Abstract
The utility model discloses a landfill leachate pre-treatment device based on ozone micro-air bubbles. The landfill leachate pre-treatment device comprises an adjusting tank, an anaerobic tank, an oxygen-poor tank, an aerobic tank, a submersible sewage pump, a fan and an ozone generator, wherein the adjusting tank is used for collecting landfill leachate; the submersible sewage pump is arranged in the adjusting tank and is used for conveying the landfill leachate in the adjusting tank into the anaerobic tank; the anaerobic tank, the oxygen-poor tank and the aerobic tank are connected in sequence; a water outlet of the aerobic tank is a water outlet of the landfill leachate pre-treatment device; micro-pore aeration devices are arranged at the bottom of the oxygen-poor tank and the bottom of the aerobic tank; an outlet of a fan is respectively connected with the micro-pore aeration device of the oxygen-poor tank and the micro-pore aeration device of the aerobic tank by an air pipe; the outlet of the ozone generator is connected with the air pipe by an ozone conveying pipe. According to the landfill leachate pre-treatment device based on the ozone micro-air bubbles, the micro-pore aeration devices adopt an air and ozone mixed gas source so that the use amount of the aeration gas source can be saved; the removing effects of organic matters and chroma in the landfill leachate and the inactivation degree of bacteria are improved by using the high oxygen content.
Description
Technical field
The utility model relates to a kind of percolate pretreatment unit, relates in particular to a kind of percolate pretreatment unit based on ozone microbubble.
Background technology
Percolate refers to and derives from the moisture that in refuse landfill, rubbish itself contains, the sleet water that enters landfill yard and other moisture, the saturation moisture capacity of deduction rubbish, overburden layer, and experience waste layer and overburden layer and a kind of high-concentration waste water of forming.
The processing of percolated liquid in city refuse landfill is unusual stubborn problem in Landfill Site Design, operation and management always.The treatment process of percolate comprises physico-chemical processes and biological process.Physico-chemical processes mainly contains the several different methods such as charcoal absorption, chemical precipitation, density separation, chemical oxidation, chemical reduction, ion-exchange, film dialysis, air lift and wet oxidation process, when COD is 2000～4000mg/L, the COD clearance of physical chemistry method can reach 50%～87%.Compare with biological treatment, the impact that is not subject to water quality and quantity variation is processed in materialization, and effluent quality is more stable, especially to BOD
5/ COD ratio lower (0.07～0.20) is difficult to the percolate of biological treatment, has good treatment effect.But physical chemistry method processing cost is higher, be unsuitable for the processing of big yield percolate, therefore percolate processing is mainly to adopt biological process.
In the biological process adopting is at present processed, conventionally by blower fan, utilize air to carry out oxygenation, so need a large amount of air just can reach good aeration effect, cause aeration efficiency deficiency and the large problem of blower fan energy consumption; In addition, due to oxygen level deficiency, also can cause organism, the removal effect of colourity and the deactivation degree of bacterium in percolate not ideal enough, the later stage advanced treatment burden of percolate is increased.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem the percolate pretreatment unit based on ozone microbubble that a kind of aeration consumption of air source is low and treatment effect is good.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Percolate pretreatment unit based on ozone microbubble described in the utility model comprises equalizing tank, anaerobic pond, anoxic pond, Aerobic Pond, submersible sewage pump, blower fan and ozonizer; Described equalizing tank is used for collecting percolate, described submersible sewage pump is placed in described equalizing tank and for the percolate in described equalizing tank is delivered in described anaerobic pond, described anaerobic pond, described anoxic pond and described Aerobic Pond are connected successively, and the water outlet of described Aerobic Pond is the water outlet of described percolate pretreatment unit; The bottom of described anoxic pond and the bottom of described Aerobic Pond are respectively arranged with micro-hole aerator, the outlet of described blower fan is connected with the micro-hole aerator of described anoxic pond and the micro-hole aerator of described Aerobic Pond respectively by airduct, and the outlet of described ozonizer is connected with described airduct by ozone transfer lime.
Above-mentioned each parts are existing matured product, wherein, micro-hole aerator is for aeration aerating, concrete structure is determined as required, such as being suspension type chain type aerator, microporous diaphragm aerator, rotary cutting aerator, tube aerator, plate-type aerator, micro-pore ceramic aerator, hose type aerator etc.
The beneficial effects of the utility model are:
First the utility model utilizes anaerobic reaction and hypoxia response the organic substance decomposing of difficult degradation in percolate to be become to the organism of easy degraded, laggard row aerobic reaction, and by the micro-hole aerator of anoxic pond and the micro-hole aerator of Aerobic Pond, be filled with the mixed gas of air and ozone, make it produce ozone microbubble, because oxygen level in the ozone of ozonizer generation is very high, reach more than 80%, so significantly improved utilization ratio and the aeration efficiency of aeration source of the gas, saved aeration source of the gas consumption; Meanwhile, utilize the high reactivity of ozone can obviously improve the removal effect of organism, colourity and the deactivation degree of bacterium, improve the pretreating effect of percolate, for the later stage advanced treatment of percolate reduces the heavy burdens; Percolate pretreatment unit described in the utility model entirety composition integration apparatus, its integrated level is high, running cost is low, stable, take up an area less and be convenient to mobile.
