Abstract

The invention provides a method and a system for cooperatively treating organic waste salt and high-salt organic wastewater by a cement kiln. According to the method and the system, low-temperature evaporation and dehydration is carried out on the high-salt organic wastewater by utilizing waste flue gas waste heat of the cement kiln to prepare a concentrated solution with low water content, then the high-temperature flue gas of the cement kiln is used for carrying out twice incineration on organic matters in the concentrated solution or organic matters in the organic waste salt to generate clean industrial salt, waste gas generated in the process enters a cement kiln system for high-temperature strong alkalization treatment so that secondary pollution of the organic waste salt and the high-salt organic wastewater can be thoroughly eliminated, harmless, reclamation, the energy-saving effect and the low-cost treatment of the organic waste salt and the high-salt organic wastewater are realized, and the friendly environment and safe production is ensured.

Description

technical field [0001] The invention relates to the technical field of waste treatment, in particular to a method and system for co-processing organic waste salt and high-salt organic waste water in a cement kiln. Background technique [0002] Cement kiln co-processing solid waste technology refers to a waste disposal method that achieves the purpose of decomposition, degradation, elimination, inertization and stabilization of toxic components of solid waste through high-temperature incineration and high-temperature sintering process of cement clinker mineralization. It has the technical advantages of wide application range, large consumption capacity, strong adaptability to various wastes, large heat capacity, large thermal inertia and high heat transfer efficiency. At present, the technology of co-processing solid waste in cement kilns has also been developed rapidly. . [0003] High-salt organic wastewater and organic waste salt mainly come from wastewater or by-products...
