Rapid purifying equipment and method based on black odor water treatment

Abstract

The invention discloses rapid purifying equipment and method based on black odor water treatment. The equipment comprises a sedimentation device, a filtering device and a sterilization purification device; and the filtering device is fixedly installed at the top of the sterilization purification device, the sedimentation device is fixedly installed at one side of the sterilization purification device, and the sedimentation device is composed of a recovery tank, a filter basket, a magnetic filter plate, a sedimentation tank, a coagulant placement barrel, a material falling threaded rod and a material falling motor. According to the equipment provided by the invention, a coagulant is a substance which can bond and aggregate colloidal particles in water, and the coagulant can decolorize the sewage and remove suspended matter; cleaning is performed by a circular filter plate located in the filtering device to prevent impurities from affecting filtration; odor can be removed by activated carbon; a purifying agent is conveniently and uniformly dispersed into the sewage through a hollow stirring main shaft located in the sterilization purification device, the purifying agent and the sewage are fully mixed through a stirring auxiliary shaft, so that the mixing efficiency of the purifying agent and the sewage is improved, and the purifying efficiency of the sewage is improved; and the purified sewage is sterilized by ultraviolet germicidal lamps.

Description

technical field [0001] The invention relates to the technical field of treatment of black and odorous water bodies, in particular to a rapid purification device and method based on the treatment of black and odorous water bodies. Background technique [0002] Black and odorous water body is that when the water body is severely polluted by organic matter, the aerobic decomposition of organic matter will cause the oxygen consumption rate in the water body to exceed the rate of reoxygenation, resulting in anoxic water body, resulting in incomplete degradation of organic matter and slowed down rate, and the anaerobic biodegradation process will generate sulfuration Hydrogen, amines, ammonia, mercaptans and other odorous substances form black substances such as FeS and MnS at the same time, causing black and odorous water bodies. Black and odorous water bodies are serious water pollution phenomena that completely lose the use of water bodies and affect landscapes and humans. Life...

[0002] Black and odorous water body is that when the water body is severely polluted by organic matter, the aerobic decomposition of organic matter will cause the oxygen consumption rate in the water body to exceed the rate of reoxygenation, resulting in anoxic water body, resulting in incomplete degradation of organic matter and slowed down rate, and the anaerobic biodegradation process will generate sulfuration Hydrogen, amines, ammonia, mercaptans and other odorous substances form black substances such as FeS and MnS at the same time, causing black and odorous water bodies. Black and odorous water bodies are serious water pollution phenomena that completely lose the use of water bodies and affect landscapes and humans. Life and health, so it is important to the treatment of black and odorous water. The existing purification technology cannot recover and concentrate the metal particles in the sewage, and cannot evenly sprinkle coagulant into the sedimentation tank. Rapid decolorization and removal of suspended solids in sewage, unable to fully mix the purifying agent with the sewage, unable to improve the mixing efficiency of the purifying agent and sewage, unable to improve the efficiency of sewage purification, and unable to sterilize the purified sewage
