Abstract
Description
Claims (4)
- A kind of high concentration sludge Anaerobic Digestion technology that mud is carried out the pre-dehydration of machinery is characterized in that, concrete processing step is as follows:1. the spissated technology of mud gravity:The water ratio that the sewage work second pond is discharged is at the excess sludge more than 99%, send into mud gravity concentration basin, mud dependence mud scraper is scraped and is collected gravity concentration basin center, discharge by shore pipe then, by equalizing tank or the storage basin of sludge pumping to the desliming machine room, the water ratio that concentrates back mud is 97%, and supernatant liquor is separated and is back to Sewage treatment systems;
- 2. mechanical dewatering equipment carries out the technology of the pre-dehydration of mud:To send into the dehydration machine room through the mud after the gravity concentration basin concentrates, and dewater by mechanical dewatering equipment, and make moisture percentage in sewage sludge be controlled at 88%~90%, the water after supernatant liquor is handled through washing unit is back to Sewage treatment systems;
- 3. anaerobic sludge digestion CSTR technology:Mud behind filter-press dehydration is squeezed in the CSTR anaerobic digester by sludge pump, keeps that mixture pH carries out anaerobic digestion 7.0 in the reactor under 60 ℃;
- 4. dewatering technology of mud:With sludge pump postdigestive mud is sent in the mechanical dewatering equipment, dewatered again, the final moisture percentage in sewage sludge that generates is 75%.
