Trap and drain assembly for draining waste liquids while blocking odors

The invention provides a flush free drain trap system. The trap of the invention may be used in any trap system intended to block a back flow of odors from the waste line. A sealant liquid floats on top of the waste liquid in the trap to block odors. The trap uses one passageway to pass liquids to the sewer line, similarly to a conventional drain system, for preventing overflow and allowing cleaning. A second passageway allows the trap to dispose of small amounts of the waste liquid though an opening and a valve operated by the buoyancy caused by the accumulation of waste liquid in the trap. In normal use, waste liquid is passed to the sewer line without loss of sealant liquid. Furthermore, the performance of the trap is not affected by the evaporation of the waste liquid when the trap is unused.

Thereafter, a heating member configured proximal to the crucible combusts the mixture of the waste and the calcium carbonate to form one or more of slag and one or more acidic gases. On combustion, the one or more acidic gases are neutralized by calcium hydroxide produced as a result of combusting the calcium carbonate. Additional metal compounds usable as fertilizers are also produced in response to reacting with the one or more acidic gases.

METHOD FOR REDUCING COD OF WASTEWATER WITH IMPROVED UTILIZATION EFFICIENCY OF OZONE

Provided is a method for reducing COD of wastewater with improved utilization efficiency of ozone. The method achieves an objective by adding agents for removing hydroxyl radical scavengers produced by base-catalyzed ozone advanced oxidation to wastewater. The addition of calcium ion, barium ion, etc. to a base-catalyzed ozonation system makes the hydroxyl radical scavengers form precipitates, separated from water and lose the capability of scavenging hydroxyl radicals, thereby enhancing ozone utilization efficiency. Furthermore, calcium ion, barium ion, etc. form precipitates with partial organic acids yielded in the wastewater ozonation and are separated from water, hence diminishing ozone consumption and indirectly improving the ozone utilization efficiency in the wastewater treatment. The present invention can not only significantly enhance the reaction rate and utilization efficiency of ozone, saving reaction time and costs, but also enable complete mineralization of the organic compounds, significantly reducing COD and total phosphorus of wastewater.
