Ecological restoration monitoring system for early warning outbreak of water blue algae

Abstract

The invention relates to the field of restoration of water ecological environments. An ecological restoration monitoring system for early warning outbreak of water blue algae is an ecological restoration monitoring system for preventing the outbreak of blue algae and aims at monitoring the generation and development of blue algae and early-warning of algal bloom so as to provide decision-making basis for water ecological restoration. According to the technical scheme, the ecological restoration monitoring system is characterized in that a chlorophyll sensor is used for acquiring components of blue algae in water; a sunshine duration sensor and a wind speed and direction sensor are used for acquiring hydrological environment for the growth of blue algae; a water fish detector is used for acquiring the quantity of fish in water of different depth; a shooting sensor is used for acquiring the water condition of a water area to be monitored; the data acquired by the sensors are transmitted to a monitoring system platform through a data acquiring managing module, and the monitoring system platform manages the ecological information of water suffering from algal bloom early-warning in different water areas according to the data.

Description

technical field [0001] The invention belongs to the field of online water body ecological restoration monitoring, and in particular relates to monitoring of water body pollution caused by cyanobacteria in the water body and ecological restoration. Background technique [0002] At present, cyanobacteria blooms occur frequently in inland lakes such as Taihu Lake and Chaohu Lake. At a suitable temperature, blue-green algae grow wildly in eutrophic water bodies, causing oxygen depletion in water bodies, death of aquatic organisms in water bodies, and death of aquatic organisms. The further release of nutrients intensified the eutrophication. The cyanobacteria populations floated up and gathered on the water surface to form algae blooms, while the populations of algae in the water below decreased significantly. Before and after the formation of algae blooms, the total amount of chlorophyll in the same water column There may not be much change, and in most cases this sudden "bloom...

AI Technical Summary

Problems solved by technology

[0003] At present, a series of water quality parameters such as chlorophyll a, dissolved oxygen in water, turbidity, total phosphorus, total nitrogen, and pH value are used in domestic lake areas to infer the comprehensive nutritional index of water bodies, and appropriate models are used to infer the nutritional status of water bodies. However, multiple water quality parameters On the one hand, the equipment cost and maintenance cost are high, and it is difficult to popularize in districts and counties; on the other hand, the monitoring parameters of hydrology and water quality reflect the specific conditions of each level of the water body. Degree, transparency, pH) are interrelated, repeated monitoring results in waste of construction costs and redundancy of analysis data
