Method and apparatus for treating sewage

摘要

Apparatus for sewage treatment, comprising: at least one tank (13), at least one inlet branch (14) to the tank (13), at least one outlet branch (15) from the tank (13), at least one microwave generator (9a) able to subject the sewage present internally of the tank (13) to at least one temperature raising treatment, at least a cooling circuit (19) of the microwave generator (9a), at least one blowing device (9b) connected to the tank (13). Blowing device (9b) is connected to an outlet (26) of the cooling circuit (19) and sending the heated gases arriving therefrom into the tank (13).

1. An apparatus for sewage treatment, comprising:
at least one tank (13); at least one inlet branch (14) to the tank (13); at least one outlet branch (15) from the tank (13); at least one microwave generator (9a) configured to subject sewage present internally of the tank (13) to at least one temperature raising treatment; at least a cooling circuit (19) of the microwave generator (9a); and, at least one blowing device (9b) connected to the tank (13), said blowing device (9b) being connected to an outlet (26) of the cooling circuit (19) and sending heated gases arriving from the outlet (26) of the cooling circuit (19) into the tank (13), wherein the tank (13) comprises a plurality of chokes (16), each choke defining a respective forced passage (17) for sewage, wherein the microwave generator (9a) is externally engaged to the tank (13), at least at one of the forced passages (17), the microwave generator (9a) being configured to generate electromagnetic waves in a direction of the forced passages (17), and wherein the tank (13) comprises, at each of the forced passages (17), at least one window (18) that is radio-transparent to frequencies of the electromagnetic waves (18).
