Description
Technical field
The utility model relates to sewage treatment process and facility, in particular to a kind of small town integrated sewage disposal dress
It sets.
Background technique
The fast development of China economy and the continuous improvement of the level of urbanization, but environmental protection relatively lags behind, China
Water pollution priority control direction is the contamination control of town sewage.Activated sludge process is that current sewage farm is most widely used
Bioremediation.Activated sludge process includes the aeration tank being sequentially communicated, secondary settling tank, return-flow system, excess sludge discharge system
System and oxygen system, aeration tank, secondary settling tank and return-flow system are sequentially communicated, and aeration tank includes pond body, aerating system and Inlet and outlet water
Mouthful.Sewage is entered in aeration tank by import, and return-flow system makes in sludge reflux to aeration tank, and sewage and sludge retention exist
In aeration tank.Oxygen system to by the aerating system in aeration tank to being supplied oxygen in aeration tank, to sewage and various micropopulations
Body is continuously mixed, and is formed activated sludge, is contained the micropopulation for decomposing dirty Organic substance in water in activated sludge.It is living
Property sludge utilize activated sludge biological flocculation and precipitation, absorption and oxidation, with decompose removal sewage in organic pollutant.So
After be separated from water sludge, most of sludge flows back into aeration tank again, and activated Sludge System is then discharged in redundance.Organic matter with
The ratio between microorganism claims mud load rate (F:M), and the metabolism depth of its influence process and the settling property of sludge, mud load rate are low
A bit, the running and comparing of process is easy, and treatment effeciency is more stable, and surplus sludge volume is fewer.
It is dirty that the Chinese patent of Publication No. CN101898827A discloses a kind of activity for biological municipal sewage processing
Bricklayer's's skill, including a round pond, two annular pools and secondary settling tank composition, circle pond are located at two annular pool centers, their threes
With one heart, respectively first stage pond, second stage pond and phase III pond from inside to outside set one in circle pond and placed in the middle stir vertically
Device is mixed, the second stage pond on the outside of circle pond is tilted or is horizontally installed with propeller agitator, in outermost third
Jet stream aerator is equipped in stage pond.It is mainly characterized by the first stage stirring the returned sludge of the sewage of inflow and secondary settling tank
It mixes and mixes, horizontally recycled in second stage and push the water outlet of first stage and phegma and the mixing of third rank, in third
Stage horizontally pushes and stirs the water outlet of second stage, and triphasic water outlet is separated into clear water and precipitating work in secondary settling tank
Property sludge.The process operation is reliable, and control is flexibly and economical, and sludge settling is good, can efficiently reach removal municipal wastewater
The effect of middle organic pollutant and denitrogenation dephosphorizing.
But in actual use, the micropopulation that the returned sludge of secondary settling tank carries handles sewage,
It is less to flow back into the micropopulation contained in the sludge of aeration tank, sewage and micropopulation need to stop in aeration tank longer
Time is mixed, and micro organism quantity, which increases, reduces mud load rate, and the mixed culture time is longer, and efficiency is lower.
