Description
Technical field
The utility model relates to field of waste water treatment, particularly relates to a kind of high-concentration industrial-water and detests foster treatment system.
Background technology
In the ultra-high concentration organic wastewater that industry produces, acid, bases is numerous, often has strong acid or strong basicity.The one, aerobism harm: due to biological degradation, high concentrated organic wastewater can make even anaerobism of receiving water body anoxic, most aquatic organisms are by death, thus generation stench worsens water quality and environment.The 2nd, sense organ contact scar: high concentrated organic wastewater not only makes water body lose use value, more has a strong impact near the people's of water body orthobiosis.The 3rd, cause toxicity hazard: in ultra-high concentration organic wastewater, contain a large amount of toxic organic compounds, can in the physical environment such as water body, soil, constantly accumulate, store, finally enter human body, be detrimental to health.
Utility model content
The purpose of this utility model is to solve prior art problem, and a kind for the treatment of system for high-concentration industrial-water is provided, and uses " improvement acidication system+improvement UASB system " to form an efficient anaerobic treatment system, for BOD
5, the higher trade effluent of Pollutant levels such as CODcr, have very high anti-load impact ability and processing efficiency.
The utility model adopts following technical scheme: a kind of high-concentration industrial-water is detested foster treatment system, comprise hydrolysis acidification pool and USAB system, in described hydrolysis acidification pool, be divided into four lattice, each lattice is provided with traverse baffle, described USAB system comprises sludge reaction district, triphase separator and air chamber, and described hydrolysis acidification pool links together by return line and USAB system.
In technique scheme, in described hydrolysis acidification pool, from being divided into four lattice as the mouth of a river to water outlet, every lattice inside is divided into upper reaches compartment and dirty compartment, and upper reaches compartment is got 4:1 with the ratio of the width of dirty compartment.
In technique scheme, described upper reaches compartment is 1:3 along the long-width ratio of current working direction, and the ratio of width to height is 1:3.
In technique scheme, in first three lattice in described hydrolysis acidification pool, be respectively arranged with clear water agitator and elasticity stopping composition, in the 4th lattice, be provided with sludge reflux pump.
In technique scheme, the knuckle of described traverse baffle is got 45 °, and traverse baffle stretches into the middle part of upstream room.
In technique scheme, described triphase separator upper end arranges return line and is connected with USAB system top.
In technique scheme, the air chamber of described USAB system lower end arranges water distributor, and water distributor is connected with the return line on USAB system top by pipeline.
The utility model has the advantage of: use " improvement acidication system+improvement UASB system " to form an efficient anaerobic treatment system, for the higher trade effluent of the Pollutant levels such as BOD5, CODcr, CODcr influent concentration has very high anti-load impact ability and processing efficiency, as can be reached 15000-30000mg/l.
First high-concentration industrial-water enters improvement hydrolysis acidification pool macromolecular substance is resolved into small-molecule substance, improves biodegradability, then enters improvement UASB pond, further decomposing organic matter, and produce methane gas.The pollutent of this anaerobic system in can better degrading high concentration waste water, system can reach more than 90% the clearance of COD.
Accompanying drawing explanation
Fig. 1 is system principle schematic diagram of the present utility model.
Embodiment
Now by reference to the accompanying drawings the utility model is further illustrated.
As shown in Figure 1, the hydrolysis acidification pool hydraulic detention time HRT in the utility model is 12-16h, compared with traditional hydrolysis acidification pool, has reduced HRT, has reduced pond appearance, has saved cost.General point four lattice in pond, every lattice inside is divided into upper reaches compartment and dirty compartment according to the flow direction of current, and upper reaches compartment is got 4:1 with the ratio of the width of dirty compartment, makes reactor hydraulic flow state in more efficient in HRT; Reactor upstream room is 1:3 along the long-width ratio of current working direction, the wide high 1:3 that adopts.In hydrolysis acidification pool, set up the soft-filler that 1.5-2m is high and add agitator, utilize original volume gain biological total amount, having accelerated separating of mud and bubble, thereby having reduced the loss of mud; In hydrolysis acidification pool, the knuckle of traverse baffle is got 45 °, makes flap stretch into the middle part of upstream room, is beneficial to water distribution uniformity, prevents channel.Increase the volume of the first compartment, to effectively hold back into the SS in water simultaneously suitably; Hydrolysis acidification pool sludge reflux, point two portions reflux, and the one, reactor self refluxes, and last lattice of hydrolysis acidification pool adopt pump groove, and perforated pipe spoil disposal, draws back stream by pump, prevents sludge loss, adopts 100% backflow best results.The 2nd, from the backflow of improvement UASB system, can effectively solve reactor front end compartment because of problems such as the pH value reductions that produces more VFA VFA and cause.Practical experience shows, in the time processing some containing protein waste water, this measure can effectively suppress hyphomycetic growth, the hazardous and noxious substances in dilution water inlet, thus further improve treatment effect.
UASB system in the utility model is made up of sludge reaction district, triphase separator (comprising settling region) and air chamber three parts.Digital model calculating by us to UASB system and engineering experience are summed up and have been designed a set of module with optimum handling effect, and it is 100m that each module can be processed the water yield
3/ d, the ratio that length and width are high is 2:1:2, the engineering of the different water yields is adopted to the mode of splicing in parallel, can reach best treatment effect, compared with traditional UASB internal reflux, UASB sludge reflux is to best results before hydrolysis acidification pool, can effectively solve hydrolysis acidification pool front end compartment because of problems such as the pH value reductions that produces more VFA VFA and cause; UASB sludge reflux adopts takes over to go out from UASB top pipe backflow as shown in above schema from bottom, settling region, triple effect separator upper end, and on return line, adding water sprayer, backflow can effectively improve hydrolysis section processing efficiency, refluxes and utilizes siphon principle simultaneously, without power, save running cost; When UASB commissioning test, can add granulated active carbon, provide carrier to anaerobion, can reduce the sludge quantity that early stage, culturing sludge was thrown in, when culture sludge, in reactor, middle and lower part sludge concentration can reach 40-60mg/l.
Disclosed all features in this specification sheets, except mutually exclusive feature, all can combine by any way.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
