The difficulty of governance lies not only in solving the existing pollution in the river, but also in nitrification, absorption, and degradation of the invasion of external pollution sources. According to ecological principles, the self purification ability of aquatic animals, plants, and microorganisms is utilized to absorb organic pollutants from water bodies, in order to achieve the goal of water purification. Based on the current domestic and international technologies for treating polluted water bodies in rivers, combined with the principles of investment and price comparison, it is believed that using a combination of microbial and aquatic plant cultivation technology is a more scientific and reasonable approach for treatment, establishing a self purifying ecosystem, and adapting to low-cost and long-term management.

Selected microorganisms（Bacta-Pur XLGThe main components of the series are bioactive enzymes and specially selected microorganisms during the fermentation process. Especially effective in activating and optimizing biological filtration systems, it is used for eutrophication and organic pollution in water, while also degrading sediment and purifying water quality. This microorganism is a biological product formed by isolating, domesticating, and adaptively cultivating advantageous bacterial strains selected from nature, and concentrating and solidifying them in a living state. It has strong adaptability to the environment and stronger ability to decompose pollutants. Belonging to environmentally friendly products, it does not cause secondary pollution, poses no harm to humans and animals, and has passed national toxicity testing. This product has been included in the emergency plan product catalogs of countries such as the United States and Europe（NCP）. This product has patents in many countries such as the United States, the United Kingdom, Italy, Germany, China, and France, and is recommended for use by environmental protection departments in many countries and regions such as the United States, Canada, and Taiwan. The advantage of this product is its strong ability to adapt to the environment and decompose nitrifying organic matter. ifPH=6.5～7.2Water temperature ≥150CThe effect is more pronounced.

Introducing microorganisms into water bodies is a process of decomposing and mineralizing organic matter, regulating water quality, improving transparency, and effectively promoting and improving the migration, transformation, and output of organic matter and nutrients in water. Restoring the self purification ability of river water through the reproduction of microorganisms.
