Abstract

a presente invenção refere-se ao campo de tratamento de águas residuais e descreve aparelhos e métodos para o tratamento de águas residuais contendo sais de amônia, que contêm nh4+, so42-, cl- e na+. no método da presente invenção, o valor de ph da água residual a ser tratada é ajustado antecipadamente em uma faixa específico; obtém-se primeiro por evaporação o cristal de sulfato de sódio e amônia relativamente concentrada, e depois obtém-se por segunda evaporação o cristal de cloreto de sódio e amônia relativamente diluída; alternativamente, o cristal de cloreto de sódio e a amônia relativamente concentrada são obtidos por terceira evaporação, e depois o cristal de sulfato de sódio e amônia relativamente diluída são obtidos por quarta evaporação. o método da presente invenção pode recuperar amônia, sulfato de sódio e cloreto de sódio das águas residuais, respectivamente, para que os recursos na água residual possam ser reutilizados, tanto quanto possível.
