“…The results based on the above two methods for Tiaozi sediments reveal that it was slightly polluted by Cu, Ni, Cd, and Zn in some sites, especially, with the pollution of Cu being the most severe. Cu-containing effluents are mainly from electroplating, metallurgical, and machine factories [10]. The production of auto parts, special vehicles, and machinery equipment are leading industries in Siping, so Cu, as well as other metal pollution in Tiaozi River sediments, may be associated with the early emissions of wastewater from these industries.…”

“…However, there have been more concerns regarding the level and ecological risk of persistent toxic substances, such as persistent organic pollutants and heavy metals in the river. Previous studies on the pollution of heavy metals in surface sediments of some tributaries in the lower reaches of the Liao have been investigated, and they indicate that the sediments adjacent to big cities and mining areas were contaminated by heavy metals, and the primary characteristic heavy metals were different in different tributaries [10]. For example, Cd and Pb showed more severe enrichment in Daliao River sediments, while Cd and Zn showed more severe enrichment in sediments in the upper reaches of the Hun River [11,12].…”

The objectives of this study were to investigate the seasonal and spatial variations of heavy metal pollution in the overlying water and surface sediments of the Tiaozi River, a tributary of the Liao River, which is one of the seven major rivers and one of the most heavily-polluted rivers in China. Water and sediment samples were collected over four seasons, analyzed for heavy metals (Pb, Cu, Ni, Mn, Cd, and Zn), and assessed with an integrated water quality index (WQI) and a geoaccumulation index (I geo). Results indicated that the maximum concentrations of all the metals in water and sediments occurred in winter and the minimum in summer. Assessment of the pollution indicated that the water was uncontaminated by heavy metals, but the sediments were slightly contaminated with Cu, Ni, Cd, and Zn. Therefore, the pollution of Cu, Ni, Cd, and Zn in the Tiaozi River Basin should be taken into account during the formation of regional management strategies for the water environment.

“…Wan et al (2015) and Song et al (2015a) used membrane technologies for copper removal from aqueous solutions and amantadine by liquid-liquid extractions, respectively. Some technologies allowed for recovery of chemical from wastewater (Liu et al 2015a). Related previous works on MBR are dealing with emerging contaminants from landfill leachates and their sustainable management (Ramakrishnan et al 2015) and the removal of di-/pentachlorophenol from aqueous media by electrochemical process (Huang et al 2013).…”

“…This seems an attractive practice for efficient waste treatment. Different aspects sludge treatment, such as reactivation and succession of microbial communities and fermentation, were investigated byPeng et al (2015a) andLiu et al (2015a), respectively. Nitrogen removal from waste water is an important issue for water quality improvement in China(Gao et al 2015a) and other countries (AlDwairi et al 2014;Cicchella et al 2014;Pascual Aguilar et al 2014).…”

Rapid economic development and population growth in China go hand-in-hand with increasing urbanisation, involving growing mega-cities, industrialization, and intensified agriculture. As a result, natural resources are increasingly stressed and productive management strategies towards sustainable planning are urgently needed. Pollution containing hazardous substances for environmental and human health, depletion of water resources as a result of overexploitation, soil degradation and air pollution in mega-cities (such as Beijing or Shanghai) are increasing at an alarming rate. Consequently, the protection of aquatic ecosystems and the security of drinking water provision are becoming an increasing challenge in water management. The Chinese government recognized the importance and complexity of the situation and has initiated a program entitled ''Major Program of Science and Technology for Water Pollution and Governance'' (2006-2020) (Major Water Program). While shortages resulting from regional resource depletion have led to plans for large-scale water transport from distant water-rich areas of China (Water Diversion Project), the water quality problems in other areas require efficient, flexible, and site-specific solutions and overall management concepts. China is internationally cooperating with many countries to tackle the severe environmental problems and learning from their experiences. In particular, China can benefit from the lessons learnt in Germany concerning the rehabilitation of water resources in areas heavily affected by chemical industry and mining after the reunification in 1989. German-Chinese cooperation in water sciences started over 25 years ago and is dealing now with increasing challenges in the 21st century (Chen et al. 2015). Under the umbrella of ''International Partnerships for Sustainable Technologies and Services for Climate Protection and the Environment'' (CLIENT) under the ''Research for Sustainable Development'' framework programme the Federal Ministry of Education and Research of Germany (BMBF) started a series of research projects supporting the Chinese Major Water Program in several regions, the lakes, Taihu, Chaohu and Dianchi, as well as the Liao River Basin (Fig. 1). The Liao River Basin is located in northeast China with two river systems, one system is the Liao River formed by converging Xiliao River and Dongliao River, and the other system is the Daliao River formed by converging Hun River and Taizi River (Fig. 1). The province of Liaoning derived its name from the river. Shenyang is the provincial capital of Liaoning. Liaoning was one of the first provinces in China to industrialize and heavy industry led to severe environmental pollution including the water environment. Liaoning has the largest economy of Northeast China covering a wide range of industries, such as metallurgy, petroleum, chemical industries, pulp and paper making, pharmaceutical industry, printing and dyeing, machinery, electronics, metal refining, construction materials, ore and coal mining, etc. The Lia...
