The Live Pig Excrement Fermentation In Situ Treatment Technology Bed Environmental Effects And Application

In recent years, with the development of agriculture and the structure adjustment, the pig industry is booming production condition, according to2010statistics bureau of agriculture haimen, haimen scale poultry and animal feces in pig farm produce58540tons. Pig pig urine and some ill waste place sends the stench and toxic or harmful gases, such as the feces of pathogenic microorganisms on soil environment, atmospheric environment and water pollution and so on, all send to us in warning, pigs pollution to the solution of the problem the urgent, it has become a rural and suburban ZhenCun, taking one of the main source of environmental pollution. At present, the pig feces treatment means haimen composting fermentation and development is mainly methane project and so on, but due to the limitations of the technology itself, scope, investment cost factors, difficult to win a decisive results. For example haimen scale livestock and poultry field methane project37, of which the pig farm methane project only16, and the dispersion livestock and poultry in most of the livestock and poultry waste disposal are not effectively, thus to the periphery environment pollution caused by and influence. From haimen environmental protection bureau report center of calendar year about raising pigs feedback pollution environment also can see complaint, pigs pollution treatment such as investment, promote the difficult question, cause pollution becomes the focus of pig haimen complaint content, also become haimen city in the process of building national ecological stumbling block.In this case, the urgent need to seek a more ideal, effective pig feces treatment technology, and fermentation bed technology is such kind of pig feces in situ treatment technology.Fermentation bed ecological pigs technology is a kind of pollution, the zero discharge of organic agriculture technology, is to use special fermentation of the organic mat absorption, degradation, digestive pig excrement, achieve odourless and tasteless, harmless purpose, is a new type of pig excrement fermentation in bed treatment technology. We use the pilot to the promotion, to take a pilot of the pig farm most supercilious men experiment, collect the pig farm construction quality data before and after the surrounding environment, so as to prove the live pig excrement fermentation in situ treatment technology no pollution, bed zero emissions environmental effects. Through the experiment we found fermentation in situ treatment technology bed basic achieved the expectations.Pig feces treatment means haimen composting fermentation and development is mainly methane project and so on, but due to the limitations of the technology itself, scope, investment cost factors, difficult to win a decisive results. We will fermentation in situ treatment technology and bed methane project and composting fermentation technology is also the environment effect comparison, fermentation in situ treatment bed in many aspects have advantage.For large scale for the pig farm, methane project through the development for many years, relatively mature technology, for large-scale pig farm, as equipment and administration in place, relative to the full play of their pigs in the positive role of waste disposal, and fermentation technology can increase the bed pigs pigs effect, save labor cost, raise pigs waste disposal of in situ more advantages. For small retail pigs is concerned, because the fermentation bed pigs technology feasible and investment not too big. general midstream residential can bear all, therefore, fermentation bed is applicable to scale the pig farm pigs and production condition of most of the family retail raising pigs.
