The invention relates to modular process with changeable and continuous flow modular system for the treatment of water streams, namely to the process for removal of organic and inorganic substances with the help of combination of biological and physical-chemical processes. The modular process is declared for the treatment of water streams with changeable and continuous flow, in which aerobic biological process of water stream, which is polluted, is carried out, with aeration and oxidation of water stream, the process is provided with one or more aeration stations for recovery of level of oxygen, solved in water, that allows aerobic biological process, using bacteria and oxidation capacity of aeration to consume organic substances, particularly substances, solved in water without addition of mixture of chemicals with water stream (CA), with formation of initial stream (E1) and further treatment with physical-chemical process (2), comprising stages of addition of flocculation or coagulating agents, gathering of suspended particles with formation of flocks of large size and density, determining flocculation basin (F1) below the water stream, after that a set of particles of large size and density is given at least to one microaeration stage (M1) with microbubbles along the water stream (CA), determining flocculation basin (Fo1) in such a way that agglomeration, concentration and sealing of floated materials, and also providing of removal (R) of concentrated floated material are carried out, and the mentioned physical-chemical process (2) is carried out along the water stream, and after that aerobic biological process (3) is carried out with aeration and oxidation of water stream (CA), which is equipped with one or more intermediate aeration stations (A1-3), (A2-3), (An-3), fixed along the treatment, as a result of which the initial stream (E3) is formed, which is given to treatment with the help of physical-chemical process (4), which removes residua after physical-chemical treatment (2) and solid particles, formed at treatment, comprising aerobic biological process (3) with aeration and oxidation of water stream (CA). |
