TREATMENT SYSTEM AND TREATMENT PROCESS FOR REMOVING HARDNESS, SILICON, AND TURBIDITY FROM WASTEWATER HAVING HIGH SALT CONCENTRATION

摘要

A treatment system for removing hardness, silicon, and turbidity from wastewater having a high salt concentration, comprising an integrated reaction apparatus and a membrane separation apparatus, wherein the integrated reaction apparatus comprises a reaction box (1) and a chemical drug adding device (2); the membrane separation apparatus comprises a membrane pool (6) and a membrane component (7). The wastewater having the high salt concentration enters the reaction box (1); a required chemical drug is added to the wastewater by means of the chemical drug adding device (2); the chemical drug and the wastewater are fully mixed and react to produce different kinds of sludge particles; a sludge particle mixed liquid directly enters the membrane pool (6); under the action of an aeration device (8), sludge is in a suspension state and uniform in concentration, and is screened and filtered by the membrane component (7); produced water is discharged from the membrane pool (6), and intercepted sludge particles are discharged from the membrane pool (6). Also disclosed is a treatment process for removing hardness, silicon, and turbidity from wastewater having a high salt concentration.
