2.3.1. Technologies of treating industrial and surface waste waters from power companies

  • 2.3.1.1. General data on technologies of treating waste water from power companies

    Ksenofontov B.S., MSTU of Bauman

    A choice of the method depends on a variety of factors, in particular, requirements to the cleared waste water quality, location of the enterprise and availability of necessary power and material resources needed for waste water treatment, etc.

  • 2.3.1.2. Mechanical waste water treatment

    Ksenofontov B.S., MSTU of Bauman

    In waste water mechanical treatment units the largest impurities are firstly separated on lattices and sieves, installed in the lead of the treatment unit, then suspended particles with a size, as a rule, of more than 0,15 … 0,2 mm are falling out from waste water in sand separators.

  • 2.3.1.3. Chemical waste water treatment

    Ksenofontov B.S., MSTU of Bauman

     Neutralization, oxidation and deoxidation are commonly referred to chemical waste water treatment methods. These methods are applied for removal of the dissolved substances both before giving on biological clearing, and in the closed cycles of water use.

  • 2.3.1.4. Physical and chemical waste water treatment

    Ksenofontov B.S., MSTU of Bauman

     Physical and chemical water treatment methods usually include coagulation, flocculation, flotation, adsorption, extraction, an ionic exchange, ultrafiltration, reverse osmosis, evaporation, etc. Coagulation and flocculation of waste water proceed similar to natural water treatment for household purposes.

  • 2.3.1.5. Biological waste water treatment

    Ksenofontov B.S., MSTU of Bauman

     Biological treatment is the most widespread technology of waste water treatment known for more than 100 years. Contemporary ways of biological treatment incorporate substantially all known metabolic features of microorganisms.

  • 2.3.1.6. Waste water polishing at activated coal

    Ksenofontov B.S., MSTU of Bauman

     The term “polishing” refers to methods and processes supplementing common treatment of water of a given composition. Due to wide spread of bio-chemical treatment (BCT) of general waste water flow mechanical treatment is considered to be a primary treatment, biological-secondary, polishing tertiary. There at polishing yields achievement of any required and achievable degree of pollution removal or destruction. Sorption at activated coals allows additional extraction from water after BCT of more than 80 % of remained impurities.
