Problems solved by technology

[0003] The self-purification ability of the river is related to the flow velocity. The construction of the reservoir reduces the flow velocity of the river, which reduces the self-purification ability and causes the water quality of the river to deteriorate.

Embodiment 1

[0035] S1. According to the water depth, it is divided into deep water area, shallow water area and shoal area; according to the water temperature, it is divided into moderate temperature water area and low temperature water area; according to the water flow velocity, it is divided into rapid flow area, slow flow area, winding area and straight area. Detect the N and P content in the water quality through instruments, collect the types and quantities of phytoplankton in different waters, establish long-term monitoring of the number and types of phytoplankton, and accumulate biological data;

[0036] S2. Collect phytoplankton data of hydropower stations in different waters before and after dam construction. Sampling points are sorted in order from upstream to downstream and from far to near relative to the hydropower station. According to the formula Calculate the carbon flow, where is the carbon flow of phytoplankton in the river, in mg / s; is the river flow, in L / s; is t...

Embodiment 2

[0041] Embodiment 2: embodiment 2: based on embodiment 1 but different is;

[0042] The large-aperture intercepting device includes a floating plate 1, a large-aperture intercepting net 2 and a fixed column 9, and also includes a mounting plate 4 and a positioning anchor 6. Thread groove 18 is set, thread groove 18 is matched with fixing screw 12, and the upper surface of floating plate 1 is evenly provided with clamping nut 10, and the two sides of described large-aperture interception net 2 are fixedly connected with fixed rod 8, and the large-aperture interception net 2. The upper end is uniformly provided with clamping screws 11, the clamping nuts 10 are matched with the clamping screws 11, the lower end of the large-aperture intercepting net 2 is fixedly connected with the mounting plate 4, and the top of the fixing rod 8 is fixed to the lower surface of the floating plate 1. Connection, the lower end of the fixed rod 8 is fixedly socketed inside the positioning block 3, ...

Embodiment 3

[0044] Embodiment 3: based on embodiment 1 and 2 but different is;

[0045] Carbon-fixing organisms include aquatic economic animals and submerged plants that reproduce and proliferate naturally; said aquatic economic animals include fish, shrimps, crabs, and shellfish; It is harvested once a year, while other animals and plants except fish are harvested every 3-4 months.

[0046] In this example, the plankton in the water body before and after the dam construction of the hydropower station is selected as the research object, and the carbon fixation function of aquatic carbon-fixing organisms is used to promote the biological absorption and fixation of natural bait in the water body through the proliferation and symbiosis of aquatic economic animals and submerged plants. The carbon in the water body is used to jointly build an aquatic biome with high carbon sequestration capacity, so as to balance the carbon flow of the water body, harvest and salvage regularly, and reduce the...

Abstract

The invention relates to a method for regulating and controlling the carbon flow of phytoplankton. With phytoplankton as an example, by calculating the carbon flow of phytoplankton, regulation and storage of water reservoir are carried out according to relevant factors of carbon flow formation of phytoplankton so as to generate a man-made flood peak, a large-aperture interception device and a stirring device are arranged below a water source, the interception device can effectively intercept off large solid waste and floating objects, and decrease the impact strength to the stirring device, and meanwhile the stirring device can stir a water body and make the water body dissolve plenty of oxygen and undergo sufficient illumination for eliminating anaerobic reaction. Carbon fixation organisms are thrown into the water body reasonably for promoting absorption of natural food organisms in the water body and fixing carbon in the water body, so that the carbon flow is as close as possible toa value before dam construction.

Description

technical field [0001] The invention relates to the field of water body environment regulation, in particular to a method for regulating phytoplankton carbon flow. Background technique [0002] The most direct impact of hydropower development is the water ecosystem. If it is not developed properly, it will affect the structure and function of the water ecosystem, and then affect sustainable development. The influence of water ecology includes the influence of environmental factors and the influence of species factors. Environmental factors refer to the morphological characteristics of the river itself, including water quality, hydrological regime, habitat and other factors. Species factors refer to the species based on rivers, including fish, phytoplankton, zooplankton and other factors. [0003] The self-purification ability of the river is related to the flow velocity. The construction of the reservoir reduces the flow velocity of the river, which reduces the self-purifi...
