A ceramsite soil-based artificial wetland device conducive to microbial reproduction

Abstract

The invention provides a ceramsite soil-based artificial wetland device that is beneficial to the reproduction of microorganisms, including an artificial wetland pool in the shape of a large upper and a lower small prism. , and the large-grain layer, the medium-grain layer and the small-grain layer are respectively filled with ceramsite with corresponding particle sizes. The large-grain layer is laid with a water distribution pipe, and the water inlet of the water distribution pipe is connected to a water distribution device. Wetland plants are planted on the small-grain layer, and the small-grain layer The opening of the layer is lower than the opening height of the constructed wetland pool, and there is an overflow tank between the small grain layer and the constructed wetland pool, and a drainage device for discharging the treated water is provided in the overflow tank, and there is a drain on the side of the constructed wetland pool for receiving Sewage intake tank. In a word, the present invention has the advantages of novel structure, perfect system, good treatment effect and the like.

Description

technical field [0001] The invention belongs to the technical field of constructed wetlands, and in particular relates to a ceramsite soil-based constructed wetland device which is beneficial to the reproduction of microorganisms. Background technique [0002] Constructed wetland is a ground similar to swampland that is artificially constructed and operated under control. Sewage and sludge are distributed to the artificially constructed wetland in a controlled manner. When sewage and sludge flow in a certain direction, they are mainly used It is a technology for treating sewage and sludge through the triple synergy of physics, chemistry and biology of soil, artificial medium, plants and microorganisms. Its mechanism of action includes adsorption, retention, filtration, redox, precipitation, microbial decomposition, transformation, plant shading, residue accumulation, transpiration of water and nutrient absorption, and the action of various animals. [0003] With the rapid d...

Problems solved by technology

[0004] However, the existing artificial wetland mode usually flows the sewage vertically from the surface to the bottom. This mode often emits the peculiar smell in the sewage to the surrounding wetland, causing environmental deterioration, and the permeable treatment method, the plants above the wetland The adsorption process of sewage is short, and the dirt in the sewage is deposited on the surface of the wetland, which isolates the wetland from the outside air, resulting in slow growth of microorganisms in the wetland and a decrease in the efficiency of sewage treatment.
