Analysis of acid wastewater by GC-MS
Research of acid mine wastewater treatment technology
Research of acid mine wastewater treatment technology

In many countries and areas, acid mine drainage leads to serious environmental pollution. The article analyses the source and mechanism of the acidic mining waste water. Some commonly used treatment technologies and principle of mine acid waste water treatment were analyzed. And the characteristics of several treatment methods are

pollutants in the wastewater. Acetic acid is present in the effluent from petroleum, fine chemical, pharmaceutical and textile industry. In this review, the research carried out to remove acetic acid and the results are summarized with respect to the methods used and the effectiveness of the method.

Here we have reviewed ,pollutants, from various industries and examined how ,wastewater, can be treated and reused. It is necessary to first know the ,wastewater, components so that suitable technologies can be developed for water treatment before it is released back into water bodies or recycled for irrigation, landscaping, etc.

Being strongly hydrophobic these organic ,pollutants, are efficiently removed during urban ,wastewater, treatment (WWTS) and bind to the sludge solids. However, the increasing body of scientific evidence has not identified a potential harmful impact of these substances on the environment in the context of the urban ,wastewater, system.

wastewater, as a dioxin source has been underestimated [Horstmann et.al., 1993, Horstmann, 1995]. Sources of other potential ,organic pollutants, are listed below: ,Organic pollutants, can originate from food and household related products, such as long chain fatty acids and their methyl and ethyl esters, originating from faeces, soaps and food oils.

Acetic acid is one of organic pollutants found in wastewater produced from domestic households, industrial and agricultural practices, etc. However, HPLC with UV detection was not used for trace acetic acid due to the limited sensitivity for its low wavelength (λmax = 205 nm) and weak absorption.

The aim of this research was to determine the effect of formic ,acid, on pollutant decompo-sition in textile ,wastewater, subjected to treatment by the Fenton method. To estimate the effect of formic ,acid, on treatment efficiency for different types of textile ,wastewater, tested, COD reduction in mixtures of ,wastewater, and formic ,acid, was calculated.

Wastewater can contain physical, chemical and biological pollutants. Households may produce wastewater from flush toilets, sinks, dishwashers, washing machines, bath tubs, and showers. Households that use dry toilets produce less wastewater than those that use flush toilets. Wastewater may be conveyed in a sanitary sewer that conveys only sewage.

Viruses are among the most important and potentially most hazardous pollutants in wastewater. They are more resistant to treatment, more infectious, more difficult to detect and require smaller doses to cause infections (Okoh et al., 2007). For bacteria, they are the most common microbial pollutants in …
