Above ground waste water disposal system

摘要

A method and apparatus for disposing of waste water above ground is disclosed. Effluent is deposited in a first tank wherein solids are broken down and liquified by a primary preconditioning unit. The preconditioned effluent is transferred to a second tank. A secondary conditioning unit in the second tank suspends liquid and solid particles in the tank air and vapor, vaporizes the suspended liquid and any entrained solid particulate material, and then discharges the vaporized material into the ambient atmosphere. An automatic control means senses vapor temperature and operates a stack damper and vacuum means which causes the vapor stream, thus preventing escape of non heat-treated vaporized materials. Another automatic control means activate the secondary treatment unit heater only when the liquid level of the second tank is within a preselected range.
