Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
The utility model announces a kind of agricultural irrigation water desalination method, comprises the following steps:
Step 1: draw water to metre filter by water pump from water source, obtain filtered water;
Step 2 a: part for filtered water obtains desalination water at atmospheric pressure through reverse osmosis unit, then enters water-water jet; Another part of filtered water directly enters water-water jet;
Step 3: described filtered water mixes to set ratio with described desalination water at atmospheric pressure by water-water jet; Water mixing proportion need according to the situation of waterhead area water quality, with " agricultural irrigation water quality standard " for instructing, the indices of mixed water is made all to meet the water quality demand of irrigation water, if total salt quantity in water is 1500mg/L, muriate is 400mg/L, the standard that 1000mg/L and muriate be less than 350mg/L is less than according to total salt quantity in irrigation water quality standard, according to the index of total salt quantity, the ratio of salt water and the rear fresh water of process is less than 2:1 and can meets the demands, and according to muriate index, mixing salt water and the rear fresh water ratio of process should be less than 7:1.As can be seen here, when water mixing proportion meets total salt quantity index, muriate ratio is also met.Therefore, when determining water mixing proportion, should meet the demands with whole index and being as the criterion, obtaining irrigation water.
Described step 2 specifically comprises the following steps:
