RECYCLABLE SEQUENCING BATCH REACTOR (SBR) SYSTEM FILLED WITH MEDIA CONTAINING ZEOLITE FOR REMOVAL OF ORGANICS, NITROGEN AND PHOSPHORUS FROM SEWAGE AND WASTEWATER

摘要

PURPOSE: A recyclable sequencing batch reactor system filled with media containing zeolite is provided to effectively treat organic matters having high and low concentrations and remove nitrogen and phosphorus in sewage and wastewater, improve the total nitrogen removal ratio and suppress secession of adhered microorganisms. CONSTITUTION: The recyclable sequencing batch reactor system comprises media(100) containing zeolite as a principal ingredient loaded in a sequencing batch reactor(12); a diffuser(17) installed at one side of the inner surface of the sequencing batch reactor; a sensor(19) installed at the other side of the inner surface of the sequencing batch reactor to measure water quality; first and second water level control units(16a,16b) installed at another side of the inner surface of the sequencing batch reactor with being spaced apart from each other in a certain distance; an inner circulation pump(15) installed at upper and lower sides of the sequencing batch reactor; an automatic controller(24) connected to an outlet of the first and second water level control units and the sensor; solenoid valves(18a,18b,18c) connected to an outlet of the automatic controller; and nitrogen feeder(21), oxygen feeder(22) and blower(23) installed at one side of the solenoid valves.
