Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the utility model discloses sewage treatment plant, as shown in figure 1, including reservoir 1, the room of stewing 2, mud-water separation room 3 and reacting chamber 4. Sewage is pumped into the liquid storage tank 1 for temporary storage, enters the standing chamber 2 through the communication pipeline, most of oil is located above water after standing for a period of time, and then the oil is removed through a conventional means, such as a conventional air floatation device and the like, which is not described in detail herein and can also be removed manually. After oil removal, the sludge enters a sludge-water separation chamber 3 to deposit sludge and discharge water, and finally organic matters are removed and the water quality is purified through a reaction chamber 4.

Specifically, a controller 21, a liquid level sensor 22 and an alarm 23 are arranged on the standing chamber 2, the liquid level sensor 22 and the alarm 23 are both in communication connection with the controller 21, and the liquid level sensor 22 is located at the top of the standing chamber 1. The liquid level is detected by the liquid level sensor 22, the detected information is fed back to the controller 21, and after the liquid level reaches the designated liquid level, the controller 21 controls the alarm 23 to start alarming, so that an operator closes control valves on pipelines of the liquid storage tank 1 and the standing chamber 2 and stops liquid feeding.

The mud-water separation chamber 3 is sequentially provided with an effluent weir 31, a collecting tank 32, a mud-water separator baffle 33 and a mud bucket 34 from top to bottom, the effluent weir is circular, after sewage with oil stain removed enters the mud-water separation chamber 3 from a water inlet with a certain tangent angle, large-particle sludge moves downwards under the action of centrifugal force and gravity, clear water rises, and smaller particle sludge is settled at the mud-water separator baffle 33, so that chemical agents and power are not needed, rapid and efficient settling is realized, the settled sludge is collected, and the sludge is discharged out of the mud-water separation device through a sludge discharge port of the mud bucket; the supernatant overflows from the water outlet weir 31, is collected by the collecting tank and then is discharged from the water outlet.

Preferably, the mud-water separator baffle uses the principle of shallow sedimentation, the inclination is 60 degrees, and two adjacent plates are oppositely arranged.

The utility model discloses the mud-water separation room has energy-conservingly, need not power, need not to use the medicament to carry out the advantage that deposits.

Sewage can evenly spray on the filler in the reacting chamber through the shower nozzle at last, with pack the surperficial biomembrane contact, be favorable to getting rid of organic matter, it is concrete, 4 from the top down rubble 41 and the fine sand 42 that fill in proper order of reacting chamber make the filter material grained layer be big-end-up's state, the great rubble 41 of particle diameter is as packing, because of having great porosity between the rubble, can prevent effectively that the packing layer from blockking up, the continuous aeration in packing bottom, therefore, compare with constructed wetland, the filter material is difficult for blockking up, it is more convenient to manage. Moreover, when the sewage is fed from the upper part, the sewage firstly encounters a filter material with larger particles, the filtering action can be deeply penetrated into the filtering layer to generate the penetration filtering action, larger particle impurities in the water are removed, and a part of sludge and small suspended matters can be intercepted by the smaller particle fine sand on the lower layer, so that the function of ensuring the water quality of the effluent is achieved; aeration systems 44 comprises 5 aeration pipes that are parallel to each other, and the interval is provided with a plurality of round holes on the aeration pipe, and the round hole is faced the top and is set up, and the aeration pipe is located the reacting chamber bottom, from lower up continuous aeration, leads to the interior lower floor dissolved oxygen of device more, and upper dissolved oxygen is less, and the aeration is favorable to preventing the jam of filler simultaneously.

Still be provided with bearing board 43 between fine sand and aeration system, be provided with a plurality of through-holes on the bearing board 43, the bearing board is used for bearing the pressure that the rubble brought and avoids causing the harm to the aeration pipe of below on the one hand, and on the other hand through-hole on the bearing board can make the gas that comes out in the aeration pipe evenly contact with the sewage of top, does benefit to the processing of sewage.

Preferably, the sewage treatment device of the present invention is further provided with a drain pipe 45 below the aeration system 44, and the drain pipe 45 is perpendicular to the arrangement position of the aeration pipe.
