Characteristics of sewage station: 1, can treat domestic sewage and its similar organic wastewater.2. Adopt anti-corrosion performance materials, with excellent characteristics such as corrosion resistance and aging resistance.3. The complete set of devices is simple to construct, easy to operate, and has various convenient installation forms.4. Convenient management and maintenance, and most of the equipment is equipped with an automatic control system.
Introduction of common treatment process of small sewage station: MBBR fluidized bed biofilm method. The principle of MBBR process is the basic principle of biofilm method. By adding a certain amount of suspension carrier to the reactor, the biomass and biological species in the reactor are improved, so as to improve the processing efficiency of the reactor. Because the packing density is close to water, it is completely mixed with water when aeration, and the environment for microbial growth is gas, liquid and solid. The collision and shear of the carrier in water makes the air bubbles smaller and increase the utilization rate of oxygen. In addition, each carrier has different biological species inside and outside, growing some anaerobic bacteria or concurrent oxygen bacteria inside, the outside is a good nourishing bacteria, so that each carrier is a micro-reactor, so that the nitrification reaction and denitrification reaction exist at the same time, thus improving the treatment effect. Advantages: Compared with the activated sludge method and the fixed packing biofilm method, MBBR not only has the high efficiency and operation flexibility of the activated sludge method, but also has the characteristics of the traditional biofilm method of impact load resistance, long mud age and less residual sludge. Disadvantages: 1. Easy to appear local packing accumulation phenomenon. However, it can be improved by improving the arrangement of the aeration pipeline and the structure of the reactor.2. Grid plate or grid net is easy to cause blockage. However, movable grids can be set, regular manual cleaning can be performed, or air backflow device can be set to prevent blockage.
