Embodiment Construction

[0009] see figure 1 , the present invention provides a combined constructed wetland sewage treatment system, comprising a grid 1, an aeration water collection tank 2, a sedimentation tank 3 and a constructed wetland 4 connected in sequence, the bottom of the aeration water collection tank is provided with a Aeration device 2.1, the bottom of the sedimentation tank is connected to a sludge pump, and the discharge pipe of the sludge pump is connected to a sludge thickening tank 6. The constructed wetland adopts a horizontal baffle structure, and a water storage tank 5 is provided at its outlet.

[0010] The grill can adopt a mechanical grill to improve efficiency and the screening effect on sundries.

[0011] The aeration device may be an aeration head connected to a high-pressure air supply pipeline. The aeration can be carried out in the way of intermittent work, that is, after a certain amount of aeration, the aeration is stopped for a period of time, and the aeration is car...

Abstract

The invention relates to a combined type artificial wetland sewage treatment system, which comprises a bar screen, an aeration water-collecting tank, a sedimentation tank and an artificial wetland connected in turn, wherein the bottom of the aeration water-collecting tank is provided with an aerator for aeration in the tank; the bottom of the sedimentation tank can be connected with a sludge pump; a discharge pipeline of the sludge pump is connected with a sludge concentration tank; and the artificial wetland adopts a horizontal baffling structure, and the water outlet is provided with a water storage tank. Because the aerator is arranged in the water-collecting tank to form the aeration water-collecting tank, the aeration and aerobic biochemical treatments are performed while collecting water, which reduces the pollutant content in the sewage, is helpful to the subsequent sludge sedimentation in the sedimentation tank to separate out the sludge in the sewage effectively, and simultaneously saves the space and equipment, and avoids fermentation and peculiar smell in the process of collecting water; and because the artificial wetland adopts the horizontal baffling structure, the processing effect is improved. The combined type artificial wetland sewage treatment system can treat the sewage with higher concentration and has lower pretreatment cost.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a synthetic wetland-based comprehensive sewage treatment system combined with various treatment methods, which belongs to the field of environmental protection. Background technique [0002] Since 1804, the British first used sedimentation and filtration technology as a centralized water treatment plant. In 1884, the Americans invented the coagulation, sedimentation, filtration, and chlorine disinfection technology, which has been used for 120 years. There are new discoveries and improvements in treatment, but the treatment process of domestic water basically remains the same, essentially no update and breakthrough. However, the water source to be treated has undergone great changes: the water source a hundred years ago was not polluted due to the underdevelopment of industry and agriculture. Over the past few decades, the development of modern industry, especially the sudden and rap...
