogas liquid that large and medium-sized biogas engineering discharged has caused secondary pollution owing to not being utilized effectively.Some engineerings are handled the back qualified discharge once more with natural pond liquid, though this has been avoided secondary pollution, have caused the very big wasting of resources.Usually, the biogas residue and biogas liquid as fertilizer sources can directly be applied to the farmland, though this can reach good effect, receives crop-planting seasonal effect and transportation trouble easily, and nobody is ready so to do.Therefore, much directly enter the stream, polluted water body and environment without natural pond slag, the natural pond liquid sewage further handled and exceed standard greatly.
Feces of livestock and poultry produces biogas and has just utilized its bioenergy; From the environment protection angle; Be to digest in the feces of livestock and poultry input water that but fecaluria is shunted originally, its sewage load increases 3-5 times more than than original, and intractability is higher; Become important pollution sources, so envrionment conditions is relatively poor near many large and medium-sized methane stations.Therefore the processing of biogas residue and biogas liquid is not good at, and the discharging waters causes that water pollution has become pressing problem anxious to be solved.
Summary of the invention
The technical problem that the present invention will solve is: for solving the defective that exists in the above-mentioned technical background, a kind of method for preparing straw dairy manure organic fertilizer is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method for preparing straw dairy manure organic fertilizer the steps include: that a. mixes a certain amount of straw powder or rice chaff etc. with natural pond liquid, be modulated into the natural pond liquid stalk mixture that contains suitable moisture; B. fresh cow dung being carried out moisture content regulates; C. synthetic natural pond liquid stalk mixture and the cow dung and the fermenting agent that contain amount of water are mixed, stop fermentation through one time fermentation, turning regularly, Secondary Fermentation, turning regularly, dehydration back successively then; D. process organic commercial fertilizer through after processing, packing or the precision work.
Further; Natural pond liquid stalk mixture described in the present invention is processed by crushed stalk post-absorption natural pond liquid to suitable moisture; Producing the adding proportion that should be noted that natural pond liquid and straw powder in the process is 1: 0.46-0.56; Mixing time is not less than three minutes, and the water cut of the mixture of processing is 60%-70%.
Further; Because the former water cut of fresh cow dung is more than 83%; Carry out fermentation maturity and must regulate moisture; The cow dung that contains amount of water described in the present invention be by fresh cow dung through sun power dehydration or add straw powder, rice chaff or the material after the fermentation maturity dehydration in the c step is partly returned, the moisture of cow dung is adjusted to processes below 70%.
Further, the adding proportion the preceding natural pond of fermentation liquid stalk mixture and cow dung among the present invention is 1: 0.54-0.65, C/N ratio is 20-30.
Further, after stopping, fermentation need make more to meet the commercialization characteristics that postprocessing working procedures mainly comprises: impurity elimination, screening, pulverizing to the further processing treatment of material.
Further, in order to improve the field fertilizer efficiency of organic commercial fertilizer, need be to the further processing treatment of material, to process biological organic fertilizer, functional fertilizer.Main additive is function yeast, trace element, soil improvement agent and biological catalyst, and wherein function yeast comprises bacillus megaterium, colloid bacillus cereus, bacillus cereus and Rhodopseudomonas palustris.
The invention has the beneficial effects as follows that the present invention handles the natural pond liquid pollution-free and can utilize natural pond liquid to process organic commercial fertilizer, both solved random discharging natural pond liquid and the stream pollution problem that causes, the fertilizer of processing can be used for the field crop again, kills two birds with one stone.
