Description
Technical field
The present invention relates to a kind of sewage-treatment plant inversely filtered, belong to field of sewage treatment equipment.
Background technology
With our industrialization and urbanization aggravation develop, in recent years between, the water pollution phenomenon of China becomes more next
It is more more serious, if the water source after these pollutions is directly discharged in rivers, it will rivers directly are caused with serious pollution.Cause
This, is all generally to be concentrated to be drained to sewage treatment plant by pipeline, can just be emitted into after treatment in rivers.
Flocculent precipitation is sewage water treatment method commonly used in the prior art, delivers flocculant in flocculent precipitation of the prior art
When, flowing to for the direction of motion of flocculant and sewage is identical, and the dissolution velocity of flocculant and sewage is slow, causes the flocculation of sewage
Processing speed is slower, have impact on the speed in cesspool.
The content of the invention
The goal of the invention of the present invention is：Exist for prior art：" when delivering flocculant in flocculent precipitation, wadding
Flowing to for the direction of motion of solidifying agent and sewage is identical, and the dissolution velocity of flocculant and sewage is slow, causes the flocculation treatment of sewage
Speed is slower, have impact on the speed in cesspool " the problem of there is provided a kind of sewage-treatment plant inversely filtered.
In order to solve the above technical problems, the present invention is adopted the technical scheme that, a kind of sewage-treatment plant inversely filtered,
Including flocculant conduit, shell and sewage water inlet pipe；The first filter screen, the second filter screen are from top to bottom disposed with the shell

Lower section and sewage water inlet pipe it is open-ended towards enclosure bottom face；Set between first filter screen, the second filter screen
There is middle barrier, sludge baffle plate is provided between the second filter screen and the 3rd filter screen；Some inside are provided with the middle barrier
It is provided with space below mozzle, inner guiding pipe UNICOM middle barrier top, middle barrier, inner guiding pipe unidirectional
Some through holes are provided with valve, sludge baffle plate；The flocculant conduit passes through the top end face and the first filter screen of shell, and flocculant is led
Pipe is rotated with housing top end face and is connected, and the lower end of flocculant conduit is arranged at；Sewage is provided with the top end face of the shell to lead
The inside UNICOM of outlet pipe, sewage delivery line and shell.
In the technical scheme of the application, sewage enters bottom in shell by sewage water inlet pipe, with sewage in shell
Sewage in the increase of inlet, shell is flowed from bottom in shell to shell internal upper part.Flocculant conduit is arranged at shell
Top end face, flocculant is injected and the lower flow into shell by flocculant conduit from shell upper.It is dirty by such mode
The flow direction of water and flocculant is on the contrary, so the molecular friction of flocculant and sewage is increased, and flocculant is more prone to be dissolved in dirt
In water, the dissolution velocity of flocculant is accelerated, and then accelerates the flocculation reaction speed of sewage.
In the technical scheme of the application, sewage enters to move upwards in shell, during sewage is moved upwards first
The dirt by sludge baffle plate is reduced by the impurity that particle diameter in the 3rd strainer filtering sewage is larger, and by sludge baffle plate
Sludge and floccule in the flow velocity of water so that sludge is precipitated, the further filter sewage of the second filter screen.Sewage passes through middle part
The check valve that the flocculant that inner guiding pipe on baffle plate enters flocculant conduit is delivered in region, inner guiding pipe prevents wadding
Floccule after solidifying enters the lower section of middle barrier.
Optimization, the above-mentioned sewage-treatment plant inversely filtered, the part that the flocculant conduit is arranged in shell connects
It is connected to some auxiliary flocculation pipes, auxiliary flocculation pipe and flocculant conduit UNICOM.
Optimization, the above-mentioned sewage-treatment plant inversely filtered is open-ended towards housing top end face.
Auxiliary flocculation pipe enables flocculant to deliver the region from flocculant catheter surface farther out, increase sewage and wadding
The uniformity of solidifying agent mixing.Aid in the open-ended towards housing top end face of flocculation pipe, so that flocculant is leaving auxiliary
The region farther from flocculant catheter surface can be flowed to after flocculation pipe.
Optimization, the above-mentioned sewage-treatment plant inversely filtered, the sludge baffle plate is conical baffle, sludge baffle plate
Inner bottom end face of the conical bottom end face towards shell.
Optimize, the above-mentioned sewage-treatment plant inversely filtered, sludge baffle plate is connected with the through hole of the sludge baffle plate
Conduit, sludge baffle plate conduit is arranged at the upper surface of sludge baffle plate.
Optimization, the above-mentioned sewage-treatment plant inversely filtered, the sewage water inlet pipe is located at one end connection in shell
There is horn-like conduit mouth.
Optimize, the above-mentioned sewage-treatment plant inversely filtered, downcomer baffle, conduit are provided with below the conduit mouth
Baffle plate is horn-like, the inner bottom end face of the loudspeaker opening of downcomer baffle towards shell.
Horn-like conduit mouth is added in the technical scheme of the application, impact of the sewage for shell bottom face is reduced,
Prevent the impact because of sewage so that the sludge for being deposited in shell bottom is mixed with sewage again.Downcomer baffle further reduces sewage
For the impulsive force of shell bottom face.
Optimization, the above-mentioned sewage-treatment plant inversely filtered, the bottom face of the shell is cone, the bottom of shell
It is connected with face on sludge conduit, sludge conduit and is provided with stop valve.
The bottom face of shell is set into cone can more facilitate the sludge stream of precipitation to go out shell.
The advantage of the invention is that the drawbacks of it can overcome prior art, reasonable in design is novel.The technology of the application
In scheme, sewage enters bottom in shell by sewage water inlet pipe, with the increase of sewage inlet in shell, in shell
Sewage is flowed from bottom in shell to shell internal upper part.Flocculant conduit is arranged at the top end face of shell, and flocculant passes through flocculation
Agent conduit is injected and the lower flow into shell from shell upper.By such mode, the flow direction of sewage and flocculant
On the contrary, so the molecular friction of flocculant and sewage is increased, flocculant is more prone to be dissolved in sewage, accelerates the molten of flocculant
Speed is solved, and then accelerates the flocculation reaction speed of sewage.
