PHOTOREACTOR AND METHOD AND SYSTEM FOR SANITARY AND DOMESTIC SEWAGE AND BILGE SEWAGE WATER TREATMENT GENERATED ESPECIALLY ON SMALL AND MEDIUM WATERCRAFTS OR DRILLING PLATFORMS

摘要

Photoreactor for sanitary and domestic sewage and bilge sewage water treatment generated especially on small and medium watercrafts or drilling platforms fitted with reaction chamber covered with UV- Vis light permeable layer with internally located photocatalyst is characterized according to the invention in that the photocatalyst is modified titanium dioxide(IV). The dioxide is the product achieved through heating process of titanium hydroxide (IV) blended with non metals and/or nanoparticles of precious metals. The method is characterized according to the invention by making the sewage solution the subject to photocatalytic process in the photoreactor with modified titanium dioxide (IV) as the photocatalyst. The system according to the invention is characterized by comprising of at least two slop tanks (3 a, 3 b), connected in parallel by means of a pump (4) and aeration device (5) with the photoreactor (1). The photocatalyst in the photoreactor is modified titanium dioxide (IV).
