Frame type microorganism substratum fixing device

Abstract

The invention discloses a frame type microorganism substratum fixing device, and belongs to the field of design of environmental engineering, ecological engineering and hydraulic engineering. The frame type microorganism substratum fixing device comprises frame type fixing modules, substratum fixing hanging rings, module connecting devices and fixing devices. The frame type fixing modules are connected into a frame through the module connecting devices. The substratum fixing hanging rings are arranged in the middles of beams of the frame type fixing modules and used for fixing substratum. The fixing devices are used for fixing the frame. By means of the frame type microorganism substratum fixing device, river way microorganism biofilm culturing can be promoted so that microbial communities can be formed, the stability of a biofilm culturing system is improved, the device can not be influenced by river way water body transparency, and therefore the problems that a river way gets black and odorous and a water body is deteriorated can be effectively solved, the purifying capacity of the water body is enhanced, and the river way water body reaches the surface water standard.

Description

technical field

[0001] The invention relates to the fields of environmental engineering, ecological engineering and water conservancy engineering design, in particular to a frame-type microorganism attachment base fixing device. 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 country. Black and odorous rive...
