Description

Device for promoting effective recovery of submerged plants in polluted water body

Technical Field

The utility model relates to an environmental protection technical field, concretely relates to promote effective recovery unit of contaminated water submerged plant.

Background

The improvement of the water body is promoted, the recovery and reconstruction of an ecosystem can effectively transfer the water body pollution, inhibit the water quality from rebounding, even in a water area with less serious exogenous pollution, realize the balance of the inlet and outlet of nutritive salt of the water body, and gradually realize the self-restoration of the water body and the virtuous cycle of the water body ecology.

From the service function that the water can provide, healthy water ecosystem mainly refers to the grass type clear water steady state water body that takes submerged plants as ecological cornerstones. Submerged plants are the most important primary producers in aquatic ecosystems. The submerged plants synthesize water and carbon dioxide into carbohydrates through photosynthesis, further synthesize fat and protein, and are the most important sources of energy input of a water body ecological system; the submerged plants absorb and fix nutrient elements such as nitrogen and phosphorus and adsorb a large amount of biological and non-biological suspended substances in the water body so as to improve the transparency of the water body, increase the dissolved oxygen of the water body and continue the food chain of the water body, so that the submerged plants are the most important carriers for purifying the water quality and constructing a healthy ecological system of the water body; allelochemicals secreted by submerged plants can destroy the physiological metabolism function of algae, and are natural 'gram' of algae; the submerged plants occupy an important ecological niche at the interface of water and sediments, provide food sources and inhabitation sites for plankton and aquatic animals, and are the cornerstone of the water body ecosystem. The position of the submerged plant in the ecological purification and restoration of the water body can not be replaced.

The light factor is a key for judging whether the submerged plant grows well or not and even whether the submerged plant can survive, and meeting the light factor requirement of the submerged plant is important for promoting the growth of the submerged plant and improving the water quality purification capacity of the submerged plant. When organic matters produced by photosynthesis of submerged plants are not enough to compensate consumption of respiration of the submerged plants, the plants die, algae become dominant species, the ecological system jumps to an algae type turbid water stable state, and if the ecological system continuously deteriorates, the ecological system jumps to a bacterial type turbid water stable state water body (black and odorous water body).

The method for changing the bottom sediment elution position of the polluted water body utilizes a physical mechanical method to elute the deposited pollutants of the bottom sediment, then separates the pollutants from the elution water, and converts the separation of the deposited pollutants into sewage separation; the cleaned sediment covers the substrate in situ to prevent the release of deep pollutants, thereby achieving the double effects of separating the deposited pollutants and covering the substrate sludge. Can remove the sediment pollutants in a short time, improve the transparency of the water body, create a good growing environment for aquatic organisms, particularly submerged plants, promote the conversion of the algae-type water body to the grass-type water body, and be beneficial to realizing the virtuous cycle of self-purification and self-balance of the water body.

The method for changing the polluted water bottom mud elution in situ still has some defects: for the water body with the water depth of 1.5-2.5 meters, the transparency of the water body is low after purification, the light is lost after being irradiated into the water body, the submerged plants cannot obtain enough light for photosynthesis or the photosynthesis rate is lower than the respiration rate, and then the submerged plants die, and the water ecosystem cannot be effectively recovered.
