Technical field
The utility model relates to a kind of treatment facility of waste water, relates in particular to a kind of treatment facility that contains high organophosphorus and high-concentration ammonia nitrogenous wastewater.
Background technology
The common pesticides that organophosphate poisoning belongs to organic phosphates comprises Glyphosate 62 IPA Salt, phorate (3911), Systox (1059), thiophos (1605), SD-1750, Rogor, Trichlorphon, Malathion (4049) etc.General reason of poisoning is direct cutaneous contact, respiratory tract suction and wrongly takes, misapplies.Through skin absorption, make slow progress; Per os and respiratory tract suck, and progress fast.Organophosphorus mainly is the inhibition to E.C. 3.1.1.7 to people and animals' toxicity, causes that vagusstoff accumulates, and cholinergic nerve is received continue impulsion, causes the depleted symptoms such as a series of muscarinic, nicotine appearance and cns in excited earlier back; Severe patient can be because of stupor and respiratory insufficiency death, and organophosphorus insecticides mostly is oily or crystalloid, and color and luster, is had volatility slightly, and has garlicky to brown by yellowish.Except that Trichlorphon, generally be insoluble in water, be not soluble in multiple organic solvent, easy decomposition failure under alkaline condition.Formulation commonly used has emulsion, finish and pulvis etc.R and R ' are alkyl, aryl, azanol base or other genes, and X is alkoxyl group, propyl group or other substituting groups, and Y is oxygen or sulphur.
Excessive ammonia nitrogen enters water body will cause body eutrophication, reduce the water body ornamental value, and the nitrate salt of oxidized generation and nitrite also can influence hydrobiont even human beings'health.Therefore, denitrogenation of waste water is handled and is got more and more people's extensive concerning.At present, main denitrogenation method has biological nitration reaction, break point chlorination, gas stripping and ion exchange method etc.The ammonia nitrogen that digested sludge dehydration liquid, refuse leachate, catalyst manufacturer waste water, meat processing waste water and synthetic ammonia wastewater from chemical industry etc. contain high concentration is (more than the 500mg/L; Even reach several ten thousand mg/L), above method can be because the biological restraining effect of free ammonia nitrogen or cost etc. be former thereby its application is restricted.
In view of high organophosphorus content and high-concentration ammonia nitrogenous wastewater to the high hazardness of humans and animals and to the restraining effect of mikrobe, organophosphorus and the ammonia nitrogen removed in the waste water are the necessary steps for wastewater treatment.
Summary of the invention
The utility model provides a kind of device that removes high organophosphorus nitrogen ammonia waste water to deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
Remove the device of high organophosphorus nitrogen ammonia waste water, comprise modified pond, ligation chamber, modified pond, reaction chamber connects sludge sump; Sludge sump connects clean water basin; Clean water basin connect alkaline hydrolysis still intake pump, and alkaline hydrolysis still intake pump connects HTHP alkaline hydrolysis still, and HTHP alkaline hydrolysis still connects stripping tower.Waste water adds OH-in modified pond, get into the reaction chamber reaction, and in sludge sump, the upper strata clear water of post precipitation gets into clean water basin, is pumped into HTHP alkaline hydrolysis still by alkaline hydrolysis still intake pump again, and the waste water of process HTHP alkaline hydrolysis still is at last by the stripping tower ammonia nitrogen removal.
As preferably, sludge sump is connected through effluent weir with clean water basin, and described sludge sump is provided with stirrer and mud scraper.After waste water got into sludge sump, the sludge settling in the waste water was to the bottom of sludge sump, and the stirring of stirrer drives the inner waste water of sludge sump and is in dynamically, can not cause the deposition caking.Mud scraper scrapes extreme lower position with the mud of bottom settlings.
As preferably, the sludge sump bottom connects the mud transferpump, and the mud transferpump connects water extracter, and water extracter connects reservoir, and reservoir connects filtrate pump, and filtrate pump connects clean water basin.The mud of sludge sump bottom is pumped in the water extracter by the mud transferpump, and the water of deviating from is transported to reservoir, and the top clear water of post precipitation was transported in the clean water basin by filtrate pump in reservoir.The filtration clear water on sludge sump top directly is transported in the clean water basin by effluent weir.
As preferably, the bottom of sludge sump is the inclined-plane.The scarp helps mud scraper the mud of bottom settlings is scraped extreme lower position.
As preferably, HTHP alkaline hydrolysis still is connected with vapour pipe.Vapour pipe is the heating of HTHP alkaline hydrolysis still.
As preferably, stripping tower connects airduct.The airduct of the bottom in the stripping tower is constantly carried air in tower, make inner sewage be in dynamically, and the fan on top connects venting port, and the ammonia in the sewage just can be along with venting port is discharged.
According to the technical scheme of the utility model, device structure is reasonable, can high efficiencyly remove organophosphorus and ammonia nitrogen in the waste water.
