Abstract

Provided are a household toilet waste treatment system and a method of treating toilet waste using the same, the household toilet waste treatment system comprising a solid-liquid separation toilet, a biological treatment apparatus, a sterilization apparatus, and a combustion apparatus. The combustion apparatus complements a slow biological treatment apparatus to allow continuous treatment of the household toilet waste in a unit space without long-distance piping connections.

First claim

The invention claimed is:

1 . A household toilet waste treatment system comprising:
a solid-liquid separation toilet for separating toilet waste into liquid toilet waste and solid toilet waste; a biological treater for biologically treating the liquid toilet waste transported from the solid-liquid separation toilet, wherein the biological treater comprises a bioreactor and a precipitation tank for precipitating biotreated toilet waste; a sterilizer for sterilizing biotreated liquid waste transported from the biological treater; and a combustor for combustion of the solid toilet waste transported from the solid-liquid separation toilet and biotreated solid waste transported from the biological treater, wherein the precipitation tank is connected to
the bioreactor to return a precipitate to the bioreactor, or
the combustor to transport a precipitate to the combustor.

2 . The household toilet waste treatment system of claim 1 , wherein the solid-liquid separation toilet comprises a liquid collector for accommodating the liquid toilet waste and a solid collector for accommodating the solid toilet waste.

3 . The household toilet waste treatment system of claim 1 , wherein the solid-liquid separation toilet is configured to have a solid separation rate of 50% to 100% and a liquid separation rate of 50% to 100%.

4 . The household toilet waste treatment system of claim 1 , wherein the bioreactor comprises: an anoxic bioreactor (A) and an oxic bioreactor (O); an anoxic bioreactor (A), an oxic bioreactor (O), and an anoxic bioreactor (A); an anaerobic bioreactor, an anoxic bioreactor (A), and an oxic bioreactor (O); an anoxic bioreactor (A), an oxic bioreactor (O), an anoxic bioreactor (A), and an oxic bioreactor (O); an anaerobic bioreactor, an oxic bioreactor (O), an anoxic bioreactor (A), an oxic bioreactor (O), and an anoxic bioreactor (A); an MUCT bioreactor; an UCT bioreactor; a sequencing batch reactor; a partial nitrification bioreactor and an Anammox bioreactor; an Anammox bioreactor; or a combination thereof.

5 . The household toilet waste treatment system of claim 1 , wherein the bioreactor comprises an anaerobic digestion (AD) bioreactor.

6 . A household toilet waste treatment system comprising:
a solid-liquid separation toilet for separating toilet waste into liquid toilet waste and solid toilet waste, a biological treater for biologically treating the liquid toilet waste transported from the solid-liquid separation toilet, wherein the biological treater comprises a first bioreactor that does not comprise an anaerobic digestion (AD) bioreactor and an anaerobic digestion (AD) bioreactor, a sterilizer for sterilizing biotreated liquid waste transported from the biological treater, and a combustor for combustion of the solid toilet waste transported from the solid-liquid separation toilet and biotreated solid waste transported from the biological treater, wherein the AD bioreactor is arranged in the front of the first bioreactor that does not comprise an anaerobic digestion (AD) bioreactor so that the liquid toilet waste transported from the solid-liquid separation toilet can flow into the AD bioreactor, and an organic matter can be solubilized through anaerobic digestion.

7 . The household toilet waste treatment system of claim 5 , wherein the precipitation tank is connected to the AD bioreactor and precipitates anaerobically digested liquid toilet waste transported from the AD bioreactor.

8 . The household toilet waste treatment system of claim 1 , wherein the sterilizer comprises an ozone generator, an ultraviolet irradiator, or a combination thereof.

9 . The household toilet waste treatment system of claim 1 , wherein the combustor further comprises a dryer for drying the toilet waste.

10 . The household toilet waste treatment system of claim 1 , further comprising a dewaterer for dewatering the solid toilet waste transported from the solid-liquid separation toilet to the combustor, the biotreated solid toilet waste transported from the biological treater to the combustor, or a combination thereof.

11 . The household toilet waste treatment system of claim 1 , wherein the precipitation tank is connected to the bioreactor to return the precipitate to the bioreactor.

12 . The household toilet waste treatment system of claim 1 , wherein the biological treater is connected to a water reservoir so that biotreated toilet water can be transported to the water reservoir.

13 . A household toilet waste treatment system comprising: a solid-liquid separation toilet for separating toilet waste into liquid toilet waste and solid toilet waste; a biological treater for biologically treating the liquid toilet waste transported from the solid-liquid separation toilet; an anaerobic digestion (AD) bioreactor for biologically treating the solid toilet waste transported from the solid-liquid separation toilet under anaerobic conditions; a sterilizer for sterilizing biotreated liquid waste transported from the biological treater; and a combustor for combustion of anaerobically digested solid toilet waste transported from the anaerobic digestion bioreactor and biotreated solid toilet waste transported from the biological treater.

14 . The household toilet waste treatment system of claim 13 , wherein the biological treater further comprises a precipitation tank for precipitating biotreated toilet waste, and wherein the precipitation tank is connected to a bioreactor of the biological treater to return a precipitate to the bioreactor, or is connected to the combustor to transport a precipitate to the combustor.

15 . The household toilet waste treatment system of claim 13 , further comprising a solid-liquid separation bioreactor for separating the anaerobically digested solid toilet waste transported from the AD bioreactor into solid waste and liquid waste, wherein the AD bioreactor is connected to the solid-liquid separation bioreactor to transport the anaerobically digested solid toilet waste to the solid-liquid separation bioreactor.

16 . The household toilet waste treatment system of claim 15 , wherein the solid-liquid separation bioreactor is connected to the combustor so that the solid waste can be transported to the combustor.

17 . The household toilet waste treatment system of claim 13 , wherein the AD bioreactor is connected to the biological treater so that liquid components of the anaerobically digested solid toilet waste can be transported to the biological treater.

18 . The household toilet waste treatment system of claim 13 , further comprising a solid-liquid separation bioreactor for separating the anaerobically digested solid toilet waste transported from the AD bioreactor into solid waste and liquid waste, wherein the AD bioreactor is connected to the solid-liquid separation bioreactor to transport the anaerobically digested solid toilet waste to the solid-liquid separation bioreactor, and the solid-liquid separation bioreactor is connected to the biological treater to transport liquid components of the anaerobically digested solid toilet waste to the biological treater.

19 . A method of treating toilet waste, the method comprising throwing toilet waste into a solid-liquid separation toilet of the household toilet waste treatment system of claim 1 .
