This European Standard shall be given the status of a national standard, either by publication
28、of an identical text or by endorsement, at the latest by February 2017, and conflicting national standards shall be withdrawn at the latest by May 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not
29、be held responsible for identifying any or all such patent rights. This document supersedes EN 12566-7:2013. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For re
30、lationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. The differences between this version and EN 12566-7:2013 are mainly editorial changes according to the Construction Product Regulation (CPR) and declaration of power consumption and desludging duri

The standard series EN 12566 “Small wastewater treatment systems for up to 50 PT” contains the following parts (see Figure 1): Part 1: Prefabricated septic tanks; Part 3: Packaged and/or site assembled domestic wastewater treatment plants; Part 4: Septic tanks assembled
32、 in situ from prefabricated kits; Part 6: Prefabricated treatment unit used for septic tank effluent; Part 7: Prefabricated tertiary treatment unit (this document). For filtration systems, CEN/TC 165 decided to publish the following CEN Technical reports, which are considered as Code of practices an
33、d do not specify treatment requirements: Part 2: Soil infiltration systems; Part 5: Pre-treated Effluent Filtration systems.

DIN EN 12566-7:2016-12 EN 12566-7:2016 (E) 6 1 Scope This European Standard specifies requirements, test methods, the marking and evaluation of conformity for a packaged and/or
38、site assembled tertiary treatment unit (see Figure 1). It applies for tertiary treatment units that are placed on the market as complete units used for the tertiary treatment of domestic wastewater by biological, physical, chemical, electrical processes and coming from: a) units in accordance with E
39、N 12566-3 or EN 12566-6; b) installations designed and constructed in accordance with CEN/TR 12566-5. Equivalent secondary treated effluent may come from existing systems. Package and/or site assembled tertiary treatment units according to this standard consist of one or more watertight tanks withou
40、t any direct infiltration into the ground, made of concrete, corrosion resistant or coated steel, un-plasticised poly-vinyl chloride (PVC-U), polyethylene (PE), glass reinforced thermosetting plastics (GRP) based on polyester resin (UP) (GRP-UP), polypropylene (PP), polydicyclopentadiene (PDCPD) and
41、 flexible sheets (HDPE, PP, PVE and EPDM). This standard applies to tertiary treatment units for use above ground (outside the building) or buried in the ground where no vehicle loads are applied to the unit. This standard does not apply to tertiary treatment systems forming part of units covered by
42、 EN 12566-3 and EN 12566-6. This standard does not cover the systems for microorganism reduction. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
