Abstract

The invention discloses a combined ecological floating bed for water quality improvement of a heavily contaminated water body. The combined ecological floating bed is composed of a floating bed body and a hanging body hung below the floating bed body, wherein the floating bed body is composed of a rectangular floating bed frame and a supporting screen, the rectangular floating bed frame is composed of PVC pipes and connecting members and separated into thee rectangular units, the supporting screen is fixed on each rectangular unit and may be a nylon mesh, a plastic mesh or a fibrous mesh, gramineous plants or floating plants are planted on the supporting screen, the hanging body is a rectangular box with upper opening, the rectangular box is filled with a plantation matrix, submerged plants are planted on the plantation matrix, and the plantation matrix is prepared from clay, Chinese medicine residue and vermiculite according to a certain weight ratio. Through reasonable collocation and plantation of water plants, the heavily contaminated water body is maximally purified, the population of submerged plants is effectively recovered, and transparency of the water body is improved.

Description

technical field [0001] The invention relates to a water quality purification device, in particular to a combined ecological floating bed used for water quality purification of heavily polluted water bodies. Background technique [0002] In my country, the number of eutrophic lakes and hypertrophic lakes accounted for 66% and 22% of the total number of lakes. Such as Taihu Lake in Jiangsu, Dianchi Lake in Kunming, etc. The eutrophication of rivers and lakes is related to human activities in the process of accelerated urbanization, rapid population expansion, and rapid development of industry and agriculture. The restoration and effective control of eutrophic water bodies have become the only way for the sustainable development of economy, society and environment. [0003] The restoration techniques and methods for eutrophic water bodies, including in-situ and ex-situ restoration techniques, have developed rapidly. These include sludge dredging technology, water diversion d...
