Embodiment
Referring to Fig. 1, micro-polluted water treatment unit of the present invention comprises: pretreatment unit 1, water collecting basin 3, ozone contact tank 5, between ozone preparation 6, biological activated carbon filter 8 and Aeration fan 12, this pretreatment unit 2 is provided with the water-in 1 that enters for processed micro-polluted water, pretreatment unit 2 outlets are connected by the inlet of pipeline with water collecting basin 3, in this water collecting basin 3, be equipped with and promote water pump 4, this outlet that promotes water pump 4 is connected by the inlet of pipeline with ozone contact tank 5, in this ozone contact tank 5, be provided with pectination, up and down to several slotting flow deflectors 17, between adjacent flow deflector 17, respectively be provided with ozone shower nozzle 7, each this ozone shower nozzle 7 is all by 6 being connected between the preparation of ozone pipeline 18 and ozone, and the outlet of this ozone contact tank 5 and the water-distributing device of biological activated carbon filter 8 enter the mouth and 19 be connected.
Described biological activated carbon filter 8 comprises pond body 16, water-distributing device 9, filter and back up pad 20, distribution device 10, carbon leaching material layer 21, purify waste water water receiving tank 14 and wash-down water water receiving tank 13, be disposed with water-distributing device 9, filter and back up pad 20, distribution device 10 and carbon leaching material layer 21 in pond body 16 from bottom to up, the inlet of described water-distributing device inlet 19 and distribution device 10 all passes outside this pond body 16.Be provided with the wash-down water water receiving tank 13 and the water receiving tank 14 of purifying waste water in the outside of the upper port of this pond body 16, the water receiving tank 14 of purifying waste water is located at the outside of wash-down water water receiving tank 13.
The top, outer of this wash-down water water receiving tank 13 is lower than the top, outer of the water receiving tank 14 of purifying waste water, and is higher than the upper end of pond body 16.Be respectively equipped with wash-down water outlet 15 and treated water outlet 11 in the bottom of this wash-down water water receiving tank 13 and the water receiving tank 14 of purifying waste water.
Described water-distributing device 9, distribution device 10 and filter and back up pad 20 are prior art.
Principle of work of the present invention and function declaration are as follows:
Pretreatment unit 1: can adopt net filter or husky filter or other physical filtering modes, the suspended substance in the water and some algae are filtered, dam, reduce the suspension content that enters the subsequent disposal structures, reduce the influence of suspended substance to gac.
Ozone contact tank 5: come the ozone that water and ozonizer send can thorough mixing, major advantage is as follows: (1) ozone can be removed the part easily biodegradable organics, reduce total amount of organic, and can improve organic biodegradability by changing organic molecular structure, the long-chain organic matter degradation is become the short chain organism, hardly degraded organic substance is oxidized to easily biodegradable organics, it is removed in follow-up biochemical treatment process as far as possible.(2) ozone can be removed the trichloromethane parent thing in the former water effectively, and the trichloromethane growing amount when chlorine disinfectant is atomic again to make treat effluent.(3) ozone removes the effect of smelling obviously, and when water body generation in summer wawter bloom, ozone can effectively be removed the peculiar smell in the water.(4) the mutagenesis activity of water body significantly improves after the ozonize, has improved safe drinking water.
Biological activated carbon filter 8: utilize the huge specific surface area of gac,, make microorganism, solved the problem that conventional contact oxidation method is handled micro-polluted water biofilm difficulty in activated carbon surface growth, breeding for microorganism in the water provides the carrier of depending on for existence.System's initial operating stage, microbial biomass is less, activated carbon surface hangs that modulus is less, charcoal absorption has been played important effect to pollutant removal, gac is the dissolved organic matter in the planar water rapidly, the while microorganism in also can enrichment water.Prolongation along with the time, the adsorption meeting weakens gradually, activated carbon surface is hung modulus to be increased gradually, the organism in water amount increases, microbial process will dominate, and the large amount of organic of activated carbon surface absorption has been also for microorganism provides good living environment, and microorganism is growth, the breeding that nutriment carries out self with the organism under the abundant dissolved oxygen environment having, reduced pollutant load simultaneously, purifying water body.
Treatment unit working process of the present invention is: at first micro-polluted water enters pretreatment unit 2 by water-in 1, suspended substance is trapped in this pond, water outlet is from flowing into water collecting basin 3, be promoted to ozone contact tank 5 by promoting water pump 4, and in ozone contact tank 5 with the abundant contact reacts of ozone that discharges by ozone shower nozzle 7, water outlet is from flowing into biological activated carbon filter 8, water-distributing device 9 can make sewage evenly enter biological activated carbon filter 8, distribution device 10 can make even air enter biological activated carbon filter, carry out oxygenation, sewage rises and fully contacts with biological activated carbon 21, and pollutent is degraded in this pond, handles the back water outlet and is discharged by treated water outlet 11.
Operation for some time need wash biological activated carbon filter 8, and the specific operation process of flushing is:
When the filter tank need be washed, at first close the valve of inlet of valve, the distribution device 10 of water-distributing device inlet 19, the valve of opening wash-down water outlet 15 then carries out draining, when body 16 median water level in pond are reduced to flushing water level D1, the valve (flow is greater than the flow of works better) of the valve (suitably regulating flow) of unlatching water-distributing device inlet 19 and the inlet of distribution device 10 carries out air water to the filter tank and unites flushing.Wash-down water is discharged by wash-down water outlet 15 after being collected by wash-down water water receiving tank 13, and the inlet that can be transported to ozone contact tank is handled again.
The advantage of above-mentioned flushing is:
1, the flushing of precipitation position has reduced wash-water pump and the required pressure of flushing blower fan because the filter tank median water level reduces, and has saved the energy.
2, the flushing of precipitation position at first reduces the filter tank median water level; for gac provides expansion area; make that gac rolls, rubs with the lower section at ordinary water-level in the recoil process; microbial film is broken away from; the microbial film that comes off is with the wash-down water outflow system; this process has reduced the friction probability of gac and upper strata catch net, reduces the wearing and tearing and the loss of gac.
