ABSTRACT:
A small-sized, low cost to manufacture and inexpensive wastewater treating biological film tank by which wastewater produced in each home can be treated by each home. A treating tank 10 has therein multi continuous-pore soft ceramic 40. Waste or raw water is supplied into the tank from its top through a waste/raw water supplying pipe 21, and pushed up by the action of air bubble forced into the tank from its bottom through an air bubble generator 30, and then flows over through cylindrical guide 50 into the multi continuous-pore soft ceramic 40 wherein the water is purified by microorganisms which digest the nutrient in the waste or raw water. Surface area of the multi continuous-pore ceramic element 40 is about 25 times larger than that of a conventional plastic element.
