Oxygenation type water distribution device

Abstract

The invention discloses an oxygenation type water distribution device which comprises a water distribution pipe sleeve, wherein the top of the water distribution pipe sleeve is fixedly communicated with the bottom of a flow guide pipe through formed water distribution micropores, the top of the flow guide pipe is fixedly communicated with the bottom of a flow guide plate, and the top of the flow guide plate is fixedly connected with the bottom of a flow baffle through a formed flow guide groove. The oxygenation type water distribution device is simple in structure, convenient to install, capable of rapidly achieving newly-built installation and optimization and transformation of an existing water distribution system, even in water distribution, easy to maintain and easy to disassemble, the problems that the water distribution device is difficult to disassemble and assemble due to hole blockage, and water needs to be cut off for overhaul can be effectively solved, efficient oxygenation can be achieved while water is evenly distributed, the dissolved oxygen content of sewage can be increased in the process, the odor of the sewage is eliminated, the sewage treatment effect is improved, and the oxygen content per unit volume is increased.

Description

technical field [0001] The invention relates to the technical field of rural sewage treatment systems, in particular to an oxygen-increasing water distribution device. Background technique [0002] There are many kinds of technological methods for rural sewage treatment. Due to the characteristics of "free operation", "low maintenance" and "low energy consumption", biological filters are still widely used in developed countries and can effectively save the use of water resources. . The biological filter process distributes water to the filter tank through water pumps or gravity, and the sewage passes through the main pipe to the branch pipe, and then flows out from the water distribution holes in the branch pipe and enters the filter material layer. [0003] Under normal circumstances, due to the large area of ​​the biological filter, uneven water distribution is prone to occur, which makes the treatment effect poor and the pollutant removal rate is not high. The water dist...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an oxygen-increasing water distribution device to solve the problem that the existing biological filter proposed in the above background technology is prone to uneven water distribution due to its large area, which makes the treatment effect poor and pollutants The removal rate is not high. The water distribution method of the conventional biofilter is to perforate the water distribution pipe. The orifice is large and the flow rate is low. It is easy to attach biofilm inside the water distribution pipe or around the water distribution hole. Over time, the pipeline or The water distribution hole is blocked, and the pipeline needs to be disassembled or the water should be stopped for cleaning, which is difficult to maintain and affects the normal operation of the sewage treatment process
