Reclamation and application of sewage heat energy is a good choice for sustainable development and an effective mean of energy-saving and output-reducing. By analyzing the capacity, temperature and quality of sewage of Guiyang, we obtained the basic conditions for the application of sewage heat energy in Guiyang. The results showed that the sewage of Guiyang was resourceful, and have occurrence of large amount of cold (hot) energy. There was an obvious temperature difference between sewage temperature and atmosphere temperature. Sewage was lightly corrosive. The application conditions of sewage heat energy were suitable. Sewage heat is a clean energy which is easy to recycle. Three factors, including capacity, temperature and quality of sewage, are considered if sewage heat energy was applied. 3 factors of 10 sewage treatment plants and their subsidiary pipe network in Guiyang were monitored and analyzed to verify the application conditions of sewage heat energy in Guiyang. From the perspective of energy-saving and output-reducing, an effective way is explored to develop new energy sources in Guiyang[1,2].

Changes of microbial indices of water quality in the Vistula and Brda rivers as a result of sewage treatment plant operationThis paper reports the results of studies of microbiological changes in the water quality of the Vistula and Brda rivers after the opening of sewage treatment plants in Bydgoszcz. The study involved determining the microbiological parameters of water quality. Based on the results obtained, it was found that the quality of the water in both rivers had improved decidedly after the opening of the plants, although an increased number of individual groups of microorganisms was found at the treated sewage outlet from one of the plants.

Wetlands are systems that promote the sustainability and development of a society. The goal of this research was the implementation of a prototype aquatic garden to assess the quality of water in Cajititlán Lake, using sewage treatment plants with the purpose of removing nutrients, phosphates and nitrates among others parameters. This was made possible by floating structures containing aquatic vegetation species like.: Typha latifolia, Lemna minor, Canna indica, Iris pseudacorus, Equisetum arvense, etc. whose basic function is to retain nutrients through phytoremediation processes. The results indicate that the implementation of community wetlands made possible to reduce BOD levels from 220 mg/lt to 12 mg/lt across a surface of 120 m², treating a flow rate of approximately 5.30 gal/min to obtain an effluent in accordance with norm NMX-AA-012-SCFI. It is concluded that community wetlands are suitable ecological alternatives for the treatment of the wastewater discharged directly into the lake.

Global Energy Consumption

According to United Nations data, half of the world’s population lives in cities and forecasts indicate that by the middle of the 21st century, this percentage will have increased to 65%. The increase in the urban population favors the creation of a network of interactions that entails a series of material and energy flows. These cause environmental impacts that affect the quality of life of citizens and the environment as a whole. According to data from the International Energy Agency, cities occupy 3% of the planet’s surface and are responsible for 67% of global energy consumption. The effects caused by this consumption, as well as its impact on the depletion of resources, make it necessary to carry out an exhaustive study of renewable energies and new energy saving systems. This Special Issue aims to present new advances and developments in renewable energy and energy saving systems that allow cities to evolve in a sustainable way.

Risk management, an aspect of which is risk assessment, is a process supporting the proper function of municipal sewage treatment plants. Many factors affect the quality of treated wastewater. Risk assessment, its analysis, and hierarchization permit the elimination of events with the most destructive impacts on the purification process.

The article deals with theoretical and practical aspects of biological waste water rehabilitation of sugar factories by algocoenosis correction. This technology allows you to transfer domestic sewage treatment plant of filtration mode fields in the biological treatment ponds mode, significantly reducing the area of sewage treatment plants, thus improving the quality of treated waste water, which will, in turn, use them repeatedly reducing total water consumption.

Ecotoxicological Assays

Purpose The São Lourenço River (SLR) is used to supply potable waters for the cities of São Lourenço da Serra and Juquitiba, but receives the residues from the water treatment plants (WTPs) and sewage treatment plants (STPs), respectively. The purpose of this paper is to evaluate the impacts of the discharges of Juquitiba’s WTP and STP on the quality of the SLR, by using an integrated approach based on different lines of evidence. Design/methodology/approach Six sampling sites were established along the river and comprised areas situated upstream and downstream of the discharges. Five sampling surveys were performed between 2004 and 2006 for collecting water and sediment samples for ecotoxicological assays. In two of these campaigns, benthic community structure and geochemistry (metals, nutrients and sediment texture) were also assessed. Findings Concentrations of P, Fe and Al in waters exceeded the national standards, but sediments were not considered to be contaminated by metals or nutrients. Water and sediments tended to exhibit marginal toxicities, excluding the sediments from JQT007 and JQT008 that were frequently toxic. Combination of geochemistry, toxicity and ecological indices indicated that some sites are not degraded, but in some stations the benthic alteration may be due to non-measured contaminants, especially in JQT007 and JQT008. Practical implications As the use of waters from SLR for public supply has increased, these results show that action should be taken in order to reverse the environmental degradation of SRL. Originality/value This research combined sediment and water quality assessments in order to provide a more suitable and reliable diagnostic of the environmental quality of the SLR.
