Iron-arsenic coprecipitate is a kind of solid waste produced in the treatment of arsenic-bearing wastewater from non-ferrous metallurgy. Stability of amorphous coprecipitates is usually poor if the Fe/As ratio is lower. In this study, the surface of coprecipitates was deposited with aluminum hydroxide with the aim to prevent the release of arsenic....

The anaerobic fermentation of water hyacinth is an effective way to turn waste-water hyacinth (a noxious plant of malignant growth) into treasure (methane). However, the technology also brings much water hyacinth anaerobic fermentation wastewater with high COD value, high ammonia nitrogen value and deep color, and thus specific treatment of wastewa...

Effective recycling waste lithium-ion batteries (LIBs) are of great economic and environmental benefits. This study proposes a novel and efficient ammonia leaching method for recovering Co and Li from waste LIBs. This method yields a Co and Li leaching rate of 91.16% and 97.57%, respectively, under the optimal conditions (NH3 center dot H2O 120 g/L...

A series of nanocrystalline copper-manganese oxides (denoted as Cu3-xMnx, x = 0, 1, 1.5, 2, 2.5, 3, where x means the molar ratio of Cu and Mn) were successfully prepared by a facile citric acid sol-gel method. The combination of Cu2+ and Mn3+ is intensified and enhanced interface effects generated, which is beneficial for the catalytic oxidation o...

Arsenic-containing acid wastewater produced in the mining and smelting process will bring great harm to the environment, while to treat arsenic-containing wastewater with iron salt and lime is an economical and effective method. In this paper, iron salt was added to co-precipitate the arsenic and heavy metals, the pH value of arsenic containing aci...

Wastewater treatment is one important issue for turpentine plant and more wastewater generated by greater turpentine processing will prevent its further development. To solve this issue without extra place and new equipment, one industrial system for reuse and treatment of turpentine processing wastewater was introduced for the first time. For wast...
