Description
Technical field:
The present invention relates to a kind of soil organic amendment technical field, refer in particular to a kind of industrial waste and town and country organic waste of utilizing and be prepared from, and the method for suitable southern acid organic modifying agent for low-yield soil.
Background technology:
Along with developing rapidly of city, population increases, and the sanitary sewage quantity discharged increases severely.The treatment rate of domestic sewage of American and Britain, method, moral, day, Australia, developed country such as new all reaches 100%; Domestic gap is bigger, and it is 25% that the exemplary city of national environmental protection also only requires wastewater treatment rate.According to reports, domestic each treatment rate of domestic sewage in 2000 only reaches 3%; Guangdong reaches 12% approximately, and only concentrates on Guangzhou, Shenzhen, Zhuhai, several cities such as Foshan.In addition, to the treatment process of dewatered sludge, then with landfill, burn and drop into river, river, lake, Hai Weizhu, resource utilization is agricultural still to belong to pre-test.In recent years owing to introduce external comparatively advanced dewatering machine equipment, and in settling tank, add polymeric flocculant and make body refuse directly form the lower fine and close small muddy pill of water content, thereby be the mud that solid form has changed the flow morphology of dewatering machine formation in the past, and also eliminated stink greatly.But this solid-state moisture percentage in sewage sludge still reaches about 75%, and volume is big, also has a lot of unfavorable factors in the farmland if directly be back to use as fertilizer or soil improvement agent.If this mud is directly carried out drying, also remain at following point: the one, the energy consumption height, processing cost is big; The 2nd, dried material is hard especially, increases the difficulty of pulverizing again; The 3rd, the market outlook of pulverizing exsiccant mud merely are limited; The 4th, if product marketing is bad, scheme jettisons disposal in addition, and this not only increases trucking costs, also can cause secondary environmental pollution.Therefore, the problem that exists at its physicochemical character is in conjunction with other waste material, and the treatment of wastes with processes of wastes against one another is turned waste into wealth, and carries out biochemistry and piles harmless treatments such as corruption, opens up out the channel of agricultural resource utilization, is a kind of essential measure.
In addition, Guangdong is the native place of south of the Five Ridges medical science, also is the main product ground of south of the Five Ridges herbal medicine.Guangdong Provincial Party committee, " about building the strong decision that economizes of Chinese materia medica " made by provincial government, issued that " the strong enforcement outline of economizing (2006～the year two thousand twenty) of Chinese materia medica is built in Guangdong " and " Guangdong Province's Chinese materia medica development " Eleventh-Five Year Plan " " have further promoted developing rapidly of Guangdong Chinese materia medica.According to statistics, between the existing herbal medicine processing in Guangdong pharmaceutical factory more than 120, year processing medium-height grass spice (siccative) nearly 500,000 tons produces the organic solid waste material dregs of a decoction about 1,500,000 tons (weight in wet bases).Herbal medicine is with woody, the root of draft, stem, leaf, flower, really, seed or complete stool be used as medicine, through the effectively purification of medicinal component, its dregs of a decoction moisture about 70%, the dry organic content reaches 80～90%, the nutrient total content of mineral elements such as nitrogenous, phosphorus, potassium, calcium, magnesium is up to 3% to 5%, and pH5.38～6.04 are a kind of fine organic materialss.Only there are at present indivedual places to utilize the small portion draft dregs of a decoction as the organic materials of culturing edible mushrooms, the feed that also has small portion flower, fruit waste material to be used as the fowl poultry or to breed fish, minimum part is arranged by near the flower-grower the pharmaceutical factory, the orchard worker is as fertilizer, but the dregs of a decoction that the whole province utilizes as agriculture and animal husbandry are less than 30%, still have the dregs of a decoction 70% or more to go out of use in the deserted mountain, the rural area is outside of the city or the sink node fire burns, or it is smelly to let alone to become corruption, both waste resource, polluted environment again.And over nearly 30 years, Agricultural Development has relied on chemical energy source excessively, a large amount of executes partially, lavishment chemical fertilizer causes soil organic matter content sharply to be reduced, the sandization of soil, acidifying are very serious, sand, acid, sticking, thin, harden, organic poor, nutrient is uneven, heavy metal contamination etc. has become southern low-yield land general character, the serious loss of water and soil, the pollution that superfluous chemical nutrient element is serious rivers water resources and underground water; And the qualitative change of agricultural byproducts product is bad, also has influence on human body health.Therefore, improve the soil, enrich organic fertilizer, improve Food Quality, become the tight demand of social sustainable development.Along with the development of world economy, the facility cultivation of agricultural more and more plays an important role; But also there are many shortcomings in the facility soil cultivation, and being difficult to regulation and control, disease and pest difficulty as soil secondary salinization, nutrition, to give prevention, production operation heavy etc.; Therefore the facility soilless substyate cultureization is trend of the times.The facility cultivation development of the nearly agricultural industry of flowers and plants during the last ten years is rapid, particularly green agricultural product production.
Summary of the invention:
The objective of the invention is to overcome the shortcoming of existing soil improvement agent product, a kind of city dehydrated sludge that utilizes is provided, materials such as herbal medicine pharmacy waste residue and calcium carbonate alkalescence industrial waste, the expensive soil improvement agent of the alternative tradition of development and production, more inexpensive than currently available products, the soil organic amendment of improving the soil with better function.
