Industrial wastewater projects require more to determine the test items are more complex, according to different processes and the implementation of the emission standards to determine the detection of the project. Industrial wastewater discharge standards are developed by industry, commonly used industrial wastewater discharge standards are:

■ 《造紙工業(yè)水污染物排放標(biāo)準(zhǔn)（GB3544-2008）》 

■ 《鋼鐵工業(yè)水污染物排放標(biāo)準(zhǔn)（GB13456-92）》 

■ 《紡織染整工業(yè)水污染物排放標(biāo)準(zhǔn)（GB4287-92）》
