Abstract

The invention relates to the technical field of sewage treatment, in particular to a system and a method for treating sewage by using an unpowered oxygen-supply ecological filter. The system comprises an upper layer of vertical flow filter and a lower layer of horizontal baffling filter, wherein an unpowered oxygen-supply system is arranged in the upper layer of vertical flow filter and comprises a horizontal vent pipe, a vertical vent pipe and a porous water collecting branched pipe; the horizontal vent pipe is horizontally arranged on the lower part of the upper layer of vertical flow filter; one end of the horizontal vent pipe is communicated with the porous water collecting branched pipe and the other end of the horizontal vent pipe extends out of the upper layer of vertical flow filter; the vertical vent pipe is vertically arranged in the upper layer of vertical flow filter; the bottom end of the vertical vent pipe is communicated with the porous water collecting branched pipe; and the top end of the vertical vent pipe is higher than the top of the upper layer of vertical flow filter. The system and the method have the beneficial effects of high pollution control efficiency, obvious total nitrogen removing effect, small occupied area and good environmental benefit. Unpowered oxygen supply is realized, so the system and the method are low in operating cost and wide in application.

Description

[technical field] [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system and method for an unpowered aerobic ecological filter. [Background technique] [0002] The discharge of rural domestic sewage into the environment without effective treatment can cause serious pollution of rural surface water runoff, and can also pollute the water quality of drinking water sources, increase water supply risks and treatment costs for rural residents, and cause difficulties in rural domestic water use. But at the same time, due to the influence of natural conditions and living habits, rural domestic sewage has the characteristics of scattered discharge and difficult collection. Therefore, it is particularly important to develop efficient and low-consumption rural domestic sewage treatment technology according to local conditions. [0003] Constructed wetland technology has the characteristics of low energy consumption in operati...
