Movable type plant floating island chain applicable to estuary of lake

Abstract

The invention relates to a movable type plant floating island chain applicable to an estuary of the lake. A series of floating island monomers are connected by an antiseptic rope to form a floating island chain, wherein the head end of the floating island chain is fixed to a shore, and the tail end of the floating island chain is controlled by retracting and releasing a rope system, so that the floating island chain is arranged along the full section of a riverway during the non-flood discharge period, and is moved to the shore to be fixed during the flood discharge period or high wind. The movable type plant floating island chain has the advantage that: the capacity of purifying the floating islands is improved by planting aquatic plants with a function of purifying water quality on a carrier and collocating with biological filter bulb fillers hung in a hexahedral frame on the lower part of a floating bed through the aquatic plant purification technology and biomembrane technology. Aseries of floating island monomers are connected together to form the movable type plant floating island chain of which the head end is fixed and the tail end is movable, so the movable type plant floating island chain can be arranged along the full section to purify the water quality fully and also can be moved to the shore during the flood period without influencing flood discharge; and the relation of the improvement of the water quality and the drainage of the flood discharge is coordinated, navigation channels are reserved in the riverway to meet the demands for shipping, so the movable type plant floating island chain is suitable for the purification of the water quality at the estuary of the lake and ecological restoration.

Description

technical field [0001] The invention relates to a mobile plant floating island chain suitable for the estuary of a lake. The mobile floating island chain is used to purify the water body in situ at the estuary of the lake without affecting the normal flood discharge and shipping functions of the river. Enhanced water purification and ecological restoration engineering technology field. Background technique [0002] The pollutants carried by the rivers entering the lake are the main pollution sources of the lake, and the pollutants flow into the lake through the rivers entering the lake in large quantities, which is one of the main factors leading to the decline of the water quality of the lake. As the last barrier to improve the water quality of the lake, the ecological restoration and water purification of the estuary of the lake have become an important part of solving the problems of lake water pollution and eutrophication. [0003] At present, the commonly used estuary ...

AI Technical Summary

Problems solved by technology

However, the rivers entering the lake are generally used as flood passages and have the function of flood discharge. At the same time, there may be shipping requirements. The above-mentioned technologies have not effectively coordinated the relationship between the water quality improvement of the estuary entering the lake, flood discharge, and shipping. Therefore, in specific applications there are certain restrictions
