Description
Technical field
The present invention relates to technical field of fertilizer, refer to a kind of microbial fertilizer and preparation method thereof especially.
Background technology
Point out in the 17th Session of the General Assembly report of party: " strengthen Energy resources saving and ecological environmental protection, strengthen the capability of sustainable development.Adhere to economizing on resources and fundamental state policy, the relation vital interests of the people and Chinese nation's survival and development of protection of the environment.The extrusion position of industrialization, modernization development strategy must be placed on building a resource-conserving and environment-friendly society.Improve and be conducive to save energy resource and the law of preserving the ecological environment and policy, accelerate development Sustainable development institutional mechanisms.Exploitation and promoting is saved, substitute, the advanced practical technique of recycle and pollution administration, and development clean energy and renewable energy source, protection soil and water resources, the Energy resources of building science utilize system, improve Energy resources utilising efficiency.Development environmental protection industry.Emphasis strengthens prevention and control of water, air and soil pollution, improves town and country human settlement.Strengthen water conservancy, forestry and grassland construction, strengthen desertification, Rocky Desertification Control, promote restoration of the ecosystem.Strengthen reply climate change capacity building, for protection global climate makes new contribution.”
China's applying quantity of chemical fertilizer ranks first in the world, but chemical fertilizer utilization ratio is but in downtrending year by year.The excessive chemical fertilizer of using of current China arrives the limit, which results in that Soil structure is destroyed, a series of serious problems such as nature biotechnology diversity and ecosystem stability reduction.Wideling popularize bio-fertilizer coordinates chemical fertilizer application to be exactly one of method addressed these problems.
As chemical fertilizer, bio-feritlizer is strategic resource equally, and bio-feritlizer strategic significance has obtained country and paid much attention to." State Council is about the decision accelerating cultivation and development strategy new industry " that State Council issues is pointed out to want " actively promoting green agricultural biological product ", and bio-feritlizer is then one of staple product of green agricultural biological product.
Water resources ensures the fundamental prerequisite of human survival, water conservation, prevents sewage to the pollution of environment, is that the mankind benefit substantial responsibility throughout the ages.In order to improve the serious situation of China's water resource pollution, from " 95 " period, waste water control problem is paid attention to fully, and city sewage treatment works project development is rapid.
Along with the continuous construction of sewage work in all parts of the country, the concomitant output of sewage disposal---municipal sludge is constantly produced, and annual newly-increased sludge disposal has has not only occupied a large amount of soil, but also brings new pollution.Present situation sewage treatment project is only a link of sewage environment protection treating, does not form health, an optimum environmental protection treatment chain.After 20 century 70s, the environmental problem that municipal sludge produces becomes increasingly conspicuous.Accelerate in Urbanization in China, urban population sharply increases, under country drops into ever-increasing promotion to environmental protection cause, wastewater treatment in China factory quantity increases year after year, sewage treatment capacity improves constantly, and consequent mud is also keeping growth by a relatively large margin.According to research institute of Chinese Academy of Sciences statistics, the wet mud of each municipal sewage plant of China generation in 2010 reaches more than 3,000 ten thousand tons, accounts for more than 5% of China's year solid waste discharge amount.
For the process of mud, the most frequently used is landfill at present, burning disposal, water body are dissolved, but these methods self still exist certain pollution and defect.
1, landfill.Transudate in waste pit gentle cognition welding, polluted air and water source.In transudate, objectionable impurities enters Water table meeting polluted underground water environment; The gases methane that landfill yard produces, do not take appropriate measures and can set off an explosion, in addition, the place being applicable to Sludge landfill is also more and more limited because of a large amount of generation of municipal sludge, the U.S. has closed a large amount of landfill yards in recent decades, and EU countries's landfill disposal in 1992 accounts for 40%, 2005 years has reduced to 17%, and regulation bury fill out material be only limitted to organic content < 50g/kg.
2, power plant's burning disposal.The gases such as the Dioxins produced during burning cause topsoil, and sludge heavy-metal also spreads with flue dust.In addition, 2-4 times that cost is other treatment process is burned.
3, water body is dissolved.Water body is dissolved and is not in fact fundamentally solved environmental problem, and causes pollution of the sea.The U.S. has forbidden to Ocean dumping mud for 1998, and European Union also specifies to forbid utilizing ocean lignin-sludge from 1999.
Obviously, traditional method for sludge treatment also exists various drawback.Under the overall background of global resources anxiety, change traditional sludge treatment and Land use systems, reduce the secondary pollution of mud, development sludge resource technology, has become one of problem of China and even whole world environmental protection circle extensive concern.
Summary of the invention
