DUAL VACUUM SEWER COLLECTING SYSTEM FOR SUCKING SEWAGE AND WASTEWATER FROM HOUSES OR FACTORIES THROUGH A VACUUM LINE AND TRANSFERRING SEWAGE TO A COLLECTING CONTAINER OR A WASTEWATER DISPOSAL PLANT
PURPOSE: A dual vacuum sewer collecting system is provided to improve available lift by collecting and transferring sewage with a vacuum pump, and to maintain easily and increase treatment capacity by continuously collecting and transferring sewage with two collecting tanks and two vacuum pumps. CONSTITUTION: A vacuum sewer collecting system sucks sewage or wastewater from houses and factories through vacuum lines, and transfers sewage to a collecting container or a sewage disposal plant. The dual vacuum sewer collecting system is composed of two collecting tanks(21,21') storing sewage through the vacuum line from a sewage pit installed around a sewage system, vacuum pumps(23,23') communicated with the collecting tanks, air lines(40,40',45,45') discharging internal air from the collecting tanks by using the vacuum pumps and injecting external air to the collecting tanks, sewage transfer lines(26,26') connected to the collecting tanks to discharge sewage out of the collecting tanks, and plural control valves(41,42,43,44) installed in the air lines and the sewage transfer lines.
