Technical Field

Background
In industrial wastewater such as domestic sewage, food processing and paper making, organic substances such as carbohydrates, proteins, oils and fats, lignin and the like are contained. These substances are present in the sewage in a suspended or dissolved state and can be decomposed by biochemical action of microorganisms. Oxygen is consumed in its decomposition process and is therefore referred to as an oxygen-consuming contaminant. Such contaminants can cause a reduction in dissolved oxygen in the water, affecting the growth of fish and other aquatic organisms. After the dissolved oxygen in water is exhausted, the organic matter is anaerobically decomposed to generate hydrogen sulfide, ammonia, mercaptan and other bad smells, which deteriorates the water quality. The organic matter components in the water body are very complex, and the concentration of the oxygen-consuming organic matter is usually expressed by the oxygen consumption in the biochemical decomposition process of the oxygen-consuming substance in unit volume of water.
Anaerobic biological treatment is a main means for treating high-concentration organic wastewater at present, and various organic matters in the wastewater are converted into gases such as methane, carbon dioxide and the like under the condition of no molecular oxygen by utilizing the combined action of anaerobic microorganisms and activated sludge.
