APPARATUS AND METHOD FOR ORGANIC WASTE WATER TREATMENT

摘要

PURPOSE: A method for eliminating inorganic materials from organic waste and a facility for treating the organic waste is provided to improve the waste treating performance of a facility for treating organic waste by reducing the generation of scales in the facility and in the pipes of the facility. CONSTITUTION: A method for eliminating inorganic materials from organic waste includes the following: digested liquid is discharged from an anaerobic digesting bath(210); the discharged digested liquid is coagulated and dehydrated to form cakes; and an alkali agent is introduced into the treated liquid to adjust the pH value of the treated liquid to be in a range between 10.5 and 12 such that inorganic materials are precipitated to be eliminated. The inorganic precipitating and eliminating process is implemented in one selected from a sand filter equipped reactor, an anthracite filled reactor, and a settling bath in which supernatant and settled products are solid-liquid separated.
