Water body purification method and system

Abstract

The invention relates to a water body purification method. Through exciting the metabolic activity of a water body local micro flora, promoting the absorbing capability of microorganisms on contaminants in the growth and propagation processes, improving the effective biomass and the functionality of the microorganisms, and recombining, perfecting and optimizing the water body microorganism ecological system, the material flow transfer of organic nitrogen and phosphorus contaminants among different trophic levels of the water body ecological system is realized, the water body self cleaning regulation capability recovery is promoted, and the water quality purification and ecological restoration are realized. A water body indigenous microorganism activation system for realizing the water body purification method comprises an activation reaction region and an accessory equipment region. The activation effect on the water body microorganism flora is obvious; the automation degree is high; the accessory equipment is little; the management operation is convenient; the energy consumption is low; the technical support can be provided for natural landscape water body governing; good social benefits and environmental benefits are realized.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering and relates to a water body purification method and system. Background technique [0002] With the rapid development of economy and society, some surface water bodies have been polluted and damaged to varying degrees, such as serious eutrophication, reduced transparency, and foul odor. Eutrophication is an important manifestation of the current routine pollution of water bodies, that is, a large amount of nutrients such as nitrogen and phosphorus accumulate in water bodies. The balance of the system is unstable, which eventually leads to the destruction of the aquatic ecosystem and the further aggravation of environmental problems. With the increasing use of environmental resources by human beings, especially the large-scale development of industrial and agricultural production, a large amount of domestic sewage containing nitrogen and phosphorus nutrients is discharged into nea...

Problems solved by technology

This process is the same as the traditional air flotation method, but the chemical dosing device is added, a large amount of chloride ion secondary pollution is introduced, and the process is cumbersome

[0006] The traditional biological bypass water treatment process can effectively remove organic C, N, and P in wastewater, but its biological removal mechanism is completed in a closed microbial action unit, and phosphorus removal is mainly completed through sludge discharge. The generation of a large amount of sludge not only causes secondary pollution, but also has extremely high investment and operating costs. How to effectively treat and dispose of a large amount of excess activated sludge has become a bottleneck in the development of modern sewage treatment plants.
