Embodiment 1

[0029] like figure 1 As shown, a constructed wetland purification treatment system suitable for black and odorous rivers in cities and towns includes a fixed frame above water, a filtration and adsorption system, an ecological floating bed 30 and several water distribution pipes 50; Grid 12; the fixing member is arranged on one side of the bearing platform, and several grids 12 are arranged on the other side of the bearing platform, and the fixing member, the bearing platform and the grid 12 surround and form a bearing The receiving tank is divided into left and right parts, the side close to the fixing part is marked as the water inlet tank, and the side close to the grille 12 is marked as the water outlet tank; the filtration and adsorption system includes a first purification system and a second purification system. system; the first purification system includes an ammonia nitrogen adsorption filler layer 21 and an iron-carbon micro-electrolysis filler layer 22 stacked up a...

Embodiment 2

[0039] like figure 2 As shown, the difference between embodiment 2 and embodiment 1 is that the bearing platform is a concrete bearing surface, and the river surge pipeline 14 is arranged on the pretreatment water body, and the periphery of the river surge pipeline 14 is covered with concrete, thereby forming the The concrete bearing surface; one side of the river pipeline 14 is adjacent to the bank 15, and the bank 15 forms the fixing member; the other side of the river pipeline 14 is provided with a grid 12; the bank 15, the concrete bearing surface And grid 12 surrounds and forms described accommodating groove. Utilize the direct construction on the river pipeline 14 on the water body, and the construction cost is low.

[0040] The artificial wetland purification treatment system suitable for black and odorous rivers in cities and towns provided by the present invention, its purification steps are as follows:

[0041] (1) The polluted water body of the river course is fi...

[0049] Location: Shengtang Chung, Dali Town, Nanhai District, Foshan City, Guangdong Province

[0050] In this project, the construction of the filtration and adsorption system is carried out on the basis of the original river pipe. The whole structure is 620 meters long, 1.25 meters wide and 0.8 meters thick. The operation process is as follows:

[0051] (1) Before construction, first extract the indigenous nitrifying bacteria and spores from the river, and plant them in the infrared porous filler to form a microbial porous filler;

[0052] (2) Install the peripheral grid, water distribution pipe and water pump circuit first on site;

[0053] (3) Install the microbial filler package and the iron-carbon micro-electrolysis material package, install a backwash pipe between the iron-carbon micro-electrolysis material packages, spread the ammonia-nitrogen adsorption filler on the iron-carbon micro-electrolysis material layer, and then place it in the working area of ​​the ammonia...

Abstract

The invention discloses an artificial wetland purifying treatment system applicable to urban black and odorous river courses. The system comprises an overwater fixed frame, a filter adsorption system, an ecological floating bed and a water distributor, wherein the overwater fixed frame comprises a bearing platform, a fixture and a grid; one side of the bearing platform is provided with the fixture, and the other side is provided with the grid; the fixture, bearing platform and grid form a containing tank; the left and right sides of the containing tank are respectively marked as a water inlet tank and a water inlet tank; the filter adsorption system comprises a first purification system and a second purification system; the first purification system comprises an ammonia nitrogen adsorption filler layer and an iron-carbon microelectrolysis filler layer which are laminated up and down in the water inlet tank; the second purification system comprises a microbial filler layer arranged in the water outlet tank; the ecological floating bed is arranged on a pretreated water body and is adjacent to the grid; a fiber filler is bound with the bottom of the ecological floating bed; the water inlet end of the water distributor is provided with in the pretreated water body; and the water outlet end of the water distributor is arranged above the ammonia nitrogen adsorption filler layer. The system can implement efficient decolorization, denitrification and dephosphorization, has the advantages of small occupied area and low cost, and is easy for maintenance.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an artificial wetland purification treatment system suitable for black and odorous river courses in cities and towns. Background technique [0002] According to the 2015 National Urban Black and Odor Water Information released by the Ministry of Environmental Protection and the Ministry of Housing and Urban-Rural Development, 73.9% of cities above the prefecture level in the country were polluted, and a total of 1,861 black and odorous rivers, lakes, and ponds were detected, of which black and odorous rivers accounted for 85.7%. The improvement of rivers, reservoirs, lakes and other water areas in China is still basically in the stage of water quality improvement and landscape construction, and the water conservancy network in urban areas is not perfect, resulting in the serious problem of river basin pollution. In 2015, China officially released the "Water Pollution Pre...
