TREATMENT METHOD FOR ORGANIC WASTEWATER AND USE OF SAME

WIPO Patent Application WO/2018/199330

A1

The purpose of the present invention is to provide a treatment method by which, even for wastewater with organic constituents constituting a large portion of organic wastewater as a whole and suspended solids (SS) and with a large negative charge ratio, organic nitrogen constituents and phosphorus compounds can be efficiently separated and collected and good-quality separated water can be obtained by reducing the quantity of SS, BOD, COD, and nitrogen constituents in the separated water. Provided is a treatment method for organic waste water, in which a flock is formed by adding a polymer flocculant to organic waste water with organic nitrogen constituent content in relation to suspended solids (SS) being 4–50%/SS and organic nitrogen constituent content being 250–50,000 mg/L, and thereafter, the flock is separated from the organic wastewater by solid–liquid separation.
