When temperature raises, withered death phenomenon in watermifoil, and treatment effect is not good.
Content of the invention
The purpose of the present invention is to overcome drawbacks described above, provides a kind of utilization watermifoil to process the device of Pig raising wastewater.
Technical scheme：A kind of utilization watermifoil processes the device of Pig raising wastewater, including adjusting sedimentation tank, described
Adjust sedimentation tank and be sequentially communicated one-level matrix pool, secondary matrix pond and three-level matrix pool, described three-level matrix pool is sequentially communicated down
Row vertical current one-level watermifoil artificial swamp, surface stream two grades of watermifoil artificial swamps, upward vertical flow three-level watermifoils are artificial
Wetland, surface stream level Four watermifoil artificial swamp, described two grades, level Four watermifoil artificial swamp surface be wavy, Vulpes at different levels
Tail algae artificial swamp all plants watermifoil, puts into Caulis et Folium Oryzae in matrix pool at different levels.
Before watermifoil artificial swamp, setting adjusts sedimentation tank, a large amount of SS in precipitable removal Pig raising wastewater, and is easy to
Adjust suitable pH to improve watermifoil artificial wetland treatment efficiency.Matrix pool can filter the SS in Pig raising wastewater further,
And play purification, it is lowered into the pollutant burden of Pig raising wastewater during artificial swamp.Vertical current flows watermifoil people with surface
The setting that work wetland combines, and two grades, the setting of level Four watermifoil artificial swamp surface wave wave-like, strengthen the tortuosity of current,
Improve watermifoil artificial wetland treatment efficiency.
Preferably, described one-level, two grades, three-level, level Four watermifoil artificial swamp plantation watermifoil above be equipped with anti-
Shine net, when summer temp is higher, can effectively prevent watermifoil withered death.
Preferably, described one-level, two grades, three-level, level Four watermifoil artificial swamp be equipped with fixed mesh, watermifoil is planted
In described fixed mesh, described fixed mesh is no less than one layer.Multilamellar fixed mesh is arranged, and can prevent watermifoil by current
Break up, lodge, thus improving treatment effeciency；When accumulating more plant residue, branch and leaf in watermifoil artificial swamp, can entirely be consolidated
Determine grid to lift, play salvaging plant residue, branch and leaf, prevent from blocking, improve the effect of wetland variation efficiency.
Advantage of the present invention：
1st, adjust the setting of sedimentation tank, a large amount of SS in precipitable removal Pig raising wastewater, and be easy to adjust suitable pH to carry
High watermifoil artificial wetland treatment efficiency.Matrix pool can filter the SS in Pig raising wastewater further, and plays purification, fall
The pollutant burden of Pig raising wastewater during low entrance artificial swamp.Vertical current flows, with surface, the setting that watermifoil artificial swamp is combined,
And two grades, the setting of level Four watermifoil artificial swamp surface wave wave-like, strengthen the tortuosity of current, improve watermifoil artificial swamp
Treatment effeciency.
2nd, the setting of multilamellar fixed mesh, can prevent watermifoil from being broken up by current, lodging, thus improving treatment effeciency；
When accumulating more plant residue, branch and leaf in watermifoil artificial swamp, whole fixed mesh can be lifted, play salvaging plant residual
Body, branch and leaf, prevent from blocking, improve the effect of wetland variation efficiency.
3rd, the setting of sun-proof net, can effectively prevent the withered death of watermifoil during summer high temperature.
