Scope

Scope: This document describes the terminology and definitions, evaluation index system, and implementation plan for the near-zero discharge evaluation of wastewater in chemical parks. This document is applicable to the near-zero discharge evaluation of wastewater in chemical parks. Chemical enterprises not included in the park management can refer to this document for implementation. Main technical content: The evaluation index system for near-zero discharge of wastewater in chemical parks includes five first-level indicators, namely infrastructure indicators, resource consumption indicators, pollution discharge indicators, material cycle indicators, and environmental management indicators. a) Infrastructure indicators include centralized wastewater treatment facilities and centralized hazardous waste treatment facilities in the park. b) Resource consumption indicators include fresh water consumption per unit output value, energy consumption per ton of wastewater treatment and purification, benzene compound consumption per unit output value, and alcohol compound consumption per unit output value. c) Pollution discharge indicators include organic wastewater discharge per unit output value, inorganic wastewater discharge per unit output value, COD discharge intensity from wastewater treatment and purification facilities, ammonia nitrogen discharge intensity from wastewater treatment and purification facilities, benzene discharge intensity from wastewater treatment and purification facilities, and toluene discharge intensity from wastewater treatment and purification facilities. d) Material cycle indicators refer to the reuse rate of recycled water (medium water). e) Environmental management indicators include the cost of recycled water per ton, the compliance with discharge standards of key pollutant sources, and the audit rate of cleaner production implementation in key enterprises. 4.2 Second-level Indicators 4.2.1 Centralized Wastewater Treatment
