Study On Mathematics Model Of SBR And Applied To Gelatin Wastewater

The characteristics of glutin manufacturing wastewater are high contents of calcium, alkali and organic albumen, all of which, calcium and alkali come from the working procedure of lime-soaking in glutin manufacturing. Glutin lime-soaking wastewater accounts for a heavy proportion during glutin manufacturing and jeopardizes seriously, so it is relatively difficult to treat. Because there is high content of organic nitrogen and phosphorus in glutin picking wastewater, the removal of nitrogen and phosphorus in the wastewater is of significance to prevent water-body from eutrophication.This study first analyzes and discusses of substrate degradation process of in SBR method , compares among several different SBR methods, and improve the dynamic formula of substrate degradation and mathematics models for the quantitative change of sludge microorganism. Based on this, the author deals with glutin manufacturing wastewater.According to the glutin manufacturing technics, the experiment makes the glutin wastewater by simulation and processes drainage quantity Stat, and water quality analysis.At first, according to different burthen, author has studied the single-stage SBR technics of glutin wastewater and this establishes a foundation for next study of the two-stage SBR denitrification compound technics. The experiment has been done on the treatment of glutin wastewater and the experimental research results show that:â—‹1 In compound liquid of active sludge, there is a close relation among pH,Ca 2+and CaHPO 4or Ca 3 (PO4)2. When the accumulation of CaHPO 4or Ca 3 (PO4)2 deposit is more and more, it will have a strong influence on the active sludge, and it maybe the active sludge system fall apart;â—‹2 For some active sludge system, when there is a lot of PO 43+, Ca 2+concentration must keep certain concentration below. When Ca 2+concentration is over the certain concentration, it will rapidly make CaHPO 4or Ca 3 (PO4)2 sediment more and more in the active sludge system;â—‹3 Reactorâ…¡is stronger in treatment with organic contamination, when reactorâ…¡and reactorâ… alone run all by itself. If the wastewater quality parameter is similar, reactorâ…¡has...
