The Faminin area in the semi-arid Hamadan state, western Iran is facing a serious deficiency in groundwater resources due
to an increasing demand associated with rapid population growth and agricultural development. The chemical composition of
78 well samples throughout the Faminin area was determined with the aim of evaluating the concentration of the background
ions and identifying the major hydrogeochemical processes that control the groundwater chemistry. The similarity between rock
and groundwater chemistries in the recharge area indicates a significant rock-water interaction. The hydrochemical types Na–HCO3 and Na–SO4 are the predominate forms in the groundwater, followed by water types Ca–HCO3 and Na–Cl. The high values of electrical conductivity and high concentrations of Na+, Cl−, SO42− and NO3− in the groundwater appeared to be caused by the dissolution of mineral phases and would appeared to be caused by anthropogenic
activities, such as intense agricultural practices (application of fertilizers, irrigation practice), urban and industrial
waste discharge, among others. 相似文献

The rising occurrence of emerging contaminants in sludges both inhibits the anaerobic digestion of sludges and induces health issues when sludges are recycled in agriculture, calling for methods to remove contaminants. Here we review emerging pollutants in wastewater treatment plants, before and after anaerobic digestion. We present their inhibitory effects and remediation methods to alleviate inhibition. Pharmaceuticals have been detected in about 50% of the sludge samples. Sewage sludge contaminants include 19% of diuretics, 16–21% of lipid-modifying agents, hydrochlorothiazide, diclofenac, furosemide, clarithromycin, atorvastatin, and carbamazepine. Levels of antibiotics, azithromycin, ciprofloxacin, and estrone range from 500 to 600 ng/g in sludges from wastewater treatment plants. Remediation methods comprise electrooxidation, ultrasonication, thermal hydrolysis, ozonation, and bioaugmentation. Fermenting the sludges with acidogenic bacteria reduces the level of emerging pollutants in the supernatant. Nonetheless, liquid digestates still contains emerging pollutants such as sunscreen octocrylene at 147 ug/L and acetaminophen at 58.6 ug/L. As a result, pretreatment of sludge containing emerging pollutants is required.
