Embodiment

[0019] 1. Establish a constructed wetland with convenient access to water such as figure 1 As shown, the bed body, the water inlet baffle 2, the water outlet baffle 5, the first liquid guide plate 3 and the second liquid guide plate 4 are made of anti-seepage concrete, the water intake pipe is made of stainless steel pipe, and the plane of the bed body is rectangular. It is 300cm long and 100cm wide; the outer edge 1 of the water inlet bed is 100cm high.

[0020] The water inlet catchment area is composed of the first water distribution layer 6 and the water inlet baffle 2 . The first water distribution layer 6 is distributed at the bottom of the water inlet catchment area, and is composed of crushed stones with an average particle size of 2 cm, and the thickness of the accumulation is 20 cm; there is a 20 cm gap between the lower end of the water inlet baffle plate 2 and the bottom of the bed body, and the The upper end of the water baffle plate 2 is 25cm higher than the out...

Abstract

The invention discloses a method for treating sewage by utilizing a constructed wetland convenient for water sampling. The method comprises the steps: (1) the constructed wetland convenient for water sampling is established, the constructed wetland comprises a bed body, and the interior of the bed body is successively provided with a feedwater catchment area, a sewage treatment area and an outgoing water catchment area; the feedwater catchment area is composed of a first water distribution layer and a feedwater baffle plate; the sewage treatment area is composed of a second water distribution layer, a filler layer, water taking pipes and liquid guide plates; and the right side of an outgoing water baffle plate is provided with the outgoing water catchment area; and (2) the sewage flows into the feedwater catchment area, passes through the first water distribution layer, then goes into the sewage treatment area from a gap left at the lower end of the feedwater baffle plate; in the sewage treatment area, the sewage passes through the second water distribution layer, the filler layer and the water taking pipes, is treated by plant root systems and passes through the liquid guide plates, and finally the sewage flows out from the outgoing water baffle plate. Collected water samples which are convenient to take have representativeness, and a great convenience is provided for scientific studies on a constructed wetland technology.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a method for treating sewage by using an artificial wetland which is convenient for taking water samples. Background technique [0002] Constructed wetland sewage treatment technology has been widely used in the treatment of domestic sewage, agricultural drainage, industrial wastewater and other fields. The constructed wetland sewage treatment system has the advantages of strong impact load resistance, good nitrogen and phosphorus removal effect, and obvious improvement effect of ecological landscape. In my country, artificial wetland treatment technology has been paid attention to and adopted by more and more regions, which makes the prospect of this technology brighter. [0003] Constructed wetlands can be basically divided into three types according to the shape of water flow, namely surface flow constructed wetlands, subsurface flow constructed wetlands and compound flow con...
