Description
Technical field
The present invention relates to field of farm irrigation, more specifically to a kind of field irrigation heavy metals removal equipment.
Background technology
With the continuous improvement of industrial expansion and urbanization degree, water resource day is becoming tight, and there is nearly 80% city in the whole nation
Water shortage, the north is particularly acute, and the annual lack of water total amount in the whole nation is up to 120,000,000,000 m3, 200,000,000,000 yuan of annual therefore influence industrial output value with
On.The scarcity of water resource, makes sewage turn into the important component of irrigation water.At present, wastewater treatment in China rate is low, irrigation water
Matter severe overweight.The plurality of heavy metal element contained in sewage can be enriched with and scattered in soil, and have difficult degradation, toxicity
By force, with build-up effect the characteristics of.The problem of this makes heavy metal pollution of soil becomes increasingly conspicuous.Research has shown that, heavy metal element amount
More than certain boundary, wheat, paddy rice, the growth of seeding corn and other crops will be suppressed, the underproduction is caused.And most crops are to a huge sum of money
The uptake and accumulation of category is related in conspicuousness to the concentration of heavy metal in soil.Heavy metal can endanger people by various food chain forms
Body health.Famous " Itai-itai diseases " event of Japan precisely due to the waste water irrigation farmland of smeltery is used for a long time, cause soil and
Cadmium content increase in rice, and people has eaten what this rice was caused.Soil is an important step in food chain, is environment
One of key element, therefore the heavy metal pollution problem that research sewage irrigation is brought promotes social economy to hold to preserving the ecological environment
Supervention exhibition is significant.
The content of the invention
1. the technical problem to be solved
For problems of the prior art, set it is an object of the invention to provide a kind of field irrigation with heavy metals removal
Standby, it can be realized is carried out after two-stage flocculation by heavy metal, tiny flocculation and bubble formation flocculation bubble heel row
Go out, the effect of removing heavy metals is gone in lifting.

Side is connected with drainpipe, irrigation water is extracted to hanging in bucket by water pump, while being trapped by filling pipe to addition in bucket is hung
Agent, in puddler and in the presence of smashing blade, crushes the big solid particle in irrigation water, trapping agent is used with irrigating
Water is sufficiently mixed, and carries out one-level heavy metal flocculation, is mixed the irrigation water of trapping agent from bung outflow is hung, is dissipated by rotating vane
Cloth is to standing in bucket, and flocculation, trapping agent, other solid particles fall in standing bucket, and other solid particles sink to standing
Bottom of the barrel, trapping agent continues to produce flocculation with the heavy metal effect in irrigation water, carries out two grades of heavy metal flocculations, bubble
The bubble rising that rod is produced is produced, the bubble in bucket is stood with flocculation formation flocculation bubble, the bubble that flocculates rises to drainage
Flowed out at mouthful, collected and focused on by connecting tube, the content of beary metal in irrigation water is greatly lowered, hence it is evident that
Crop yield is lifted, the harm to human body is reduced.
Preferably, the height of the rotating vane, which exceedes, stands bucket, and throw away irrigation water during rotating vane rotation
Distance no more than stand bucket draining hole, enable the irrigation water of mixing trapping agent evenly spread to standing bucket in, increase
Big flocculation and with bubble collision probability.
Preferably, screening net is connected with the notch of the water receiving tank, the aperture of the screen pack is 1-5cm, screens net
