Abstract
The present invention relates to a kind of method processing sewage, a kind of method preventing Sewage Plant microorganism to run off.Carry out as follows: adding aluminium polychlorid and composite flocculation agent in cesspool, the quality proportioning of mud, aluminium polychlorid and composite flocculation agent three in cesspool is: 100000:3～9:1～7；During adding above two medicine, stir while adding, after three days, reach to observe the leakage of microorganism.The present invention is compared with prior art, aluminium polychlorid and composite flocculation agent is dosed in cesspool, improve stability and the adhesive force of activated sludge, reach oxidation ditch activated sludge flocculation is realized micro-life solidifications on mud such as tired branch worm, reach to eliminate second pond and discharge micro-raw special leakages such as tired branch worm in a large number.
Description
Technical field
The present invention relates to a kind of method processing sewage, a kind of method preventing Sewage Plant microorganism to run off.
Background technology
During sewage treatment industry activated sludge process is run, owing to a lot of Sewage Plant are to design by sanitary sewage disposal, but have part of contaminated water factory contain about 80% industrial wastewater and water quality the most unstable, it sometimes appear that abnormal conditions, making tired branch worm with the agglomerating loss of secondary clarifier effluent, loss cenobium is white flock body and has certain viscosity, is very easy to cause the follow-up equipment such as filter tank, reverse osmosis to block and is difficult to process, making maintenance cost significantly rise, wastewater treatment efficiency reduces.Emerged in operation this it may be the case that be mixed into caused by noxious substance in Industry Waste water temperature over-high and sewage.
Summary of the invention
It is an object of the invention to provide a kind of method preventing Sewage Plant microorganism to run off.
The present invention adopts the following technical scheme that
A kind of method preventing Sewage Plant microorganism to run off, is carried out as follows:
A, adding aluminium polychlorid and composite flocculation agent in cesspool, the quality proportioning of mud, aluminium polychlorid and composite flocculation agent three in cesspool is: 100000:3～9:1～7；
B, adding during above two medicine, stirring while adding, after three days, reach to observe the leakage of microorganism.
The present invention is compared with prior art, aluminium polychlorid and composite flocculation agent is dosed in cesspool, improve stability and the adhesive force of activated sludge, reach oxidation ditch activated sludge flocculation is realized micro-life solidifications on mud such as tired branch worm, reach to eliminate second pond and discharge micro-raw special leakages such as tired branch worm in a large number.
The preferred version of the present invention is:
In step A, the quality proportioning of mud, aluminium polychlorid and composite flocculation agent three is: 100000:9:1.
Composite flocculation agent is made up of chitosan, cation high molecular sodium salt, ferric metasilicate aluminium salt, and aforesaid quality proportioning is: 1:2:3.
In step A, the quality proportioning of mud, aluminium polychlorid and composite flocculation agent three is: 100000:8:2.
In step A, the quality proportioning of mud, aluminium polychlorid and composite flocculation agent three is: 100000:7:3.
In step A, the quality proportioning of mud, aluminium polychlorid and composite flocculation agent three is: 100000:6:5.
In step A, the quality proportioning of mud, aluminium polychlorid and composite flocculation agent three is: 100000:5:5.
In step A, the quality proportioning of mud, aluminium polychlorid and composite flocculation agent three is: 100000:4:6.
In step A, the quality proportioning of mud, aluminium polychlorid and composite flocculation agent three is: 100000:3:7.
Aluminium polychlorid and composite flocculation agent mark are dosed.
Detailed description of the invention
Below in conjunction with the embodiment detailed description present invention:
Embodiment:
By the collection of oxidation ditch activated sludge is sampled, it is dispensed in the container that not isodose is bigger, carry out the interpolation stirring of medicine, then look at the floating out stickiness white biology sheet with microorganisms such as tired branch worms of supernatant how many, thus obtain the effect under different agents adding proportion.
Composite flocculation agent is made up of chitosan, cation high molecular sodium salt, ferric metasilicate, aluminium salt, and the quality proportioning of aforementioned three is: 1:2:3.
In July, 2013, Fengnan Li Yuan sewage company limited finds that a large amount of white plates stickies leakages occurs in second pond, containing microorganisms such as a large amount of tired branch worms in assay finds white plates, thereby result in oxidation ditch microorganism to reduce, wastewater treatment efficiency reduces, and filter tank is resulted in blockage by the stickies outflowed with water, make to block on the depth-averaged model facility reverse osmosis membrane of downstream water demand Hu Guofeng steel mill, Guo Feng steel mill water treatment capacity is caused to decline, and changed part reverse osmosis membrane, it is properly functioning that impact produces, after analyzing this thing reason of generation, one is by taking specific aim technological measure to reduce its generation again, two is by adding this measure of flocculated drug, microorganism losing issue is prevented rapidly in three days, achieve the stable operation up to standard of water treatment, decrease economic loss.
It is by non-structural filamentous bacteria raised growth that the microorganisms such as tired branch worm are run off, it is formed without flco or the noxious substance short time enters and makes microorganism lose the conditions of existence in mud, the microorganisms such as tired branch worm are caused no longer to depend on mud growth, but separate and diffuse to form microbic mass, and it is owing to very gently and having certain flow velocity in sewage disposal, discharges in a large number so being mixed in water, by adding flocculant, reach the flocculation solidification on mud of the tired branch worm, strengthen settleability, prevent the loss of microorganism.
