Technical field
The invention belongs to sanitary sewage disposal fields, are related to a kind of high-performance bio rotated bed (BRB) domestic sewage treatment process
And processing equipment.
Background technique
Carrying out processing to life or trade effluent using microorganism is widely used processing method in sewage treatment, biology
Turntable is a kind of biofilm wastewater treatment equipment, and time-to-live generation longer microorganism, dirt can be grown on biological rotating disk
Sludge age is long, there is longer anti impulsion load ability, and high treating effect has microorganism concn in terms of technique and maintenance operation
The advantages such as high, sludge is not required to reflux, power consumption is low, operating cost is low.
The patent of invention of Patent No. US D452295S discloses a kind of biological rotating disk with aeration performance, disc point
It is three parts or four parts, coarse surface provides advantage for the growth of biomembrane, while providing sufficient oxygen for activated sludge.
Aeration quantity is adjusted by adjusting the revolving speed of turntable, to meet the oxygen demand of activated sludge and biomembrane.It is rotated in biological rotating disk
During, the air in turntable discharges to realize aeration in the form of bubble.Also, portion of air can be in cavity list
It is shifted between member, buoyancy can be increased in this way, to reduce the power consumption of equipment.It is gone on liquid level in the Cavity unit of equipment
When, the air in unit has all been discharged into waste water in the form of bubble.This aeration method, when extending air-water contact
Between, maximum possible improves oxygen transfer rate.But its there is also following deficiencies: although can be realized from be aerated, due to
Sector element aeration opening position is top, and when air inlet is sealed by the water surface, the gas in cavity is less, this allows for bringing liquid into
Air capacity is smaller;The size of bubble is not controlled effectively when aeration, and bubble is larger, and oxygen-transfer efficiency is low;Disc total surface
Product is smaller, and biomembrane bond area is greatly affected, to reduce the detergency ability of biological rotating disk.
Summary of the invention
The purpose of the present invention is to provide a kind of high-performance bio rotated bed domestic sewage treatment process and processing equipment, by
Setting splicing vibration disc is soaked in dirt in turntable after sewage enters reaction tank from the water inlet pipe in reaction tank on biological rotating disk
