What printing and dyeing factories are there in Nantong (including other affiliated counties and cities such as Hai 'an and Haimen)? There are a lot of wastewater produced by the factories. Thank you ~ There are several in Haimen, one in Tianbu, one in Linjiang and one in Qinglong Port. There are many in Tongzhou, near the Samsung area of Jiangzao, Zhihao and Haimen, where there are many textile enterprises, and many printing and dyeing facilities. There are also many such lengths in southern Jiangsu. There is also one in Zhuhang, Tongzhou, near the Yangtze River.
