In terms of reducing the harmfulness of disinfection by-products, MBR can ensure that the production of halogenated hydrocarbons is reduced. If the residual chlorine in water is exhausted, the content of halogenated hydrocarbons will not change. Moreover, the concentration of total halogenated hydrocarbons, monobromodichloromethane and trichloromethane will be reduced, which will reduce the persistent and potential hazards to the environment and human health. Therefore, the use of MBR process can not only ensure the reduction of disinfectant dosage, but also minimize the impact of disinfection by-products on human health and ecological environment, which can be fully utilized in hospital sewage treatment.
In the application of MBR process in hospital sewage treatment, the actual characteristics and conditions of hospital sewage treatment should be taken into account. At the same time, its working principle should be correctly grasped. The advantages of MBR process, such as removing sewage pollutants, saving disinfectants, reducing the cost of disinfection process, reducing disinfectant residues and disinfection by-products, should be fully brought into play. Only in this way can we bring more benefits to human health and ecological environment, and promote the healthy and sustainable development of hospitals.
