Volumes of fresh and reused water.
The total amount of industrial water refers to the amount of water used for production and living in the factory area of industrial enterprises, which is equal to the sum of the quantity of fresh industrial water and quantity of reused industrial water.
Industrial water refers to the general term for produced water used in industrial production processes and domestic water for factory employees. The main uses of production water are: ①Raw material water, water used directly as a raw material or as an integral part of raw materials. ②Water for product processing. ③Boiler water. ④ Cooling water, etc. Among them, cooling water generally represents 60 to 70% of industrial water. Although industrial water consumption is significant, actual consumptionIt’s not big. In general, water consumption accounts for around 0.5 to 10% of the total water consumption, i.e. more than 90% of the water can still be reused after appropriate treatment.
Residential areas mainly consume electricity, fresh water, natural gas, etc.
Electricity accounting is mainly divided into lighting energy consumption, socket energy consumption, air conditioning and HVAC energy consumption, electrical equipment energy consumption. water supply and drainage, etc. The power consumption of lighting and sockets mainly depends on the area of the building, and there is an indicator of lighting density if air conditioning and heating are separated, the number of air conditioners is estimated based on the number of households in the community and the number of air conditioners. the calculation is based on the energy efficiency rate and the powerThis of water supply and drainage equipment is calculated based on the power of the equipment.
Fresh water is calculated based on the number of inhabitants of the community and the value of the per capita water consumption indicator.
Natural gas is also calculated based on the number of residents in the community and the value of the per capita heat consumption index.
