Closed-loop type garbage digesting and saline-alkali soil sandy land repairing and garbage dump in-site repairing method

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...

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 amount of fresh water is needed, and our country is a country seriously short of fresh water! Agricultural technology improvement Improve soil composition and structure, enhance soil permeability, and accelerate salt leaching through deep plowing, land leveling, filling soil, covering grass, turning silt, covering sand, adding organic fertilizers, etc., but the current effect is not great

However, it cannot permanently solve the problem of saline-alkali soil, and it is prone to secondary hazards! The production cost is too high to be popularized on a large scale! It is also difficult to quickly cultivate plants, because the soil is barren and has poor water retention, and there is not enough nutrients to make it difficult for plants to survive. There are many technical problems in the use
