Abstract

PURPOSE: To remove phosphorus, chromaticity, and organic material from treated liquid of excretions or those from livestock by a method wherein these bilogical treated liquid is coagulated and settled by use of calcium chloride and high molecular coagulant.
CONSTITUTION: Biological treated liquid f excretions or those from livestock is mixed with calcium chloride and high molecular coagulant to form coagulated settlement. Then, its supernatant is again added with calcium chloride and high molecular coagulant to form coagulated settlement, so that chromaticity and organic material is removed from the biological treated liquid. As an approximate target for adding quantities of calcium chloride and high molecular coagulant, it is preferable to use about 2,000ppm calcium chloride and about 15ppm high molecular coagulant against about 2,500W3,000ppm chromaticity.
