摘要
在污水处理中,固体碳源是制约生物反硝化脱氮的重要因素。天然固体碳源有着丰富的来源,但是机械强度低;人工合成固体碳源有很好的物理性质,但是造价较高;天然高分子材料经过改造后具有价格低、物性好的优点,因而成为研究的热点,且具有很好的市场前景。
Solid carbon source is considered as an important factor to restrict the biological deni- trification in sewage treatment. The research and development of solid carbon source recently are reviewed. The carbon source of natural raw is abundant in nature but with low mechanical strength, while the synthetic ones possess good physical property with high cost. The modified nat- ural polymer materials with low price and good physical properties, have attracted much attention, the market prospect is good.
