High-molecular sewage low-temperature separation device

Abstract

The invention relates to sewage treatment equipment, and particularly relates to a high-molecular sewage low-temperature separation device which realizes separation through temperature control by utilizing the physical boiling point characteristic of a high-molecular compound. The device comprises a heating mechanism, a tank body and a tank cover; the heating mechanism is positioned at the bottomof the tank body; the tank cover comprises a collecting part and a recycling part; the recycling part is an annular depression; and the recycling part is arranged at the edge of the collecting part. The temperature of the heating mechanism is controlled to a certain temperature by adopting the high-molecular sewage low-temperature separation device provided by the invention; after the temperatureis kept for a certain time, high molecules in the sewage can be evaporated from the sewage, so that the high molecules can be attached to the inner wall of the collecting part through the air pressureeffect from bottom to top; meanwhile, the inner wall of the collecting part is in a semi-spherical shape or a conical shape, and the inner surface of the collecting part is a rough surface, so that the high molecules can be condensed at the collecting part and enter the recycling part along the collecting part; and the annular depression of the recycling part is arranged at the edge of the collecting part, so that the high-molecular compound can be collected more effectively.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a high-molecular wastewater low-temperature separation device. Background technique [0002] At present, the sewage formed by chemical production contains a large number of polymer compounds similar to pyridine and pyrimidine, such as wastewater from fertilizer factories, sewage and drainage from chemical and pharmaceutical factories, etc. However, in the prior art, the wastewater treatment process for such polymer compounds is to first pass the raw water through the sump, electrocatalytic oxidation, Fe-O 2 Oxidation, coagulation reaction tank, pH adjustment tank and upflow anaerobic sludge bed reactor, the cost of this sewage treatment process is relatively high, and a variety of chemicals need to be added. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a high-molecular waste water low-temperature se...
