According to the system, a photo-catalytic system is combined with ozone, ozone is taken as an oxidant to generate.OH under the action of optical radiation, and organic matters in wastewater are attacked by virtue of the strong oxidation of the.OH and cracked into CO2 and H2O, so that the quality of effluent is more stable.
Description
Technical field
The utility model relates to the Waste Water Treatment of the plants such as a kind of pig farm, specifically the Waste Water Treatment of a kind of light-Fenton treatment technology.
Background technology
The pig farm waste water main component of raising pigs comprises pig urine, part pig manure and pig house washing water, and such waste water suspension is many, and stink is large, belong to high organic, high nitrogen, high phosphorus sewage, and the carbon-nitrogen ratio imbalance, especially the content of ammonia nitrogen is very high, and this point is difficulty and the key point that breeding wastewater is processed.The Process for Treatment of Swine Wastewater method has following several method at present: first, anaerobic biological treatment: can effectively remove COD and suspended solids in the waste water of raising pigs, and the methane gas of acquisition stable yield, although the water outlet after anaerobic treatment can be used for agricultural irrigation, but the ammonia nitrogen that anaerobic digestion produces, smell and the pathogenic agent in water of water have not only reduced environmental quality, and have threatened the mankind's health.The second, aerobe is processed: mainly adopt activated sludge process, the effect of this method removal COD and suspended solids is better, but the effect of removal nitrogen, phosphorus is poor, and the residence time is long, and is all very high to dissolved oxygen requirement and nutraceutical demand.The 3rd, the anaerobic-aerobic biological treatment: in the rational situation of operation, can reach respectively the purpose of denitrogenation and dephosphorization, but occupation area of equipment is large, management expectancy is high, is not suitable for some money areas in short supply, soil.The 4th, Ecological Disposal: artificial swamp is processed the waste water of raising pigs, and can effectively remove organic matter, but unsatisfactory to the removal effect of inorganic nitrogen.
By the organic process quilt of photocatalysis Decomposition, generally apply to all respects that chemical industry is relevant in recent years, photocatalyst is under the irradiation of light, can produce similar photosynthetic light-catalyzed reaction, produce oxidation capacity extremely strong free hydroxy and active oxygen, its principle is roughly as follows: at first, ozone produces free hydroxyl group under photolysis, then with other material generation photochemical reactions, according to Grotthus-Draper and Einstein-Stark law, under photoresponse, after the molecular absorption photon, can produce the transfer transport phenomenon, impel molecule activation.Electronics is excited to the track on high energy rank by the low energy rank, as electronic orbit, just be positioned on chemical bond, and luminous energy can interrupt chemical bond when enough, and produce free radical reaction.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of waste water treatment system for nursery, utilizes the decolouring oxidation to waste water, and outlet effect is good, and light utilization efficiency is high, and cost is lower.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of waste water treatment system for nursery, comprise water tank, described system also comprises doser, transferpump, photocatalyst, dissolving, ozonizer and gas-liquid mixing pump, doser, water tank, transferpump, photocatalyst, dissolving, gas-liquid mixing pump and ozonizer connect successively by pipeline, and gas-liquid mixing pump also is connected with photocatalyst by pipeline.
Between described transferpump and photocatalyst, also be provided with strainer, transferpump connects by pipe-and-filter, and strainer is connected with photocatalyst by pipeline.
Described doser comprises respectively independently sulphuric acid tank and ferrous tank, and this sulphuric acid tank is connected with water tank by pipeline respectively with ferrous tank.
Described treatment system also comprises that pure water supplements tank, and this pure water supplements tank and is connected with the connecting tube between transferpump and strainer and photocatalyst by pipeline.
The utility model adopts photocatalytic system-ozone combination, using ozone as oxygenant, under thermal effect, produce OH, utilize its strong oxidizing property attack organism, and make it be cracked into CO2 and H2O, make the effluent quality of whole system more stable, and can utilize fully photon, cost is lower.
The accompanying drawing explanation
Accompanying drawing 1 is the utility model catenation principle schematic diagram.
Embodiment
For the ease of those skilled in the art's understanding, the utility model will be further described below in conjunction with accompanying drawing.
As 1 method of accompanying drawing, this practicality has disclosed the treatment system of a kind of plant waste water, as pig farm etc.This treatment system comprises a kind of waste water treatment system for nursery, comprise water tank, and doser 2, transferpump 3, photocatalyst, dissolving, ozonizer and gas-liquid mixing pump 5, doser 2, water tank, transferpump 3, photocatalyst, dissolving, gas-liquid mixing pump 5 and ozonizer connect successively by pipeline, and gas-liquid mixing pump 5 also is connected with photocatalyst by pipeline.Between transferpump 3 and photocatalyst, also be provided with strainer, transferpump 3 connects by pipe-and-filter, and strainer is connected with photocatalyst by pipeline.Doser comprises respectively independently sulphuric acid tank and ferrous tank, and this sulphuric acid tank is connected with water tank by pipeline respectively with ferrous tank.
In addition, treatment system also comprises that pure water supplements tank 1, and this pure water supplements tank 1 and is connected with the connecting tube between transferpump 3 and strainer and photocatalyst by pipeline.
In water tank, be pending waste water, can be by adding some medicaments, as sulfuric acid and ferrous iron, carry out chemical reaction, be convenient to subsequent disposal, then through transferpump, being delivered to strainer filters, the impurity of some larger particles of filtering, waste water enters in photocatalyst again, ozonizer produces ozone and is delivered in gas-liquid mixing pump simultaneously, pending waste water in photocatalyst also enters in gas-liquid mixing pump and is mixed and enters dissolving with the ozone gas pressurization, and ozone gas fully is dissolved in waste water.Then be expelled in photocatalyst, using ozone as oxygenant, under thermal effect, produce OH, utilize its strong oxidizing property attack organism, and make it be cracked into CO2 and H2O, thereby produce the clear water of recycle again.By utilizing light-Fenton treatment technology, effectively improve effluent quality.
What the equipment such as the photocatalyst in the utility model and strainer used is existing known products, therefore its structure is not repeated in detail.
