Abstract

processo de tratamento de resíduos sólidos centrado em procedimentos de sinterização e pelotização. processo de tratamento de resíduos sólidos centrado concentrado em procedimentos de sinterização e pelotização. depois que os resíduos sólidos de várias fontes são classificados e submetidos ao pré-tratamento correspondente, a escória de pré-tratamento gerada pelo pré-tratamento entra nos procedimentos de sinterização e pelotização para tratamento final; ao mesmo tempo, os gases residuais gerados no processo de pré-tratamento podem ser coletados em gás de combustão de sinterização para purificação colaborativa, as águas residuais geradas por pré-tratamento adicional e as águas residuais geradas nos procedimentos de sinterização e pelotização são submetidas a um tratamento útil de extração de sal de águas residuais, o tratamento de processo completo de vários resíduos sólidos é finalmente alcançado e o efeito dos resíduos sólidos no meio ambiente e o risco de poluição secundária são completamente eliminados.solid waste treatment process centered on sintering and pelletizing procedures. solid waste treatment process focused on sintering and pelletizing procedures. after solid waste from various sources is classified and subjected to corresponding pre-treatment, the pre-treatment slag generated by pre-treatment enters the sintering and pelletizing procedures for final treatment; At the same time, the waste gases generated in the pretreatment process can be collected into sintering flue gas for collaborative purification, the wastewater generated by additional pretreatment, and the wastewater generated in the sintering and pelletizing procedures are subjected to a useful wastewater salt extraction treatment, the complete process treatment of various solid waste is finally achieved, and the effect of solid waste on the environment and the risk of secondary pollution are completely eliminated.
