Sewage filtering equipment based on microbial reaction

Abstract

The invention relates to the field of sewage filtration, in particular to sewage filtration equipment based on microbial reaction, which comprises a treatment box, a first chamber and a second chamber, a sewage inlet pipeline and a sewage discharge pipeline are respectively arranged at the upper end and the lower end of the treatment box, and a first filter plate and a second filter plate are respectively arranged in the first chamber and the second chamber. The top of the first cavity and the top of the second cavity are each provided with a first water inlet and a second water inlet, the first filter plate and the second filter plate can alternately move to a pipe opening of a sewage inlet pipeline of the treatment box, and a switching device is further arranged in the second cavity and comprises a connecting mechanism and a switching mechanism; according to the device, the first filter plate and the second filter plate are connected through the connecting mechanism and the first filter plate is driven by the switching mechanism, so that sewage is filtered, switching of the first filter plate and the second filter plate under the condition that the sewage purification process is not influenced is also completed, and the sewage filtering efficiency is improved.

Description

technical field [0001] The invention relates to the field of sewage filtration, in particular to a sewage filtration equipment based on microbial reaction. Background technique [0002] The main pollution sources of domestic water bodies are domestic sewage and industrial wastewater. The treatment of industrial wastewater has not been fundamentally solved. Especially the high-concentration refractory organic industrial wastewater discharged from light industry, pesticide, coal chemical industry and other industries is very harmful to the environment. The existing microbial-based The working principle of the odor removal filter equipment is: make the sewage pass through a certain carrier such as gravel, slag, etc., and then form a film-like biological sludge on the filter plate. At the same time, a large number of microorganisms multiply on the biofilm, which can remove The odor and organic pollutants in the sewage are degraded. Finally, the aged biofilm falls off the filter ...

Problems solved by technology

[0004] According to the above-mentioned patent, the patent is provided with two generation chambers on the treatment box, so that when one generation chamber needs to be flushed after working for a period of time, the other generation chamber continues to work by rotating the adjustment core, and then, in sewage treatment During the process, the two generating chambers work sequentially through the conversion of the regulating core, and then achieve the effect of cleaning while working, and finally achieve the purpose of continuous cleaning. However, the regulating core is in the generating chamber, and after long-term work, its surface There will also be a large amount of biofilm attached, which will easily cause the nozzle of the sewage inlet pipe to be blocked and affect the filtration efficiency of sewage. Therefore, there is currently a need for a sewage filter that does not affect the sewage purification process and avoids blockage of the sewage inlet pipe when the replacement of the filter plate equipment
