Abstract
The invention discloses a method for producing particle organic fertilizer through activated sludge and belongs to the technical field of fertilizer preparation. According to the method for producing the particle organic fertilizer through the activated sludge, sludge from a sewer system and sludge from the bottom of a pond are fully utilized to conduct aeration, then wheat bran and straws are added to conduct hardening culture and fully-mixing and fermentation, and the organic fertilizer is obtained. The method for producing the particle organic fertilizer through the activated sludge has the advantages that the nitrogen content of the organic fertilizer ranges from 20% to 28%, the phosphorus content ranges from 18% to 22%, the yield of crops is increased by 20-30 kg each mu after the fertilizer is used, and the fertilizer effect is good; the soil structure can be improved, nutritious ingredients required by crops are provided, and growth of crops is effectively promoted; the sludge from the sewer system and sludge from the bottom of the pond are fully utilized, the wheat bran and straws are added to conduct hardening culture and fully-mixing and fermentation so as to obtain the organic fertilizer, waste materials are changed into things of value, renewable resources and economic development are achieved, the problem of environmental pollution caused by sludge is solved, occupation of land resources is reduced, and the living environmental quality of the surrounding residents is improved.
Description
Technical field
The present invention relates to a kind of method that active sludge produces granular organic fertilizer, belong to fertilizer preparing technical field.
Background technology
Along with the development of Chinese Urbanization and the universal of aquatic organism aquaculture, sanitary sewage and breeding wastewater roll up, and the excess sludge production produced therefrom will constantly increase; Containing a large amount of organic matters in mud, if do not deal carefully with, meeting causes pollution in various degree to ecotope, the treatment process of current mud piles up burning, landfill, but pile up the secondary pollution that burning can cause environment, landfill can take a large amount of land resources and cost of investment is high, poor processing effect.
Containing a large amount of nitrogen promoting plant and crop growth in mud, phosphorus, the nutritive ingredients such as potassium, fertilizer efficiency is better, stabilization can be reached through compost treatment, the object of innoxious and resource utilization, compost be one by mesophile, thermophile bacteria carries out the stabilization process of aerobic decomposition to organism, be characterized in that self can produce certain heat, and high-temperature duration is long, do not need external heat source, can reach innoxious, so, if sludge treatment can be used as fertilizer, both the harm that mud causes environment can have been avoided, the recycling of mud can be realized again, reduce taking of land resources, the sustainable economic development of China are had great importance.
Summary of the invention
Technical problem to be solved by this invention: for containing a large amount of nitrogen promoting plant and crop growth in mud, phosphorus, the nutritive ingredients such as potassium, if pile up, burning disposal, not only cost of investment is high, secondary pollution is caused to environment, take a large amount of land resources, also cause the drawback of the wasting of resources, provide a kind of method that active sludge produces granular organic fertilizer, present method makes full use of water drain domestic sludge, pond bottom sludge treatment is produced into fertilizer, turn waste into wealth, solve the problem of mud environmental pollution, decrease appropriation of land, effect of fertilizer is good.
