Method for synergistic purification of polluted water by microorganisms and aquatic plants

Abstract

The invention relates to the technical field of polluted water body improvement, and discloses a method for microorganism and aquatic plant cooperative purification of a polluted water body; the method comprises the following steps: A, the tube interior of a microorganism slow-release tube is filled with a compound microorganism preparation; B, the microorganism slow-release tube is applied in the polluted water body or bottom mud by aquatic plants; and C, along with the growth of the aquatic plants, microorganisms in the microorganism slow-release tube are gradually released and are attached to submerged plants, and a biofilm is formed. The microorganism and aquatic plant cooperative purification of the polluted water body is adopted. The microorganism slow-release tube filled with the compound microorganism preparation is adopted, on one hand, stability and washing resistance are greatly improved, on the other hand, the load capacity of microorganism bacteria and the proliferation of the microorganism bacteria are improved, and in general, the purpose of increasing the efficiency of wastewater treatment is achieved.

Description

technical field [0001] The invention relates to the technical field of improving polluted water bodies, in particular to a method for synergistically purifying polluted water bodies with microorganisms and aquatic plants. Background technique [0002] With the rapid development of my country's economy, my country's water environment problems have become increasingly prominent, and urban and rural water environments have encountered unprecedented threats. Surveys have shown that more than 90% of the rural water ecology in the Yangtze River Delta region has lost its basic functions, urban and rural rivers have been severely degraded due to pollution and ecosystems, and the water quality of the rivers has basically fallen into Class V or worse. Most rivers are seriously polluted, rich Nutritization, the main pollution index is potassium permanganate index (COD Mn ) and ammonia nitrogen, in addition, most of the river water turned black and smelly, and the pathogenic bacteria e...

Problems solved by technology

However, whether these products are tablet, powder or liquid, they have great limitations, that is, they can only be used in closed waters with a water depth of no more than 2 meters, and there is nothing they can do when they encounter flowing waters or lake cage culture. , because the water flow will dilute the beneficial bacteria, and the dominant bacteria cannot be formed to achieve the purpose of reducing pollution

Therefore, the effect of this new technology is greatly limited. The beneficial live bacteria microbial water purifier has been unable to be used in rivers, lakes, cage culture and water pollution control in flowing waters since it came out 5 years ago.

[0005] In addition, some prior art products completely rely on chemical cross-linking to adsorb microorganisms on the surface of the carrier, which is expensive to produce and has poor slow-release effect. They can only be used in small water bodies such as ornamental fish or landscape water, and are not suitable for large areas. flowing waters
