✦ Synopsis
An experiment has been carried out at a test plant for small-scale sewage that consists of a pretreatment unit, a suspended solid (SS) methanization reactor with a membrane module, and a nitrogen removal unit. After continuous experiments, the SS removal rate in the pretreatment unit was found to be more than 80%. The reduction rate of the volatile suspended solids (VSS) in the SS methanization reactor was 51-79% under temperature conditions of 25-35°C and HRT 4.2-10.2 d, and the effluent from the nitrogen removal unit was stable at BOD of less than 2 mgll and T-N of less than 5 mg/l.
