Limit emissions of hexavalent chromium, nickel, cadmium, silver, lead, mercury and other toxic pollutants

Central and Northern soldiers, the development of Environmental Science and Technology Co., Ltd. (hereinafter referred to as soldiers in the northern environment, companies) editor in chief of the national standard “electroplating emissions Standard “(GB21900-2008) through the relevant approvals and formal implementation. This also marks the electroplating enterprises ceased to perform, “Integrated Wastewater Discharge Standard” (GB8978-1996) and “Integrated emission standard of air pollutants” (GB16297-1996) in the relevant regulations.

In the scope of the first release of GB21900-2008 standard applies to existing electroplating enterprises of water pollutant discharge management, management of air pollutant emissions. Such as electroplating enterprises to build the project’s environmental impact assessment, environmental protection, facility design, environmental protection, acceptance and put into operation after the completion of the water, air pollutant discharge management; the new location of pollution sources and special protected areas and management of existing pollution sources . In addition, the standard also applies to anodic oxidation surface treatment facilities.

in specific content, the standard provides facilities for electroplating enterprises and enterprises owned electroplating electroplating water pollutants and air pollutants emission limits and so on. If enterprises to the town sewage treatment plants discharge wastewater drainage system, toxic pollutants, hexavalent chromium, nickel, cadmium, silver, lead, mercury monitoring provisions in the standard location of the implementation of the corresponding emission limits; and other pollutants emission control requirements from the enterprise and urban sewage treatment plant sewage treatment capacity in accordance with its agreed upon or implement the relevant standards, and report to the local environmental protection department for the record; urban sewage treatment plant shall ensure that discharge of pollutants meet relevant emission standards. Construction project intends to set up sewage treatment plants discharge of urban waste water drainage system, by the construction unit and urban sewage treatment plants according to the preceding paragraph shall apply.

experts, electroplating industry is versatility, use the wide cross-sectoral and inter-departmental major processing industries, technically speaking, the electroplating industry, the use of a large number of strong acid, alkali, heavy metal solutions, as well as cadmium, cyanide, etc. toxic and hazardous chemicals discharged in process waste water, waste gas and waste residue if more than the standard value, it is likely to cause environmental pollution; combined with many small and medium enterprises poorly equipped and old, but also primarily manual-based, therefore, strengthen the electroplating pollution Emission of the formulation of national standards is particularly important.

soldiers in the northern environment, pollutant treatment in electroplating industry has a more than 30 years of technological accumulation. In recent years, for electroplating enterprises to focus, the phenomenon of increasing division of labor and cooperation, the company actively promote the plating clean production, development and promotion of low concentration, low-pollution of the plating process, countercurrent washing process, put forward a unified collection of contaminants on the plating and concentrate disposal methods, development and application of a number of advanced purification and recovery technology, has undertaken a number of national standards, standardized preparation, is the industry’s technical backbone enterprises. State Environmental Protection Administration of the company identified as “electroplating pollutant discharge standard” editor in chief of unit. Industry experts said that after nearly five years of efforts, the soldiers of the northern environment, the company developed standards for the promotion of electroplating industry technical upgrading and development of the industry will have a profound effect.

电镀正式实施污染物排放标准的国家

限制排放的六价铬，镍，镉，银，铅，汞和其他有毒污染物

中部和北部兵，环境科学与科技有限公司开发（以下简称士兵在北部环境中，公司）主编的国家标准电镀排放标准“（GB21900 - 2008”总编辑）通过有关审批和正式实施。这也标志着电镀企业不再执行“污水综合排放标准”（GB8978 - 1996）和“大气污染物综合排放标准”（GB16297 - 1996）的有关规定执行。

适用于在GB21900的第一个版本的范围- 2008标准对现有电镀企业的水污染物排放管理的空气，污染物排放管理。如电镀企业后，兴建完成的水，空气污染物排放管理项目的环境影响评价，环保，设施设计，环保，验收并投入使用，对污染源和特别保护区和管理的新定位现有污染源。此外，该标准也适用于阳极氧化表面处理设施。

的具体内容

，该标准规定了电镀企业，企业拥有的设施电镀电镀水污染物和大气污染物排放限值等。如果对城镇污水处理厂排放污水的排水系统的企业，有毒污染物六价铬，镍，镉，银，铅，在相应的排放标准的执行标准位置汞监测的规定;和其他污染物的排放控制要求的企业和城市污水处理厂污水与其商定或执行有关标准，向当地备案环境保护部门根据处理能力，城市污水处理厂应保证排放污染物达到相关排放标准。施工项目计划成立由建设单位和城镇污水处理厂污水处理厂，城市污水排放系统排放，按照前款规定执行。

专家，电镀行业通用性，使用广泛的跨部门和跨部门的主要加工工业，从技术上讲，电镀业，一个在强酸，强碱，重金属，大量使用的解决方案，以及如镉，氰化物等有毒有害化学品的过程中排出的废水，废气，废渣，如果超过标准值，更可能造成环境污染;与许多中小型设备简陋和老企业，但相结合也主要是手动的，因此，加强国家标准的制定电镀污染排放尤为重要。

北部环境的士兵，在电镀工业污染物处理的技术积累了逾30年。近年来，为电镀企业集中，增加了分工合作的现象，该公司积极推动电镀清洁生产，发展和低浓度，低污染的电镀工艺，逆流洗涤过程中，提出了促进统一的污染物收集电镀集中处置方法，开发和先进的净化和回收技术的应用数量，采取了国家标准，规范编制人数，是行业的技术骨干企业。国家环保总局列为“电镀污染物排放标准”的主编单位确定的公司。业内专家说，经过近5年的努力，北部环境的士兵，公司制定了对电镀行业的技术升级和行业标准，促进发展有深远的影响。08.11.5
