Station d'épuration des eaux usées du village de St-Jacques - St-Jacques, Qc - Wastewater Treatment Facilities on Waymarking.com

[FR]
La Municipalité de Saint-Jacques déverse ses eaux usées à sa station d’épuration de type boues activées par un réseau d’égout séparé, c’est-à-dire que les eaux usées et les eaux de pluie sont canalisées vers deux conduites distinctes. La station à un pourcentage d’efficacité de plus de 90 %.

Le procédé de traitement des eaux usées à l’usine d’épuration passe par trois étapes principales:

Dégrillage: Étape qui consiste au retrait de matières grossières de l’eau usée.

Bassins d’aération: C’est le cœur du système. Dans ces bassins, des milliards de micro-organismes sont présents pour biodégrader la matière organique en résidus (H20, CO2, NH4, cellules biologiques, etc.). Des surpresseurs d’air permettent d’homogénéiser les eaux usées, les micro-organismes et de donner l’oxygène dissous pour la respiration de la biomasse présente.

Décantation: Traitement d’affinage. La décantation permet de séparer la biomasse (solide) de l’eau traitée. Les solides sont ensuite retirés des bassins de décantation pour être dirigés vers un filtre à bandes. Ce filtre a pour fonction de concentrer les solides par le retrait de l’eau contenue à l’intérieur de ces mêmes solides. Les solides récupérés sont ensuite enfouis dans un site d’enfouissement sanitaire.

The Municipality of Saint-Jacques discharges its wastewater at its sewage treatment plant activated by a separate sewer system, that is to say that wastewater and rainwater are channeled to two separate pipes . The station has an efficiency percentage of over 90%.

The wastewater treatment process at the purification plant goes through three main stages:

Screening: The step of removing coarse material from the wastewater.

Aeration basins: This is the heart of the system. In these basins, billions of micro-organisms are present to biodegrade organic matter into residues (H20, CO2, NH4, biological cells, etc.). Air blowers make it possible to homogenize the wastewater, the micro-organisms and to give the dissolved oxygen for the respiration of the present biomass.

Decantation: Refining treatment. Decantation separates the biomass (solid) from the treated water. The solids are then removed from the settling ponds to be directed to a band filter. This filter has the function of concentrating the solids by removing the water contained inside these same solids. The recovered solids are then buried in a sanitary landfill.

What is the capacity of the facility?: The station has an efficiency percentage of over 90%. Describe the biological treatment technology used.: Aeration basins: This is the heart of the system.

Please post at least 2 original photographs of the site. We would much rather see photos of the plant itself as opposed to the front office, but we also understand that security and site layout may limit your opportunities.
