▎ 摘　　要

NOVELTY - Compact type graphene cleaning waste water treatment system comprises denitrification zone (1), intermediate reaction zone (2), coagulation zone (3), flocculation zone (7), precipitation separator (8), effluent zone, flocculation zone, neutralizing reaction zone, flocculation zone, precipitation separator, coagulation zone, base dosing device, lime dosing device, soda dosing device, powder activated carbon dosing device, PAM dosing device and sludge dewatering zone which comprises hazardous waste storage area and gypsum storage area. USE - Compact type graphene cleaning system for treating waste water (claimed). ADVANTAGE - The compact type graphene cleaning system separates and recycles hazardous waste water and saves consumption of civil engineering investment and tube. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for for treating waste water, which involves: (A) entering graphene cleaning waste water into denitrification zone; (B) overflow into the neutralization reaction zone which is set to alkali dosing device; (C) adding sodium carbonate to adjust the pH value to 7; (D) boosting reaction mixture in neutralization tank; (E) adding waste water into coagulation zone and flocculation zone; (F) filling coagulation zone with powder activated carbon dosing device; (G) processing coagulation, flocculation reaction, and overflowing water into precipitation separator; (H) separating mud and supernatant by inclined tube which is set into coagulation area; (I) using flocculation zone in which coagulation area is set, filling by using lime dosing device (J) using flocculation zone and powder activated carbon dosing device; (K) precipitating in precipitation separator; and (L) adding precipitate sedimentation sludge into the gypsum storage area through gypsum sludge pump, concentrating and dehydrating to obtain desired product. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a compact type graphene cleaning system.
