Description
Technical fieldThe utility model relates to municipal effluent and Industrial Wastewater Treatment device, particularly a kind of many lattice vertical current granule sludge cultivating container.
Background technologyThe main applying biological treatment process of municipal effluent and Industrial Wastewater Treatment.Activated sludge process is one of current biological method for treating waste water that generally adopts, and its great advantage is that active sludge microorganism is distributed in the sewage with the form that suspends, and can fully contact with sewage and carry out bio-oxidation.In biological treatment system, the height of processing efficiency is by the characteristic decision of active sludge microorganism, and the big more treatment efficiency of living weight is high more.Activated sludge process is because living weight is lower, and treatment efficiency is also not high enough, brings certain difficulty to prevention and cure of pollution work.Microbial population is on the low side to be another shortcoming of activated sludge process, and the removal that this will be unfavorable for nitrogen in the sewage, phosphor contaminant is unfavorable for the qualified discharge of WWT.
Biomembrance process has bigger living weight, and the 5-20 that its unit volume living weight is an active sludge does not doubly run off because of water body because of microbial film again.Realized separating of biosolids residence time SRT and hydraulic detention time HRT, greatly prolonged the generation time of allowing of mikrobe, therefore population quantity of mikrobe and food chain length also greatly increase.As microbial film being grafted in the activated sludge process to remedy the deficiency of activated sludge process, just the process of biological sewage treatment can be accelerated greatly.
The Sludge System increase living weight that appears as of granule sludge has been raised new page, but the breeding condition of granule sludge is still among exploring.The utility model from the growth condition of biological floe, be developed into many lattice vertical current granule sludge cultivating container, in the hope of with the pond type of standard comparatively, cultivate granule sludge.Let granule sludge play a role as early as possible at sewage treatment area.
The utility model contentThe technical problem that the utility model will solve is to provide many lattice vertical current granule sludge cultivating container that a kind of biotic population quantity is big, the bio-oxidation treatment efficiency is high, construction costs is low, working cost is low.
It is following that the utility model solves the problems of the technologies described above the technical scheme of taking: a kind of many lattice vertical current granule sludge cultivating container comprises the pond body, sewage water inlet pipe; Inlet flume; Rising pipe, effluent trough, shore pipe; It is characterized in that: be provided with severally in the body of pond, the pond body is divided into several placed in-line spaces vertical flow deflector; First vertical flow deflector bottom of every pair of vertical flow deflector is provided with spacing, the airtight body bottom, pond that is fixed on, second vertical flow deflector bottom with pond body bottom from feed-water end to water side, and the space is divided into current down going channel and current data feedback channel; Horizontal mode sets up the netted dividing plate of several layers in the current data feedback channel; Blast main and aerator are equipped with in current data feedback channel bottom, and blast main is connected with blast main with aerator.
Workflow of the utility model and mechanism are roughly following: blast main and the aerator that be equipped with current data feedback channel bottom, and in order to form aerobic environment at the upward flow passage.Sewage is got in the rectangle form pool through inlet flume by sewage water inlet pipe; Sequential flow is crossed current down going channel and current data feedback channel; And, flow through each space of cultivating container with continuous downward, the reciprocating and turning-back that makes progress of the form of vertical current, progressively accomplish the cultivation maturing process of biofloculation and granule sludge.In biofloculation and granule sludge cultivation slaking, sewage also is purified in the metabolic activity of mikrobe.Sewage after the purification flows into two settling tanks via rising pipe, carries out the precipitate and separate of mud.Mud return line and two sludge from sedimentation tank pipes join, and reflux in order to carry out mud.
The netted lattice plate of multilayer that level is installed in the current data feedback channel; For mikrobe provides good apposition growth environment; From mikrobe particularly the thread fungus intensive seek connections with instinct; Have microbial film to adhere on it on the web plate very soon, this not only becomes the defence line of one degradable organic pollutant, and the microbial film that under current scour, peels off also will become the flocculation center of biological floe and progressively grow into granule sludge.Multi-layered net plate not only can be combed stream, makes velocity flow profile more even, and the current behind the web plate can form many whirlpool bodies; Under the whirlpool body promoted, biological floe can very fast flocculation be grown up into granule sludge.The upstream that netted lattice plate can also make aerator produce strengthens current turbulence kinetic energy.The enhancing of shearing force and turbulence energy not only helps flco and grows into granule sludge, has also reduced the resistance that influences mass transfer, outer mass transfer and inner transmission matter resistance is reduced synchronously, and then the speed of biochemical reaction is accelerated greatly, has promoted the purification of water quality of sewage.
The utility model from the growth condition of biological floe, succeed in developing many lattice vertical current granule sludge cultivating container, in the hope of with the pond type of standard comparatively, cultivate granule sludge.The utility model beneficial effect is:
1, many lattice vertical current granule sludge cultivating container extremely is beneficial to the removal of nitrogen in the sewage, phosphor contaminant, can make the bio-oxidation effect improve 5 ~ 10%, reduces construction costs about 5%, reduces working cost about 10%.
2, the generation of granule sludge improves the sedimentation function of active sludge greatly, can follow-up two settling tank hydraulic surface loadings be risen to more than the 2m/h from 1m/h.Saving this construction costs reaches about 30%.
