Example Embodiment
[0037] Specific embodiment 1:
[0038] Such as figure 1 Shown is a flowchart of the repair method of the present invention.
[0039] In this example, a certain river is selected for in-situ ecological restoration of dominant microorganisms according to the method of the present invention. The pollution of the river is mainly caused by the discharge of domestic sewage from surrounding residents. Before the restoration, the river is seriously polluted and the water quality is nutritious. Algae grows excessively, the river water is muddy, black and smelly.
[0040] The specific steps are:
[0041] (1) Measure the environmental parameters of the river gushing water: the total length of the water body, the width of the water body, the depth of the water body, the velocity of the water body, and the thickness of the sediment. The velocity of the water body is at the water surface, 1 / 2 water depth, 1 / 4 water width, 1 / 2 The average value of the water velocity at the water width. In this exa...
Example Embodiment
[0069] Specific embodiment 2:
[0070] In this example, the COD of the selected river is 260mg / L, which belongs to the range of COD≧250mg / L, and the dosage of solid bacteria is 200g / m 3 .
[0071] The specific ecological restoration method is the same as that of specific example 1. The difference is that in this example, COD≧200mg / L, that is, the water body is polluted heavily. After the solid bacterial agent is put in, an immersed underwater microbial water cycle needs to be added. Processing box, such as figure 2 Shown are the structural schematic diagrams of the submerged underwater superior microbial water circulation treatment tank of the present invention.
[0072] The submerged underwater superior microbial water cycle treatment tank 100 is immersed in contaminated water, and includes a first tank 110, a second tank 120, a third tank 130, and a fourth tank 140 that are connected in sequence for the contaminated water to enter and The waterway system 150 that flows between th...
