Description

Sewage shallow source ecological floating bed restoration device

technical field

The utility model relates to a sewage treatment system, in particular to a sewage shallow source ecological floating bed restoration 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 solid-liquid separation and direct discharge of waste liquid, and the entire purification process is time-consuming and cumbersome. How to improve the purification efficiency and speed of sewage 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, which includes 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 regarding the direct discharge of waste liquid and the speed of purification.

Contents of the invention

The utility model provides a sewage shallow source ecological floating bed restoration device with simple construction, solid-liquid separation, direct discharge of waste liquid, and rapid purification.

An ecological floating bed repair device for shallow sewage sources, including a cylinder formed by 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 two areas by a partition, The two areas mentioned are the ecological floating bed restoration area and the biochemical treatment area in sequence.

The ecological floating bed restoration area includes a submerged elbow connected to a sewage pipe and a floating bed planted with plants, and the top of the plants protrudes from the cylinder. The submerged elbow structure 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 An anaerobic fermentation zone is formed in the cylindrical area connected to the sewage pipe through the submerged water bend structure, and an anaerobic fermentation is formed through a closed anaerobic environment, which can decompose protein organic matter and kill parasite eggs and germs. And by installing the cylinder shallow source underground, the plants can survive through the cylinder. The shape of the floating bed is square, triangular, circular and other structures. The roots of aquatic plants form a dense net in the sewage, which absorbs a large amount of suspended solids in the water body, and gradually forms a biofilm on the surface of the plant root system. The microorganisms in the film engulf and metabolize the water. Pollutants are inorganic substances, making them nutrients for plants, promoting plant growth and greatly improving the speed of sewage treatment. Of course, in this process, a large number of pollutants will also precipitate and purify the sewage.

The cylinder at the top of the ecological floating bed restoration area has growth holes for accommodating plant growth, and embedded light-transmitting panels to promote plant photosynthesis and increase plant vitality and growth speed.

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. In the biochemical treatment area, the sewage treated in the ecological floating bed restoration area has been treated in a deep and harmless manner, and it has reached the discharge standard of the water body and can be discharged directly.

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 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 divides the cylinder into two areas, the ecological floating bed repair area and the biochemical treatment area, adopts the high-efficiency treatment of the ecological floating bed to speed up the purification speed, and realizes the solid-liquid separation of sewage by the evolution of harmless treatment from the biochemical treatment area. The technical purpose of direct discharge of waste liquid.
