    Abstract: The invention provides methods and compositions for reducing the malodorous sulfide gas released by a wastewater treatment system. The method preserves the vitality of waste consuming organisms within the system. The method comprises the steps of: determining the SRP PAA demand of the system, determining the aerobic PAA demand of the system, and adding a composition in an amount such that it is in excess of the SRP PAA demand but is below the aerobic PAA demand. Even though the composition increases the amount of sulfates within the wastewater it reduces the amount of SRP which prevents the malodorous sulfite gas release. The composition comprises at least one percarboxyacid.

    Abstract translation: 本发明提供了减少由废水处理系统释放的恶臭硫化物气体的方法和组合物。 该方法保持系统内消耗废物的生物体的活力。 该方法包括以下步骤：确定系统的SRP PAA需求，确定系统的有氧PAA需求，并添加一个量超过SRP PAA需求但低于有氧PAA需求量的组成 。 即使组合物增加了废水中的硫酸盐的量，也减少了防止恶臭的亚硫酸盐气体释放的SRP的量。 组合物包含至少一种过羧酸。
