A new technology for microbial degradation of sewage

Recently, a new technology for microbial degradation of sewage through the Henan Provincial Science and Technology Agency experts identified the main indicators of wastewater treated by this method to meet national standards and farmland irrigation standards, can water trees and flowers.

The technology invented by Luoyang Northern Environmental Engineering Research Institute of Henan Province adopts a multi-level biochemical treatment process and consists of a biological septic tank body, a microbial population, and a microbial carrier. The entire system is buried in the ground. After the sewage enters the system, it does not require any energy consumption. The fluid siphon technology is used to automatically purify the internal structures through successive adjustments, sedimentation, separation, multi-stage biological treatment, and multi-stage oxidation and clarification processes. . The GSH microbial population is added to the system and can be operated for life with a single addition. The microbial population contains many bacteria, wide spectrum, and strong ability to degrade organic matter. The system is equipped with a special GSH biological carrier to facilitate the conjunctiva and metabolism of the microorganisms. When impacted by sewage, the population of microbial bacteria will not be drained.

This technology is suitable for use in areas and places below 0.6 meters underground and at temperatures not lower than 5 degrees Celsius. Compared with similar technologies at home and abroad, it has a one-time investment reduction of about 30%, operating costs reduced by 50%-70%, processing efficiency increased by 3-5 times, and the treated sewage can realize the advantages of resource reuse. Experts believe that the devices supported by this technology are easy to implement and can be mass produced with high economic, social and environmental benefits.
