Chapter I preparation of the description and project overview
The construction organization design is based on the sewage treatment plant preparation office "sewage treatment plant project construction bidding instruments" and the company designed engineering construction drawings, in the project site on the basis of a preliminary survey, combined with the relevant technical specifications, standards and the company's experience in the construction of similar projects in the past and practices compiled as a bidding technology documents Provided to the construction unit.
The preparation of this construction organization design includes the construction organization and deployment of the sewage treatment plant, schedule, the main resource input plan, technology, quality, safety assurance measures, process piping installation, equipment installation, electrical installation, installation and commissioning of weak electricity construction procedures, the main methods.
Because of the compilation of time in a hurry, the process, equipment, technical information is still missing, drawing design is not very detailed and perfect, once the project won the bid, we will be in the drawings on the basis of the review, the design of this design to further enrich the formation of the official construction organization design.
Section I of the basic situation of the project
The sewage treatment plant construction project is the project.
Design unit:
Supervision unit:
Engineering address:
The sewage treatment plant treatment process for the membrane method of the central island oxidation ditch process, the plant covers a total area of square meters, of which: the building covers an area of square meters, square meters of green space, road square and other areas of square meters. Engineering construction drawings, geological surveys have been completed. Construction water, electricity, construction drainage, construction sites, roads are basically equipped with the conditions for the start of work.
Section II Engineering Design Overview
The wastewater treatment plant to deal with the sewage % is industrial sewage, % is domestic sewage. For its water quality characteristics, the design of the membrane method used in the center of the island oxidation ditch process. The scope of the construction plan design for the sewage treatment plant within the walls of the sewage treatment and sludge treatment and related ancillary facilities.
Wastewater treatment plant design scale m3/d, influent water quality: PH =, COD = mg/1, BOD5 = mg/1; SS = mg/1; NH3-N = mg/1; effluent water quality PH =, COD ≤ mg/1, BOD5 ≤ mg/1, NH3-N ≤ mg/1.
The wastewater treatment process flow is shown in Appendix XI:
The membrane center island oxidation ditch process. Membrane Method Center Island Oxidation Ditch Process Flow Block Diagram". The main sections of the installation project include pretreatment section (coarse grating, sewage lifting pump room, fine grating, bell-type sand sedimentation tank, etc.), membrane center island oxidation ditch, contact filter, blower room, mud treatment section (sludge thickening tank, sludge dewatering room, etc.) and ancillary facilities such as the comprehensive building, mechanical repair room. The installation work involves the installation and commissioning of process equipment, process piping, water supply and drainage, strong electricity, instrumentation and automatic control, and other divisions.
Section III construction technical standards, norms
For the content of the project construction, the installation of the project should comply with the main construction plan design and the following technical standards, norms:
1. Enterprise standards, regulations
