NOTE: commercialized products are mainly laundry soaps (including transparent laundry soaps) and toilet soaps. 3.2 Powder or Other Solid Detergents Powder or other solid detergents refer to powdered, striped, blocky, flaky or other solid detergent products that are combined by surfactants and some organic or / and inorganic additives in a certain formula ratio. NOTE: including laundry soap powder compounded with surfactants and soap ingredients. 3.3 Liquid Detergent Liquid detergent refers to liquid detergent product mixed by water, surfactants and a small amount of organic or / and inorganic additives in a certain formula ratio.4 Assessment Requirements4.1 Product Classification In accordance with product processing technology, detergent products are divided into soaps, powder or other solid detergents and liquid detergents. 4.2 Basic Requirements 4.2.1 The pollutant discharge condition of the product manufacturer shall comply withAppendix A(normative) Sampling Monitoring Method, Index Calculation Method and Inspection Method A.1 Sampling Monitoring Method The sampling of the various indexes involved in this Standard shall be executed in accordance with the standard monitoring methods specified by the state. The wastewater pollutant production index refers to the index before the end treatment, which shall be accumulated after the monitoring or installation in each workshop. All indexes are averaged in accordance with the actually measured data of the sampling times. The enterprise’s raw materials, freshwater intake and energy consumption, product output and process energy consumption are all subject to monthly or annual reports. A.2 Calculation Method and Inspection Method A.2.1 Alkali consumption per unit (calculated as 100% NaOH) During the soap production process, the consumption of alkali (calculated as 100% NaOH) used in the production of 1 ton of soaps (converted into 72% fatty acid) shall be calculated in accordance with Formula (A.1): Where, Mgd---the consumption of alkali (calculated as 100% NaOH) used in the production of each ton of soaps, expressed in (kg/t); Mgx---within a certain measurement time (usually one year), the consumption of alkali (calculated as 100% NaOH), expressed in (kg); Mc---within the same measurement time (usually one year), the output of soaps, expressed in (t). A.2.2 Grease consumption per unit During the soap production process, the consumption of grease (commonly known as “absolute oil”) used in the production of 1 ton of soaps (converted into 72% fatty acid) shall be calculated in accordance with the same method as A.2.1. A.2.3 Fatty acid utilization rate Where, E---comprehensive energy consumption per unit (calculated as standard coal), expressed in (kg/t); ei---within a certain measurement time (usually one year), the actual amount of the ith energy consumed in production and service activities, expressed in (kg); pi---the conversion coefficient of the ith energy, converted in accordance with the equivalent value of the energy; Mc---within the same measurement time (usually one year), the output of detergents, expressed in (t); n---the number of energies. NOTE: comprehensive energy consumption mainly includes primary energy (such as: coal, petroleum and natural gas, etc.), secondary energy (such as: steam and electricity, etc.) and energy-consuming working medium directly used for production (such as: cooling water and compressed air, etc.), but does not include energy-consuming working medium used for power consumption (such as: power generation and boiler, etc.). A.2.6 Wastewater discharge per unit The amount of wastewater generated during the production of 1 ton of detergents shall be calculated in accordance with Formula (A.5): Where, Vc---the amount of wastewater generated by the production of each ton of detergents, expressed in (m3/t); Vj---within a certain measurement time (usually one year), the average value of enterprise’s wastewater discharge in the jth production link, expressed in (m3); Mc---within the same measurement time (usually one year), the output of detergents, expressed in (t); n---the number of detergent production links, expressed in link (s). ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
