Product Description

Expressway service area sewage has the following characteristics:

The water volume fluctuates greatly, and the amount of sewage is affected by the traffic flow. The amount of sewage in the high-speed service area is usually characterized by large, short-lived and intermittent;

The biodegradability is better, but the concentration of pollutants such as organic matter and ammonia nitrogen is higher;

The sewage is uneven, and the treatment difficulty is higher than that of typical domestic sewage.

The selection of sewage treatment process in the service area directly affects the sewage treatment effect and availability. The selection of process needs to be considered systematically and comprehensively. The natural environment, climate characteristics, land availability, effluent quality requirements and other factors of the service area should be considered. For example, in the northern area, biological treatment process or biological-ecological combined process can be selected to ensure the sewage treatment effect under low temperature conditions in winter; developed areas can give priority to MBR process and other underdeveloped areas can give priority to ecological treatment technology.
