Operation principle of the present utility model and feature:
This utility model adopts the MAC adsorbent that Guan Yu water resource scientific & technical corporation produces. MAC adsorbent is different from traditional activated carbon adsorbent. Traditional active carbon adsorbent process is to adsorb in the hole of activated carbon surface by the pollutant in sewage, it is difficult to be removed by simple backwash mode in activated carbon hole once adsorb, COD pollutant not easily pass in and out pore, so the adsorption capacity of conventional adsorbent is low, service life is not high. And the MAC adsorbent of the Guan Yu water resource scientific & technical corporation that this utility model adopts, utilize the physical action of surface functional group, through electrostatic attraction or the Fan Dewa power of hearing, pollutant in sewage are adsorbed on MAC adsorbent surface, again through the hydroxyl radical free radical (OH) that MAC sorbent catalyst ozone produces, carry out advanced oxidation process (AOP), directly the COD pollutant oxidation of adsorbent surface is fallen. Such MAC adsorbent is just renewable, repeats absorption. The starting material source making MAC adsorbent is a lot, including: activated carbon (from coconut husk, Colophonium, or ature of coal), and develop as MAC adsorbent with agricultural waste for starting material. One of inventor of the present utility model, has applied to become Chinese patent " CN103787443A-flows through formula adsorber in order to what remove total solution property solid " by the research of twice laid.
Character and process target according to waste water, traditional active carbon can use specific medicament, carry out surfaction, make the MAC adsorbent of " suiting the remedy to the case ", make MAC adsorbent " to have selective " and remove the TDS (including desalinizing seawater) in waste water, COD, BOD, TOC, phosphorus, ammonia nitrogen or arsenic etc. After upgrading, the original surface texture of activated carbon is all constant with hole, therefore MAC adsorbent still has except color, deodorization, except volatile organic gas (VOC), except a small amount of heavy metal ion, and removes the inherent character of the activated carbon of SS. MAC adsorbent is also the same with activated carbon is reducing agent, can adsorb ozone, and by ozone decomposed. The shape of activated carbon has powdery with granular, all may be used to manufacture MAC adsorbent. But, powdered activated carbon has to pass through prilling, makes granular MAC adsorbent, allows the water to flow through smoothly the packed column of MAC adsorbent, accepts purified treatment.
MAC adsorbent and ozone are two essential elements of the present utility model, by the addition between them, reach the effect of quick advanced treating COD.This utility model uses online ozonator (EO3) device, with low dc voltage (24V or following) electrolysis tap water or waste water, water directly produces ozone. As the electrolysis of water: anode produces oxygen, and negative electrode produces hydrogen. But, after anode plates one layer special catalyst, during electrolysis, anode except oxygen, also produces ozone (yield of oxygen and ozone than close to 3:2). The technology of the food stage catalyst of ozone illustrates, is referred to the U.S. Patent No. 9,174,859 of one of inventor of the present utility model. When ozone generates in water, first come across anode surface with the bubble of secondary micron, then grow up to micron order and just leave anode. Therefore, online ozone generator (EO3) ozone need not as the glow discharge of traditional " electrolysis air produces ozone ", it is necessary to by ozone dissipation in water, and glow discharge cannot produce as online ozone generator (EO3) minute bubbles just like that. The bubble of ozone is less, and reaction rate is faster.
Chemically angle is seen, ozone is oxidant, and MAC adsorbent or activated carbon are reducing agent, and both meet in water, and " oxidation-reduction, oxidation-reduction " reaction (English abbreviation redox) just occurs automatically. The phenomenon of aforementioned automatic redox, also at potassium permanganate (KMnO4) and activated carbon between produce, activated carbon can by KMnO4It is reduced to MnO2. The difference is that, the redox reaction of ozone/MAC adsorbent occurs at room temperature, and KMnO4/ activated carbon redox reacts, then must heat to 60-80 DEG C.
The redox of ozone and MAC adsorbent reacts [namely ozone is decomposed by MAC sorbent catalyst, becomes the process of hydroxyl radical free radical (OH)], first from the surface that ozone molecule is adsorbed on MAC adsorbent. Ozone (O3) it is reduced to OH on this surface by MAC adsorbent-Ion, such as equation (1). Then, O3With OH-Ionic reaction, forms the peroxy radical (superoxideradical) in equation (2):
O3+OH-��O2 -��+HO2��(2)
The starting (initiation) that equation (1) and (2) are chain reaction. O3Again with peroxy radical circular response, such as equation (3) and (4):
O3+HO2������OH+2O2(3)
O3+��OH��O2+HO2��(4)
The transmission (propagation) that equation (3) and (4) are chain reaction. Finally, hydroxyl radical free radical OH is combined with each other, and becomes hydrogen peroxide (H2O2):
2��OH��H2O2+O2(5)
The termination (termination) that equation (5) is chain reaction
The O of upper speed equation (1) to (5)3OH is produced in the absorption of MAC adsorbent surface and catalysis, and the absorption in MAC table face of the COD Organic substance and degraded, it is shown in Fig. 1:
Eliminating organic cod with ozone and relatively eliminate the inorganic matter COD more ozone of consuming, eliminating 1mg by the organic cod of ozone oxidation, can must expend 2.5mg ozone (except H2S, eliminating 1mg inorganic matter COD need only 0.44-0.88mg ozone), and the reaction rate of ozonisation is slow, and some organic cods are at all helpless. Such as, acetone (cannot by ozone oxidation) and ethanol (by ozone oxidation to acetaldehyde, reaction just pauses). Therefore, the elimination of COD need an oxidant more powerful than ozone, answer is exactly hydroxyl radical free radical (OH), and the reaction of all COD pollutant of degrading with OH, is just called advanced oxidation processes (English code name: AOP). Table 1 lists the oxidizing potential of some oxidants, and order arrangement from high to low, the oxidant that oxidizing potential oxygen is higher, the ability decomposing COD is just stronger.
The oxidizing potential of some oxidants of table 1
It addition, table 2 compares reaction rate (unit: the M of ozone and hydroxyl radical free radical (OH) some organic cods of oxidation Decomposition-1��sec-1, M is mole concentration, the mole mol number namely contained in 1 liters of water, M=mol/L):
Table 2O3With the reaction rate that OH decomposes some organic C OD pollutant
Table 2 shows the reaction rate of hydroxyl radical free radical (OH) oxidation Decomposition organic C OD pollutant, ratio ozone fast million times, describes importance and its economic worth of AOP.Thus it is possible to produce the technique of hydroxyl radical free radical (OH) in the way of " easily and fast, economical ", " environmental conservation " will can be made maximum contribution. Table 3 lists the method for the generation hydroxyl radical free radical (OH) being verified:
The technique that table 3 produces OH in water
4th " O of table 33+ activated carbon ", MAC adsorbent not only specific activity carbon can adsorb a greater variety of pollutant, and adsorption capacity is also higher. Therefore " O3+ MAC adsorbent " it is a water treatment system innovated. Meanwhile, with online ozone generator (EO3) " the online ozone that supply is appropriate in real time ", make " EO3+ MAC adsorbent " environmental protection, the reason requirement of energy-conservation highest point can be reached.
The photooxidation (UV) that this utility model adopts, ozone, hydrogen peroxide combination oxidised form, make use of its oxidation and photolysis, including the oxidation that hydroxyl free radical OH is master that the direct oxidation of ozone, ozone and decomposing hydrogen dioxide solution produce, and hydrogen peroxide, ozone photodissociation and dissociation, pollution in sewage is aoxidized, and oxidation results, Organic substance is thoroughly degraded to CO2And H2The innocuous substances such as O. Relatively and other chemical oxidations, the oxidant such as ozone, hydrogen peroxide individually aoxidizes, and has incomparable advantage.
The process device of physical adsorption techniques and the high-level oxidation technology combination that this utility model adopts and process technique, the pollutant in sewage can be made to transfer to physical absorbent surface fast and effectively on the one hand, enable sewage processed clean within the shortest time; Adopt photooxidation (UV), ozone, hydrogen peroxide combination oxidised form, the organic pollution harmless treatment thoroughly in sewage and MAC table face can adsorbed on the other hand. So the mode of combination, can make device use continuously, and physical absorption is in unsaturated state all the time, need not carry out parking backwash.
This device can according to the different demand of salt contained in sewage, COD index, by on-line computing model, data are carried out online acquisition, and by PLC process, regulate the indexs such as the inflow of system, ozone generation amount, photooxidation reaction time, hydrogen peroxide addition. Adapt to multiple different organic wastewater.
