4 Calculation methods

1 Calculation range 4:1:

1 The calculation scope of water sources includes surface water (measured by water supply from water purification plants), groundwater, urban water supply projects, and enterprises' supply from the market: Purchased other water or water products (such as steam, hot water, geothermal water, etc:): 4:1:

2 The calculation scope of water intake includes main production systems (primary processing of raw materials, strip making, dyeing, spinning, weaving and finishing, etc:), auxiliary Production systems (soft water stations, boiler rooms, air compressor stations, sewage stations, air conditioning units, etc:) and ancillary production systems (office buildings, canteens, bathrooms, factory dormitories, etc:) housing, greening, etc:): 4:

2 Calculation formula The water intake per unit product is calculated according to formula (1): Vui= Vi (1) In the formula: Vui

---water intake per unit product, the unit is cubic meters per hundred meters (m3/100m) or cubic meters per ton (m3/t); Vi

--- During the statistical reporting period, the total amount of water taken by an enterprise to produce a certain wool textile product, in cubic meters (m3); Q

--- During the statistical reporting period, the company's production of certain wool textile qualified products is equivalent to the standard product output: According to different product types, the measurement sheet Bits are measured in hundreds of meters (100m) or tons (t):
