Micro-aeration enhanced ecological floating bed sewage treatment device

Abstract

The invention discloses a micro-aeration enhanced ecological floating bed sewage treatment device which comprises water plants, a floating carrier, a combined packing layer, a fine bubble aeration pipeline, a support and an aeration machine, wherein plant holes are formed in the floating carrier, the water plants are planted onto the floating carrier through the planting holes and float on the water surface inside the micro-aeration enhanced ecological floating bed sewage treatment device, the combined packing layer is arranged below the floating carrier, the fine bubble aeration pipeline is circularly laid at the bottom of the micro-aeration enhanced ecological floating bed sewage treatment device through the support, and the aeration machine is connected with the fine bubble aeration pipeline at the bottom of the device. Aeration for the device is performed through a micro-aeration system, so that the growth of microbes on plant roots and the combined packing layer is promoted, the synergistic effect of a microbial system and a water plant system is promoted, the device can be used repeatedly, pollution to water cannot be caused, the cost is low, and the device is very suitable for being applied in a large area during natural water body pollution treatment.

Description

technical field [0001] The invention belongs to the field of sewage purification, in particular to a micro-aeration enhanced ecological floating bed sewage treatment device. Background technique [0002] Ecological floating bed is a new type of water ecological in-situ restoration technology. The ecological floating bed is a water surface soilless planting technology formed by utilizing the restoration function of aquatic plants and the principle of soilless cultivation, based on modern agriculture, and integrating ecological engineering measures. The ecological floating bed mainly relies on the absorption and assimilation of pollutants in the water body by the floating bed plants and the degradation of plant root microorganisms to purify the water body, so as to realize the green management of the natural water body. Ecological floating bed technology has high theoretical research value and good practical application prospect in natural water pollution control. [0003] T...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a micro-aeration enhanced ecological floating bed sewage treatment device, which aims to solve the problem that the traditional ecological floating bed technology is limited by the limited surface area of ​​plant roots for microorganisms to attach, and the oxygen content in natural water bodies is insufficient. Ecological floating bed system The number of microorganisms in the medium is insufficient, the species is relatively single, and the growth is slow, which leads to the problem of poor purification effect
