Problems solved by technology

[0002] At present, the treatment of urban domestic waste is relatively simple, generally incineration, landfill, causing certain pollution to the surrounding environment, such as the generation of toxic gases such as dioxins during incineration)
The landfill causes secondary pollution, and there are many potential harmful factors. The first is the anaerobic fermentation process, and the organic matter is anaerobically decomposed to produce gases such as CH4CO2 and H2S.
It is also a good environment for the growth and reproduction of microorganisms, creating a rather complex and huge bacterial group, including coliform bacteria and fungi that are harmful to human health. In addition, in order to ensure that the landfill is impermeable, the cost of materials is also very expensive

Embodiment 1

[0012] Take 20% by weight of sludge, 20% of straw, 10% of excrement, 10% of bagasse, 10% of swill, and 30% of water retaining agent; pass the above-mentioned filter mud, straw, feces, bagasse, and swill through Two times of fermentation to make compost, and finally adding water retaining agent is produced by Hunan Jinshu Technology Co., Ltd.

[0013] Lay this product 50 cm thick on the 5-meter-deep sandy soil, and water it regularly, the soil quality of the sandy land has been improved, but half a year later, weeds will grow on it.

Embodiment 2

[0015] Take 5% of sludge, 60% of straw, 10% of excrement, 5% of bagasse, 5% of slops, and 15% of water-retaining agent by weight; pass the above-mentioned filter mud, straw, feces, bagasse, and swill Two times of fermentation to make compost, and finally add water retaining agent for production by Changsha Xiangyao High-tech Development Co., Ltd.

[0016] On a sandy land of about 5 acres, the sand layer is 5 meters, and the product is laid about 1 meter on the sand layer, rapeseed is sown, and watered regularly. After 2 months, it is found that the rapeseed has formed seeds and the seeds are saturated. .

Embodiment 3

[0018] Take 20% of straw, 10% of human excrement, 20% of livestock and poultry excrement, 10% of sludge, 10% of bagasse, 5% of swill, 15% of fly ash, and 10% of water retaining agent in weight ratio. The filter mud, straw, feces, bagasse, and slops with the above contents are fermented once to make compost, and finally, fly ash and water-retaining agent are added for production by Changsha Xiangyao High-tech Development Co., Ltd.

[0019] In a sandy land of about 3 mu, the sand layer is up to 10 meters. Do a tree planting test on the sandy land, first wipe and dig a sand pit on the sand layer, fill the sand pit with this product, plant the tree on this product, and then On the three acres of land, lay a layer of this product with a thickness of 50 cm, and continue to plant saplings at intervals and water regularly. After 1 year, it became a green space.

Abstract

A sand-controlling modified oil fertilizer is composed of the components with the following weight content: sewage sludge 5-20%, stalk 20-60%, feces 10-40%, bagasse 5-10%, hogwash 5-10%, and water-loss reducer 5-40%; the oil fertilizer is obtained by preparing the lime sludge, stalk, feces, bagasse and hogwash with the above content to prepare compost and finally adding the water-loss reducer. The sand-controlling modified oil fertilizer provided by the invention can effectively treat the household rubbish to facilitate the rubbish become a fertilizer which can control the desert excellently and improve the desert oil quantity, at the same time an approach for effectively settling the garbage is provided and a virtuous circle is formed.

Description

technical field [0001] The invention relates to a kind of compost for crops and fertilizer for improving desert and barren land, which comprehensively utilizes wastes produced in daily life and excrement of human body or animals. Background technique [0002] At present, the treatment of municipal solid waste is relatively simple, generally incineration and landfill, which cause certain pollution to the surrounding environment, such as the generation of toxic gases such as dioxins during incineration). The landfill causes secondary pollution, and there are many potential harmful factors. The first is the anaerobic fermentation process, in which organic matter undergoes anaerobic decomposition to produce gases such as CH4·CO2 and H2S. It is also a good environment for the growth and reproduction of microorganisms, creating a rather complex and huge bacterial group, including coliform bacteria and fungi that are harmful to human health. In addition, in order to ensure that the...
