摘要 |
<p>According to the invention, the hardly biodegradable or non-biodegradable constituents are separated and concentrated to give a concentrate, the concentrate is preferably physically and/or chemically treated and the treated or untreated concentrate is subjected to a biological reaction or the concentrate is alternatively separated from the waste water to be purified. An apparatus for carrying out the process contains a membrane filtration device or nanofiltration device (19), to which the waste water having the hardly biodegradable or non-biodegradable constituents (16) to be concentrated is fed on the inlet side and in which the hardly biodegradable or non-biodegradable constituents are retained and from which the purified waste water (24) is discharged on the outlet side, and a filtration reservoir (15) connected to the membrane filtration device or nanofiltration device (19), which reservoir acts for concentration of the hardly biodegradable or non-biodegradable constituents of the waste water.</p> |
