Embodiment Construction

[0029] Refer to attached figure 1 , 2 , the purification method of the mussel purification system in the eutrophic water body of the lake water source:

[0030] 1. Carry out artificial propagation and strengthen cultivation of pleated crested mussel or triangular sail mussel.

[0031] 2. Choose well-grown pleated crested mussels or triangular sail mussels.

[0032] 3. In the eutrophic waters that need to be purified, establish a water column purification system for mussels, measure the optimal unit elimination of chlorophyll a and suspended solids in the water column system at the corresponding time, and determine the amount in the unit water body The biomass of mussels needs to be set.

[0033] the way is:

[0034] ①Set 5-6 groups of impermeable enclosure water column systems in representative eutrophic waters in lake waters to be purified;

[0035] ②Set mussels with different mussel numbers and gradient biomass in the water column system, and set a group without mussels...

Abstract

A freshwater mussel purifying system in lake nutritive water body and its purification are disclosed. The purifying system consists of pile, float ball, nylon rope and mesh basket. It is characterized building lake pile freshwater mussel purifying system with corresponding time, determining optimum chlorophyll alpha and suspend unit elimination quantity from freshwater mussel, determining living things for freshwater mussel, building a freshwater mussel purifying system engineering in lake water source enriched water body, checking and managing regularly, maintaining complete of engineering structure, collecting mature freshwater mussel regularly, and supplementing young freshwater mussel in engineering area.

Description

technical field [0001] The invention relates to a purification system and purification method for mussels in eutrophic water bodies in lake water sources, and belongs to the bio-purification technology of eutrophic water bodies in lake water sources and the technology of eutrophic water resource utilization. It is also suitable for aquaculture and water purification in eutrophic water bodies such as rivers, beaches, and ponds. Background technique [0002] There are many lakes in my country, 1km across the country 2 There are 275 natural lakes above, with a total area of ​​101km 2 , accounting for 0.5% of the country's land area; 1 / 3 of which are freshwater lakes, mainly distributed in the vast areas of the eastern coast and the middle and lower reaches of the Yangtze River. This area is an economically developed plain with dense population, large water consumption, and unsuitable human activities, which have greatly changed the material circulation and energy flow of the ...
