Special Issue Information

Dear Colleagues,

Recently, rural wastewater has come to pose a series great threats to environmental pollution and aquatic ecological safety. The discharges of rural sewage, animal breeding wastewater, and aquaculture tailwater, always result in many black and odorous water bodies and serious drinking water shortages, especially in developing regions. Cost-effective treatment technology ensures a wide applicability in rural areas around the world. Resource utilization is also a treatment method from some perspectives, one which can contribute to the cyclic uitilization of water and nutrient in rural wastewater. Villagers’ intention is remarkable resource with which to achieve the sustainable construction and management of rural wastwtaer treatment facilities.  

In this Special Issue, articles summarizing the review, management, and treatment technology of rural water pollution are welcome. Understanding transformation characteristics and on-line monitoring of physical, chemical and biological processes is necessary for the removal of various pollutants from rural wastewater. Novel practices for improving treatment performances of constructed wetlands, bioreactors, membranes, soil purificaiton systems, et al., in addition to exploring  organic solid waste treatment and resource utilization, are encouraged.  In addition, the evalution of decentralized wastewater management modes is interesting and presents a challenge for overcoming the uncertainties with regard to  improving wastewater treatment efficiency in rural areas.

The main aim of this research was to determine the physiological response of the submerged macrophyte Vallisneria natans (V. natans) to black water with a foul odor. V. natans was chosen as the experimental plant species to investigate the morphological response and ecophysiological adaptation methods in response to varying light depths and black-odorous water. V. natans was planted in tap water (D), two types of black-odorous water (E and F), and under three distinct light conditions (low light, medium light, and high light). In the high-light condition with black-odorous water (E), the biomass content of V. natans declined from 1.78 g on the 14th day to 1.49 g on the 28th day, demonstrating that the black-odorous water inhibited the growth of V. natans. Under the stress of black-odorous water, the chlorophyll content of V. natans increased greatly in the early period but reduced during the latter experimental period. However, on the 21st day, maximum chlorophyll content of 1.30 mg/g (E) and 1.18 mg/g (F) was observed. In addition, the malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) activity was monitored and reported under black-odorous water stress in V. natans. The experimental results of this work demonstrated conclusively that odorous black water exerts a certain stress on the physiological development of V. natans. Future research should incorporate the evaluation of several plant species and vary the process and environmental conditions to produce field-relevant, dependable results. Full article
