Embodiment Construction

[0014] like figure 1 and figure 2 As shown, the sewage resource anaerobic treatment device includes a closed pool body 1 provided with a sewage inlet 11 and a sewage outlet 12. The upper part of the inner space of the pool body is hollow, and the hollow upper part is used to collect biogas, and thus keep the inside of the pool Good anaerobic space, the top of the pool body is provided with a biogas outlet 13 . The lower part of the inner space of the pool body is fixed with a baffle plate 2, and the baffle plate 2 divides the lower space of the pool body into a meandering sewage flow channel 3. This structure can make the sewage flow longer. channel, and make the closed pool body 1 occupy a smaller area; biological filler 4 is suspended in the sewage flow channel 3, and the biological filler 4 is composed of microbial treatment sheets, which has high tensile strength, high porosity and surface area, and the microbial hanging The membrane is fast and has a large biomass. It ...

Abstract

The invention discloses a sewage recycling anaerobic processing device, which comprises a closed pool body provided with a sewage inlet and a sewage outlet, wherein the upper part of the internal space of the pool body is hollow; the lower part of the internal space of the pool body is fixedly provided with a baffle plate 2; the baffle plate 2 divides the lower space of the pool body into a sewagechannel which is circuitously bent; the sewage channel is hung with biological fillers inside; the bottom of the sewage channel is provided with a sludge backsurging device; and the top of the pool body is provided with a methane outlet. The baffle plate 2 increases the sewage flowing time so as to increase the anaerobic reaction time; a great mount of anaerobic bacteria are attached on the biological fillers hung in the channel to ensure that sewage fully contacts the anaerobic bacteria and greatly improve the anaerobic efficiency; and the sludge backsurging device has the function of backsurging sludge on the bottom to ensure that adequate anaerobic bacteria are attached on the biological fillers and make the anaerobic bacteria in the sludge fully participate the anaerobic reaction at the same time so as to further improve the dirt removal rate.

Description

technical field [0001] The invention relates to a device for treating sewage, in particular to a device for treating sewage by adopting an anaerobic method. Background technique [0002] With the rapid growth of my country's economy, water resources are becoming more and more scarce, and the impact of sewage on the environment is increasing. The contradiction between economic development and resources and environment is becoming increasingly acute, and sewage treatment has become a major problem. [0003] Anaerobic sewage treatment is an important step in the sewage treatment process, but the disadvantages of existing anaerobic treatment devices are: short process, complex structure, difficult survival of anaerobic bacteria, and low COD removal rate. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a sewage resource anaerobic treatment device with high COD removal rate, high anaerobic bacteria survival rate, efflu...
