What are the reasons that affect the treatment effect of small and medium slaughter sewage treatment equipment? Author: slaughter the main source of water is a series of sewage discharged slaughter process, including: the slaughter wash, rinse disintegration, internal organs wash, rinse the floor and livestock manure wastewater. Sewage contains a large amount of organic matter, the main components are: animal feces, blood, animal visceral debris, animal hair, minced skin and oil, etc.  The main characteristics of sewage are: high concentration of suspended solids, high concentration of organic pollutants, and strong fishy smell. The direct discharge of this kind of sewage will cause serious eutrophication of the surrounding water body, seriously destroy the self-purification ability of the water body, cause the water body to become black and smelly, have a great impact on the environment and affect the health of surrounding residents. According to the nature of slaughter wastewater, the selection of the process of small and medium slaughter wastewater treatment equipment is based on the following ideas:    (1) Use more mature and reliable flotation method, biological contact oxidation method plus sedimentation, and disinfection treatment process; at the same time, use grid interception and sediment separation Auxiliary treatment processes such as oil and sand removal.  (2) The sewage is pretreated first, through the processes of grille interception, sediment oil separation, primary sedimentation, and adjustment tank, so as to stabilize the quality and volume of wastewater and reduce the impact load of subsequent biological treatment.  (3) The effluent containing a small amount of oil is treated by air flotation, hydrolysis acidification, and biological contact oxidation to greatly degrade the organic pollutants in the wastewater.  (4) The waste water after biochemical treatment adopts the physicochemical method, and the suspended solids dropped off in the biochemical process are removed by coagulation and sedimentation.  (5) The effluent after sedimentation is disinfected and discharged according to the design requirements.  (6) The technological process is simple, the project cost is low, the operation is economical, and it is easy to manage.
