Abstract
A sewage and wastewater treatment plant which comprises a bioreactor having an anaerobic treatment tank for anaerobic treatment, an aerobic contacting tank and a microorganism separation tank located in between the anaerobic and aerobic tanks respectively. In the anaerobic and aerobic tanks a media is provided in a layered honeycomb type arrangement for distributing the wastewater and sewage to be treated and for adherence of microorganisms.
Claims7
A sewage and waste water treatment system comprising:
- a compartmentalized bio-reactor having an inlet for introduction of influent into a first reaction compartment, the first reaction compartment comprising anaerobic microorganisms and having a layered media in an upper region thereof, positioned below the inlet, for distribution of the influent evenly throughout the first reaction compartment;
- a second reaction compartment comprising aerobic microorganisms and having a layered media for adherence of the aerobic microorganisms and a precipitation portion in an upper region thereof for separating out purified water from the system;
- and a middle compartment located between the first and second reaction compartments having a gas-solid separator for separation of rising gas from the anaerobically treated influent.
A sewage and waste water treatment system comprising:
- a bio-reactor having a series of horizontally spaced compartments;
- a first reaction compartment of the bio-reactor having an inlet for influent to be treated, anaerobic microorganisms and a layered media, in which compartment the influent is treated anaerobically;
- a second reaction compartment of the bio-reactor having aerobic microorganisms and a layered media, in which compartment the waste water is treated aerobically;
- a precipitation portion of the bio-reactor, in which purified waste water is separated out of the bio-reactor;
- and
- a middle compartment, located between the first and second reaction compartments, having a gas-solid separator for separating rising gas from anaerobic microorganisms.
