INDEPENDENT TREATMENT SYSTEM FOR TREATING THE WASTEWATER OF THE CONSTRUCTION SITE WITH THE CHEMICAL COAGULATION TECHNOLOGY

摘要

A WASTEWATER TREATMENT SYSTEM DEALS WITH THE CONSTRUCTION SITE WASTEWATER USING CHEMICAL COAGULATING TECHNOLOGY. A CHEMICAL DOSING PUMP (4) PUMPS THE LIQUID CHEMICAL IN A CHEMICAL DOSING TANK (1) INTO A REACTION TANK (2). AN AGITATOR (5) STIRS AND COAGULATES THE LIQUID CHEMICAL IN THE TANK (2) WITH THE PRELIMINARY PRECIPITATED WASTEWATER IN THE TANK (2). THE STIRRED AND COAGULATED WASTEWATER IS THEN DIRECTED INTO SEDIMENTATION TANK (3) TO SEPARATE THE TREATED WATER WITH COAGULATED PARTICLES. THE TREATED WATER IS THEN GUIDED OUT FROM THE UPPER PART, AND THE SLUDGE IS DISCHARGED FROM THE LOWER PART THEREOF WITH THE AIR COMPRESSOR 6 OPENING THE AUTOMATIC VALVE (7). THE DIFFERENT ELEMENTS MAY BE ASSEMBLED TO BE ATTACHED TO ONE SUPPORTING BOARD. THE ASSEMBLY MAY BE TRANSPORTED TO DIFFERENT OPERATING SITE. THE SYSTEM IS SIMPLE IN STRUCTURE, EASY TO USE. THE TREATED WATER IS UP TO THE ENVIRONMENT PROTECTION AUTHORITIES REQUIREMENT AND MAY BE REUSED IN VARIOUS CONSTRUCTION OPERATIONS. FIGURE 1
