Product name：Slaughter sewage treatment equipment

Details

  The production of sewage is an important part of the sewage in the slaughterhouse. It is generally composed of the ground washing water of the slaughterhouse, the washing water of the animal droppings and contents after slaughtering, the cleaning equipment of the slaughtering equipment and the clean water and blood water of the slaughtering workshop. In such wastewater, due to the complex content of various harmful substances, such as foods that are not completely digested, harmful gases, blood, feces, litter, oil, and meat. Among these pollutants, the current pollution index is the blood pollution. Therefore, many treatment methods are aimed at directly eliminating blood pollution. In addition, the pollution of feces also accounts for a large part, and the wastewater generated by the slaughterhouse The emissions are comparable to those of small industrial enterprises in general.

  The biochemical treatment method of wastewater is generally carried out in combination with the physical method of wastewater. The main process flow of integrated slaughter wastewater treatment equipment is wastewater→grid→sand separation oil→solid-liquid separator→regulation tank→hydrolysis acidification tank→primary biochemistry →Zhongshenchi →Secondary biochemical → sand filter pool → clear water pool → wastewater discharge is up to standard. First, the soft fiber, hair, other impurities and sludge left by the fence. On this basis, the sand separation and oil separation treatment is implemented. When the dust and sand is separated, the water should be stored at the same time to ensure that the next step of separating the solid impurities from the wastewater is carried out smoothly.

  After the wastewater is separated, in order to improve its viability, the submersible pump is first used to enhance the physical and chemical treatment of the air flotation device, followed by hydrolysis and acidification to reduce the pH value of the organic acid in the water, thereby simplifying the organic matter. The sludge produced in the domestic sewage treatment can be purified by anaerobic sludge treatment and hydrolyzed and acidified in the hydrolysis acidification tank, so that the sludge production amount of the biochemical treatment of the wastewater can be reduced to a low limit. After hydrolysis and acidification, the sewage is subjected to biochemical treatment of the oxidation system in the primary biochemical pool. After the treatment, the secondary sedimentation is carried out by the intermediate sedimentation tank. After the second biochemistry, the sand filtration, purification and disinfection treatment are carried out, and then discharged to the standard.
