Embodiment

[0039] Such as figure 1 with 2 As shown, a method for in situ domestication of microorganisms adapting to rapid water flow, comprising the following steps:

[0040] (1) Diversion dam setting: the diversion dam 1 is set on the side of the river to isolate the domestication area and guide part of the river water into the domestication area;

[0041] (2) Construction of the water inlet weir: the water inlet weir 2 is set at the most upstream of the domestication area to control the water intake of the domestication area;

[0042] (3) Aeration device setting: the aeration device 3 is set downstream of the water inlet weir, and is used to control the dissolved oxygen in the river in the domestication area;

[0043] (4) Construction and fixation of the microbial attachment base module: the microbial attachment base module 4 is fixed downstream of the aeration device 3 to provide carriers for microorganisms;

[0044] (5) Delivery of microbial preparations: The microbial preparatio...

Abstract

The invention discloses a modular microorganism in-situ domestication method adaptive to a fast water flow, belonging to the fields of designs in environmental engineering, ecological engineering and hydraulic engineering. The modular microorganism in-situ domestication method adaptive to the fast water flow mainly comprises the following steps: (1) flow guide dike arrangement, (2) water inlet weir construction, (3) aeration device arrangement, (4) microorganism adhesion substance module construction and fixation, and (5) microorganism preparation throwing. According to the method, domestication areas are delimited, water flow gradient and dissolved oxygen gradient are changed, and advanced in-situ domestication is performed on river microorganisms step by step, so that then adaptation time of the microorganisms is reduced when the microorganisms are transplanted to the same riverway for ecological restoration, the survival rate of the microorganisms is increased favorably, and a microorganism purification effect is enhanced.

Description

technical field [0001] The invention relates to the fields of environmental engineering, ecological engineering and water conservancy engineering design, in particular to a method for in-situ domestication of modular microorganisms adapted to rapid water flow. Background technique [0002] Rivers are rich in water, water conservancy and aquatic resources, and also have the functions of maintaining biodiversity, regulating climate, storing floods, regulating surface runoff, and ecologically restoring water quality. However, with the rapid development of industry and agriculture in our country, the acceleration of urbanization and the low-level and extensive economic development model, the discharge of industrial wastewater and domestic sewage is increasing, and a large amount of nutrients continue to flow into rivers, which has caused adverse effects on many rivers. Black and odorous rivers have become a common pollution problem in small and medium-sized rivers in cities in my...
