“…− ) is an increasingly serious pollutant in agricultural, urban, and industrial wastewater [1,2] due to the excessive use of fertilizers, discharge of livestock wastewater, and the infiltration of landfill leachate [3]. Previous reports demonstrated that nitrate could be removed efficiently and at a low-cost by microorganisms through assimilatory and dissimilatory reactions [4,5].…”

The negative effect of ZnO nanoparticles (ZnO-NPs) on the biological removal of nitrate (NO3−) has received extensive attention, but the underlying mechanism is controversial. Additionally, there is no research on Fe2+ used to alleviate the cytotoxicity of NPs. In this paper, the effects of different doses of ZnO-NPs on the growth and NO3− removal of Pseudomonas tolaasii Y-11 were studied with or without Fe2+. The results showed that ZnO-NPs had a dose-dependent inhibition on the growth and NO3− removal of Pseudomonas tolaasii Y-11 and achieved cytotoxic effects through both the NPs themselves and the released Zn2+. The addition of Fe2+ changed the behavior of ZnO-NPs in an aqueous solution (inhibiting the release of toxic Zn2+ and promoting the aggregation of ZnO-NPs), thereby alleviating the poisonous effect of ZnO-NPs on the growth and nitrogen removal of P. tolaasii Y-11. This study provides a theoretical method for exploring the mitigation of the acute toxicity of ZnO-NPs to denitrifying microorganisms.

“…Zhu et al [43] conducted a case study on how firms in development zones responded to increasingly demanding environmental regulations. Hu et al [44] explored the development of centralized wastewater treatment plants in Chinese national industrial parks and pointed out that 92% of treatment plants met the required discharge standards. Long et al [45] analyzed pollution control and the cost of wastewater treatment at Taihu and Haihe industrial parks.…”

This paper investigates the relationship between agglomeration and water pollution, and the effect of environment policies on water pollution reduction. The study employs a quasi-natural experimental method by coupling river water monitoring sites and development zones (DZs). We found that DZs were associated with water quality deterioration in their surrounding areas. However, the “Water Ten Plan”, which was released in 2015 and requires DZs to install water treatment facilities, effectively reduced water pollution, especially for those DZs with more polluting industries. Our findings provide evidence that agglomeration can facilitate efficient processing of wastewater by enabling its centralized treatment. The paper provides quantitative evidence for the effect of agglomeration and environmental policies from a micro point of view.

“…Thus, the appropriate control of wastewater treatment plants (WWTPs) in individual manufacturers and of the centralized WWTPs in parks can reduce organic pollutants, nutrients, and heavy metal pollutants (Chen et al., 2017; Lyu et al., 2020). The two‐stage wastewater treatment system, that is, an in‐plant WWTP followed by a centralized wastewater treatment plant (CWWTP), has been widely employed in Chinese IPs (Hu et al., 2019). Individual enterprises are requested to treat wastewater in their own WWTPs satisfying specific emission limits and then discharge the treated wastewater into the CWWTPs in parks for further treatment.…”

As the most important production space for the development of chemical industry in China, chemical industrial parks (CIPs) are facing a new challenge of water pollution prevention and control, in addition to those posed by traditional and emerging pollutants. It is thus important to systematically reveal the compositewater‐environmental impact of CIPs for contributing to the sustainable development of the chemical industry. CIPs have the issue of intensive wastewater generation characterized by complex pollutant components and high pollution loads. Thus, establishing an environmentally friendly wastewater treatment system has always been a major challenge for CIPs. China has developed many CIPs and the two‐stage wastewater treatment system is widely employed in practice, that is, in‐plant wastewater treatment plants (WWTPs) in individual enterprises followed by centralized WWTPs in parks. Since the CIP wastewater emission limits are continuously improved, a comprehensive evaluation of the environmental impacts of the in‐use wastewater treatment system will be insightful for future policy making. This study employed life cycle assessment (LCA) to reveal the life cycle environmental impact of the two‐stage wastewater treatment system in a typical CIP. We found that the life cycle environmental impacts of the whole system mainly stem from the in‐plant WWTPs of chemical manufacturers because of chemicals and electricity consumed in the multi‐stage advanced oxidation technologies, while the increase of human toxicity potential and marine aquatic ecotoxicity potential are primarily due to sludge incineration. Three scenarios targeting the reduction of environmental impacts were proposed based on the LCA results. We evaluated the pollution mitigation potential, which can reach at most 8% of the original measured impacts. Finally, from the perspective of systematic thinking, four policy implications for improving the water management system of CIPs were proposed.
