Culture wastewater treatment device

Abstract

The invention discloses a culture wastewater treatment device. The culture wastewater treatment device comprises a reaction tank, a stirring machine, MBR (membrane bioreactor) diaphragms and an aeration disc, wherein the reaction tank is connected with a sewage intake pipe; the MBR diaphragms are arranged around the inner side of the reaction tank; cellosilk on each MBR diaphragm is hollow cellosilk modified by quinonyl; a water drain pipe is arranged at the upper end of each MBR diaphragm, and is connected with a water pump; the aeration disc is arranged at the bottom part of the reaction tank, and is connected with a fan through a pipeline; the stirring part of the stirring machine is arranged at the center of the sewage of the reaction tank; the aerobic bacteria and anoxic bacteria canalternatively react with the sewage in the reaction tank. The culture wastewater treatment device has the advantages that by arranging the MBR diaphragms with the quinonyl in the reaction tank, the aerobic and anaerobic conditions are alternatively run by adjusting the technology of the reaction tank under the catalyzing function of the quinonyl, the microorganisms in the reaction tank can complete denitrification reaction under the anaerobic condition, the microorganisms in the reaction tank can complete nitrification reaction under the aerobic condition, the purpose of quickly removing nitrogen at high speed is realized, and the quality index of the drained water is stable.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a breeding wastewater treatment device. Background technique [0002] In recent years, with the economic growth and the improvement of people's living standards, the poultry breeding industry based on the large-scale breeding model has developed rapidly. However, the development of livestock and poultry farming has also brought a series of environmental problems. The wastewater produced by large-scale livestock and poultry breeding sites is relatively large and concentrated, and has a high concentration of pollutants. If it is directly discharged into the environment or for agricultural use without treatment, it will cause serious pollution to the ecological environment and farmland, and cause serious damage to livestock, poultry, livestock products, and human beings. serious hazard to their own health. At present, the pollutants discharged by the livestock and pou...
