River intersection, bifurcated and curved microbial community river model test system and test method

Abstract

The invention relates to a river intersection, bifurcated and curved microbial community river model test system and test method. The river intersection, bifurcated and curved microbial community river model test system comprises a river channel water tank, a river substrate taken from a test river channel is laid at the bottom of the river channel water tank, the river channel water tank comprises a main river channel and a plurality of branch river channels, and an energy dissipation groove is formed in the upstream end of each branch river channel; and a triangular weir is arranged at a water outlet of the main stream river channel, river water passes through the energy dissipation grooves and converges at the main stream river channel from the branch river channels at a uniform speed and then flows out from the water outlet of the main stream river channel, and a river channel simulation environment is provided for river sediment. According to the test method, the system is used for obtaining microorganisms in river water in a river substrate for subsequent tests. A river engineering simulation test method and a microbiological pollutant degradation test method are combined, the interchange of a water inlet and a water outlet can test substrate microflora in a river intersection area, and further can test substrate microorganisms of a bifurcated river channel and a bent river channel, so that the system is suitable for microbiological tests of various river channels. 22.

Description

technical field [0001] The invention relates to a river engineering model test system and test method for river confluence, branch branching and bending microbial communities, belonging to the technical field of river engineering models. Background technique [0002] my country is a country that lacks water resources, and most places suffer from water shortages, so the research on water pollution control is very important. Water pollution seriously affects the self-purification ability of water bodies and the survival of aquatic organisms and species, leading to species extinction, so water control is imperative. With the continuous advancement of industrialization, water pollution has become an important restrictive factor that worries our survival and economic development. There are chemical, physical and biological methods to control water pollution. The chemical and physical methods of river pollution control have been widely implemented, but the method of microbial pol...

Problems solved by technology

There are chemical, physical and biological methods to control water pollution. The chemical and physical methods of river pollution control have been widely implemented, but the method of microbial pollution control in rivers has limited implementation capacity due to species restrictions, especially for river confluences, branches and bends. There are difficulties in sampling microorganisms here, and there are also problems with the integrity of sampling. There is no device that can solve this problem in the existing solutions, so there is an urgent need for a test system that can be used for river microorganisms.
