specific Embodiment

[0031] refer to Figure 1 to Figure 2 As shown, the constructed wetland sewage treatment system of this embodiment includes a water distribution channel 4 for supplying sewage and a collection channel 5 for collecting water purified by the sewage treatment system. The functional packing area 2 and the second functional packing area 7 for the purified water of the first functional packing area 2 to pass through horizontally. Refers to the horizontal flow of sewage from one end of the second functional packing area 7 to the other end. In specific applications, the first functional packing area 2 is connected to the water distribution channel 4 through a plurality of water distribution pipes 401 arranged at the bottom of the first functional packing area 2 , Sewage is input to the bottom of the first functional packing area 2, and a plurality of water collecting pipes 402 are arranged on the upper part of the first functional packing area 2 for collecting the sewage passing throu...

Abstract

An improved constructed wetland sewage treatment system comprises a water distribution channel and a water collection channel, a first functional filler area which is connected with the water distribution channel and used for allowing sewage to longitudinally penetrate through so as to purify the sewage, and a second functional filler area which is communicated with the first functional filler area and used for allowing purified water of the first functional filler area to horizontally penetrate through, the water collecting channel is connected with the second functional filler area so as to collect purified effluent of the second functional filler area. According to the invention, sewage firstly flows through the filler in the longitudinal direction to form a vertical flow with better nitration capacity, and then the sewage horizontally flows through the filler to form a horizontal underflow, so that the combined type can improve the removal effect on indexes of pollutants such as total nitrogen, ammonia nitrogen, five-day biochemical oxygen demand, chemical oxygen demand, suspended solids, heavy metals and the like in the sewage; and the effluent quality of the wetland is optimized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an improved constructed wetland sewage treatment system. Background technique [0002] Constructed wetlands are a technology for treating sewage and sludge by utilizing the triple synergy of physics, chemistry and biology of soil, artificial media, plants and microorganisms. Its mechanism of action includes adsorption, retention, filtration, redox, precipitation, microbial decomposition, transformation, plant shading, residue accumulation, transpiration of water and nutrient absorption, and the action of various animals, thereby achieving the purpose of purifying water quality. It can not only green the land and improve the regional climate, but also increase the oxygen content in the air and promote a virtuous cycle of the ecological environment. Therefore, constructed wetlands are often used in the treatment of tail water from municipal sewage plants, or in the practi...
