With the development of the economy, a large amount of domestic sewage and industrial wastewater containing pollutants are discharged into the river, polluting the water environment of the river, damaging the river ecosystem, and ultimately leading to black and odorous rivers. Based on the characteristics of the Black and Stinky River, our company mainly selects the following natural ecological water purification system Fix skills for improvement.

1. Chemical precipitation method

Add flocculants and coagulants to water, allowing it to undergo direct physical adsorption and chemical reactions with pollutants in the water, generating insoluble colloidal precipitates to separate and remove pollutants. However, due to the widespread involvement of a large number of chemical agents in chemical methods, it can lead to secondary pollution and address the symptoms rather than the root cause.

2. River dredging

In order to remove endogenous pollution from the sediment, engineering methods are generally used to dredge and clear the black and odorous rivers. This skill is a powerful means to solve the problem of black and odorous rivers, but due to the high engineering cost, it needs to be applied according to the actual situation.

3. Flow making and aeration skills

Black and odorous rivers are generally sections with poor fluidity and are in low oxygen conditions. In order to enhance the fluidity of water bodies and improve dissolved oxygen in water, flow making or aeration can be arranged to adhere to water circulation and flow, and improve dissolved oxygen in water bodies through exchange at the upper and lower levels.

4. Ecological floating bed skills

The ecological floating bed skill is to use artificial floating bodies, plant aquatic plants on top, purify the water, and inhibit the growth of algae. Using plant roots to provide a favorable growth environment for microorganisms and create a synergistic effect of clean water. This skill is simple to operate, inexpensive, and has a significant effect, and has now been widely applied.

5. Microbial water skills

The central microbial community selected for microbial clean water includes photosynthetic bacteria, nitrifying bacteria, spore forming bacteria, yeast, actinomycetes, etc. It is mainly enriched and screened from the treated river water and sediment, relying on indigenous microorganisms. After compounding and domesticating the microorganisms, it forms a microbial agent with strong resistance to organic pollution. This skill can enhance the microorganisms in clean water, ultimately achieving the ecological function of continuing to clean water.
