Analysis On The Wastewater Treatment Engineering Technical Improvement And The Result About Daily Handing Capacity Of 400 Cubic Meters

Chemical industrial wastewater is often difficult to complete processing,therefore,not only because of its high organic(COD)pollution load,toxicity,chromaticity,the biochemical degradation can be poor common characteristics,and more waste water is produced by each enterprise has unique characteristics,even the manufacturers of the product its wastewater characteristics will be adopted by the production of raw materials,production technology and equipment,such as different and difference is very big.In this article,therefore,seeks to Jilin JX chemical company chemical wastewater treatment technology improvement,must be based on the enterprise using the raw materials,production technology,process control parameters,the wastewater quality and characteristics,the comprehensive analysis to determine the treatment technology should be adopted.In this article,therefore,seeks to Jilin JX chemical company chemical wastewater treatment technology improvement,must be based on the enterprise using the raw materials,production technology,process control parameters,the wastewater quality and characteristics,the comprehensive analysis to determine the treatment technology should II be adopted.This scheme combined the anaerobic with the aerobic method to treat of the wastewater.First removing most of the organic matter in waste water by the way of anaerobic reaction,then removing the residual organic matter in the wastewater,NH3-N and total phosphorus pollutants by aerobic method,discharge of the treated wastewater up to par.And the main structures and equipment are designed and selected.The preliminary design has been made for electrical,civil and other related professional.Finally,after the completion of the renovation project,the energy-saving treatment is made for technical equipment with the effect analysis.The discharged water of wastewater treatment station meet the secondary standard in table 4 of "Standard of sewage comprehensive discharge"(GB8978-1996).The emissions of water pollutants for enterprise is COD 4.5 t/a,and ammonia nitrogen is 0.45 t/a.
