Functional microorganisms for sewage treatment

1. Physical method: It mainly uses physical action to separate the insoluble substances in the sewage, and does not change the chemical properties in the treatment process. It is used in villages and towns with large water volume, strong self purification capacity and low requirements for sewage treatment.

2. Biological method: use the metabolism function of microorganisms to decompose and oxidize the dissolved or colloidal organic substances in the sewage into stable inorganic substances, so as to purify the sewage. The degree of biological treatment is higher than that of physical treatment. Wastewater biological treatment technology is favored by people because of its obvious advantages such as low consumption, high efficiency, low cost, convenient and reliable process operation and management, and no secondary pollution.

3. Chemical method: it is a method to treat or recover the dissolved or colloidal substances of sewage by chemical reaction, and is mainly used for industrial wastewater. The chemical treatment method has good treatment effect and high cost. It is mostly used as the effluent after biochemical treatment for further treatment to improve the effluent quality.

Microbial treatment

However, with the development of industry, the composition of sewage has become more and more complex. Some organic substances and toxic substances that are difficult to degrade need to be treated by microbial methods. The sewage has the conditions for microbial growth and reproduction, so microorganisms can obtain nutrients from the sewage, and degrade and use harmful substances at the same time, so that the sewage can be purified.

Due to the disadvantages of traditional treatment methods, such as high cost, complex operation, and difficult treatment of harmful pollution with large flow and low concentration, biological treatment technology has attracted increasing attention after years of exploration and research.

Functions

1. It can quickly degrade organic and harmful substances. Through the massive reproduction and metabolic products of functional microorganisms in the product, it can quickly and effectively degrade organic matters in water, and decompose ammonium nitrogen, nitrite, sulfide, phosphorus and other harmful substances.

2. It can purify and improve water quality. Through the reproduction of functional microorganisms and their metabolites in the product, it can eliminate or greatly reduce the sedimentation of the water bottom, purify and improve the water quality, and maintain the ecological balance of the water environment.

3. It can effectively inhibit pathogenic bacteria. High efficiency and high activity functional microorganisms in the product multiply in large numbers to form a dominant flora, which greatly inhibits the growth and reproduction of pathogenic microorganisms.

As the main degradation group in the biological world, microorganisms have achieved remarkable results in the treatment of water pollution, solid waste pollution, heavy metal pollution, compound pollution, oil and air pollution, and are not easy to cause secondary pollution. They are widely used and play a huge role in the field of environmental pollution treatment.
