Abstract
The invention relates to a method for recycling facility farmland irrigation water through land treatment. The method comprises the following step: transforming facility farmland, wherein the transformed farmland comprises an upper layer of soil, a middle layer of quartz sand, a water collection tank, a perforated plate and a lift pump, wherein the middle layer of quartz sand is arranged under the upper layer of soil, the water collection tank is arranged under the quartz sand, the perforated plate used for stopping the quartz sand from dropping is arranged in an upper opening in the water collection tank, the lift pump placed in the water collection tank is used for pumping water into a biological unit on the ground through a return pipe, the pumped water is treated with the biological unit, the treated water is drained into the facility farmland under the control of an irrigation valve, the drained water is filtered through the soil layer and the quartz sand layer, and the filtered water returns to the water collection tank, so that the irrigation water can be recycled through land treatment. Through the adoption of the method, the reuse rate of the agricultural irrigation water is improved, the energy is saved, the emission is reduced, and the current contradiction between water resource supply and demand in China is relieved.
Description
Technical field
The invention belongs to technical field of sewage, especially a kind of land treatment systems circulation means of facility farmland irrigation water.
Background technology
The development of agricultural adds the demand to irrigation water use, has increased the weight of current serious water shortage situation.The farmland irrigating water of northern area is based on underground water, and the excess exploitation of underground water causes a series of consequence of subsurface degradation, is thus necessary very much the contradiction solving agricultural water, thus keeps the Sustainable development of agricultural.
Utilize soil retaining and microbiological deterioration Pollutants in Wastewater, and follow-up quartz sand filtration effect, dual intensive treatment is adopted to the pollutent in waste water, the index of correlation of waste water is made to meet the requirement of " agricultural irrigation water quality standard " (GB5084-2005), thus realize the cyclically utilizing of farmland irrigation water, be the direction that relevant technical personnel make great efforts always.By retrieval, do not find the patent documentation of associated viscera at present.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, and propose a kind of land treatment systems circulation means of facility farmland irrigation water.
The present invention solves its technical problem and takes following technical scheme to realize:
A land treatment systems circulation means for facility farmland irrigation water, method steps is as follows:
Facility farmland is transformed, transformation farmland comprise the middle level quartz sand below upper layer of soil, pedosphere, the water collecting basin below quartz sand, water collecting basin upper shed place be mounted with stop quartz sand fall porous plate, in water collecting basin, be placed with lift pump, lift pump by return water pipe by water pumpback to ground biological unit, water after biological unit process enters Tanaka by irrigation valve gate control, the water entering Tanaka, by getting back in water collecting basin after the filtration of pedosphere and quartz sand layer, forms the land treatment systems circulation of irrigation water.
And described edaphic thickness is 1 meter, the thickness of middle level quartz sand is 0.5 meter.
And described water collecting basin is the cement pit of quartz sand bottom.
And described biological unit is membrane bioreactor unit, the process of membrane bioreactor unit to irrigation water specifically comprises:
1. irrigation water enters membrane bioreactor cell processing, and under pneumatic blending condition, irrigation water fully mixes with the active sludge in reactor, and sludge concentration controls at 4-8g/L;
2. control irrigation current are 4-8h through the time of membrane bioreactor unit, and the membrane module in reactor adopts hollow fiber form or flat-plate ultrafiltration membrane, and aeration rate and flooding quantity volume ratio are 15:1.
And, describedly enter Tanaka by irrigation valve gate control and be: by the lower infiltration rate rate of irrigation water in irrigation valve gate control soil filtration procedure.
And the lower infiltration rate rate of described irrigation water is concrete, for vegetable crop, under ooze rate-controlling at 0.5-1.0M/ days; For food crop, under ooze rate-controlling at 1-2M/ days; For cash crop, under ooze rate-controlling at 2-5M/ days.
Advantage of the present invention and positively effect are:
1, the recycle of agricultural irrigation waste water can be realized;
2, improve the reclamation rate of agricultural irrigation water, achieve energy-saving and emission-reduction;
3, waste water recycling slow down the contradiction of current China water resources supply and demand.
