Foreword

HY/T 168 "Code for Design of Seawater Post-treatment for Large-scale Domestic Use" is divided into four parts. ---Part 1.Activated sludge method; ---Part 2.Contact oxidation method; ---Part 3.Membrane Bioreactor Method; ---Part 4.Ecological pond method. This part is part 2 of HY/T 168. This section was drafted in accordance with the rules given in GB/T 1.1-2009. This part was proposed by the Tianjin Seawater Desalination and Comprehensive Utilization Research Institute of the State Oceanic Administration. This part is under the jurisdiction of the National Marine Standardization Technical Committee (SAC/TC283). This section was drafted by. Tianjin Seawater Desalination and Comprehensive Utilization Research Institute of the State Oceanic Administration, Qingdao Urban Water Conservation Office. The main drafters of this section. Zhang Yushan, Wang Jing, Zhang Guohui, Jiang Tianxiang, Cheng Yu, Ren Huafeng, Shanke. Design code for seawater post-treatment for large domestic use Part 2.Contact oxidation method

1 Scope

This part of HY/T 168 specifies the terminology, general regulations, and oxygen exposure in the treatment of sewage systems containing large amounts of domestic seawater by the contact oxidation method. Chemical tank process design, sedimentation tank process design, etc. This section is applicable to the design of sewage treatment projects containing large domestic seawater by contact oxidation.

3 Terms and definitions

The following terms and definitions defined in GB 50014 apply to this document. 3.1 Contact oxidation Under aerobic conditions, the sewage is in extensive contact with the biofilm on the surface of the filler to purify the sewage. 3.2 Plastic media Used to provide a carrier for the growth of microorganisms, with hard, soft and semi-soft fillers. [GB 50014-2006, definition 2.1.81] 3.3 Slag The melt floating on the surface of the liquid metal substance generated in the pyrometallurgical process is composed of oxides (silica, alumina, oxidation Calcium, magnesium oxide) mainly, but also contains sulfide with a small amount of metal.

4 General rules

4.1 Before the sewage enters the contact oxidation system, it should be treated with grille, grit, and first sedimentation and set up a salinity adjustment tank. 4.2 The contact oxidation system adopts a two-stage type, that is, the first contact oxidation section---the first stage sedimentation tank, and the second contact oxidation section---the second stage sedimentation tank. The lake. 4.3 Disinfection facilities for water outlet should be set up. 4.4 The overall layout design and disinfection process of the post-treatment project of the large-scale domestic seawater contact oxidation method shall be implemented in accordance with the regulations of GB 50014. 4.5 Sewage treatment structures such as grids, sedimentation tanks, and contact oxidation tanks should fully consider the corrosivity of seawater, and their structural design and material selection should be based on
