The environmental risks associated with paper mills grow as demand for paper rises. Wastewater technology for paper mills needs to change due to the expected stricter water treatment regulations. This essay will discuss a combination of aerobic and anaerobic biological treatment and examine how technology advancement has improved the environment. This paper analyzes the new technology and concludes that new strains of bacteria can be introduced to break down the organic matter in the primary settling tank. What’s more, a bubble generator was introduced in the SBR tank to increase the reaction contact area. And the adoption of ozone ceramic membrane bonding technology in the realization of solid-liquid separation in a secondary sedimentation tank. Meanwhile, the combined anaerobic and aerobic treatment process has low operating cost, low residual sludge, modifies the hard-to-degrade organic matter and improves the biochemical properties of the wastewater. Considering the impact on the environment, this paper proposes collecting gas for recycling, establishing tertiary treatment system and adding Fenton's reagent. By comparing the traditional papermaking process and the new microbial treatment technology, a new improvement scheme is proposed, which can help improve the economic efficiency, save resources and protect the environment, and can meet the dual requirements of social development and environmental protection.
