The article contains the approaches of improving the reliability and environmental safety of cleaning waste water treatment plants in the industrial environment, with the help of the express - control methods (oxidation - reduction potential respirometry) and modern technology (biologics, intraband circulation biomass)
Keywords: safety, environmental safety, sewage treatment, waste water, oxidation - reduction potential, respirometry, biologics, intraband circulation biomass
In conditions of reduction of the costs of wastewater actual value of the minimum speed and current case does not provide the required conditions of self-purification of networks. The studies conducted on the silt areas of current collectors of various diameters made of various materials with the purpose of determining the resistance of precipitation in the trays pipes.
Describes the methodology and instruments of research. The data obtained allowed with sufficient certainty have established roughness coefficient bottom sediments of sewers.
Keywords: drainage network, the rate of self-purification, sewer, roughness, bottom sediments.
Article is devoted studying of design parameters water jet aerator. Water jet aerator it is used for saturation of water by oxygen on purification works. In article research methods are described, in particular, possibility of use of computer modeling by means of program complex ANSYS 11 is considered.
Keywords: Water jet aerator, purification works, computer modeling, and jet aeration.
