On the morning of the 11th, Changjiang Daily reporter saw a special “fire hydrant†outside the factory area of ​​Dongfeng Honda Automobile Co., Ltd. Unlike most fire hydrants that use tap water, this fire hydrant is connected to the reclaimed water in the Dongfeng Honda Automobile Factory area.
Dongfeng Honda Automobile Factory Fire Hydrant
Reclaimed water, domestic sewage and industrial waste water reach a certain water quality standard after treatment and can be used within a certain range of non-potable water. In the Dongfeng Honda automobile production plant area, the industrial waste water produced every day becomes deep water through advanced treatment, turning waste into treasure.
According to reports, the factory has a sewage treatment station. Industrial wastewater enters the sewage treatment station and is converted into clear, reclaimed water through sand-sluging, biological treatment, and disinfection. A portion of Zhongshui is recycled through pipelines and recycled into the plant area for greening, road washing, equipment cleaning, and toilet water and other domestic water use. The other part is assigned to the fire hydrant outside the factory area for flushing the road surface in the surrounding area.
Recycling to green water
"In addition, it can also be used for production." The company's responsible person said that the design capacity of the sewage treatment station is 2,400 cubic meters per day and the average daily handling capacity is 2,200 cubic meters. Because of the large output, the company is actively promoting the use of recycled water for production. At present, China Water has completed the use of anti-skid tests on vehicles and other projects.
In fact, the reuse of water is one of Dongfeng Honda's many water-saving measures. In recent years, Dongfeng Honda Motors has invested a lot of money in water conservation for the use of new technologies, new equipment, and new processes, and has achieved remarkable results.
Dongfeng Honda Industrial Recycling Water Equipment
For example, with the increase of industrial recycling water equipment, the factory's daily maximum circulation capacity reaches 600,000 cubic meters, annual indirect cooling water circulation is approximately 60 million cubic meters, and the recycling rate can reach 99%. Today, the unit water consumption of Dongfeng Honda Automobile's overall product has gradually dropped from 4 cubic meters in 2012 to less than 3.5 cubic meters in 2016, reaching the leading level in the industry.
The data shows that in 2016, Dongfeng Honda plans to use 1.82 million cubic meters of water, and actually consume 1.697 million cubic meters of water. The annual water consumption is 123,000 cubic meters.
