The centrifugal sewage treatment device comprises a sewage tank, a desliming centrifugal machine and a suction pump, wherein the sewage tank is used for storing sewage to be treated; the suction pump is used for sucking the sewage in the sewage tank into the desliming centrifugal machine by a pipeline; the desliming centrifugal machine is used for separating water and sludge of the sewage; a bubbling overturning device is arranged around a water suction hole of the suction pump of the sewage tank; the desliming centrifugal machine has a centrifugal separation structure; a water inlet of the desliming centrifugal machine is connected with a water outlet of the suction pump by a pipeline; a water suction pipe of the suction pump is inserted into the sewage tank; a filter grille and a variable frequency slurry pump are arranged between the suction pump and the desliming centrifugal machine; the variable frequency slurry pump is connected with the desliming centrifugal machine by the filter grille, and is also connected with a frequency converter; a drainage hole of a sludge separator is used for discharging the separated water by a drainage pipe; the drainage pipe is internally provided with a water through baffle, filtering cotton and a filter. The centrifugal sewage treatment device has the advantages of being high in purification efficiency, low in cost, easy to implement, etc.
Description
Technical field
The sewage-treatment plant relating to field of Environment Protection of the present invention's invention, 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 object of the present invention's invention overcomes the deficiencies in the prior art, and provide improving one's methods in a kind of sewage disposal, by installing bubbling device additional at sewage suction inlet, when sewage is sucked, muddy water sucks simultaneously.
The present invention is achieved by 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 present invention has following beneficial effect:
