Description
Technical field
It is specifically that a kind of be lost in for South China's laterite causes river to suspend the present invention relates to technical field of sewage
The processing system of thing pollution is with processing method.
Background technology
South China of China has large area to be rich in iron, aluminum oxide, in acid red laterite area, such regional water and soil stream
Lose serious.According to fine jade, Guangdong, osmanthus, Hunan, Jiangxi, Fujian, E7Sheng (area) statistics up to 220,000 km2, and platform, Yunnan, expensive, river, Zhejiang, Wan Hongtuqu
Estimation also has 80,000 km2, therefore In Southwest China laterite area is lost in area up to 300,000 km2, than soil erosion for loess region area face
280,000 km of product2More than.The laterite being largely lost in finally is pooled in the river,lake and reservior of downstream, to the ecological work(of downstream river,lake and reservior
It can produce and have a strong impact on quality of water environment, such as：The laterite of loss has stronger adsorption capacity, is nutrient and other dirts
The important carrier of thing is contaminated, the pollutants such as various metals material, chemical fertilizer, agricultural chemicals is carried under one's arms, causes water pollution；The usual grain of laterite particle
Footpath is small, not free settling, water body is become muddy, influences attractive in appearance；In addition, laterite can also cause riverbed lifting, reservoir capacity to reduce,
Water-holding capacity declines, and integrally-regulated ability declines, influence flood control safety etc..
However, so far, having no that proposition is a kind of has actual operability, and significant to suspension laterite removal effect
Technical scheme.

80-150mg/L and 1.5~2.0mg/L；
2) current after dosing flow through dividing plate, river width is narrowed by dividing plate, flow rate of water flow increase, produce turbulent flow,
So that medicament is well mixed with river, left and right is caught by net and sweeps along suspension bed sediment to form flco monomer, quality increase；
3) current of confection are flowed through into aquatic plant zones, reduces flow velocity, and in the suction-operated of root system of plant
Under make flco monomer start sedimentation；
4) flco monomer and silt finally, are intercepted by littoral barrier under water, make flco monomer and silt heavy along littoral barrier
Drop in silt collecting tank, prevent flco with current migrated downstream；
5) undercurrent pump is opened at regular intervals, to exclude the flco in silt collecting tank.
Present invention processing South China's laterite is lost in the system and method for river suspended solid pollutant of causing, with having as follows
Beneficial effect：
1. by setting the flow velocity of iris type to increase area, making river width narrow, increase flow velocity, produce turbulent fluctuation, make medicament
It is well mixed；
2. the present invention sets water plant flocculation band and under water littoral barrier, two effects can be played, one is to reduce
Flow velocity, promotes sediment settlement, current is become limpid；Two be that can collect silt, it is to avoid causes underwater bed lifting, reservoir capacity
Reduce.
3. by setting immersible pump, being discharged into the silt of silt collecting tank, the effect for removing silt is reached.
