Problems solved by technology

For the treatment of low-COD domestic sewage, such as rural domestic sewage, if the treatment process of conventional sewage plants is followed, the treatment cost and operating cost are obviously higher, which will easily lead to the situation that rural domestic sewage treatment facilities are "affordable to build but unaffordable to use"

Embodiment

[0027] The low-energy domestic sewage treatment system provided by this application includes an upper plate tower aerobic bioreactor and a lower sedimentation tank;

[0028] The plate tower aerobic bioreactor includes a tank 1 for treating sewage and a solubilizing device inside the tank 1;

[0029] The tank body 1 has an open top and is generally designed as a cylindrical structure; the sewage inlet pipe 3 can directly extend into the middle of the tank body through this water inlet so that the sewage directly contacts the solubilizing device in the middle (of course, the sewage enters The water pipe 3 also reasonably determines the extension length inside the tank according to the water pressure, pipe diameter, flow rate, etc.);

[0030] The middle part of the bottom plate of the tank body 1 is designed with an overflow hole 10. The total area of ​​the overflow hole 10 should be larger than the overflow area of ​​the water inlet so that the sewage can enter the lower sedimen...

Abstract

The invention belongs to the technical field of sewage treatment equipment, and particularly relates to a low-energy-consumption domestic sewage treatment system, which comprises a plate tower type aerobic bioreactor at the upper portion and a sedimentation pool at the lower portion, wherein the plate tower type aerobic bioreactor comprises a tank body for treating sewage and a solubilizing devicearranged in the tank body, and the sedimentation pool comprises a sedimentation pool body, a mud bucket arranged in the sedimentation pool, and a flow guide cylinder communicated with the reactor. According to the invention, specific low-concentration domestic sewage (such as rural domestic sewage) is subjected to biochemical treatment by adopting the domestic sewage treatment system provided bythe invention, the operation cost is low, excessive power equipment is not needed, the maintenance is simple, the sewage treatment operation cost can be well reduced, and the biochemical treatment effect and the continuous operation of sewage treatment can be well ensured, so that the domestic sewage treatment system has good practical value and popularization and application significance.

Description

technical field [0001] This application belongs to the technical field of sewage treatment equipment, and specifically relates to a patent application for a low-energy domestic sewage treatment system. Background technique [0002] In the process of sewage treatment, one of the main evaluation indicators for the design of sewage treatment process and treatment effect is the COD value of water body. For the treatment of low-COD domestic sewage, such as rural domestic sewage, if it is treated according to the conventional sewage plant treatment process, the treatment cost and operating cost are obviously higher, and it is very easy to cause rural domestic sewage treatment facilities to be "affordable to build, but unaffordable to use". In response to this situation, it is extremely necessary to develop and design a sewage treatment system with low operating costs and low treatment costs in light of the differences in actual sewage treatment objects, so as to adapt to the treat...
