    摘要: Treatment system for wastewater containing ammonium is provided. The treatment system of the present invention includes an ammonia oxidation reactor and a membrane reactor disposed on the back of the ammonia oxidation reactor. The ammonia oxidation reactor includes biological carriers for carrying the ammonium oxidation bacteria and nitrite oxidation bacteria, a pH level controller for increasing the pH level to above 7.5, and a DO (dissolved oxygen) controller for reducing the DO content to less than 1.0 mg/L. The membrane reactor composed of a membrane and an aerator is used to separate the solids and liquids of the effluent of the ammonia oxidation reactor. In addition, a method for treating wastewater containing ammonium is also provided.

    摘要: The present invention disclose a process for treating a wastewater from a foodstuff factory, wherein the pipelines are cleaned and the containers are sterilized by using a water containing peracetic acid as an disinfection agent. The process of the present invention includes aerating or stirring the wastewater to decompose the peracetic acid contained therein, and carrying out an aerobic treatment to decompose the organic compounds in the wastewater. Peracetic acid is in the unstable peroxidation state, and can be decomposed into acetic acid by self-oxidation-reduction. The process of the present invention uses aeration or stirring to trigger the decomposition of the peracetic acid, so that the disinfection function thereof is reduced, and thus the aerobic treatment can be conducted to decompose the organic compounds in the wastewater.
