Abstract

The invention relates to the technical field of advanced sewage treatment, and discloses an expressway service area sewage treatment device which is characterized in that a sedimentation tank is connected with a water inlet pipe; the regulating tank is connected with the sedimentation tank through a pipeline; the anoxic tank is connected with the regulating tank through a pipeline; an aerobic tank; and the membrane bioreactor is respectively connected with the bottoms of the anoxic tank and the aerobic tank through water passing holes. An integrated membrane bioreactor treatment process with a special efficient microorganism cultivation function is adopted, the removal rate of organic matters and total nitrogen is increased, the amount of residual sludge is reduced, and the device has good impact load resistance and can adapt to changes of water quantity, water quality and temperature; the method is especially suitable for deep purification treatment of sewage in expressway service areas with large fluctuation of water quality and water quantity, can meet the water quality indexes of recycled water in multiple occasions, and realizes the idea of green service areas.

Description

technical field [0001] The invention relates to the technical field of advanced sewage treatment, in particular to a sewage treatment device and method for expressway service areas. Background technique [0002] The sewage in the expressway service area mainly comes from the domestic bath water of the employees in the service area, the oily sewage from the auto repair workshop, and the sewage from public toilets. The characteristics of sewage in expressway service areas are: the concentration of pollutants is slightly larger than that of domestic sewage in residential areas, the water quality is unstable, and the content of COD, ammonia nitrogen, phosphorus, chromaticity, and oil pollution is high at the peak of pollution. The amount of water is highly volatile and may vary hourly, daily, day and night. At present, the expressway service area basically adopts the traditional sewage treatment technology, and the traditional sewage treatment technology generally adopts the bi...
