Abstract

The invention relates to a microbial wastewater treatment system, comprising a filter tank, a bioreactor, a settling tank and a disinfecting tank which are connected in sequence via a pipeline. A grille is arranged in the filter tank; the bioreactor is filled with a biofiller; the filter tank is provided with a water inlet; the disinfecting tank is provided with a water outlet; the wastewater treatment system also comprises a drug feeder including a trace nutrient storage tank and a drug feeding pipe; an outlet of the drug feeding pipe is extended to the inner lower portion of the bioreactor and is not in contact with the bottom of the bioreactor; the wall of the part, extended into the bioreactor, of the drug feeding pipe is provided with drug release holes. The microbial wastewater treatment system can promote the growth of facultative bacteria in a microbial system and increase degrading efficiency of organic pollutants, can effectively improve the ecological environment of wastewater, control odor and improve water quality, enables water to flow out more stably, and can decrease water content of sludge and reduce the amount of sludge to be treated, thereby saving treatment costand saving power.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment system. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, the amount of sewage discharge has also increased dramatically. Sewage is a general term for domestic sewage, industrial sewage, rural sewage and polluted rainwater. At present, the biological contact oxidation method is the most commonly used method to treat domestic sewage. It is widely used in sewage treatment systems in various industries because of its high efficiency, energy saving, small footprint, impact load resistance, and convenient operation and management. The biological contact oxidation method belongs to the submerged biofilm method. The sewage treatment tank is filled with fillers, and then the oxygenated sewage is injected to submerge all the fillers. When the sewage flows through the fillers at a certain ...
