Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a rural sewage treatment plant, including the device main part, device main part top surface has set firmly into fill 1, it is equipped with grid tray A2 to advance 1 middle part of fighting, device main part upper portion has set firmly baffle 3, baffle 3 is cut apart into two parts with device main part upper portion, the left side is catch basin 4, the right side is

oxygen deficiency pond

5, 3 middle parts of baffle and 4 bottom surfaces of catch basin have set firmly

water service pipe

6, 5 lateral walls in oxygen deficiency pond have set firmly ventilation pipe B501, device main part middle part is good oxygen pond 8, good oxygen pond 8 internal fixation has two netted baffles 801, be equipped with waterwheel 802 between two

netted baffles

801, 8 top surface edges in good oxygen pond have set firmly play weir 9, device main part lower part is filtering pond 10.

Specifically, the top surface of the anoxic pond 5, the top surface of the collecting pond 4 and the side wall of the collecting pond 4 are all fixedly provided with a ventilation pipe A7, so that the ventilation of the device is facilitated.

Furthermore, a plurality of suspended fillers 803 are arranged in the aerobic tank 8, and the suspended fillers 803 are well mixed with water under the aeration condition; if the environment is anaerobic, a fluidized state is formed by the stirrer; microorganisms grow inside and outside the filler, and then form a stable biological film; under the action of aeration or stirring, moving bed biological membranes are arranged in the reactor space, so that organic substances in the treated wastewater are in back-and-forth contact with the biological membranes on the suspended fillers 803, and the contents of COD, nitrogen and phosphorus in the wastewater are reduced.

Furthermore, the positions of the interior of the filter 10 and the upper part of the device main body relative to the water through pipe 6 in the middle of the baffle 3 are both provided with two grid plates B12 in a symmetrical structure, and the grid plates B12 are used for intercepting fillers, so that the loss of the fillers is avoided.

In addition, a triangular water outlet weir 11 is fixedly arranged at the upper part of the filter 10, anthracite 13 is accumulated at the middle part of the filter 10, spherical light ceramsite 14 is accumulated at the lower part of the filter 10, and the spherical light ceramsite 14 is used as a carrier, so that the number of microorganisms in the reaction tank is increased, and the total treatment efficiency is improved.

The working principle is as follows: the anoxic tank 5 is used for realizing denitrification reaction, the aerobic tank 8 is used for realizing nitrification reaction, wherein the oxygen supply adopts water outlet of a water collecting tank, the gravity of water flow enables a waterwheel 802 to rotate, so as to play a role of disturbing water body and achieve the purpose of disturbing oxygen supply, a ventilation pipe A7 is used for supplying oxygen in an auxiliary way through natural ventilation, then the aerobic tank 8 enters a biological filter 10 (an up-flow biological filter 10) through a water distribution device, anthracite 13 and spherical light ceramsite 14 are filled in the biological filter 10, sewage flows up from the bottom to the inside of the tank body through the first layer of filler, macromolecular pollutants can be intercepted by the spherical light ceramsite 14, then the sewage passes through the second layer of filler in an up-flow mode, the sewage passes through a filter material of the anthracite 13, microorganisms grow and breed on the surface to gradually form a layer of biological membrane, the biological membrane absorbs organic matters from the sewage for a long time to serve as a self nutrient source, the purpose of purifying sewage is achieved. Wherein, the oxygen supply in the filter 10 is realized by adopting natural ventilation. After the biofilm is formed, due to the growth and propagation of microorganisms, when the biofilm reaches a certain thickness, oxygen cannot enter the biofilm, and an anaerobic state is formed, so that the activity of the microorganisms in the biofilm begins to be reduced, and the adhesive force is weakened. The treated sewage can be utilized to wash from top to bottom, the water flow impacts the filler and then enters the pool body, and the biological membrane begins to fall slowly. After the falling of the water drops, a new biological film grows again, and the circulation is repeated. After passing through the biological membrane, the sewage can be purified and finally discharged.
