What are the working procedures of sewage treatment equipment in small hospitals? Author: sewage treatment equipment is the primary means of treatment of sewage, many industries are using wastewater treatment equipment, sewage treatment equipment but because of all medium and large equipment, large area, daily maintenance is also more trouble. Environmental protection company launched a small hospital sewage treatment equipment, this equipment not only has a small footprint, is more convenient to store, and is easier to operate and maintain. It is a good helper for hospitals and factories in sewage treatment. Here is a brief introduction to the working principle of sewage treatment equipment in small hospitals. The sewage flows into the sewage conditioning tank after removing floating and large suspended impurities through the grille. The sewage in the conditioning tank is increased by the pump to enter the small hospital sewage treatment equipment. The sewage undergoes the treatment processes of hydrolysis acidification, biological touch oxidation, and sedimentation in the equipment, and the water is discharged. Qualified to be discharged into the municipal sewer. The sedimentation sludge generated in the sedimentation tank is transported to the sludge tank in the small hospital sewage treatment equipment by the air stripping method. The sludge is concentrated, settled and digested in the sludge tank, and the supernatant is returned to the conditioning tank for reprocessing at the same time as the original wastewater. Concentrated sludge is pumped and transported by manure truck at regular intervals (about once every six months). The small-scale hospital sewage treatment equipment is equipped with fillers in the contact oxidation tank. The lower part is equipped with an aerator, and an aeration system is made of ABS engineering plastic pipes. The air source of the aeration system is supplied by a specially equipped fan. The upper part of the sedimentation pool of the small hospital sewage treatment equipment is equipped with an adjustable water weir to adjust the water level; the lower part is equipped with a cone-shaped sedimentation area and sludge stripping equipment. The air source is supplied by a fan, and the sludge is transported to the sludge pool by means of air stripping. . The residence time of sludge in the sludge tank is about 60 days. The sludge generated by the deposition of the system is discharged into the sludge tank by air stripping, where the sludge is thickened, settled and stored. An aeration pipe is set at the bottom of the tank to prevent the anaerobic digestion of the sludge from generating biogas, and oxidize the sludge to reduce the total amount of sludge. Concentrated sludge is pumped and transported by manure trucks regularly. The upper part of the sludge tank is equipped with a supernatant backflow device to make the supernatant overflow to the acid hydrolysis tank. The above content is the working principle of sewage treatment equipment in small hospitals. Through the introduction of this article, we can also see that the working principles of sewage treatment equipment in small hospitals and large sewage treatment equipment are basically the same. Compared with large and medium-sized sewage treatment equipment, small hospital sewage treatment equipment is more suitable for use by relatively small-scale enterprises
