Problems solved by technology

[0003] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an integrated filling and laying method for the constructed wetland matrix. When replacing the clogged matrix in the traditional constructed wetland, the engineering quantity is large, the replacement is difficult, and the constructed wetland needs to be shut down during the replacement. The defect has been significantly improved

Embodiment Construction

[0023] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0024] An integrated filling and laying method of constructed wetland matrix. The constructed wetland is composed of several relatively independent and movable modules in series, parallel or series-parallel combination, which can be quickly combined horizontally or vertically at the construction site according to the processing needs. connection to solve the shortcoming of the long construction cycle of constructed wetlands.

[0025] Such as figure 1 As shown, module one 1 is located at the water inlet, wherein each module includes a cubic frame 12, and matrix unit one 3, matrix unit two 4 and matrix unit three with pull ring one 11 on the top are sequentially arranged in the frame 12 along the water flow direction 5. Among them, matrix unit 1 3, matrix unit 2 4 and matrix unit 3 5 are packing block 1 6, packing block 2 7, packing block 3 8 and...

Abstract

The invention relates to an artificial wetland substrate integral filling and laying method. The artificial wetland is composed of a plurality of modules with a manner of series connection, parallel connection or a combination of series and parallel connections. A module 1 is positioned at a water inlet end. Each module comprises a cubic frame. A substrate unit 1, a substrate unit 2 and a substrate unit 3 are sequentially arranged along a water flow direction in the frame. The substrate unit 1 and the substrate unit 3 have a same structure which is a wedge-shaped structure with the upper part smaller than the lower part. The substrate unit 2 has a wedge-shaped structure with the upper part larger than the lower part, and is blocked between the substrate units 1 and 3. Two sets of pulleys are arranged on the lower surface inside each module on the side parallel to the water flow direction. The substrate unit 1 and the substrate unit 3 are respectively arranged on a set of pulleys. When the substrate unit 1 and the substrate unit 3 are respectively under leftward and rightward pressings, the substrate units can move left and right. The invention provides the artificial wetland substrate integral filling and laying method.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated filling and laying method of a constructed wetland matrix, which is especially suitable for short-term, emergency sewage treatment and sewage treatment in small and medium-sized rural towns with low population density. Background technique [0002] Constructed wetland is a sewage biological treatment technology developed in the late 1970s. Due to the advantages of low investment and operation costs and convenient maintenance and management, this technology is especially suitable for rural areas with relatively backward capital and technology. Under the background of centralized management of rural environment in my country, this technology has been widely promoted and used. However, in the process of field operation, people found that although this technology has the advantages of convenient maintenance and management, it also has the obvious d...
