T/CPCIF 0131-2021 Pesticide-containing salt organic wastewater resin adsorption treatment technical specifications

Scope

Scope: This document specifies the technical requirements for the entire process of design, construction, acceptance, and operation management of resin adsorption treatment projects for pesticide-containing saline organic wastewater. This document is applicable to resin adsorption treatment projects for pesticide-containing saline organic wastewater and can be used as a technical basis for environmental impact assessments, environmental protection facility design, and construction of pesticide-containing saline organic wastewater resin adsorption treatment projects. Main technical content: 5.1 General provisions 5.1.1 Pesticide-containing saline organic wastewater resin adsorption treatment projects shall be equipped with alarm and emergency systems, and ensure the normal supply of compressed air, steam, process water, and desorption agents before the resin adsorption treatment project is started. 5.1.2 During the operation of the resin adsorption tower, the resin inside the tower should always be kept in a state of being fully immersed in liquid. 5.1.3 Pesticide-containing saline organic wastewater resin adsorption treatment projects mainly include: wastewater resin adsorption buildings and equipment, resin regeneration buildings and equipment, auxiliary projects, and supporting facilities. The design of the electrical system shall comply with the relevant provisions of GB 50052, GB 50054, and GB 50055, and the design of instrumentation piping and wiring shall comply with the relevant provisions of HG 20512. 5.1.4 When using organic solvents for desorption, the desorption solution shall be distilled to recover the organic solvents, and the residual bottom liquid can be disposed of by incineration; when using acid or alkali solutions for desorption, the desorption solution can be treated by oxidation before being sent to the wastewater treatment station.
