WASTE WATER RESOURCE-TREATMENT APPARATUS

摘要

The present invention relates to a flocculation tank in which raw water is introduced, a first flocculant is added and stirred rapidly, a coagulation tank in which flocculated flocs generated by slow stirring of raw water overflowing in a mixing tank are precipitated, The second flocculant is added so that the raw water and micro flocs passing through the screen net are re-flocculated, the raw water overflowed in the neutralization tank and the neutralization tank rapidly stirred, and the flocculated flocs are settled A sedimentation tank for circulating sedimented flocs to the screen net again, and a filtration tank for purifying raw water overflowed from the sedimentation tank and circulating the purified raw water back to the mixing tank.
