Description
Technical field
The present invention relates to the purified treatment reuse technology field of rural sewage, in particular it relates to a kind of salt-soda soil bitter
Processing method and system.
Background technology
China there are about 0.27 hundred million hectares of salt-soda soil, wherein 0.06 hundred million hectares of arable land, 0.21 hundred million hectares of saline-alkali wasteland, main point
Cloth compares and concentrates the area that is distributed in flakes to have Qaidam in northeast, North China, Northwest inland area and North of Yangtze River coastal area
Basin, Tarim Basin periphery oasis and Northern Piedmont of Tianshan Mountains bajada area, Hetao Plain, Yinchuan Plain, North China are put down
The former and Huanghe delta.
Salt-soda soil is formed under certain natural conditions, and its essence formed is mainly various ease of solubility salts on ground
Redistributing for horizontal direction and vertical direction is made in face, so that upper soll layer of the salinity in collection salt area is built up.
The factors such as weather acts on, farming technique is unreasonable, level of ground water is raised, can cause the salinization of soil.
Perniciousness harm cause it is a large amount of in, low-yield land, the anions and canons being harmful to crop are more, make large area soil resource difficult
To utilize, overall productivity in agriculture declines.Saline-alkali soil is administered at present it is most useful that to soil by the way of washed off soil
Carry out salt discharge alkali, the i.e. desalinization of soil by flooding or leaching.Irrigation and drainage system is excavated on salt-soda soil, water is poured into salt-soda soil in a manner of broad irrigation, is made
Soil salt dissolves, oozed under in topsoil it is soluble it is saline and alkaline be discharged in deep soil or elute away, alkali is arranged in side infiltration
Canal is excluded.It is to water resource degree of dependence height, it is necessary to consume around salt-soda soil more than 50% freshwater resources.
China's saline alkali land drainage water is very big, and this part is leached the salt and alkali to get off, if do not handled scientifically,
Over time, the serious ecological problems such as Secondary Saline and the surface water pollution of non-wetland with saline-alkaline certainly will be caused.
Brackish water recharge soil is obtained using salt-soda soil row's alkali water in a canal purified treatment, not only Salt And Alkali Tolerance is planted but also there is economic valency
The plant of value, make salt-soda soil is throughout the year green to plant covering, the improvement of essence will be produced to the overall ecological environment of China.General feelings
Under condition, irrigated land using salt-soda soil row's alkali water in a canal purified treatment, chemical fertilizer, pollution by pesticides are few, particularly salination desert, are even more
No pollution.Tight balance is in national cultivated land resource and population speedup, and generally by the overall background of different degrees of agricultural pollution
Under, it transform saline-alkali wasteland as good farmland, not only can provides newly-increased farmland for country, but also freshwater resources danger can be alleviated significantly
Machine, arable land crisis of resource and soil Saline-alkalized land crisis.The plantation of green ecological circular agriculture pattern is promoted for China, is being produced
While giving birth to huge economic benefit, huge ecology and social benefit more are brought to country.
The content of the invention
