Description

Saline-alkali soil radical treatment device by membrane isolation pool method

Technical Field

The utility model belongs to a device is administered in the farmland, in particular to pond method saline and alkaline land radical cure device is kept apart to membrane.

Background

The existing saline-alkali soil of about 15 hundred million mu in China, including salinized farmland and grassland, has the tendency of continuously expanding and spreading, which causes great harm to the agriculture and animal husbandry and ecological environment in China, so that the saline-alkali soil is urgently treated, is not ignored, and is concerned with offspring and descendants. At present, the main methods for saline-alkali soil treatment comprise four methods: the physical method, the chemical method, the biological method and the scientific and technical method can not take out the saline-alkali from the soil, but press the saline-alkali underground, the saline-alkali still remains in the soil, the saline-alkali harm is only temporarily relieved and cannot be radically cured, and the problems of relapse, rebound and the like exist. Particularly, the foreign soil, the water injection and the salt pressing can send a large amount of salt and alkali into the ground when the rice is planted, the most harm is to accelerate the salinization of the underground water, and the underground water is permanently polluted, so that the rice is endless. The reasons for the poor results of these treatments are: firstly, saline-alkali soil in the soil is not removed, and the saline-alkali soil is only temporarily pressed underground and can return to the ground at any time. Secondly, chemical and biological activities are not sustainable, and the possibility of upward returning of saline and alkaline under the ground still exists. Thirdly, the saline-alkali content of the severe saline-alkali soil is very high, and the root cannot be treated. This is the main reason why saline-alkali soil cannot be radically treated up to now. The most effective method for radically treating the saline-alkali soil is to take out and move out the saline-alkali soil, prevent the saline-alkali soil from returning upwards, prevent the saline-alkali soil from being taken out, radically treat the saline-alkali soil permanently, and cause temporary rebound and recurrence even if the saline-alkali soil is treated, because the saline-alkali soil still remains in the soil, the harm source is not eliminated.

Disclosure of Invention

The utility model aims at solving the problem that pollution groundwater and saline alkali can not be radically treated in saline-alkali soil treatment, and providing a device for radically treating saline-alkali soil by a membrane isolation pool method, which can effectively prevent saline-alkali soil from being salinized, thoroughly radically treat saline-alkali soil, and can not recur and rebound.

The utility model discloses a set up isolation pond and sunning pond in saline and alkaline land soil, isolation pond and sunning pond lay with prevention of seepage membrane, including bottom of the pool and pool wall, constitute complete pond, the upper portion of isolation pond is saline and alkaline soil layer, has a water-collecting layer below saline and alkaline soil layer, has an isolation layer between saline and alkaline soil layer and water-collecting layer, prevents that the mud sand in the saline and alkaline soil layer from sneaking into the water-collecting layer, still has the drinking-water pipe in isolation pond, the drinking-water pipe passes through the water pump, the raceway is linked together with the sunning pond.

The lower part of the isolation pool is also provided with a water collecting pit, so that water in the water collecting layer flows into the water collecting pit, and the lower end of the water pumping pipe extends into the water collecting pit, so that water can be pumped outwards better.

An exhaust pipe is arranged in the isolation pool, so that air in the water collecting layer can be conveniently exhausted.

The utility model has the advantages that:

1. set up the isolation pond in saline and alkaline land soil, keep apart the soil outside the pond and the soil in the pond, through watering in to the isolation pond, reach the purpose of washing the ground and discharging saline and alkaline, the isolation pond has both prevented to wash the saline and alkaline water infiltration underground after the ground, avoid polluting groundwater, saline and alkaline in the saline and alkaline soil outside the pond has also been prevented to soil infiltration in the pond, guarantee that the landmass after administering does not rebound, the recurrence, and the time is short, and it is fast to take effect, administer one just intact, reach the purpose of radical treatment saline and alkaline land, the land utilization ratio has been improved, and simultaneously, can also prevent desertification soil infiltration, leak water and evaporation, protect water, protect fertile, improve crops output.

2. Set up the sunning pond beside the isolation pond for place the saline and alkaline water that takes out from the isolation pond, saline and alkaline water collects the processing through natural sunning evaporation concentration after, turns into the resource with the wastes material, and changing waste into valuables sells as industrial chemicals, increases the income, offsets and administers the investment, reduces saline and alkaline land treatment cost, utilizes the improvement output to enlarge the investment source of administration.

3. Set up the water-collecting layer below saline and alkaline soil layer, both can collect the saline and alkaline water after washing the ground in the stage of washing the ground, can collect unnecessary moisture in the soil again after finishing washing the ground, can also collect natural precipitation and store, draw out when needs, irrigate ground crop, liquid manure cyclic utilization, soil moisture conservation is effectual.

4. Set up the isolation layer between saline and alkaline soil layer and water-collecting layer, prevent that the mud sand in the saline and alkaline soil layer from sneaking into the water-collecting layer, ensure that the water-collecting layer has the water-collecting function all the time.

5. The lower part of the isolation pool is provided with the water collecting pit, so that water in the water collecting layer flows into the water collecting pit, and the water is convenient to be pumped outwards better.

6. The exhaust pipe is arranged in the isolation pool, so that air in the water collecting layer can be conveniently discharged, and more water can be stored.

7. The utility model discloses mainly used salinization's farmland replanting and the recovering and the salinization soil development and utilization of grassland expand arable land, grassland and forest area, administer desertification development farmland, meadow, forest, resume ecology, the environmental protection also can be used to arid water shortage area and build the high standard farmland, improves grain yield, still can be used to the saline and alkaline land development arable land, increases arable land area, enlarges the construction land supply and solves arable land account for the uneven scheduling problem of benefit.
