Laboratory experiments in wastewater treatment plants
In continuation of the series of lectures of the cultural season of the Environment Research Center at the University of Technology-Iraq, in the presence of the Director of the Center, Professor Dr. Abdul Hameed M. Jawad, and in the presence of a group of academics and researchers, Dr. Rana Riyadh Khaleel, a lecture entitled (Laboratory Experiments in Wastewater Treatment Plants), on Tuesday 7/12/2021 at 11 am...
The lecture began by defining the topic. Sanitary sewage water consists of household waste, which includes remnants of fats, foods, and industrial detergents used in washing and cleaning, organic materials and human waste, as well as industrial waste, which is water left by factories and contains different percentages of organic and chemical substances, in addition to the rinsing water for home yards. Carrying dust and some suspended matter. The main dangers that lie in sewage water are pathogenic germs that are transmitted with wastewater and sludge, which can cause many diseases. The most important of these pathogenic germs found in sewage water, including harmful bacteria that cause typhoid, cholera, dysentery, and other diseases Infectious and protozoa, which are widespread in sewage water, and some of them transmit amoebic dysentery, in addition to fungi.
With regard to the environment, there are serious negative effects of sewage that affect human life and society in a direct way, which are the environmental effects resulting from the drainage of sewage water into the sea or river, which leads to distorting the aesthetic aspect of the beaches and the spread of many germs on the coastal areas, which leads to serious health damage to the visitors. These beaches and the marine and natural environment, in addition to the spread of unpleasant odors represented by H2S gas, affect the nervous system and causes eye diseases and allergies.
Due to the scientific progress in many fields and the growing interest in protecting the environment from pollution, restrictions have increased on the disposal of sewage, especially from industrial areas, where disposal does not allow it to be drained into rivers or buried in open lands. Many industries, especially those that produce waste, have increased restrictions. Highly polluted, these wastes should be adequately treated inside factories through special purification plants before being discharged to sewage networks or disposed of in any other way.
