Chitianhua Paper Industry Company is a bamboo pulp production enterprise with advanced technology and large single series output in the world today. It is one of the first pilot enterprises for circular economy in China. In recent years, Chitianhua Paper Industry Company has invested 200 million yuan to accelerate the technological transformation and upgrading of waste gas and wastewater recycling and utilization, and to protect the beautiful Chishui River with practical actions. The original design of Chitianhua Paper Industry Company had an odor collection and treatment system, but after the industrial transformation of 100000 tons of natural color pulp structure, the original system's processing capacity was insufficient. To this end, Chitianhua Paper Industry Company has invested 30 million yuan in the odor optimization and renovation project, adding five sets of odor treatment systems and significantly improving the processing capacity.

The production of pulp and paper generally consists of processes such as pulping, washing, bleaching, and papermaking. The papermaking industry pulp includes alkaline pulp, chemical mechanical pulp, and mechanical pulp. The occurrence and discharge of pollutants in its wastewater vary greatly depending on the different pulping methods, raw materials, pulp yield, papermaking varieties, and the presence or absence of chemical recovery. However, they generally contain a large amount of suspended solids, BOD, COD, and some toxic substances, and are usually treated using a combination of physicochemical and biological methods. The main odor components are organic gases such as methanol, formic acid, acetic acid, unsaturated fatty acids, etc.
