Detailed Description

To better illustrate the objects, aspects and advantages of the present invention, the present invention will be further described with reference to specific embodiments. This invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of the utility model to those skilled in the art, and the present invention will only be defined by the appended claims.

As shown in figure 1, the utility model provides a microorganism-enhanced ecological pond suitable for rural domestic sewage treatment, which consists of a microorganism aerobic pond 1, a microorganism facultative tank 2, a sedimentation tank 3 and an artificial wet area 4 which are sequentially communicated in series. Domestic sewage is injected from the water surface of the microorganism aerobic tank 1, sequentially passes through the microorganism aerobic tank 1, the microorganism facultative tank 2, the sedimentation tank 3 and the artificial wet area 4, and is discharged from the water surface of the artificial wet area 4.

The ecological pond is arranged in a riverway or a marshland or an idle pond around villages, makes full use of surrounding miscellaneous lands, and has the characteristic of beautifying the environment.

Furthermore, a first separation wall 5 is arranged between the microorganism aerobic tank 1 and the microorganism facultative tank 2, and a first water outlet 51 is arranged at the bottom of the first separation wall 5, so that the sewage in the microorganism aerobic tank 1 flows into the microorganism facultative tank 2 through the first water outlet 51. The water surface height of the microorganism aerobic tank is higher than that of the microorganism facultative tank.

A second separation wall 6 is arranged between the microorganism facultative tank 2 and the sedimentation tank 3, and the sewage in the microorganism facultative tank 2 flows into the sedimentation tank 3 through water surface overflow.

A third separation wall 7 is arranged between the sedimentation tank 3 and the artificial wet area 4, and a second water outlet 71 is arranged on the third separation wall 7, so that the sewage in the sedimentation tank 3 flows into the artificial wet area 4 through the second water outlet 71.

Furthermore, the bottom of the artificial wet area 4 is arranged from high to low along the water flow direction, the highest position of the bottom of the artificial wet area 4 is higher than the bottom of the sedimentation tank 3, and the second water outlet 71 is arranged at the highest position of the bottom of the artificial wet area 4 on the third partition wall 7.

The water surface elevations of the microorganism facultative tank 2 and the sedimentation tank 3 are lower than that of the artificial wet area 4.

Furthermore, the microorganism aerobic tank 1 comprises a solar micropore aeration system 8 and suspended biological fillers 9, wherein the solar micropore aeration system 8 comprises an aeration pipeline and an aeration disc, and the aeration pipeline and the aeration disc are distributed in the whole area. By adding the high-efficiency aerobic composite microbial agent and the suspended biological filler 9 into the microbial aerobic tank 1, the pollutant removal rate of the microbial aerobic tank 1 can be effectively increased.

Furthermore, the solar energy micropore aeration systems 8 are arranged in the microorganism facultative tank 2 in different areas to form a facultative environment, facultative microorganisms are added to promote the removal of organic matters, total nitrogen and total phosphorus, and the facultative area can not only remove common organic pollutants, but also effectively remove nutrient substances such as nitrogen and phosphorus and certain organic pollutants which are difficult to degrade, thereby further improving the water quality.

Furthermore, the sedimentation tank 3 has a sedimentation effect, reduces the concentration of suspended matters and prevents the blockage of the artificial wetland system.

Furthermore, the artificial wet area 4 mainly includes filler (cobblestones, crushed stones, etc.) and aquatic plants (emergent aquatic plants such as reeds). On one hand, emergent aquatic plants absorb nutrient elements such as nitrogen, phosphorus and the like for self growth and propagation; on the other hand, a large amount of biological membranes are formed by developed root systems of emergent aquatic plants, and the plants can deliver oxygen to the biological membranes through the root ends, so that the purification of the microorganisms to pollutants is promoted. Through the filtering and purifying effect of the artificial wetland, pollutants such as suspended matters, organic matters, nitrogen and phosphorus in the sewage are deeply purified, the water quality basically can reach the standard of class V of surface water, and the main index can reach the standard of class IV of surface water.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the utility model.
