Improvement of sewage treatment efficiency
The physical and chemical treatment of sewage treatment is inefficient, high cost, complex management, and may cause secondary pollution, so it cannot be a good application and promotion. And the process of recycling the waste water by using a material circulation process of the microbial population. Biological treatment of sewage with high efficiency, low cost, low energy consumption, stable water quality, simple management and so on.
Microorganisms in wastewater treatment systems usually require a certain amount of micro nutrient elements, can make the microbial community rapid growth and reproduction, these micro nutrients are known as microbial “growth factor". If this "growth factor" content is insufficient, it will reduce the efficiency of sewage treatment, and then affect the efficiency of the whole process.
