Abstract

The invention provides a method for treating high-concentration salty waste water and waste residue at low cost. The method is characterized by comprising a step 1 of mixing high-temperature smoke generated by burning of the waste residue with atomized waste water, and separating out water vapor smoke; a step 2 of separating out smoke through condensing of the water vapor smoke; a step 3 of subjecting the smoke to secondary burning, waste heat recovery, rapidly quenching treatment and purification treatment, and discharging the treated smoke. The method and the device thereof can simultaneously treat the waste residue and the waste water, and the treatment cost is low.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a low-cost treatment method and device for high-concentration saline wastewater and waste residue. Background technique [0002] With the development of industry, there is an increasing amount of high-concentration refractory organic waste residues and liquids discharged from pharmaceutical, chemical and other industries. If they are discharged without treatment, they will cause serious pollution to the environment. The main components of the waste residue and liquid are usually: saturated salt, some organic matter and the like. [0003] Although the traditional treatment technology can effectively remove COD, N, P and other pollutants in the waste liquid, it consumes more energy and resources during the treatment process, which is actually "dissipating energy with energy". In addition, A large amount of residual sludge is also produced. It can be seen that thi...
