T/CPCIF 0132-2021 Dye organic wastewater granular activated carbon adsorption treatment technical specifications

Scope

Scope: This document specifies the technical requirements for the design and operation management of dye organic wastewater treatment projects using granular activated carbon adsorption technology. This document is applicable to granular activated carbon adsorption treatment projects for dye organic wastewater, and can be used as a technical basis for the design, operation, and management of granular activated carbon adsorption treatment projects for dye industry organic wastewater. Main technical content: 5.1 General provisions 5.1.1 Dye organic wastewater should be collected and treated separately, and classified for reuse. 5.1.2 The effluent from the granular activated carbon adsorption treatment process for dye organic wastewater should meet the requirements for the intake of the next treatment system. 5.1.3 Before conducting process design, it is recommended to conduct small-scale and medium-scale experiments on the wastewater to determine the treatment efficiency. If there are no experimental conditions, the treatment efficiency should be determined according to HJ 2036. 5.1.4 The granular activated carbon adsorption treatment projects for dye organic wastewater must be equipped with alarm and emergency systems, and heat recovery facilities should be reasonably set up according to the situation of residual heat generated during the regeneration of activated carbon. 5.1.5 In the granular activated carbon adsorption treatment projects for dye organic wastewater, multi-stage regeneration furnaces should be designed to operate in a micro-negative pressure state to avoid the escape of harmful gases. The regeneration furnaces should be equipped with explosion-proof doors or other explosion-proof facilities. 5.1.6 Pre-treatment facilities such as coagulation sedimentation or filtration should be set up before the granular activated carbon adsorption treatment process to meet the requirements of Section 4.2. 5.2 Process composition 5.2.1 The granular activated carbon
