River intersection, bifurcated and curved microbial community river model test system and test method
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.
本发明涉及一种河流交汇、分汊及弯曲微生物群落河工模型试验系统及试验方法，包括河道水箱，河道水箱底部铺有取自试验河道的河流底质，河道水箱包括干流河道和若干个支流河道，每个支流河道的上游端均设置有消能槽，干流河道出水口处设有三角堰，河流水经过消能槽均速从各个支流河道交汇于干流河道，再从干流河道出水口流出，给河流底质提供河道模拟环境。试验方法则是使用此系统来得到河流底质中河水中的微生物进行后续试验。将河工模拟试验方法和微生物降解污染物试验方法相结合，进出水口互换不仅对河流交汇区底质微生物群落进行试验，还对分汊河道和弯曲河道底质微生物进行试验，适应多种河道的微生物试验。
