Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] Such as figure 1 The drop type thin water layer artificial wetland reoxygenation tank shown includes a reoxygenation tank bed body 1, and the slope of the reoxygenation tank bed body 1 along the length direction is 0.7%. A plurality of deflectors 2 with the same width as the oxygen tank bed body 1. To facilitate construction, the reoxygenation tank bed body 1 adopts plain concrete.

[0024] Such as figure 2 As shown, the flow deflector 2 is sequentially composed of a front lap 21 , a first flow guide section 22 , a second flow guide section 23 , a third flow guide section and a rear lap edge 27 from the front end to the rear end. The first guide section 22 is a downward smooth curved surface, the second guide section 23 is an upward smooth curved surface, and the third guide section is sequentially composed of the first folded surface 24, the second folded surfac...

Abstract

Disclosed is a drop-jump type thin-water layer constructed wetland reaeration groove, comprising a complex oxygen groove bed body, wherein the complex oxygen groove bed body is provided with a slope in the length direction thereof; the complex oxygen groove bed body is provided with a plurality of flow deflectors from a water inlet to a water outlet, with the flow deflectors being connected in anend to end manner; the front segment of the flow deflector is a downward curved surface, with the rear segment thereof being an upward curved surface; and the front segment of the flow deflector s higher than the rear segment of the flow deflector. The drop-jump type thin-water layer constructed wetland reaeration groove features simple structure, high efficiency, and convenient making and installation, requires no additional external energy, with little loss of the water head, and effectively solves the problem that the main body of the constructed wetland is lack of oxygen.

Description

technical field [0001] The invention relates to environmental protection technology and waste water treatment technology, in particular to a drop-jump type thin water layer artificial wetland reoxygenation tank. Background technique [0002] The research on sewage purification in artificial wetlands began in the late 1970s as a new wastewater treatment technology, which is characterized by low investment, low cost, good treatment effect, simple maintenance and convenient operation, and is more suitable for small water volume and small fluctuations in water quality. , Sewage treatment in villages and towns with low management level. [0003] Insufficient dissolved oxygen is an important factor restricting the treatment efficiency of constructed wetlands. The dissolved oxygen in traditional constructed wetlands mainly comes from the natural reoxygenation of the atmosphere, the oxygen secreted by plant roots and the oxygen carried by sewage. Most of the microorganisms in sewag...
