The invention discloses a method for preparing liquid manure from piggery cultivation waste in a zero-release mode. Liquid piggery cultivation waste obtained by carrying out dry-wet separation on the piggery cultivation waste is effectively used for preparing the liquid manure, waste is turned into wealth, the method is simple, easy to implement, environmentally friendly, free of pollution and low in treatment cost, and the problems that piggery cultivation waste water is high in treatment cost and difficult to treat are solved.
Description
Technical field
The present invention relates to a kind of pig farm breeding waste treatment process, the pig farm breeding waste of particularly a kind of zero release prepares the method for Liquid Fertilizer.
Background technology
Pig-breeding industry is in a flourish stage, and current China has developed into one of pork big producing country of the world.China intensive industrialized piggery high speed development, if but a large amount of wastes that aquaculture produces fail to deal carefully with in time, having exceeded around, just may there is a series of problem of environmental pollution in the detergent power of physical environment.The discharge of livestock and poultry cultivation production produced pollution thing has become one of most important agricultural pollution source of China, causes great harm to the production of plant's periphery, living environment.
Pig farm waste mainly refers to the material being difficult to recycle produced in the production process of pig farm, mainly comprises pig manure, waste water etc.These materials cause crossed contamination to each ring layer of water body, soil, air and biology.But, also containing abundant organism and mineral in waste.How processing not pollute environment even turns waste into wealth, and comprehensive utilization, plays the problem that economic benefit is puzzlement pig industry always.
Conventional process pig waste treatment methods is roughly divided into two classes: dry shovel process and mixed process, and two kinds of methods all have serious in insoluble problem.Conventional dry dunghill fertilizer takes the several months, takes up an area again wide, sends to feel bad smell, and attracting flies, contaminate environment, serious can cause food poisoning.Owing to lacking feasible technique means, the live pig ight soil of current most of pig breeding farm can only unprocessed direct stacking, and like this, these live pig ight soil both polluted environment, wasted resource again.People are in the treatment process of the live pig ight soil of the large-scale pig breeding farm of exploration.The best way is that live pig ight soil is placed methane-generating pit fermentative processing; cannot the problem of disposal and utilization but this method also also exists large amount of sewage that live pig manure fermentation produces and excrement slag later; therefore; carry out treatment scale pig-breeding prevention and cure of pollution problem with regard to a set of administering method of needs, at utmost solution pig-breeding waste water and solid waste are difficult to the problem of process.
Summary of the invention
A kind of pig farm breeding waste of zero release is the object of the present invention is to provide to prepare the method for Liquid Fertilizer, the pig farm liquid breeding waste of pig farm breeding waste after separating dry space from moist space effectively can be utilized and make Liquid Fertilizer, turn waste into wealth, method is simple, environment friendly and pollution-free, processing cost is low, solves pig farm cultivating wastewater purification cost high, reluctant problem.
The technical solution adopted for the present invention to solve the technical problems is:
The pig farm breeding waste of zero release prepares a method for Liquid Fertilizer, comprises the following steps:
(1) by pig farm breeding waste separating dry space from moist space, the pig farm liquid breeding waste after separating dry space from moist space is collected;
(2) in the liquid breeding waste of pig farm, add bamboo vinegar liquid regulates pH to 5.5-7.0 must to ferment basal liquid;
(3) in fermentation basal liquid, add the EM bacterium liquid accounting for fermentation basal liquid weight 0.3-0.5%, control leavening temperature 10-35 DEG C, carry out aerobic fermentation;
(4) gained fermented liquid after aerobic fermentation is carried out solid-liquid separation, using the solid part of separation as solid organic fertilizer, the liquid portion of separation obtains Liquid Fertilizer through high-temperature sterilization.Liquid after high-temperature sterilization both directly can be used as Liquid Fertilizer, also as one of Liquid Fertilizer raw material, can add other nutrient element, make various Liquid Fertilizer.
Innovative point of the present invention is:
1, adopt bamboo vinegar liquid to regulate pig farm liquid breeding waste pH, play multi-effect:
The pH of 1.1 pig farm liquid breeding wastes, generally at 8.5-10.5, be not suitable for doing liquid fertilizer, and natural bamboo vinegar liquid pH is less than 3.2, is good conditioning agent;
1.2 bamboo vinegar liquid are owing to can kill, containing some germs, worm's ovum containing certain acetic acid;
1.3 bamboo vinegar liquid self have a lot of nutritive ingredients, as while pH adjusting agent being also a kind of well Liquid Fertilizer nutrient raw material composition.
2, after bamboo vinegar liquid regulates pH, adopt the method process of EM fermentation, kill further, contain some germs, worm's ovum, increase available nutrient content in liquid simultaneously.
3, finally high-temperature sterilization is adopted to liquid, the virus in liquid and parasitic ovum can be killed, improve safety in utilization.
4, the present invention is first using direct as Liquid Fertilizer or Liquid Fertilizer basic material after the liquid breeding waste process of pig farm, open up the utilization ways that pig farm liquid breeding waste is new, and without any waste water, waste sludge discharge, the solid part be separated, as solid organic fertilizer, can merge with the pig farm solid breeding waste after separating dry space from moist space and directly use as fertilizer as Fertilizer application or after fermenting further.
As preferably, contents on dry basis≤6% of pig farm liquid breeding waste in step (1).Control contents on dry basis≤6% of pig farm liquid breeding waste, be easier to like this make Liquid Fertilizer.
As preferably, described in step (2), the pH value of bamboo vinegar liquid is less than 3.5.
As preferably, in step (3), the viable count of EM bacterium liquid is greater than 0.9 hundred million/milliliter.
As preferably, fermentation 7-10 days when leavening temperature is 20-35 DEG C in step (3), ferment during 10 DEG C≤leavening temperature <20 DEG C 11-15 days.
As preferably, in step (4), gained fermented liquid after aerobic fermentation is carried out solid-liquid separation by 160 mesh sieves.By 160 orders, be about 0.1 millimeter, namely remove being greater than 0.1 millimeter of solid particulate suspended, and be less than the out of question of this value, macrobead activity is little, does Liquid Fertilizer plant not easily to absorb, and also easily causes plug-hole in spray application simultaneously.
As preferably, in step (4), the temperature of high-temperature sterilization is 125-130 DEG C, and the time is 30-60 minute.
The invention has the beneficial effects as follows: the pig farm liquid breeding waste of pig farm breeding waste after separating dry space from moist space effectively can be utilized and make Liquid Fertilizer, turn waste into wealth, method is simple, environment friendly and pollution-free, processing cost is low, solve pig farm cultivating wastewater purification cost high, be difficult to the problem effectively utilized.
