Sewage disposal agent, sewage purifier, washing machine with purifier, and sewage purifying method

A washing machine incorporating a purifier and provided with a washing process for removing dirt on laundry with washing water containing a detergent and a first rinsing process for removing the detergent from the laundry, comprising:

• a reservoir section for storing washing water drained from said washing machine;
• and
• a polluted water purifier for purifying the washing water by collecting a pollutant present in the washing water stored in the reservoir section by flocculating the pollutant,
• wherein the washing water used in the washing process and rinsing water used in the first rinsing process is stored together in the reservoir section and is purified simultaneously by the polluted water purifier.

• a polluted water purifier for purifying the washing water by collecting a pollutant present in the washing water stored in the reservoir section by flocculating the pollutant,
• wherein the washing water used in the washing process is purified by the polluted water purifier and is then used in the first rinsing process, and then rising water used in the first rinsing process is purified by the polluted water purifier.

A washing machine incorporating a purifier, comprising a polluted water purifier for collecting a pollutant present in polluted water by flocculating the pollutant with a flocculant,

• wherein the polluted water purifier comprises:
• a mixer for mixing the polluted water with the flocculant and air;
• an agitator for agitating the polluted water, containing the flocculant and the air, that flows into a cylindrical agitation chamber along an inner surface thereof by making the polluted water into a spiraling stream so that flocks formed by the flocculant hold bubbles;
• and
• a separator, connected to the agitator, for temporarily storing the polluted water and for separating the flocks holding the bubbles.

A washing machine incorporating a purifier, comprising a polluted water purifier for collecting a pollutant present in polluted water by flocculating the pollutant with a flocculant,

• wherein the polluted water purifier comprises:
• a polluted water tank for storing the polluted water;
• a first mixer for mixing the polluted water with a primary flocculant to produce primary flocks,
• a second mixer for mixing the polluted water containing the primary flocks with a secondary flocculant and air to produce secondary flocks;
• an agitator for agitating the polluted water containing the flocculant and the air so as to make the secondary flocks grow larger, and
• a separator for separating the secondary flocks thus grown,
• wherein the polluted water tank, the first mixer, the second mixer, the agitator, and the separator are coupled in this order to form a circulation path that leads back to the polluted water tank.
