Description
Technical field
The present invention relates to a kind of agricultural brackish water Asia desalination treatment system, especially relate to a kind of agricultural brackish water Asia desalination process irrigation system integrated with water-fertilizer-pesticide.
Background technology
China is the country of a serious water shortage, and be again an agricultural irrigation big country, irrigation water use accounts for 62% of total supply simultaneously, makes the fast-developing ever-increasing water requirement of economic society make the contradiction of supply and demand for the water resource more and more outstanding.But China's brackish water resource distribution is wide, especially easily there is arid North China, northwest and coastal area, be extensively dispersed with brackish water resource, it is one of important measures solving irrigating water quality shortage that research and utilization brackish water carries out irrigating.Brackish water is directly used in irrigation and easily causes soil dissoluble too high levels, cause salt damage (Salt Strees Condition), simultaneously in the not enough situation of irrigation quantity, water salt can be caused to combine coerce, if it is improper to utilize, the Soil degradation such as Pedotransfer function and flooded stain can be caused to topic, polluted source, and a series of impact is seriously brought on agricultural environment and the ecosystem.Therefore, research technique of desalinating saline water is accelerated and to carry out application imperative.Traditional brackish water desalination mode mainly contains embrane method and Re Fa, and embrane method mainly contains reverse osmosis, nanofiltration, electrodialysis etc.Reverse osmosis and the current Application comparison of nanofiltration are extensive, for reverse osmosis, its treatment process be brackish water successively by mechanical filter and cartridge filter, then enter reverse osmosis unit and desalinate.These two kinds of technological processs all also exist a following difficult problem: one be the ratio of desalinization of reverse osmosis and nanofiltration is certain, cannot realize the conversion of different raw water quality, different water outlet requirement in same set of system, two is that the method for reverse osmosis and nanofiltration not easily meets same brackish water desalination system and meets the requirement of Different Crop irrigation water.From current technical standpoint, reverse osmosis and nanofiltration are all difficult to solve this two kinds of contradictions.If irrigated to process brackish water not in place, the growth of farm crop can be affected, bring huge financial loss to vast farmers.
Broad irrigation, traditional fertilization and the mode of spraying insecticide are one of current topmost agricultural problems of China, and main manifestations is: water, fertilizer, agricultural chemicals utilization ratio are not high, waste time and energy.According to statistics, the effective rate of utilization of broad irrigation only has 30-40%, and indivedual province is lower, metals run out, leaks, the phenomenon that seeps water is more serious.The loss of a large amount of fertilizer, causes the eutrophication of some areas groundwater pollution and rivers and lakes, causes extreme influence to environment.And pesticide spraying aspect, substantially still traditional manual operation, in fact, the agricultural chemicals sprayed away only has small part can arrive on the target of control.Poor efficiency in Pesticide use, not only wastes a large amount of agricultural chemicals, also makes a large amount of agricultural chemicals be lost in non-target environment, causes person poultry poisoning, environmental pollution.
The effective rate of utilization of how to improve agricultural irrigation, apply fertilizer, spraying insecticide, reduces the pollution to environment, becomes modern agriculture science problem demanding prompt solution, also constitutes the Main Topics of various applicability technology in 21 century.
Summary of the invention
Technical problem to be solved by this invention is the defect existed for prior art, there is provided a kind of agricultural brackish water Asia desalination process irrigation system integrated with water-fertilizer-pesticide, desalination in various degree can not only be realized, produce the water of different saltiness, to meet the demand of different crops, carry out water-fertilizer-pesticide integration to irrigate farm crop, cash crop simultaneously, the waste of fertilizer can be reduced, reduce labour intensity.
A kind of agricultural brackish water Asia desalination process irrigation system integrated with water-fertilizer-pesticide, comprises former water pot, electrodialysis unit inlet channel, electrodialysis brackish water treating device, electrodialysis unit outlet conduit, liquid storage tank, liquid storage tank outlet conduit, molten fertile tank, drug dissolving tank, fertilising pipeline, dispenser pipeline, mixed flow main pipeline, spray drop filling device, the pump housing, under meter, valve, pipeline.Described former water pot can regulate flow velocity and the pressure of extracting water from former well out, plays a protective role to follow-up equipment.All Water level controller is housed in former water pot and liquid storage tank, automatically can regulates the height of water level.
Described electrodialysis brackish water treating device utilizes electrodialytic method to carry out desalination process to brackish water, can according to the needs of different crops, from main control aqueous concentration.
Described liquid storage tank is connected with electrodialysis brackish water treating device by electrodialysis unit outlet conduit, electrodialytic water outlet is stored in liquid storage tank for subsequent use.
Described molten fertile tank is in order to a certain proportion of fertilizer solution needed for splendid attire farm crop, drug dissolving tank is in order to a certain proportion of liquid needed for splendid attire farm crop, at the bottom of molten fertile tank and drug dissolving tank tank, all stirrer is housed, the dissolving of acceleration fertilizer, agricultural chemicals also can keep the even of fertilizer liquid.
Described under meter is respectively used to the uninterrupted regulating liquid storage tank outlet conduit, fertilising pipeline, dispenser pipeline, according to the needs of concrete farm crop, with the ratio of this control irrigation process Zhong Shui, fertilizer, medicine.
Described fertilising pipeline, dispenser pipeline, liquid storage tank outlet conduit are all equipped with the pump housing, under meter, valve.
The invention has the advantages that: the present invention is reasonable in design, convenient, saving of labor; According to the demand of different crops, the salts contg of handled brackish water can be changed flexibly; Also traditional irrigation, fertilising can be avoided, the negative impact of spraying insecticide, practical; Cost is low.
