Background technology
The clever agricultural chemicals waste water of hundred grass is a kind of intractable organic chemical waste water, is mainly characterized by:1. pollutant concentration compared with Height, COD (COD) is up to every liter of tens thousand of milligram;2. toxicity is big, in waste water in addition to containing pesticide and intermediate, also contain The noxious materials such as phenol, arsenic, mercury and many biologies are difficult to the substance degraded;3. foul smelling, the respiratory tract to people and mucous membrane spinosity Swash property;4. water quality, water are unstable.The discharge of the clever agricultural chemicals waste water of hundred grass causes extensive pollution of area source, and the duration is long, residual Pesticide it is very big to Health Impact.For These characteristics, it is difficult that processing is up to standard using conventional biochemical process, needs one kind more The method that a treatment process is combined reduces high COD in the clever agricultural chemicals waste water of hundred grass and eliminates the toxicity in waste water, decomposes difficult to degrade Organic matter, increase the biodegradability of biology, reach discharge standard, and then eliminate agricultural chemicals waste water with wastewater disposition to surrounding Pollution caused by environment.
Invention content
Present invention aims at providing hundred grass of one kind clever agricultural chemicals waste water processing method, to solve defect in the prior art.
In order to solve the above technical problems, the technical solution adopted by the present invention is:
1) microelectrolysis processing:Waste water passes into light electrolysis equipment from water inlet first, and light electrolysis equipment uses big anode Small cathode micro machine device, in a device in special ratio filling by waste iron filing and inertia carbon particle, when by iron filings and carbon particle When being immersed in acid waste water, numerous micro- primary battery can be formed due to the difference in Electrode Potential between iron and carbon, in waste water, wherein The low iron of current potential becomes anode, and the high carbon of current potential becomes cathode, which can be by the phenol type organic open loop, disconnected in waste water Chain provides basis for next stage;
2) ozone high grade oxidation is handled:Waste liquid through light electrolysis equipment preliminary treatment enters smelly under the action of promoting water pump Oxygen contact chamber, water electrolytic ozone reactor generate a kind of extremely strong oxidant, enter under the action of high-pressure pump and the ultrasonic liquid whistle Ozone contact tank can aoxidize most of organic matter, make organic matter open loop, chain rupture;Meanwhile ozone is by the way of the ultrasonic liquid whistle It adds, generates " ultrasonic cavitation " and " Hydrodynamic cavitation ", can decompose and to generate largely than ozone activity higher, and almost non-selectivity Hydroxyl radical free radical, can be difficult in degradation water by the organic matter of ozone direct oxidation, to go most of in water removal difficult to degrade have When machine object, while excessive ozone can regenerate subsequent activated carbon;
3) activated carbon is handled:It, may still remaining be a small amount of undegradable has after light electrolysis is reacted with aqueous ozone Machine object, into after activated carbon reactor, organic matter is adsorbed in the gap of activated carbon, and ozone is further the organic matter of absorption Removal realizes that the separation of hydraulic detention time and ozone reaction time, the water up to standard that final process is crossed enter production pond.
The electrode of the ozone reactor uses SnO2-Sb2O5One layer graphene of centre covering, cathode is activated carbon, in sun Titanium net graphene adhesive layer is added between pole and cathode, both ends are not direct with cathode, positive contact.
Advantageous effect:Compared with original technology, the clever agricultural chemicals waste water processing method processing of hundred grass of one kind of the invention is toxic, difficult Biochemistry, high COD and the waste water for having serious inhibiting effect to microorganism;Easy to operate, high treating effect can effectively decompose difficult drop The organic matter of solution eliminates the toxicity of waste water, and processing totle drilling cost is low, can handle high-concentration pesticide wastewater, economical and practical, ensures water outlet Discharging standards can be reached.
Description of the drawings
Fig. 1 is the process route view of the present invention;
Wherein:1- light electrolysis equipment, 2- promote water pump, 3- Roots blowers, 4- ozone reactors, 5- high pumps, 6- ultrasounds The wavefront whistle, 7- ozone contact tanks, 8- activated carbon reactors, 9- produce pond.
Specific implementation mode
Technological means, feature, reached purpose and effect to make the present invention realize are easy to understand, with reference to specific Embodiment, the present invention is further explained.
As shown in Figure 1, the clever agricultural chemicals waste water processing method of hundred grass of one kind, it is characterised in that processing method includes the following steps:
1) microelectrolysis processing:Waste water enters light electrolysis equipment 1 from water inlet first, and light electrolysis equipment 1 is small using big anode Cathode micro machine device in a device in special ratio filling by waste iron filing and inertia carbon particle is soaked when by iron filings and carbon particle When not in acid waste water, numerous micro- primary battery can be formed due to the difference in Electrode Potential between iron and carbon, in waste water, wherein electricity The low iron in position becomes anode, and the high carbon of current potential becomes cathode, the step can by the open loop of phenol type organic, the chain rupture in waste water, Basis is provided for next stage, Roots blower 3 can effectively slow down the problem of passivation of light electrolysis;
2) ozone high grade oxidation is handled:Waste liquid through 1 preliminary treatment of light electrolysis equipment enters under the action of promoting water pump 2 Ozone contact tank 7, ozone reactor 4 generate a kind of ozone that oxidisability is extremely strong, under the action of high-pressure pump 5 and the ultrasonic liquid whistle 6 Into ozone contact tank 7, most of organic matter can be aoxidized, makes organic matter open loop, chain rupture;Meanwhile ozone is using the ultrasonic liquid whistle 6 Mode add, generate " ultrasonic cavitation " and " Hydrodynamic cavitation ", can decompose and generate largely than ozone activity higher, and almost without choosing The hydroxyl radical free radical of selecting property can be difficult to by the organic matter of ozone direct oxidation in degradation water, to go most of difficult drop in water removal When the organic matter of solution, while excessive ozone can regenerate subsequent activated carbon;
3) activated carbon is handled:It, may still remaining be a small amount of undegradable has after light electrolysis is reacted with aqueous ozone Machine object, water enter activated carbon reactor 8, organic matter are adsorbed in the gap of activated carbon, ozone further having absorption Machine object removes, and realizes that the separation of hydraulic detention time and ozone reaction time, the water up to standard that final process is crossed enter production pond 9.
Wherein, the electrode of the ozone reactor 4 uses three-diemsnional electrode, i.e., in SnO2-Sb2O5One layer of graphite of centre covering Alkene, cathode are activated carbon, titanium net graphene adhesive layer are added between the anode and cathode, both ends are not direct to be connect with cathode, anode It touches.
