Problems solved by technology

Both ways contribute to further mineralization and significantly increase the cost
This approach has not actually been used in practice because of the very high cost of such modification, the higher sensitivity of organisms to altered environmental conditions and the need to significantly increase the amount of oxygen used

Abstract

The invention relates to a method for biological treatment of water, wherein macromolecular carbohydrates are added to the water to be treated, optionally together with vitamins and other additives, whereby a great reduction in residues is already achieved after adding small amounts of macromolecular carbohydrates, for example 0.4 to 600 mg / kg BSB5,zw or 0.014 to 14 mg / kg dry activated sludge daily.

Description

technical field [0001] The invention relates to a method for biological treatment of water and a water treatment agent, which is metered into a device for biological treatment of water to achieve the purpose of reducing the amount of generated residual substances. Background technique [0002] Biological methods are used not only for the treatment of domestic water but also for the treatment of industrial water. During bioconversion of dissolved and undissolved contents, newly formed microorganisms are separated from the biorefractory solid matter contained in the water and subsequently removed from the treatment unit. This residue is used in agriculture or in re-cultivation depending on the harmful substances contained and their concentration. In addition, heat treatment and storage as well as utilization / disposal by special methods are practical. Agricultural utilization can be carried out directly or after pretreatment. Most cleanup / utilization options require pre-trea...
