Description

Efficient Rural Sewage Purification Device

technical field

The utility model relates to a sewage treatment system, in particular to a high-efficiency rural sewage purification device.

Background technique

At present, due to the sewage formed by life and production, the damage to the water environment has reached an urgent moment of protection. Most of the existing traditional treatment methods for the domestic sewage and feces of people in rural areas and urban communities are anaerobic fermentation and sedimentation. It is necessary to build a leak-proof cement cesspit. The service life is not long, which often leads to leakage and affects the quality of groundwater. This existing treatment method cannot achieve beneficial effects such as solid-liquid separation, direct discharge of waste liquid, and secondary utilization of waste solids. In addition, in the existing sewage treatment system, fillers containing microorganisms are often used to purify water by hanging film, but this treatment method has obvious technical defects, that is, the survival of microorganisms has strict requirements on the ambient temperature. The installation must be distinguished by region. For example, some microbial treatment systems cannot be used in cold northern regions. In terms of time, winter in the south will also cause the death of microbial systems, which will affect the normal use of treatment equipment. How to design a full-time and geographically efficient rural sewage treatment system with simple construction, solid-liquid separation, waste-liquid direct discharge, and waste-solid secondary utilization has always been the object of research by those skilled in the art.

Chinese Invention Patent Application No. 201410294304.3 discloses a one-time injection molding septic tank, including a main body, and the main body is fastened by bolts into a whole by two half boxes. A septic tank partition and two septic tank partitions are arranged in the above-mentioned main body. A septic tank partition and two septic tank partitions form a two-compartment septic tank; a septic tank partition and the main body of the septic tank form a septic tank; two septic tank partitions A three-compartment septic tank is formed between the board and the main body of the septic tank. This three-compartment septic tank has no technical tips or solutions for direct discharge of waste liquid and full-time treatment.

Contents of the invention

The utility model provides a high-efficiency rural sewage purification device with simple construction, solid-liquid separation, direct discharge of waste liquid, wide application in space and area.

A high-efficiency rural sewage purification device, including a cylinder composed of coiled plates, the two ends of the cylinder are hermetically connected and respectively provided with end caps for the sewage pipe and the outlet pipe, and the inside of the cylinder is divided into three areas by two partitions, The three areas mentioned are anaerobic fermentation area, biochemical treatment area and sedimentation drainage area in sequence.

The anaerobic fermentation area includes a submerged elbow connected to the sewage pipe; the structure of the submerged elbow has changed the traditional three-compartment septic tank and other sewage treatment devices. The first compartment must be an aerobic zone connected to the atmosphere through the inlet. This kind of aerobic structure is not conducive to the generation of anaerobic fermentation environment. The utility model forms an anaerobic fermentation area in the cylinder area connected to the sewage pipe through the submerged water bend structure, and forms anaerobic fermentation through a closed anaerobic environment, which can be decomposed Protein organic matter, and produce methane, ammonia and other substances, to kill parasite eggs and germs for the first time.

The biochemical treatment area includes a chain-like packing that spirally winds a hollow telescopic rod. The body of the hollow telescopic rod is provided with air holes, and carbon tubes are embedded in the air holes. The porous structure of the carbon tubes is used to reproduce microorganisms in large quantities. Bacteria, the telescopic rod body with a hollow structure can not only be used as an oxygen source channel for aerobic bacteria such as complex flora, but also can be used as a channel for secondary addition of complex flora, which greatly improves the convenience of use. The chain-like packing not only prevents the premature failure of the packing caused by the entanglement between adjacent packings by spirally winding the hollow telescopic rod, but also the depth of the hollow telescopic rod is controllable, so that the water quality fluctuations of the incoming water are fully dispersed, and at the same time It is quickly reduced, thereby improving the system's ability to resist shock loads. The biochemical treatment area also includes a water collection pipe at the top of the cylinder and a water distribution pipe at the bottom of the cylinder. The heat absorbed and converted by the ground source heat pump is evenly dispersed into the heat pipe through the water distribution pipe, so as to maintain the treatment temperature in the biochemical treatment area, ensure the activity of the complex bacteria and a good reproductive state, and achieve the technical purpose of efficient sewage treatment. The ground source heat pump increases the treatment temperature in the biochemical treatment area without being limited by time and space, realizing the all-weather and all-regional characteristics of the scope of application of the utility model.

The chain filler is a mixture of polyvinyl chloride, bamboo fiber and elm bark powder, and the preferred weight percentage components are: 80-90% polyvinyl chloride, 5-10% bamboo fiber, and 5-10% elm bark powder. The elm bark powder has natural plant stickiness and can quickly realize film formation, which greatly improves the performance of clear water. The micropores formed by the corrosion of elm bark powder further increase the porosity and specific surface area of the filler, which is very conducive to the growth of complex bacterial flora, thereby achieving high purification efficiency.

The complex flora includes bacillus, nitrifying bacteria, decolorizing bacteria, yeast and lactic acid bacteria. Nitrifying bacteria are an important component for treating pollutants such as COD, but because of their slow propagation speed, they are often eliminated by harmful bacteria, resulting in the disappearance of the effective components of the flora. However, the utility model uses aerobic yeast with a very fast propagation speed to be responsible for grabbing the site. Nitrifying bacteria multiply; the other is anaerobic lactic acid bacteria, which reproduce very quickly, and are responsible for eliminating bacteria harmful to nitrifying bacteria in low-oxygen areas, thereby greatly improving the survival rate of complex flora and the removal rate of pollutants.

The water collection pipe and the water distribution pipe form a frame structure by connecting heat transfer pipes, and a hollow telescopic rod is embedded between two adjacent heat transfer pipes to ensure that the bacteria and microorganisms attached to the hollow telescopic rod and the outer periphery of the chain filler obtain a good temperature. The active environment is convenient for large-scale reproduction and the formation of pollutants.

The two partitions are provided with overflow holes, and the overflow holes of the partition separating the biochemical treatment area and the sedimentation drainage area are higher than the overflow holes of the partition separating the biochemical treatment area and the anaerobic fermentation area. To further ensure the anaerobic environment in the anaerobic fermentation area and the aerobic environment in the biochemical treatment area, of course, also enables the sedimentation drainage area to obtain a higher liquid level to improve the effect of sedimentation.

The cylinder at the top of the biochemical treatment area is provided with ventilation slant holes, and the slant air convection environment is formed by using the slant hole structure so that more complex flora can come into contact with fresh air.

The utility model realizes the technical purpose of feces, sewage, solid-liquid separation, and waste liquid direct discharge by dividing the septic tank into three areas: anaerobic fermentation area, biochemical treatment area, and sedimentation drainage area. The treatment temperature in the biochemical treatment area reaches the all-weather and all-regional characteristics of the system. As for the construction and installation, only the cylinder needs to be placed in the dug pit, which is very convenient.
