Description
Technical field
The sewage-treatment plant relating to field of Environment Protection of the present utility model, a kind of centrifugal sewage-treatment plant.
Background technology
Modern method of wastewater treatment is mainly divided into physical treatment process, method of chemical treatment and biological treatment three class.Physical treatment process is separated by physical action, reclaim the waste water logos of the pollutant in suspended state do not understood in waste water, and gravitational separation process, centrifugal separation and sieving can be divided into retain method etc.The processing unit belonging to gravitational separation process has: precipitation, float (air supporting) etc., the treatment facility of corresponding use is setting pot, sedimentation basin, oil interceptor, gas pond and auxiliary equipment thereof etc.Conventional centrifuge has filtering centrifuge (to utilize filter medium to realize solid-liquor separation, be applicable to the suspension being greater than 0.01 millimeter containing granularity), sedimentation centrifuge (utilizes the sedimentation principle of stratification to realize solid-liquor separation, be applicable to particle small or can the suspension of compression), when using centrifuge to carry out the mud-water separation of mud, by pump by the sewage suction centrifuge in cesspool, due to the precipitation of mud, be difficult to solid sludges to suck together in centrifugal pump.
Summary of the invention
The purpose of the present utility model overcomes the deficiencies in the prior art, provides improving one's methods in a kind of sewage disposal, and by installing bubbling device additional at sewage suction inlet, when sewage is sucked, muddy water sucks simultaneously.
The utility model is achieved through the following technical solutions:
A kind of centrifugal sewage-treatment plant, comprise cesspool, desliming centrifuge and suction pump, treatment sewage deposited by cesspool, sewage in cesspool is sucked desliming centrifuge by pipeline by suction pump, sewage is carried out being separated of water and mud by desliming centrifuge, it is characterized in that: around the suction pump water sucking mouth of cesspool, be provided with bubbling Rolling device, desliming centrifuge is centrifugal isolating construction, the water inlet of desliming centrifuge is connected with suction pump delivery port by pipeline, the suction hose of suction pump inserts cesspool, filtering grid and frequency conversion Pulp pump is provided with between suction pump and desliming centrifuge, frequency conversion Pulp pump connects desliming centrifuge by filtering grid, frequency conversion Pulp pump is also connected with frequency converter, water after separation is discharged by drainpipe by the discharge outlet of sludge separator, establish in drainpipe and water baffle plate was housed, filter pulp and filter, bubbling device is installed additional at sewage suction inlet, when sewage is sucked, muddy water sucks simultaneously, do further optimization to technique scheme, the pipeline of suction delivery side of pump is provided with the non-return valve with sideboard in, avoids muddy water to flow backwards, do further optimization to technique scheme, described filtering grid side is with cleanout, do further optimization to technique scheme, described bubbling Rolling device has independently controls gas system, and bubbling Rolling device comprises bubbling device, tracheae and compressed gas source, do further optimization to technique scheme, described bubbling device is hollow tube, and one end is closed, and one end is connected with tracheae, and body side is provided with several through hole.
The utility model has following beneficial effect:
1. purification efficiency is high;
2. cost is low, implements easily.
Accompanying drawing explanation
Fig. 1 is centrifugal sewage-treatment plant structure principle chart.
In figure: desliming centrifuge 1, suction pump 2, bubbling device 3, cesspool 4, filter grid grid 5, water inlet pipe 6, suction hose 7 and discharge outlet 8.
Detailed description of the invention
Below in conjunction with accompanying drawing, content of the present utility model is described further:
As shown be centrifugal sewage-treatment plant structure principle chart, comprise desliming centrifuge 1, suction pump 2, bubbling device 3, cesspool 4, filter grid grid 5, water inlet pipe 6, suction hose 7 and discharge outlet 8.
This device is the sewage-treatment plant adopting centrifugal structure, being separated of mud and water is carried out what suck containing the sewage of a large amount of mud by centrifuge, sewage storage is in cesspool, by suction pump, sewage is squeezed in centrifuge from cesspool by pipeline, suction pump is in the suction process of sewage, due to the precipitation of mud, solid sludges is difficult to suck together in centrifuge, for solving the problem, near the suction line of cesspool, bubbling device is set, bubbling device comprises tracheae and compressed gas source, bubbling device is hollow tube, one end is closed, one end is connected with tracheae, body side is provided with several through hole, sewage bubbling is made to roll after passing into compressed air, enter centrifuge by suction pump after sewage and mud mix and carry out mud-water separation, by installing bubbling device additional, improve separative efficiency.
