Immobilized microorganism coupled-type grass planting ditch

Abstract

The invention discloses an immobilized microorganism coupled-type grass planting ditch. The immobilized microorganism coupled-type grass planting ditch comprises a plain soil foundation, a drainage layer, a planting soil layer, a surface permeable layer and an immobilized microorganism treatment unit, wherein the plain soil foundation is provided with a grass planting ditch body; the drainage layer is arranged at the bottom of the grass planting ditch body; the planting soil layer is arranged inside the grass planting ditch body and further located above the drainage layer; the surface permeable layer is arranged inside the grass planting ditch body and further located above the planting soil layer; the immobilized microorganism treatment unit comprises a plurality of water storage modules, the water storage modules are arranged at the bottom of the inside of the planting soil layer, and the multiple water storage modules are sequentially arrayed at intervals in the extension directionof the grass planting ditch body; and a plurality of immobilized microorganism modules are arranged in each water storage module, and the immobilized microorganism modules inside each water storage module are all arrayed at intervals. According to the immobilized microorganism coupled-type grass planting ditch, due to the water storage modules and the immobilized microorganism modules arranged onthe underground portion of the grass planting ditch body, pollutant loads are reduced while the rainfall runoff collected by the grass planting ditch body is regulated and stored, and the regulationand storage capacity and purification capacity to rainwater by the grass planting ditch body is strengthened.

Description

technical field [0001] The invention relates to the technical field of ecological water treatment facilities, in particular to the technical field of an immobilized microorganism coupling type grass planting ditch. Background technique [0002] As an ecological water treatment facility, Zhicaogou is widely used in the interception and transfer of surface rainwater runoff in the sponge city system. However, at present, various types of grass planting ditches have no significant function in terms of reduction of runoff pollutant load and corresponding water purification while performing the function of runoff transfer. This restricts the potential role of grass-planting ditch in regional runoff control and water environment governance. Immobilized microorganism technology uses the metabolic function of microorganisms to absorb, assimilate and transform pollutants in surrounding water bodies by setting immobilized carriers containing engineered microorganisms in substrates or ...
