Zero discharge of wastewater process
,,,,,,,,,,,,,,,,,,,,,,, V given corrosion rate of steel with corrosion inhibitor. Test results are as follows: When the inhibitor concentration of 125ppm, the of A, A steel corrosion rate of 100%. Apparent steel with excellent, bright as ever. Example 2 methods and the implementation of the composition of the same embodiment inhibitor l, the concentration of inhibitor lOOppm, the rate of corrosion of steel A 99.73%. Apparent steel with good,[link widoczny dla zalogowanych], bright as ever. 4 2002 Water Information Report 43 emissions, waste water treated recycled water as a supplementary water,[link widoczny dla zalogowanych], can fully improve water use efficiency, reduce water consumption; also added to the water cycle by a certain amount of fungicide, water stabilizer to achieve the salt balance of the whole system, truly zero emissions. Figure 1 is the invention of the wastewater treatment process flow diagram of total system. Figure 2 is the invention of the integrated treatment of the wastewater system connection diagram. Figure 3 is the invention of chemical and water treatment systems in the connection diagram. Figure 4 is the invention of a gray water system flushing connection diagram. Figure 5 is the invention of the coal washing water system connection diagram. The following embodiments of the invention with further description. The zero discharge of wastewater processes, including chemistry and water treatment systems, washing out the gray water treatment system, coal washing water treatment system, waste water treatment system,[link widoczny dla zalogowanych], and add alum integrated system in which chemistry and water treatment system, a gray wash water coal washing water treatment systems and closed-loop system for the three small systems. 1 main building of waste water drainage through the pool drain pump 5, the waste water sewage tank 2 through the sewage purification station 4 and the three closed-loop system to produce a small amount of small overflow water and industrial wastewater recycling summary overflow pool 3 integrated wastewater treatment system to The overflow reservoir 6, 6,[link widoczny dla zalogowanych], overflow reservoir oil and floating debris can play role in isolation, then the liquid pump 7 hit, 12 clarifiers, intermediate-treatment system plus alum, followed by non-valve filter 13 to the cooling tower 14 into the circulating water as makeup water, and according to need water supply pump 15 to supply water to ensure the basic stability of water flow, while adding a certain amount of circulating water disinfectant, water quality stabilizer, fungicides used in circulating water plus fungicide 1227 combined with the stability of the CIO to address the phenomenon of microbial growth in water and control the concentration ratio in a dose 10 times less pay,[link widoczny dla zalogowanych], making the cooling tower 14 through evaporation and wind carry , bring the water content of salt content and supplemental balanced to achieve the salt balance of the entire system to prevent the condenser to generate new corrosion and fouling. Dosing alum storage tank system consists of 8, 9, metering box alum, alum solution tank 10 and 11 composed of alum dosing pumps, alum dosing pump 11 by linkage, two alum dosing pump 11, respectively, sewers and water mains plus complement medicine, set in the sewage pipe flow signal, respectively, through the flow of alum dosing pump 11 starts. Water through the clarifier 12 to add liquid ferric sulfate as coagulant in the water hydrolysis, neutralization, polymerization and other chemical reactions, flocculation substances generated, through the bridge, settlement, netting can play a role in bleaching, in addition to bacteria, in addition to radioactive elements, heavy metals, reduce the CoD, BOD results. To ensure clear results, the settling pond 12 to add the ramps. Chemistry and waste water treatment system for acid-base is no longer, waste water and the pool of 16 Chinese and 17 through the siphon. Hit by the bottom 18 sewage pump liquid pump 19, directly as a slag water to add water, pipes are lined with plastic pipe, a small amount of overflow water through the ditch remitted overflow reservoir 6. Washing ash wastewater treatment system by the open ditch in the import liquid pump 21 pool 22, then increase by the liquid pump 23 into the dewatering bin 24, then by the back wash tank 25 to pump 20, as a gray wash water reuse remit a small amount of overflow water through the ditch overflow reservoir 6. Coal washing waste water treatment system in the convergence of the entire pool of 26, with a mixed flow pump 27 to the bridge and transfer station to the wastewater sludge sedimentation tank to fight step by step 28, closed after precipitation of water re-use, small amounts of excess remitted by the trench overflow water reservoir 6. The zero discharge of wastewater process to test analysis Xiaoshan Power Plant's water, all kinds of waste are not to Puyang emissions to 300 tons / 4,1 ~,-t dollars, can reduce the outward about 2.63 million tons of waste water / year, while reducing water to 2.19 million tons Puyang / year, the annual economic output of about 17 to million. Water Information Report (Total 107) Figure 1 wastewater treatment system flow chart of Figure 2, the total integrated wastewater treatment system connection diagram 53, and water chemistry at the system jj [access, J means 5 Handling: in the submerged system jjI access at 1 994 total quiet ... help flush water treatment system connected, J �� intent
