“…Meanwhile, comprehensive research at home and abroad, with China’s actual situation, the suggestions for controlling water pollution are as follows: (1) comprehensively controlling wastewater discharge, establishing an inter-provincial linkage mechanism in the economically developed coastal provinces where high wastewater discharge is concentrated, making neighboring provinces share the common responsibility of reducing the wastewater and, jointly preventing and controlling the wastewater; in the process of industrial introduction, the central and west provinces should set up strict environmental standards, and restrict the development and introduction of industries with high water consumption and high wastewater discharge. While introducing industries, the supporting facilities and related technologies should be focused on [52,53]; (2) when measuring socio-economic development, provinces should introduce and inform the concept of a green GDP index, associate the performance of water conservation goals with local government performance assessment, and ensure wastewater reduction while the national economy maintains a sound development; further strengthening the scientific and technological support, innovating wastewater processing technology, training of wastewater treatment personnel [54], introducing foreign advanced wastewater treatment and management methods, and improving wastewater treatment technologies; promoting the industrial intensive development, improving the efficiency of resource utilization and promoting wastewater recycling by restricting the water quotas, charging at different levels [53], and establishing water consumption indicators based on ten thousand yuan GDP and other ways; vigorously advocating water reservation, communication and popularization of the knowledge of how to deal with domestic wastewater, enhancing public awareness of water conservation, strengthening the public participation and social supervision, and reducing the wastewater discharge at the source.…”

Based on the increasing pressure on the water environment, this study aims to clarify the overall status of wastewater discharge in China, including the spatio-temporal distribution characteristics of wastewater discharge and its driving factors, so as to provide reference for developing “emission reduction” strategies in China and discuss regional sustainable development and resources environment policies. We utilized the Exploratory Spatial Data Analysis (ESDA) method to analyze the characteristics of the spatio-temporal distribution of the total wastewater discharge among 31 provinces in China from 2002 to 2013. Then, we discussed about the driving factors, affected the wastewater discharge through the Logarithmic Mean Divisia Index (LMDI) method and classified those driving factors. Results indicate that: (1) the total wastewater discharge steadily increased, based on the social economic development, with an average growth rate of 5.3% per year; the domestic wastewater discharge is the main source of total wastewater discharge, and the amount of domestic wastewater discharge is larger than the industrial wastewater discharge. There are many spatial differences of wastewater discharge among provinces via the ESDA method. For example, provinces with high wastewater discharge are mainly the developed coastal provinces such as Jiangsu Province and Guangdong Province. Provinces and their surrounding areas with low wastewater discharge are mainly the undeveloped ones in Northwest China; (2) The dominant factors affecting wastewater discharge are the economy and technological advance; The secondary one is the efficiency of resource utilization, which brings about the unstable effect; population plays a less important role in wastewater discharge. The dominant driving factors affecting wastewater discharge among 31 provinces are divided into three types, including two-factor dominant type, three-factor leading type and four-factor antagonistic type. In addition, the proposals aimed at reducing the wastewater discharge are provided on the basis of these three types.

“…However, in order to improve the efficiency of water resource reuse, a large amount of scientific and technological investment is needed, which is time-consuming and laborious for enterprises. Therefore, in order to prevent the above situation, proper tax credits or subsidies need to be given to industrial enterprises with sound pollution abatement schemes and punitive measures taken for industrial enterprises who poorly perform in pollution prevention [51,52].…”

Excess consumption of water resources and environmental pollution have become major challenges restricting sustainable development in China. In order to prevent the pollution of water resources, policymakers should have reliable emission reduction strategies. This paper aims to contribute new knowledge by analyzing the spatial-temporal characteristics and driving forces of point source emission. The chemical oxygen demand (COD) and ammonia nitrogen (NH4-N) emission variations in 31 provinces and municipalities of mainland China during the years 2004–2017 are analyzed. The results obtained using the logarithmic mean Divisia index (LMDI) method indicate that: (1) the COD and NH4-N emission effects have similar temporal characteristics. Technology improvement and pollutant emission intensity are the main factors inhibiting the incremental COD and NH4-N emission effects, while economic development is the main driving factor of COD and NH4-N emission effects. Population increases play a relatively less important role in COD and NH4-N emission effects. (2) The spatial features of COD and NH4-N emission effects show differences among provinces and municipalities. The reduction of COD emission effects in each province and municipality is obviously better than that of NH4-N emissions. (3) In the eastern, central, and the western regions of China, the total COD emission effect shows a downward trend, while apart from the central region, the NH4-N emission effect appears to be rising in the east and west of China. Therefore, increasing investment into pollution treatment, promoting awareness of water conservation, strengthening technological and financial support from the more developed eastern to the less developed central and western regions, can help to reduce the COD and NH4-N emissions in China.

“…Along with this problem, humankind has to face serious environmental and energy problems due to the energy-intensive lifestyle that has emerged in developed countries over the last century [13][14][15][16][17][18][19][20]. In this regard, sustainable conversion of waste to energy or chemicals is considered a reliable way to solve two problems once: reducing the amounts of non-recyclable and non-reusable waste and producing a significant amount of energy and/or chemicals in order to satisfy increasing demand.…”

Pilot Plant Data Assessment in Anaerobic Digestion of Organic Fraction of Municipal Waste Solids

In this paper, a preliminary study of anaerobic digestion of organic fraction of municipal solid wastes (OFMSW) in presented with the aim to compare the performances of both wet- and dry-type reactors. The treatment of OFMSW via anaerobic digestion (AD) producing biogas is a process that is receiving a growing interest because two different needs can be coupled: the request of sustainable municipal waste treatments and increasing demand renewable energy. This paper aims to offer experimental results comparing batch test and continuous experimental reactors under different conditions of humidity and solid content. Results show that both the investigated configurations may be used for converting OFMSW into a high quality biogas and that the increase of dry matter in the continuous process still allows to achieve significant biogas production rates. A slight reduction of the methane content was observed (less than 5% relative) that can be also related to the change in the level of volatile fatty acids. These results are very promising in supporting the possibility of operating an industrial scale plant with a dry-process without affecting the system performance.
