Description
Technical Field
The utility model belongs to the technical field of environmental management, and particularly relates to a test device for simulating the flow of water bodies of urban rivers and lakes.
Background
The essential reason of the black and odorous river is that anaerobic microorganisms in water are greatly propagated in an anoxic state, so that the organic matters are subjected to anaerobic decomposition and a great amount of odor-causing substances such as H are generated 2 S、CH 4 And NH 3 Etc. The objective external factor is that a great amount of domestic sewage is received in the urban river channel, the organic pollution is serious, the metabolism nourishment is provided for anaerobic microorganisms, and on the other hand, the sediment continuously enriched with nutrient substances (N, P and the like) in the river channel provides a temperature bed for the anaerobic microorganisms to reproduce. The traditional river and lake sewage treatment technology comprises sewage interception, dredging, water diversion, aeration and the like, and the methods have obvious short-term effects, but have higher requirements on later-period management, large engineering quantity and need periodic maintenance, and even the phenomenon of black return and odor recovery occurs after dredging the river channel and checking and accepting the river channel.
In addition, the sediment serves as an important place and environment for material exchange in the river ecosystem, and under certain conditions and for a period of time, the pollutant absorbed from the water body can be re-released from the sediment into the water body. The aerobic microorganisms in the water body rapidly consume dissolved oxygen in the water body while utilizing organic matters, and the oxidizing environment is gradually converted into the reducing environment. With the aggravation of the deposit reducing environment, the anaerobic microorganism activity in the water body is enhanced, and organic matters generate organic acid, acidified Volatile Sulfide (AVS) and other black and odor substances in the anaerobic degradation process. Although biological methods are increasingly being used as a green-economic repair method, biological methods have limited effectiveness in severely contaminated water bodies.
Therefore, the influence of the type, the attachment mode and the microbial inoculum consumption of the microbial inoculum on the water quality restoration effect under the existing river hydrodynamic conditions (including surface flood and runoff) is necessary to be researched, so that a reasonable and effective microbial inoculum restoration scheme is provided. The small water environment simulation device in the prior art has the advantages that the structure is simple, the complex water environment is difficult to accurately simulate, the test result deviation is larger, the consideration factors of the medium and large water environment simulation system are relatively more comprehensive, too many device structures are integrated, the medium loading amount is large, the operation is complex, the cost is high, and the device is inferior to the small device from the aspects of economy and test efficiency.
