GB 4284-2018Control standards of pollutants in sludge for agricultural use (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB 4284-1984 "Control Standard for Pollutants of Agricultural Sludge". Major technical changes compared to GB 4284-1984 as follows:

--- Revised the scope of application (see Chapter 1);

--- Added normative references (see Chapter 2);

--- Increased the definition of sludge and agricultural sludge from urban sewage treatment plants (see Chapter 3);

--- Increase the limits of polycyclic aromatic hydrocarbons (see 4.1);

--- Increased the types and regulations of agricultural land that allow the use of sludge products (see 4.1);

--- Revised the contaminant concentration limit for sludge products (see 4.1, version

1.1 of the 1984 edition);

--- Increased hygiene requirements (see 4.2);

--- Increased the requirements of physical and chemical indicators (see 4.3);

--- Revised the amount of application per acre per year (see 4.4, 1984 version 2.1);

--- Revised the number of years of continuous use in the same plot (see 4.4, 1984 version 2.1);

--- Increased detection and analysis methods (see Chapter 5);

--- Increased requirements for monitoring and sampling methods (see Chapter 6). This standard is proposed and managed by the Ministry of Housing and Urban-Rural Development of the People's Republic of China. This standard is drafted by: Institute of Geographical Sciences and Natural Resources Research, Chinese Academy of Sciences, Agricultural Resources and Agricultural Region of the Chinese Academy of Agricultural Sciences Institute, National Sludge Treatment and Disposal Promotion Association, China National Institute of Standardization, China Academy of Environmental Sciences.

1 Scope

GB 4284-2018 is the Chinese national standard on control standards of pollutants in sludge for agricultural use, in the field of civil engineering. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 14 May 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 June 2019. Classification: ICS 93.030, CCS P41. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the pollutant control indicators, sampling, detection, monitoring and sampling methods for sludge treatment in urban sewage treatment plants. This standard applies to the control of pollutants in urban sewage treatment plant sludge in cultivated land, garden land and pasture.
