Repair and Maintenance： Operation management personnel and maintenance personnel should be familiar with electromechanical equipment’s maintenance regulations。 Keep structures like tank and container and equipment water surface free of any floater and tank wall and discharge weir notch clean and intact。 centrifugal pump with accumulated operation time of 4000h。 Lifting pump P2856 in discharge tank discharges waste according to the flow of 2m3/hr. Chapter Six Main Disposal Structure and Equipment Debug and Overall Linked Operation：（By clear water）After civil work of waste disposal project and equipment piping installation pleted and accepted, every disposal structure and equipment should undergo single unit debug and overall linked operation by clear water. Purpose： To observe if every disposal structure, electromechanical equipment and relevant transfer piping and ditch meet respective performance requirements, test and check if equipment and its pipe fittings operates abnormally due to mailinstallation, which should be solved immediately。 After a certain period of operation, check airproof at water pump filing or oil sealing with necessary treatment。 Periodically roundinspect the operation of structure, electromechanical equipment, instrument and device。 Frequently check and fasten connecting parts in various equipment and replace consumable part in coupler periodically。TOLEDO SBR tank（S2850/2855 Concrete tank on the ground）Function: A main structure for waste biological treatment by making use of activated sludge method. As a biological reactor, SBR tank is used to degrade organic substance in the waste continuously within a reaction cycle.Quantity： 2 units for alternate operationEquipment dimension： 2500X2500X4500 mm，concrete structure。l Waste coagulation reaction and deposition；l Waste PH adjustment；l Waste biochemical treatment；l Disposed water filtering；l Water measured discharge；l Sludge disposal. Waste quantity:Industrial waste disposal capacity is designed as：20m3/d；designed flow is 2m3/H Waste quality index： Based on relevant data supplied by owner, industrial waste’s quality is designed as： PH: CODcr: 500020000 mg/ L； BOD5: 5004000 mg/ L； SS: 350016000 mg/ L； Standards of discharged water quality： As required by owner, waste should reach the following standards after disposal： CODcr =500~2000 mg/L； SS Removal ratio 95%； Cr ≤ mg/ L； Zn ≤ mg/ L； Cu ≤ mg/ L Pb ≤ mg/ L As ≤ mg/ LWaste up to standards will be discharged into municipal pipe network. Process flow and specifications Specifications on process flow： Please refer to the attached process flow chart for waste disposal process flow and the brief description is as follows: Industrial waste will be lifted into adjustment tank S2801 for quality and quantity adjustment through inlet pipeline. With one jet blender in the tank, part of outlet water from lifting pump P2801 in adjustment tank flows back to adjustment tank for blending to prevent suspended substance in the waste to deposit in the tank. The lifting pump in adjustment tank is started or stopped by liquid level transmitter LICA2801S in the tank. When liquid in the tank reaches high level, lifting pump in it will start automatically and lift the liquid in adjustment tank into coagulation tank R2810A. And when liquid in the tank reaches low level, lifting pump will stop automatically. Whether liquid at highhigh level or lowlow level, system will send out alarm automatically. Coagulant FeCl3 will be added into coagulation tank R2810A and blended by blender A2810A so as to mix waste and coagulant quickly. Meanwhile, a PH meter PH2810A is installed in coagulation tank to test PH value in the tank. Liquid from coagulation tank flows into reaction tank R2810B, into which lime milk will be added. Through blender A2810B, lime milk and waste will be mixed quickly and another PH meter is installed in reaction tank PH2810B to control the input amount of lime milk. By adjusting input amount of lime milk, heavy metal and part of organic substance in waste will react with coagulant to form floc within an appropriate PH range.Liquid from reaction tank flows into flocculation tank R2810C, in which macromolecule flocculant PAM will be added. Through blender A2801C, PAM will mix with waste quickly. Floc and deposit in waste will bee larger floc through effect of netting and bridging generated after flocculant PAM dissolves. Liquid from flocculation tank flows into vertical flow type deposition tank V2315 for liquid and solid separation. The upper clear liquid flows to the following process for further disposal through overflow weir while sludge deposits to the sludge filler and is lifted into sludge tank V2820 for further disposal through sludge pump P2815 in deposition tank. Liquid from deposition tank flows into PH adjustment tank V2840, in which H2SO4 will be added. T
