Description

A kind for the treatment of process of Rubber Industrial Wastewater
Technical field
The invention belongs to field of waste water treatment, and in particular to a kind for the treatment of process of Rubber Industrial Wastewater.
Background technology
Two kinds of major items of natural rubber are caouttchouc and concentrated latex.Fresh latex is solidifying in caouttchouc process It is the main source of waste water in production process, together Gu the whey and grumeleuse of nature outflow are by the whey of ironed, creped abjection When also have granulation workshop cleaning generate effluent part.These waste water category high concentrated organic wastewaters, acidity is high, CODcr contents are high, Suspended matter is more and contains bacterium, if nearby environment, influence water quality of river, the destruction ecological balance can be polluted by not handling direct emission Deng therefore, it is vital task to administer Hao Jiao factories waste water.
Currently, domestic be mainly the following the processing of natural rubber waste water:Anaerobism-oxidation pond natural aeration method;Detest Oxygen-activated sludge mechanical forced aeration oxidation process;Oxidation pond-activated sludge mechanical forced aeration;Oxidation pond natural aeration oxygen Change method;Whey recycles UASB methods;Aquatile method etc..
1. the advantages of anaerobism-oxidation pond natural aeration method is simple in structure, but is taken up a large area, processing time is long(Single oxygen Changing the pool just needs 20 ~ 25d), the generation of anaerobism section foul smelling.Though anaerobism-oxidation pond natural aeration method saves oxidation pond, floor space It is small, but anaerobism section increases follow-up NH3- N meets(No matter other techniques such as anaerobic fermentation or UASB), stench is also generated, is located It is long to manage the time.
2. aerobic section practice aeration, though treatment effect is higher, needs the increased NH of extra reception anaerobism section3- N loads, again Lack and subsequently lack the denitrogenations links such as follow-up anoxic denitrification section, causes NH3- N poor processing effects.
3. oxidation pond-activated sludge mechanical forced aeration, takes up a large area, processing time is not long, continuous aeration efficiency It is higher but lack follow-up denitrogenation link, cause NH3- N poor processing effects.
4. oxidation pond natural aeration oxidizing process, takes up a large area, foul smelling generates when insufficient aeration.
5. in recent years, and develop the UASB methods based on whey circulation use technology, by whey circulative accumulation pollutant, High speed anaerobic bio-treated is carried out, and recycles biogas(It is mainly used for dry glue).Method removal COD efficiency is higher, is followed by Aerobic method can thoroughly realize COD, NH3- N, total phosphorus are up to standard.The disadvantage is that the culturing sludge time is longer.
6. aquatile method mainly utilizes water hyacinth, reed and algae etc. to purify the practice of Rubber Industrial Wastewater.It, which has, accounts for The disadvantage that ground area is big, processing time is grown.
The processing method that foreign countries promote and apply in this kind of wastewater treatment has:Anaerobism and facultative lagoon system;Oxidation pond system; Activated sludge process;Bio-disc system;Ground discharge etc..Wherein though anaerobism and facultative lagoon system have advantages of simple structure and simple, It takes up a large area, stench, suspended solids content is high.The efficient algae pond built on this basis(HRAP)With intermittent sand mistake Filter(ISF)Though HRAP can reduce content of organics, the adjusting and controlling growth of algae and the intermittent full-automatic behaviour of ISF The shortcomings that making, substantially increasing intractability and cost of investment, and take up a large area does not overcome yet.
Invention content
The purpose of the present invention is to provide a kind for the treatment of process of Rubber Industrial Wastewater.
The object of the present invention is achieved like this, and a kind for the treatment of process of Rubber Industrial Wastewater is made of following steps:
Step A pretreatments:Rubber Industrial Wastewater, from sump is flowed into, is set after artificial grid removes large granular impurity before sump Medicine system and its pH meter are set, sump sets submersible sewage pump;Then it is promoted to adjusting hydrolytic tank through pump, mixes water quality, and in simultaneous oxygen Partial organic substances are removed under property microbial action;
Step B removes most of organic substance and total phosphorus:The waste water that processing of step A is crossed is lifted into UASB tanks through pump, By anaerobic digestion;
Step C removes COD, BOD:The processed waste water gravity flows of step B are entered into intermediate pool(1), then with pump be promoted to BAF reaction tanks, by being aerated Aerobic Process for Treatment;
Step D removes CODcr, NH3- N, SS and total phosphorus:The processed waste water of step C is flowed into intermediate pool certainly(2), lead to It crosses pump and is promoted to active zeolite filter and biologic active carbon filtration device;
Step E:The water come out from biologic active carbon filtration device enters reuse pool, and pipe network system is promoted to through pump;
Step F:BAF, active zeolite filter, biologic active carbon filtration device backwash water enter sludge concentration tank, Chi Shang Installation folds spiral shell filter press and handles sludge, and sludge is transported outward after being promoted to the dehydration of folded spiral shell filter press by sludge pump, and part supernatant is through pump To adjusting hydrolytic tank after reflux.
Hydrolytic tank is adjusted in step A sets diving mixer.
UASB tanks are by sludge reaction area, gas-liquid-solid three-phase separator in step B(Including settling zone)With gas chamber three parts group At.
The smaller particulate filter of grain size is loaded in step C in the filter tanks BAF, by being aerated inside filter tank, filter material surface growth The biomembrane of high activity.
Intermediate pool in step C(1)Residence time be 1.3h.
Intermediate pool in step D(2)Residence time be 1h.
The residence time that pond is recycled in step E is 9.6h.
It can be used as the fertilizer of farmland or rubber forest after the sludge dewatering generated in step F.
Advantage of the present invention:
1)Economical rationality, securely and reliably;
2)Adjusting hydrolytic tank in step A enables sewage is relatively uniform to enter subsequent processing units, improves giving birth to for waste water The property changed, mitigates the processing load of follow-up sewage treatment unit;
3)Sludge Bed does not fill out carrier in UASB tanks in step B, saves cost and avoids occurring to block up match problem because of filler;
4)Three phase separator is set in UASB, can not set sludge reflux equipment.
5)BAF reaction tanks effluent quality is good in step C, and floor space is the 1/3-1/5 of general technology, and low energy consumption, operation Expense is the 1/2 of general technology, and anti impulsion load, low temperature resistant, startup is fast, automatic control, and management is very simple;
6)Two intermediate pools are set in step C and step D and play buffering, water storage protection elevator pump, inside set stirring Machine prevents sludgd deposition in basin bottom;
7)Its performance of the active zeolite used in step D approaches or is better than activated carbon in some aspects, and cost is much low It in activated carbon, can be used for filtering and the deep level of processing of water, turbidity, coloration, peculiar smell and in water in water removal can not only be removed The substances such as harmful heavy metal such as chromium, cadmium, nickel, zinc, mercury, iron ion, organic matter, phenol, three nitrogen there is absorption exchange interaction, it is right The removal rate of CODcr has higher removal ability up to 30% or more to ammonia nitrogen, phosphate anion etc. in water;
8)The biological activated carbon used in step D forms biology using the microorganism that granular active carbon is enriched with as carrier in water Film, by the biodegradation of biomembrane and the Adsorption water pollutant of activated carbon, can go remaining organic matter in water removal, Colloid, bacterium residue, microorganism etc., and can be with decolouring and deodorizing.The part that biomembrane can be adsorbed by degrading activity charcoal simultaneously Pollutant and regenerated carbon, to greatly prolong the service life of activated carbon.
9)It deals carefully with, dispose grid slag, the sludge generated in sewage disposal process, avoid secondary pollution.
