The direct discharge process of domestic sewage treatment equipment on the construction site refers to the direct discharge of domestic sewage generated by the construction site into the municipal sewage pipe network without any treatment. This process is suitable for small construction sites or short-term construction projects, and has the advantage of low cost and easy operation.
However, if the site is located far from the municipal sewer network, or if the site has a large amount of wastewater, other processes will need to be used for treatment. Commonly used processes include activated sludge method, biological contact oxidation method, A2O method, etc.
When the activated sludge method is adopted, it is necessary to set up facilities such as regulating tanks and aeration tanks to remove pollutants such as organic matter and suspended solids in wastewater through processes such as aeration, sedimentation, and sludge reflux. When the biological contact oxidation method is adopted, it is necessary to set up a biological contact oxidation pond to convert the organic matter in the wastewater into harmless substances through the action of microorganisms. When the A2O method is adopted, facilities such as anaerobic ponds, anoxic ponds and aerobic ponds need to be set up to remove pollutants such as organic matter, nitrogen and phosphorus from wastewater through a series of biological reaction processes.
In short, the direct discharge process of domestic sewage treatment equipment on the construction site is a simple and low-cost process, but it is necessary to consider the actual situation of the construction site and environmental factors to select the appropriate process for treatment.
