Abstract

When quota load ammounts were calculates by the pollution total amount management system carrying out from two thousands five july, discharged load amounts of running J sweage treatment plant are expected to occupy most of Jeonju zone load amounts. It is necessary to study rational inflowed concentration of industrial wastewater for increase of treatment effects of sweage treatment plant programmed advanced wastewater treatment conversion. Therefore this study carryed out using industrial wastewater of A co. inflowed about 70% to J sweage treatment plant. The study results is as follows.
A monthly average concentration of draing water of eight co. placed the second industrial complex of jeonju is enough satisfied draining water quality acceptable limit value(BOD5, CODMn, SS, 200mg/L, TN 60mg/L, TP 8mg/L) by BOD5 3.3~26.1mg/L, CODMn 22.2~91.8mg/L, SS 7.3~35.3mg/L, TN 3.4~20.5mg/L, TP 0.1~4.8mg/L.
Industrial wastewater amounts inflowed within jeonju sewage treatment plant occupy a fifth part of sewage about 55,000ton/day. After due consideration, wastewater mixed draining water of industrial wastewater and sewage were applied for activated sludge process and CNR process. The results two process indicated not distingished differance of treatment efficiency, and it satisfied not BOD5 of the discharged water quality standard value of sweage treatment plant to intensify hereafter.
Wastewater mixed by 1:5 draining water of industrial wastewater and sewage and wastewater mixed by 1:5 primary sedimataion water of industrial wastewater and sewage applied CNR precess respectively. Effluent concentration of the latter is lower than the former all items and satisfied BOD5 10mg/L, CODMn 40mg/L, SS 10mg/L, TN 20mg/L, TP 2mg/L of discharged water quality standard value of sweage treatment plant to intensify hereafter.
Wastewater mixed by 1:5, 1:3 and 1:1 primary sedimataion water of industrial wastewater and sewage applied CNR precess respectively. BOD5, CODMn, SS of dischared water of wastewater mixed by 1:1 and SS of dischared water of wastewater mixed by 1:5, 1:3 exceeded discharged water quality standard value of sweage treatment plant. If that water should apply sand filtration process, will satisfy discharged water quality standard value of sweage treatment plant.
To investigate advenced treatment efficiency of CSBR process wastewater mixed by 1:1 primary sedimataion water of industrial wastewater and sewage applied. Effluent concentration of CSBR process is lower than CNR process and satisfied not discharged water quality standard value of sweage treatment plant to intensify hereafter.
In conclusion if it should treat wastewater mixed wastewater draining in jeonju industry complex of A co. and sewage, CNR process 1, 2 steps process wastewater mixed by 1:3~5 primary sedimataion water of industrial wastewater and sewage is best. satisfied discharged water quality standard value of sweage treatment plant to intensify hereafter and it is estimated that pollution total amount management system carried out hereafter is possible preparation.
