Description

A kind of electrochemical treatment method for organic wastewater

technical field

The invention belongs to the technical field of organic waste water treatment, and more particularly relates to an electrochemical treatment method for organic waste water.

Background technique

Organic wastewater is wastewater mainly composed of organic pollutants. Organic wastewater can easily lead to eutrophication of water quality and cause great harm. Organic wastewater generally refers to the wastewater above 2000mg/L discharged from the printing and dyeing, papermaking, leather and food industries. Industrial wastewater such as textile printing and dyeing, domestic sewage, food processing and papermaking contains organic substances such as dyes, carbohydrates, proteins, oils, and lignin. These substances are present in the sewage in a suspended or dissolved state and can be decomposed by the biochemical action of microorganisms. Oxygen is consumed in the process of its decomposition, so it is called oxygen-consuming pollutants. This pollutant can reduce dissolved oxygen in the water, affecting the growth of fish and other aquatic life. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobic decomposition, producing unpleasant odors such as hydrogen sulfide, ammonia and mercaptans, which deteriorate the water quality. The composition of organic matter in water is very complex, and the concentration of oxygen-consuming organic matter is usually expressed by the amount of oxygen consumed in the biochemical decomposition of oxygen-consuming substances per unit volume of water.

Many organic waste water that is difficult to decompose needs to be treated by electrolysis, while the ordinary organic waste water electrolysis method is slow to treat sewage, and the sewage is easy to adhere to the electrode plate, which affects the electrolysis speed.
