BS EN 12255-15:2003 污水处理厂.活性污泥处理厂曝气池清水中充氧量的测量

This European Standard specifies the non-steady state measurement of the oxygen transfer rate and the oxygen transfer efficiency of aeration systems in activated sludge aeration tanks (see EN 12255-6) when filled with clean water. NOTE 1 This is known as the clean water test. NOTE 2 Since the method is based on completely mixed tanks or tanks with evenly distributed aerators or diffusers test results from certain aeration installations can be incorrect. NOTE 3 Under process conditions with mixed liquor the oxygen transfer rate and the oxygen transfer efficiency can be different from the clean water test results. This is expressed by the α-factor.

BS EN 12255-13:2003 废水处理厂.化学处理.通过沉淀作用/絮凝作用处理废水

This European Standard specifies the requirements for chemical treatment of wastewater by precipitation/flocculation for removal of phosphorus and suspended solids. The application of polymers is not described in this European Standard. Differences in wastewater treatment throughout Europe have led to a variety of practices being developed. This standard gives fundamental information about the practices; this standard has not attempted to specify all available practices. Detailed information additional to that contained in this standard may be obtained by referring to the bibliography.

DIN EN 12255-1:2002 污水处理厂.第1部分:通用施工原则

This European Standard specifies general requirements for structures and equipment as they relate to wastewater treatment plants for a total population of more than 50 PT. The primary application is designed for wastewater treatment plants for the treatment of domestic and municipal wastewater. Requirements for structures which are not specific for wastewater treatment plants are not within the scope of this European Standard. Other ENs may apply. Equipment which is not solely used in wastewater treatment plants is subject to the applicable product standards. However, specific requirements for such equipment when used in wastewater treatment plants are included in this part. General principles of building construction, mechanical and electrical engineering are not subject of this standard. This European Standard does not cover the design of treatment processes.

BS EN 12255-9:2002 污水处理厂.气味控制和通风

This European Standard specifies design principles and performance requirements for odour control and associated ventilation for wastewater treatment plants. The primary application is for wastewater treatment plants designed for the treatment of domestic and municipal wastewater for over 50 PT. Differences in wastewater treatment throughout Europe have led to a variety of systems being developed. This standard gives fundamental information about the systems; this standard has not attempted to specify all available systems. Detailed information additional to that contained in this standard may be obtained by referring to the Bibliography.

DIN EN 12255-8:2001 污水处理厂.第8部分:污泥处理和储存

The document gives design principles and specifies construction requirements for sludge treatment and storage facilities in wastewater treatment plants. Sludge treatment and storage is an integral part of wastewater treatment and utilisation. It may be subject to a variety of regulations dependent upon the site of the treatment plant and the proposed routes for use or disposal. For new works or major upgrading an environmental impact assessment should carried out.
