More Information
Summary:An urban sewage treatment device comprises a sewage collection pipe, a slag removal basin, a sand setting basin, an anaerobic basin, an oxidation ditch, a secondary setting basin, a contact disinfection basin, a sludge storage basin, a concentration basin, an extraction basin and a drying and smashing machine, wherein the slag removal basin is communicated with the sewage collection pipe; the sand setting basin is communicated with the slag removal basin; the anaerobic basin is communicated with the sand setting basin; the oxidation ditch is communicated with the anaerobic basin; the secondary setting basin is communicated with the oxidation ditch; the contact disinfection basin is communicated with the secondary setting basin; the sludge storage basin is communicated with the secondary setting basin, the oxidation ditch and the anaerobic basin; the concentration basin is communicated with the sludge storage basin; the extraction basin is communicated with the concentration basin; the drying and smashing machine is communicated with the extraction basin. The urban sewage treatment device can effectively reduce COD and BOD in urban sewage, and meanwhile can remove heavy metals in bottom sludge so as to realize agricultural utilization of the bottom sludge, reduce secondary environmental pollution and increase the resource utilization ratio.
