< p > "last year when the enterprise moved to build a new factory, the water consumption per ton of cloth decreased from 180 tons to 100 tons, and the steam consumption also decreased by half. Nearly 50% of the waste water could be reused." Xiaogang dyeing and printing factory director Wu Jingguo said. It is understood that 20 printing and dyeing enterprises in Beilun district have recently completed renovation and upgrading. Compared with pre regulation, last year, the gross domestic product increased by 12% over the same period last year, and the emissions of waste water, COD and ammonia nitrogen decreased by 2%, 7.4% and 11% compared with the same period last year. < /p >
< p > > a href= "http:// m.pmae.cn/news/index_c.asp" > Xiaogang dyeing and printing plant < /a > is a sole proprietorship enterprise established in the early 80s of last century. Last year, enterprises moved to industrial zones with more perfect facilities such as heating, sewage and other facilities, invested 40 million yuan to build new factories and purchased reclaimed water reuse equipment. Not only did they discharge more than half of the sewage, but also the quality of products improved rapidly. < /p >
< p > it is understood that many printing and dyeing enterprises in Beilun district have been established for a long time, with high energy consumption, low energy consumption, < a href= "http:// m.pmae.cn/news/index_c.asp" > equipment aging < /a > and so on. Some enterprises have low level of clean production and insufficient capacity of reclaimed water, and some enterprises do not have facilities for purifying waste gas, resulting in direct emission of exhaust gas, which has a great impact on the surrounding environment. < /p >
< p > from 2012 onward, Beilun district began to carry out rectification and upgrading work for < a href= "http:// m.pmae.cn/news/index_c.asp" > printing and dyeing industry < /a >. According to the principle of one enterprise and one policy, the 4 enterprises of Zhedong Xing Yang blankets and Vico Dunhuang knitwear were eliminated in situ, Xiaogang dyeing and printing plant was rebuilt into the park, and the remaining 15 enterprises such as Shenzhou knitting company were initially completed and upgraded to enhance their work. < /p >
< p > in recent years, the textile industry is not very prosperous, but the input of enterprises in upgrading is not unambiguous. < /p >
< p > "last year, the enterprise only had a profit of about two million yuan, but we invested nearly ten million yuan to upgrade the pollution control facilities, such as the new reverse osmosis water reuse device with 600 tons of daily sewage treatment. Responsible person of Ningbo Zhi Da Textile Co., Ltd. said that doing environmental protection work well is the social responsibility of enterprises, and we are willing to invest. < /p >
