One of the pressing issues of improving the geo-ecological environment is creating new and effective technological solutions cheap wastewater treatment. At full biological treatment of waste water can not be removed until the required standards are harmful and widespread pollution, synthetic surfactants, oil, nitrogen and phosphorus compounds, heavy metal salts and other solutes. Such structures are made of reinforced concrete structures, requires a supply of electricity, have high construction and maintenance cost as well as the need constant maintenance. Therefore, for deep cleaning of wastewater must be a combination of biological treatment technology with physical and chemical methods. They combine the efficiency of a large, low cost and high environmental, construction and operation. To this end, developed chemical and biological wastewater treatment technology using raw materials more accessible local origin for the climate of Uzbekistan (Fig.1).
