Fig. 2 is seen according to the system composition designed by technological process

Present treatment system is made up of three parts, it may be assumed that main frame, ASBR, SBR.

Main frame is the core processing equipment of present treatment system.It is controlled subsystem, UV/TiO by PLC program again₂+O₃+H₂O₂ Processing subsystem, gas active charcoal adsorption subsystem, barrier film electrodialysis subsystem, panel automatically controlled subsystem five collaborative with electrolysis System is highly integrateable in all steel cabinet of size 480 × 480 × 1500mm, forms a floor mounted equipment, its Inner part is the configuration of floor shape, liquid waste processing capacity 20L/ time.

Process main frame and have employed state-of-the-art low-voltage low frequency height electric current " alternation " pulse electricity in current water technology Water Treatment technology is main body, with three kinds of electrolysis modes and the ozone on three series connection periods in same electrolysis bath to waste liquid Carry out the most collaborative process, then go here and there with UV/TiO₂+O₃+H₂O₂Link, removed the CODcr in waste liquid in 6 hours 80%～90%, by total Cr⁶⁺It is removed to less than primary pollutant the highest permission discharge standard (≤0.5mg/L)；Phenyl amines is degraded It is removed to less than three grades of emission standards (≤5mg/L).Whole electrolytic process uses more advanced PLC program to control and realize The automatization of electrolytic treatment phase.In electrolytic process, escaping gas is by carrying out absorption in negative pressure-pumping to activated carbon.At electrolysis Water after reason is clarified, and after entering barrier film electrodialysis system desalination, is finally completed the process task of main frame.Whole main frame is exactly One by the water technology cell height organic integration of several current advanced persons, efficient, practical integration apparatus, its appearance Fill up the blank of the integration apparatus processing ultrahigh concentration, high toxicity, high salinity waste water both at home and abroad at normal temperatures and pressures.

ASBR is the english abbreviation of " anaerobic active sludge bioreactor ", and it is current high concentration organic sewage Most advanced and the most easily-controllable form of anaerobic degradation.

Although main frame is by the contaminant removal in waste water 80%～90%, but, belong to superelevation owing to so-and-so chemically examines waste liquid The special waste liquid of concentration, CODcr reaches as high as 300 000mg/L, even if therefore obtaining the efficient process of main frame, it is remaining CODcr still has 20 000～60000mg/L, and this numerical value is still that outside Now Domestic that general water processes the upper of the former water in concept Limit value, it is therefore necessary to continue with.The organic carbochain of Long carbon chain or the fragrance same clan is shortened owing to electrolysis processes, make Residual organic substances is quite suitable for biological treatment, and comparatively speaking, it is organic that the high-level oxidation technology in main frame processes difficult degradation Thing effect is obvious, processes simple organic then effect the most notable.Therefore subsequent treatment is designed as biological treatment.

ASBR reactor is easily for 200L, the closed reactor of (500 × 500 × 1500mm), employing water pump circulation Stirring (or mechanical agitation) promotes water and anaerobic activated sludge full and uniform mixing therein to ensure that anaerobic bacteria is to pollutant Efficient-decomposition.Waste liquid (20L, CODcr=20 000～60 000mg/L) after electrolysis processes is the most natural after entering ASBR Diluting 10 times, become 2 000～6 000mg/L, its CODcr clearance was designed as 40% (deliberately allowing some leeway), then at ASBR Water outlet CODcr after reason is designed as 1200～3 600mg/L.

SBR is the english abbreviation of " batch type aerobic activated sludge process or reactor ", and capacity is 100L, (500 × 500 × 700mm), blast aeration form is used to provide the oxygen needed for biochemical degradation Organic substance to aerobic activated sludge antibacterial.Aerobic Under the biochemical action of activated sludge antibacterial, useless Organic substance in water obtains degraded further.Designing its CODcr clearance is 50% (consideration of allowing some leeway takes lower value design).After discharging water (discharge capacity 20L every day) entrance SBR from ASBR, naturally it is diluted 5 Times, then its dilution after CODcr from ASBR discharge time 1 200～3 600mg/L become 240～720mg/L, enter one through it Step degraded so that it is water outlet CODcr becomes 170～300mg/L.Under better mode of operation, its CODcr is much smaller than row Enter three grades of discharge standards (CODcr≤1 000mg/L, total Cr≤1.5mg/L, Cr that sewer should reach⁶⁺≤ 0.5mg/L, aniline Class≤5mg/L), therefore can directly drain into sewer.

ASBR Yu SBR leaves bigger leeway the most in the design on capacity or on degradation capability, but considers If to round-the-clock continuous run into, they internal inevitable accumulation producing CODcr, the CODcr i.e. processed increases in time Greatly, it is therefore necessary to have leeway.

The equipment of system is mainly made up of, such as Fig. 3 main frame (including trunk and aid system), ASBR, SBR.

Specifically, a kind of laboratory waste liquor treatment equipment, including main frame, ASBR device and SBR device；Described main frame bag Include electric apparatus room and ozonator room 2, electrolysis transformator 3, electrolysis unit 4, pump chamber 6, water tank 7, raw water box 12, settling tank 13 and Clear water tanks 14；Described electric apparatus room and ozonator room 2, electrolysis unit 4, pump chamber 6 and water tank 7 arrange from top to bottom, Qi Zhong electricity Solving device 4 and be provided with an electrolysis bath 5, described electrolysis unit 4 is connected with pump chamber 6 and electrolysis transformator 3 respectively, described water tank 7 Rear side be provided with raw water box 12, settling tank 13 and clear water tanks 14.

The feature of this structure be all subsystems be floor state configuration, be followed successively by electric cabinet, electric apparatus room, electricity from top to bottom Solve transformator and electrolysis bath, pump chamber, water tank group.The advantage of this structure be configuration compact, and floor space and take up space little.

Main frame is the nucleus equipment of present treatment system, and it has been internally integrated the outer unique " UV/TiO of Present Domestic₂+O₃ +H₂O₂Collaborative alternating impulse electrochemical water treatment technology " and PLC program control technology, it is achieved that intelligentized control method.

Control mode: ozone adds three sections of alternating impulse electrolysis PLC program and controls remainder plate face electrically by keying System

This main frame have employed alternating impulse electrolysis power supply, and this power supply can overcome other unvanquishable electricity of power supply up hill and dale The polarization of pole and passivation phenomenon, thereby ensure that the high efficiency of electrochemical treatment process.On this basis, again in electrolysis bath Introduce O₃Cause ozone strong oxidizing effect collaborative with coupling of electrolysis Strong oxdiative/cohesion, more enhance treatment effeciency.Close In addition to this utility model, report is had no the most both at home and abroad in ozone cooperative alternating pulse chemical treatment method.Relay at main frame And the technique carried out is UV/TiO₂+O₃+H₂O₂Processing, this treatment process is to ensure that the phenyl amines organic contamination of extremely difficult degraded The clearance of thing is up to standard.

ASBR process in native system, it enters discharging mode is " the modern bright row of water " pattern.That is:

1. add new waste water during the morning 8 on the same day, run to 5:30 in afternoon daytime the most continuously, then shut down (precipitation).

2. release treated water during the next day of the morning 8, add new water running.

In other words, the water that ASBR processes today is the draining that electrolysis yesterday processes, and is electrolysed and processes the water on the same day through a night Just add in ASBR to morning next day after clarification.

3. batch-type ASBR equipment is simple, simple to operate, manufactures and operating cost is low.And high-concentration sewage can be processed.

The operation principle of ASBR is i.e. the new of anaerobic bacteria group carrying out to survive of utilizing that Organic substance in water carried out Old metabolism biochemical reacts.

Such as Figure 10, after antibacterial decomposes complicated Organic substance, just utilize and decompose obtained material (bacteriotrophy material) and instead The new cell of the energy synthesis that should release oneself, so that oneself increases.And this life style of antibacterial objectively helps me The Organic substance removing in water of degrading.

SBR (Sequencing Batch Reactor) is i.e. that sequence criticizes (intermittently) formula aerobic activated sludge bioreactor. SBR is the advanced method in water-treatment biological processing method in the present age.

Sbr reactor device structure in native system is shown in Fig. 8, including with lower component: 51. drain valves, 52. air pumps, 53. air inlets Pipe, 54. drain valves, 55. intake valves.

It uses blast aeration mode oxygenation.It is designed as a size of 500 × 500 × 600mm open type rustless steel to hold Device.Use air pump pressure wind enter aeration head from bottom by air even dispersion in waste water, cause activated sludge and oxygen and give up Being thoroughly mixed of Organic substance in water.

1. the SBR in native system, it is identical with ASBR that it enters discharging mode, i.e. " the present, water was bright to put ".

2. SBR Inlet and outlet water and ASBR have the time difference, it may be assumed that the water that SBR processes today is the water that yesterday, ASBR processed, and is the day before yesterday The water that electrochemistry host process is crossed.

3. SBR is easy and simple to handle, and investment and operating cost are low, and high treating effect.

Such as the operation principle of Figure 11, SBR bioreactor, it is exactly substantially that aerobic bacteria utilizes pollution in water to survive Organic substance does the metabolism biochemical reaction that nutrient substance is carried out.

It is the most i.e. that aerobic bacteria utilizes the Organic substance in water to carry out anabolism and synthesize the cellular material of oneself (C₅H₇NO₂), carry out catabolism the most again and generate H₂O, CO₂, NH₃Deng metabolite, then, complicated organic in water Thing is just converted into inorganic matter and makes pollutant in water be degraded and remove.

Laboratory liquid waste treatment system is integrated with current state-of-the-art water technology, and has accomplished the electromechanical of equipment Change and miniaturization.These advanced technologies mainly have:

Table 1 main frame+ASBR+SBR commencement of commercial operation experimental result

Can obtain and such as draw a conclusion from table 1:

(1), main frame+ASBR+SBR runs is successful.

(2), the CODcr clearance of three sections of alternating impulse electrolysis has belonged to optimum 80%～90%.UV/TiO₂+O₃+H₂O₂ Process and mainly phenyl amines and nitrobenzene matters are degraded, and be difficult to improve again to the degradation efficiency of small organic molecule. It is effective to complicated organic matter degradation that its reason is because high-level oxidation technology, and the effect of the simple organic degraded to short carbon chain The most not ideal.Owing to ozone adds three sections of pulse electrolysis UV/TiO₂+O₃+H₂O₂The strong oxidation processed makes Organic substance all become For short carbon Organic substance, therefore efficiency cannot improve again.

(3) the CODcr, within ASBR Yu SBR, along with the increase of continuous number of run, creates CODcr gradually inside it The phenomenon of accumulation, this phenomenon eventually results in process waste water after a certain time of operation can not qualified discharge.Therefore, running When if the CODcr accumulation of ASBR Yu SBR has a strong impact on discharge index in, so stopping into Xin Shui, but do not stop its operating, After being depleted to accumulation, continue to put into operation, it is also possible to replace with new activated sludge.

The following is the total chromium of investigation and the test of aniline category matter removal effect

Due to somewhat expensive needed for the total chromium of test and phenyl amines, therefore use 10 realities that a certain true waste liquid is carried out Testing mixing average water determination its average total chromium and content of aniline category matter after process, result is table 2.

The effect that the total chromium of table 2 and aniline category matter remove

As can be drawn from Table 2 to draw a conclusion:

(1) through main frame, the process of ASBR and SBR tandem, the final process CODcr of water, total Cr and Aniline categories Residual concentration, already below relevant discharge standard, can drain into sewer.This demonstrate this set processing means and process so-and-so The effect of waste liquid is comparatively ideal.

(2), in host process, remove the CODcr except 80%～90%, and by total Cr and phenyl amines environment conservative substance Disposably process to discharge standard, illustrate high efficiency and the advance of main frame group technology.

The design of " environmental protection flower bed " land treatment system

Design theory with experimental basis is:

(1) experiments prove that: flyash and soil have selective adsorption capacity to the Organic substance in waste water.

Experiment display, carries out activated adoption to the host process clear liquor of CODcr=21 444mg/L, at absorption load is Under conditions of 31gCODcr/kg flyash, through absorption in 8 hours, the selective absorption efficiency of 73% can be obtained.

(2) mainly can be with biodegradable small organic molecule due to the Organic substance in waste liquid, therefore can be by soil Activity that earth, microorganism and Lumbricus etc. are miniature and obtain degraded.

(3) the design can not only be used for the outdoor series connection insurance technique of this device systems, simultaneously within the specific limits can also be straight Connect and simplification handling process is used in combination with main frame.This is the processing method of a kind of simplification for not having the area of municipal sewage system.

The following is properity and the operation principle of " environmental protection flower bed "

In native system, the what is called " environmental protection flower bed " of exploitation should be referred to as that " flyash, adsorption by soil are held concurrently microorganism technically With Lumbricus bio-reaction bed ".

Specifically, described environmental protection flower bed system includes altar body, vent filter gravel layer 63, gravel ventilation well 64, waste water The adsorption layer of aqua storage tank 65, flyash, soil, activated sludge mixing composition is held concurrently microorganism/Lumbricus bed 66, sand particles filter ventilation Layer 67, water distributor 68 of watering flowers, resistance to fertile flowers and plants 69 and water distributor regulation valve 60；Described filter gravel layer 63, sand particles filter ventilation layer 67 and flyash, soil, the adsorption layer microorganism/Lumbricus bed 66 of holding concurrently of activated sludge mixing composition set gradually from the bottom up；Institute Stating gravel ventilation well 64 to be plugged in altar body, ventilate with vent filter gravel layer UNICOM and for it in its one end, described waste water Aqua storage tank 65 is arranged on the top of altar body and connects with water distributor 68 of watering flowers.

61. gutter in figure, 62. ventilation nets, 63. vent filter gravel layers, 64. gravel ventilation wells, 65. waste water water storages Groove, the adsorption layer of 66. flyash, soil, activated sludge mixing composition, microorganism/Lumbricus bed of holding concurrently, 67. sand particles filter ventilation Layer, 68. water flowers water distributor, 69. resistance to fertile flowers and plants, 60. water distributors regulation valves.

This facility is the flower bed that can ventilate, and flower bed bottom gravel is breathed freely well.Above gravel layer, by Grain order from big to small inserts flyash, soil, activated sludge mixing soil materials in flower bed, until filling up, same banket Time insert " internal layer " Lumbricus seedling.Resistance to fertile HUAMU is planted on flower bed.Having waste water water reservoir above flower bed, water passes through bottom sparge pipe Waste water is uniformly spilled in flower bed by net, gradually lower leaching.During water down soaks, the flyash etc. inhaling renaturation energy extremely strong selects Property adsorbed the Organic substance in water, decompose edible for microorganism and Lumbricus, part water then with salts substances in water by gravel Rock layers bottom is discharged into sewer.

The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvements and modifications, these change Enter and retouch and also should be regarded as protection domain of the present utility model.
