Abstract

The invention discloses a treatment system and a treatment method of organic waste water. The treatment system includes: a water collecting tank which is used for storing organic waste water and feeding the organic waste water; an oxidizing reaction tank which is connected to the water collecting tank and is used for removing organic substances in the waste water; a first pH adjusting tank which is connected to the oxidizing reaction tank and is used for adjusting pH value of the waste water; a micro electrolytic reaction tank which is connected to the first pH adjusting tank and is used for removing chemical oxygen demand and chromatism in the waste water; and a mixing tank. a second pH adjusting tank, a slow mixing tank, a sedimentation tank, an intermediate tank and an SBR tank which are connected successively following the micro electrolytic reaction tank. The system has advantages of high processing efficiency and capability of processing organic waste water on a large scale.

Description

technical field [0001] The invention relates to a waste water treatment system, in particular to an organic waste water treatment system and a treatment method thereof. Background technique [0002] Organic wastewater is wastewater mainly composed of organic pollutants. Organic wastewater is likely to cause eutrophication of water quality and is relatively harmful. Whether it is domestic sewage or industrial wastewater such as food processing and papermaking, it is rich in organic substances such as carbohydrates, proteins, oils, and lignin. Decomposition requires oxygen consumption during the decomposition process, so it is called oxygen-consuming pollutants. This pollutant can reduce dissolved oxygen in water and affect the growth of fish and other aquatic organisms. Once dissolved oxygen in water is exhausted, Organic matter will begin to undergo anaerobic decomposition, producing unpleasant odors such as hydrogen sulfide, ammonia and mercaptans, and deteriorating water ...
