Chapter 1 General Provisions
Article 1.0.1 This standard is formulated in order to achieve basic uniformity in the design of ancillary buildings and ancillary equipment of urban sewage treatment plants (hereinafter referred to as sewage plants), strictly control the construction scale, and correctly grasp the construction standards.
Article 1.0.2 This standard applies to the design of ancillary buildings and ancillary equipment of newly built, expanded and renovated sewage treatment plants. It does not apply to the design of ancillary buildings and ancillary equipment of the competent departments (companies or management offices, institutes) of sewage treatment plants. Note: 1. For sewage pumping stations and pipelines outside the plant, the relevant provisions of this standard can be referred to. 2. The ancillary buildings and ancillary equipment of industrial sewage treatment plants with water quality similar to that of urban sewage can be referred to this standard.
Article 1.0.3 When designing ancillary buildings and ancillary equipment of sewage treatment plants, in addition to complying with the provisions of this standard, the current "Environmental Protection Law of the People's Republic of China (Trial)", "Urban Planning Regulations" and "Outdoor Drainage Design Code" (GBJ14) must also be followed.
Article 1.0.4 The scale of sewage treatment plants can be divided into six levels according to the sewage flow rate (unit is 10m/d): less than 0.5, 0.5~2, 2~5, 5~10, 10~50 and greater than 50 (the lower limit of the second to fourth levels includes this value, and the upper limit does not include this value). Sewage treatment plants are divided into two levels: primary treatment and secondary treatment (including sludge digestion and dehydration treatment). Note: Primary sewage treatment plants are referred to as primary plants, and secondary sewage treatment plants are referred to as secondary plants. Article 1.0.5 Data with a range of variation in this standard should be determined by interpolation. Engineering Construction Standard Full Text Information System
