HG/T 6237-2023 in English

The "Technical Specifications for the Treatment and Reuse of Organic Nitrogen Industrial Wastewater" (Standard Number: HG/T 6237-2023) is a crucial guideline in the chemical industry, designed to address the environmental challenges posed by organic nitrogen wastewater. This standard was released on December 20, 2023 and will come into effect from July 1, 2024.

The objective of this technical specification is to provide detailed guidelines for managing and treating industrial wastewater containing organic nitrogen compounds. It aims at promoting sustainable practices by ensuring that the treated water can be reused within industrial processes or safely discharged without causing environmental harm.

This document covers various aspects such as pretreatment requirements, primary treatment techniques like biological nitrification-denitrification, advanced oxidation processes for degradation of refractory organics, and membrane filtration technologies. Additionally, it emphasizes on monitoring parameters, operational guidelines for effective wastewater management systems, and considerations for the selection of appropriate treatment methods based on the characteristics of organic nitrogen compounds.

The implementation of HG/T 6237-2023 will contribute significantly to enhancing environmental protection standards in the chemical industry while supporting the sustainability goals by promoting circular economy principles through water reuse.
