Abstract
The invention relates to a method for sewage treatment and particularly relates to a method for preventing loss of microbes of a sewage plant. The method is performed according to the following steps: adding polyaluminum chloride and a composite flocculant into a sewage tank, wherein the mass ratio of sludge to polyaluminum chloride to the composite flocculant in the sewage tank is 100000: (3-9): (1-7), and in the process of adding the two medicines, the medicines are added while being stirred; and observing the loss phenomenon of the microbes after three days. Compared with the prior art, by adopting the method provided by the invention, polyaluminum chloride and the composite flocculant are added into the sewage tank, so that the stability and adhesion of the activated sludge are improved, flocculation of the sludge in an oxidation ditch is achieved, solidification of epistylis and other microbes on the sludge is realized, and the loss phenomenon of the epistylis and other microbes caused by great discharge from a secondary sedimentation tank is eliminated.
Description
Technical field
the present invention relates to a kind of method of disposing of sewage, particularly a kind of method preventing Sewage Plant microorganism to run off.
Background technology
during sewage treatment industry activated sludge process is run, because a lot of Sewage Plant designs by sanitary sewage disposal, but there is part of contaminated water factory to contain the trade effluent of about 80% and water quality is very unstable, there are abnormal conditions sometimes, make 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, maintenance cost is significantly risen, and wastewater treatment efficiency reduces.This situation of emerged in operation may be mixed into caused by toxic substance in Industry Waste water temperature over-high and sewage.
Summary of the invention
the object of the present invention is to provide a kind of method preventing Sewage Plant microorganism to run off.
the present invention adopts following technical scheme:
prevent the method that Sewage Plant microorganism is run off, carry out as follows:
a, in sewage lagoon, add polymerize aluminum chloride and composite flocculation agent, the quality proportioning of the mud in sewage lagoon, polymerize aluminum chloride and composite flocculation agent three is: 100000:3 ~ 9:1 ~ 7;
b, in the process of adding above-mentioned two kinds of medicines, to stir while adding, reach after three days and observe the leakage of microorganism.
the present invention compared with prior art, polymerize aluminum chloride and composite flocculation agent is dosed in sewage lagoon, improve stability and the sticking power of active sludge, reach and the solidifications of micro-life on mud such as tired branch worm are realized to oxidation ditch activated sludge flocculation, reach elimination second pond and discharge micro-raw special leakages such as tired branch worm in a large number.
preferred version of the present invention is:
in steps A, the quality proportioning of mud, polymerize aluminum chloride 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 steps A, the quality proportioning of mud, polymerize aluminum chloride and composite flocculation agent three is: 100000:8:2.
in steps A, the quality proportioning of mud, polymerize aluminum chloride and composite flocculation agent three is: 100000:7:3.
in steps A, the quality proportioning of mud, polymerize aluminum chloride and composite flocculation agent three is: 100000:6:5.
in steps A, the quality proportioning of mud, polymerize aluminum chloride and composite flocculation agent three is: 100000:5:5.
in steps A, the quality proportioning of mud, polymerize aluminum chloride and composite flocculation agent three is: 100000:4:6.
in steps A, the quality proportioning of mud, polymerize aluminum chloride and composite flocculation agent three is: 100000:3:7.
polymerize aluminum chloride and composite flocculation agent divide to be dosed for several times.
Embodiment
below in conjunction with embodiment in detail the present invention is described in detail:
embodiment:
by sampling the collection of oxidation ditch activated sludge, be dispensed in the larger container of not isodose, the interpolation carrying out medicine is stirred, and then checks that the floating biological sheet of stickiness white out with microorganisms such as tired branch worms of supernatant liquor is how many, thus obtains the effect under different agents adding proportion.
composite flocculation agent is by chitosan, cation high molecular sodium salt, ferric metasilicate, and aluminium salt is formed, 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 leakage appears in second pond, find in white plates containing microorganisms such as a large amount of tired branch worms through assay, oxidation ditch microorganism is caused to reduce thus, wastewater treatment efficiency reduces, and the stickies outflowed with water results in blockage to filter tank, make the depth-averaged model facility reverse osmosis membrane of downstream water demand Hu Guofeng steel mill blocks, Guo Feng steel mill water treatment capacity is caused to decline, and changed part reverse osmosis membrane, the normal operation that impact is produced, after analyzing this thing reason of generation, one is the generation again by taking specific aim technological measure to reduce it, two is by adding this measure of flocculated drug, microorganism losing issue is prevented rapidly in three days, achieve the steady running up to standard of water conditioning, decrease financial loss.
it is by non-structural thread fungus raised growth that the microorganisms such as tired branch worm are run off, not forming flco or toxic substance short period of time enters and makes microorganism lose the life condition in mud, the microorganisms such as tired branch worm are caused no longer to depend on mud growth, but be separated and diffuse to form microbic mass, and it is due to very light and have certain flow velocity in sewage disposal, discharges in a large number so be mixed in water, by adding flocculation agent, reach the flocculation solidification of tired branch worm on mud, strengthen settleability, prevent the loss of microorganism.
