Problems solved by technology

And the economic benefit is poor
(3) Biogas production, in recent years, is beneficial to the production of biogas by organic matter fermentation, but it has not been popularized and popularized. The main reason is that the cost of biogas production is too high. Pure biogas factories generally lose money, and the utilization rate of biogas residue is not high. Farmers use biogas The enthusiasm of the slag is not high, and the biogas slag has little effect on improving production
(4) Incineration, incineration has become the main way to dispose of organic waste, but waste incineration plants have huge investment, and the flue gas emitted by incineration cannot meet the current technical standards, causing pollution to the surrounding environment
The existing problem is that a large am...

Embodiment 1

[0024] Embodiment 1 The method for the ecological restoration of closed-loop saline-alkali barren beach and garbage dump, taking the repair of Zhuangchang garbage dump in Pizhou City as an example:

[0025] The Zhuangchang garbage dump was repaired in 2011. Before the restoration, the wind was blowing and garbage was flying all over the sky, and black and smelly water overflowed in rainy days. The place was full of mosquitoes, flies and mice, and the surrounding people complained. The municipal government decided to carry out ecological restoration, and the solution we provided was adopted.

[0026] The first step is garbage classification.

[0027] The garbage dump covers an area of ​​200 mu, and the main component is 150,000 tons of household garbage. After the analysis, we employ the direct shift to remove garbage. Build a fermentation biogas plant at the garbage dump, designed to process 400 tons of garbage per day, and build 15 biogas fermentation tanks with a capacity ...

Embodiment 2

[0045] Example 2 The value of the closed-loop saline-alkali wasteland and the method of ecological restoration of garbage dumps

[0046] (1) Market value

[0047] The market price of soil remediation agent is 1,000 yuan / ton, and the income is 500,000 yuan per day. The total daily income gross profit is 574,250 yuan, and the gross profit generated by cleaning up garbage places is more than 143.5625 million yuan. 205 workers were placed for the local area to solve the employment problem. After 9 months of production, the garbage in the garbage dump was cleaned up, the garbage site was cleaned up, and 2 tons of repairing agent produced per mu was applied, and it was plowed and leveled for two months. The bacteria in the soil repairing agent were cultivated to decompose the garbage residues, and the adsorption trees were planted for ecological restoration. At the end of 2015, the soil was tested in full compliance with the basic farmland standards of the Ministry of Agriculture....

Abstract

The invention provides a closed-loop type garbage digesting and saline-alkali soil sandy land repairing and garbage dump in-site repairing method. The method comprises the steps that garbage is classified firstly; micropopulation in the bovine rumen is added, fiber in garbage is rapidly decayed, and starch type garbage is rapidly decomposed; after rapid decomposition and decaying, the mixed thermophile colony for high-temperature degrading of starch and proteins and decomposing of wood fiber is added for continuous fermentation, and the lactic acid bacteria colony is added for metal removal. After desiccation, a soil repairing agent made of plant ash is added; the salt and alkali sandy soil is treated; and the prepared soil repairing agent is sufficiently mixed with soil, and soil is repaired. According to the method, a pollution source can be eradicated from the source, and the garbage is turned into wealth and is beneficial to returning to the nature.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and ecological system reconstruction and restoration, and relates to environmental governance and a method for ecological system restoration thereof, in particular to a method for closed-loop garbage storage and restoration of saline-alkali sandy land and in-situ restoration of garbage dumps. technical background [0002] There are about 10 billion tons of waste in China, and the effective disposal rate of more than 2 billion tons of new waste generated every year is less than half, and organic waste accounts for more than half. The natural corrosion of organic waste has caused huge pollution to the environment. With the acceleration of my country's urbanization process, the amount of urban greening waste, kitchen waste, and urban sewage is also increasing, and a large amount of sludge and other organic wastes are also increasing. The phenomenon of garbage siege is serious, and th...
