Under the situation that current water pollutions is on the rise, water technology is progressively upgraded, and membrane technology, as an emerging isolation technique, water treatment is more and more applied.Reverse osmosis (RO) membrane technique is the new separation technology risen the sixties in 20th century.In the reusing sewage of the industries such as oil refining, printing and dyeing, petrochemical industry, obtain sizable application based on the embrane method advanced treatment process of ultrafiltration, reverse osmosis, it has the advantages such as flow process is simple, easy to operate, floor space is little.Under normal circumstances, the actual producing water ratio of reverse osmosis process, less than 75%, about has the dense water of 25%.Containing various organic and inorganic pollutant in reverse osmosis (RO) dense water, if directly discharge may produce pollution to soil, surface water, ocean etc.; If enter municipal sewage system, too high total dissolved solid is also very unfavorable to the growth of active sludge.
The dense water of RO is the concentrated waste water through film process after biochemical treatment, and advanced treatment difficulty is larger.At present, the rate of recovery, directly or indirectly discharge, comprehensive utilization, evaporation concentration, removal pollutent etc. are improved to the processing mode of the dense water of RO both at home and abroad.How efficiently degradation of organic substances and reduction energy consumption are the method process RO dense water institute facing challenges.
Summary of the invention
For above-mentioned technical problem, the purpose of this utility model is to provide and RO concentration can be discharged, the dense water treatment device of a kind of RO that processing cost is low.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of reverse osmosis concentrated water treatment device, it is characterized in that: comprise the equalizing tank be connected successively by pipeline, ultrasonic pond, settling tank, iron-carbon micro-electrolysis reactor, adsorption unit, the pipeline between described equalizing tank and ultrasonic pond is provided with Fenton medicament adding device; Between described ultrasonic pond and settling tank, pipeline is provided with coagulated agent adding set; Described adsorption unit is connected with a regneration of adsorbent material device.
Further, in described iron-carbon micro-electrolysis reactor, iron carbon filler is housed, described iron carbon filler is oval iron carbon granule, and particle diameter is 1-2cm; The bottom of described iron-carbon micro-electrolysis reactor is provided with microporous aeration disc, hardens to prevent iron carbon granule for aeration.
Further, the sorbing material in described adsorption unit is modified activated carbon.
Adopt technique scheme, reverse osmosis concentrated water treatment device described in the utility model, the beneficial effect had is:
1) the multiple further treatment technique such as ultrasonic assistant Fenton, iron-carbon micro-electrolysis, absorption are coupled together, for the treatment of the dense water of the RO being difficult to biological degradation process, have the feature of various further treatment technique concurrently, dense for RO water effectively can be processed qualified discharge;
2) sorbing material adopts bio-regeneration or thermal regeneration technology, and the sorbing material after regeneration can recycle, and saves processing cost;
3) adopt iron-carbon micro-electrolysis, electrolysis can play the organic effect of process difficult for biological degradation on the one hand, and on the other hand, relatively general electrolytic process, does not need to connect electricity, saved energy consumption.
Accompanying drawing explanation
Fig. 1 is reverse osmosis concentrated water treatment device schematic diagram described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, reverse osmosis concentrated water treatment device described in the utility model, comprise the equalizing tank be connected successively by pipeline, ultrasonic pond, settling tank, iron-carbon micro-electrolysis reactor, adsorption unit, the pipeline between described equalizing tank and ultrasonic pond is provided with Fenton medicament adding device; Between described ultrasonic pond and settling tank, pipeline is provided with coagulated agent adding set; Described adsorption unit is connected with a regneration of adsorbent material device; In described iron-carbon micro-electrolysis reactor, iron carbon filler is housed, described iron carbon filler is oval iron carbon granule, and particle diameter is 1-2cm; The bottom of described iron-carbon micro-electrolysis reactor is provided with microporous aeration disc, hardens to prevent iron carbon granule for aeration; Sorbing material in described adsorption unit is modified activated carbon.
Concrete, each structure function of reverse osmosis concentrated water treatment device described in the utility model is as follows:
Equalizing tank: mix well water quality, adds dilute sulphuric acid and regulates pH2.5-3.5, be beneficial to Fenton's reaction and carry out;
Ultrasonic pond: ultrasonic assistant Fenton's reaction, temperature is between 25-35 DEG C, and ultrasonic wave and Fenton method act synergistically, and ultrasonic cavitation effect and the temperature that causes thereof can be utilized to raise and contact with fully stirring, impel Fenton reagent to produce a large amount of OH rapidly in reaction process, thus improve H
2o
2utilization ratio, promote the process to the dense water of RO;
The Fenton medicament added before ultrasonic wave is FeSO
4and H
2o
2; Add coagulating agent PAC and PAM afterwards, precipitate.
Iron-carbon micro-electrolysis reactor: be placed with iron carbon filler in device, filler is oval iron carbon granule, and particle diameter is about 1-2cm; The bottom of reactor is provided with microporous aeration disc, hardens to prevent iron carbon granule for aeration;
Adsorption unit: interior filling efficient adsorption material is modified activated carbon;
Regneration of adsorbent material device: saturated sorbing material is put into bio-regeneration liquid, regenerates 8-24h under 40-60 DEG C of condition, obtains the sorbing material after regenerating; Or thermal regeneration, by regeneration after saturated sorbing material drying, high temperature carbonization and activation; Sorbing material after regeneration is put back in adsorption unit, recycles.
During concrete use, through the dense water of the RO being difficult to biochemical degradation process that reverse-osmosis treated obtains, mix well water quality, acid adjustment through equalizing tank, then through ultrasonic assistant Fenton's reaction, remove the organism of difficult degradation, then through coagulating kinetics, remove most of pollutent; Then enter iron-carbon micro-electrolysis reactor for treatment, then enter adsorption unit to remove the pollution substance in water further, last qualified discharge; Sorbing material, after regenerating unit regeneration, recycles.
