Abstract
An organic fertilizer is prepared from city sewage and sludge, ecological bacteria, passivating agent of heavy metal, and pH regulator through proportionally mixing, inoculating, fermenting, drying granulating and sieving. It has no environmental pollution.
Description
Technical field
A kind of fertilizer of sewage sludge preparation that utilizes of the present invention relates to a kind of fertilizer and preparation method thereof, especially utilizes municipal effluent, mud to turn waste into wealth, and is a biotechnology that is beneficial to the sewage comprehensive regulation of environment protection.
Background technology
Along with the develop rapidly of city each side, the human continuous expansion that natural resources exploitation is utilized, the wealth that creates improves constantly human standard of living.Meanwhile, the negative effect that is produced is: a large amount of waste water,waste gas and industrial residue and human lives's rubbish, sanitary sewage serious environment pollution, and brought on a disaster and crisis to the mankind.Shanghai is the city of a beauty, particularly after the reform and opening-up, the urban construction accelerated development, urban population is on the increase, institute's water amount of blowdown is dosage progressively, and municipal government invests the municipal effluent comprehensive regulation and improves Suzhou River water quality to The World Bank Loan every year, just in recent years, obtained first-stage success.But how to solve the difficult problem that has been manipulated so of city sewage and sludge, especially Shanghai is faced with weight break point in line with international standards, to establish the image of its modernized cosmopolis to the world, therefore, explore, study the effective ways of practicable city sewage and sludge safe disposal, become an extremely urgent thing of comprehensive environmental improvement.
Shanghai City 12 families of existing sewage work, be distributed in Xuhui, Changning, Zhabei, Hongkou, Minhang, Wusong, Putuo District respectively, be accompanied by every day about 350,000 tons sewage by biochemical purification, thereby generation every day, nearly 1500 tons water ratio was 80% mud, particularly Shanghai City waste water control first and second phases of projects builds up, building of the third stage of the project, and the bamboo plantation that is about to start building, white Dragon River two big Sewage Plant, a large amount of city sewage and sludges that also will produce, give the sewage comprehensive regulation that lacks ripe sludge ultimate disposal technology work, bring huge burden.
For a long time, the Shanghai Urban sewage sludge concentrates a little, directly is transported to the usefulness that fertilizer and soil improvement are done in the rural area, suburbs.Because water ratio reached 80% when city sewage and sludge dispatched from the factory, and was the clay shape, was difficult for scattering, because of its physical property, after the drying, hardness is very high, is difficult for fragmentation, is difficult to be directly used in well the farmland.Simultaneously, contain pathogenic microorganism and parasitic ovum in the mud without the strictness processing, will be detrimental to health, cause secondary pollution, and in the process of the fermentation of in the farmland, becoming thoroughly decomposed naturally, also will produce bad, the mashed root of seed development, form problems such as disease and insect.
Summary of the invention
The object of the present invention is to provide a kind of is raw material with the sewage sludge, utilizes the microbial acclimation technology to prepare a kind of fertilizer and preparation method thereof.
The object of the invention can be achieved through the following technical solutions: the fertilizer that utilizes the sewage sludge preparation, with the sewage sludge is raw material, it is characterized in that: the former bacterium with Shanghai City city sewage and sludge employing Changbai Mountain, northeast, be combined into ecological flora, make fertilizer through fermentation.
On the technique scheme basis, fertilizer each component proportioning:
Active sludge (water ratio is 70%) 90-110
Heavy metal deactivator 9.5-10.5
PH conditioning agent 2.0-3.0
Swelling agent 1.5-2.5
Fertilizer efficiency poiser 1.5-2.5
Zymophyte group agent 1-2
Make thus fertilizer, water ratio is 70%, organic content is more than 39%, be graininess.
This fertilizer that utilizes sewage sludge to prepare can be used for the base fertilizer in booth vegetable, melon and fruit, fruit-bearing forest, lawn, nursery etc. and topdresses.
The preparation method of described fertilizer: steps in sequence is mixing, inoculation, fermentation, drying, granulation, screening, weighing, packing.
Described fertilizer one time fermentation abrasion cycle is 4-7 days, 55 ℃-75 ℃ of leavening temperatures.
Adopt the distinctive former bacterium in Changbai Mountain, northeast, scientific and reasonable becomes ecological flora with the multiple beneficial life assemblage, short its in overall situation (soil) with subenvironment (fertiliser granulates) in reciprocal, collaborative, symbiosis propagation, form delicate, complexity and stable microflora, and with its vigorous life Metabolic activity, provide various nutritive elements and a large amount of physiological activity materials (vitamin H, microbiotic, tethelin, VITAMIN, amino acid etc.) to farm crop endlessly, with adapt to farm crop in the whole production phase demand to various nutritive ingredients.
Superiority of the present invention is: because the present invention adopts suitable bacteria agent, reasonably fill a prescription, make the microbial bacteria combination rationally, quick heating when therefore having the waste fermentation, one time fermentation is respond well, thoroughly eliminate stench, fully save characteristics such as nutrient and suitability for industrialized production running cost are low from damage.
