A. Focused review on water pollution prevention project in electroplaters and metal surface treatment industry upstream to Dali Bridge Monitoring Station in Dali River (A) Current heavy metal pollution by electroplaters and metal surface treatment industry in Dali City and Taiping City region who discharge wastewater into Dali River ahead of Dali Bridge monitoring station 1. Distribution of electroplaters and metal surface treatment industry upstream of Dali River Of the 149 controlled electroplaters and metal surface treatment firms upstream of Dali River, a greater part, about 120 (about 80%), is concentrated in Toubiankeng River; 96 in Taiping city and 53 in Dali City, the former outnumbering the latter; by industry category 81 being electroplater is a little more than 69 of metal surface treatment firms. 2. Analysis of permitted heavy metal pollution Toubiankeng River contributes most, followed by Caohu River and putzu River, to the heavy metal contribution by upstream branches of Dali River; each branch contributes as follows: ●No electroplaters and metal surface treatment firms set up in Dakeng River; only one electroplater in upstream of Han River (including its branch Wuniulan River) which has not operated yet. ●Currently in putzu River, 8 electroplaters and 4 surface treatment firms set up, controlled, whose permitted heavy metal productions are Cu 1.62 kg/day, Zn 50.00 kg/day, Ni 18.61 kg/day and Cr 22.58 kg/day, and permitted discharge of the produced is Cu 0.08 kg/day, Zn 0.50 kg/day, Ni 0.19 kg/day and Cr 0.35 kg/day. ●Currently in Toubiankeng River, 62 electroplaters and 58 surface treatment firms set up, controlled, whose permitted heavy metal productions are Cu 179.25 kg/day, Zn 219.94 kg/day, Ni 334.09 kg/day and Cr 894.0 kg/day, and permitted discharge is Cu 1.51 kg/day, Zn 3.00 kg/day, Ni 4.49 kg/day and Cr 9.52 kg/day. ●Currently in Caohu River, 10 electroplaters and 6 surface treatment firms set up, controlled, whose permitted heavy metal productions are Cu 0.56 kg/day, Ni 82.34 kg/day and Cr 35.48 kg/day, and permitted discharge is Cu 0.07 kg/day, Ni 0.56 kg/day and Cr 0.88 kg/day. 3. Analysis of on-site review on heavy metal pollution On-site review on heavy metal production and discharge in each branch is as follows: ●On-site sampled heavy metal production in putzu River is Cu 0.08 kg/day, Zn 0.46 kg/day, Ni 0.02 kg/day and Cr 2.52 kg/day, and on-site sampled heavy metal discharge of production is Cu 0.0003 kg/day, Zn 0.28 kg/day, Ni 0.0008 kg/day and Cr 0.009 kg/day; ●On-site sampled heavy metal production in Toubiankeng River is Cu 17.35 kg/day, Zn 58.18 kg/day, Ni 233.49 kg/day and Cr 299.33 kg/day, and on-site sampled heavy metal discharge is Cu 0.36 kg/day, Zn 3.36 kg/day, Ni 6.42 kg/day and Cr 3.11 kg/day; ●On-site sampled heavy metal production in Caohu River is Cu 0.32 kg/day, Zn 10.57 kg/day, Ni 18.29 kg/day and Cr 33.51 kg/day, and on-site sampled heavy metal discharge is Cu 0.01 kg/day, Zn 0.02 kg/day, Ni 0.12 kg/day and Cr 0.09 kg/day. (B) Analysis of document rationality and on-site rationality of the business The contents of rationality analysis in this document review include: wastewater production (discharge), power consumption, drug addition and sludge volume, and the source for projected documents is based on the comparison of the permission data and regular report records of above-mentioned controlled subjects. In principle, if the ratio of the above two data (DMR’s regular reported data divided by the permission data) is less than 50%, then the subject is taken in the list of on-site review. By the comparison results: ●Rationality analysis of wastewater production: from the comparison result, the number of businesses with product wastewater production ratio greater than 0.7 is 71 (about 57.2%), that with ratio less than 0.7 is 53 (including 29 less than 0.3, 13 in the range of 0.3-0.5 and 11 in the range of 0.5-0.7). ●Rationality analysis of power consumption: from the comparison result, the number of businesses with power consumption to wastewater ratio greater than 0.7 is 79 (about 63.7%), that with ratio less than 0.7 is 45 (including 20 less than 0.3, 10 in the range of 0.3-0.5 and 15 in the range of 0.5-0.7). ●Rationality analysis of drug addition: from the comparison result, the number of businesses with drug addition to wastewater ratio greater than 0.7 is 70 (about 56.45%), that with ratio less than 0.7 is 54 (including 36 less than 0.3, 10 in the range of 0.3-0.5 and 8 in the range of 0.5-0.7). ●Rationality analysis of sludge production: from the comparison result, the number of businesses with drug addition to wastewater ratio greater than 0.7 is 60 (about 48.3%), that with ratio less than 0.7 is 64 (including 41 less than 0.3, 13 in the range of 0.3-0.5 and 10 in the range of 0.5-0.7). (C) Use of scientific instruments to assist in monitoring and evidence collection Of the executive results of this project, a total of 40 cases of pollution were reported. Of which, 20 cases were investigated on-site, and requested to improve and issued with punishment note; also, 11 cases with scientific instruments having been used in the process of evidence collection and investigation. B. Investigation in and control of effluent contaminants from sewage plant in Central Science Park (including Daya Base and Houli Base) and Dali Industrial Zone (A) The 3-quarter sampling operations from the sewage plant effluent in Central Science Park in Daya and Houli (Rexchip Electronics Corp. being the sampling subject for the time being, as the Houli Sewage Plant has not yet officially been in operation and will replace Rexchip when starting to officially operate), and Dali Industrial Zone have been completed in July, September and November. (B) In the continued and automated monitoring of water quality in effluent of sewage plants in Daya Base, Houli Base and Dali Industrial Zone, at least water temperature, pH value and electric conductivity are measured at every monitoring site for at least 80 days. In this year, the installation has been completed for 80 days at Daya Base, 97 days at Houli Base in Central Science Park (including Rexchip Electronics for 7 days) and 87 days at Dali Industrial Zone. C. Auxiliary tasks of the evaluation and administrative operation: Press release has been published 14 times (two were news on newspaper), the contents of which include promotion of regular night-soil treatment, permits renewal procedure, underground pipe investigation, reinforced investigation and management of pollution, reinforced management of water reservoirs (rooftop tank) and potable water, and revision of on-line declaration for prevention of water pollution.
