Description
Technical field
The utility model relates to a kind of wastewater treatment equipment, especially a kind of throwing device of the biological wastewater treatment organic nutrient aganic nutrient agent with sensor.
Background technology
At present, the industries such as medicine, chemical industry produce a large amount of trade effluent, usually need to carry out biochemical treatment.Often have bio-toxicity in these trade effluents or contain hard-degraded substance, cause biochemical treatment efficiency lower, water outlet can not reach waste water recycling or emission standard.Add nutrition agent and can improve microorganism active, effectively improve biochemical treatment of industrial wastewater efficiency.
On market, the structure of the throwing device of existing biological wastewater treatment organic nutrient aganic nutrient agent arranges at origin or beginning place, aeration tank to add parts, directly can add nutrition agent in aeration tank origin or beginning like this.This throwing device can not give full play to the beneficial effect of nutrition agent, causes the waste of medicament expense.Because nutrition agent promotes biochemical efficiency mainly through two aspect effects: the first, supplement nitrogen, phosphorus and trace element, for microorganism balancedly supplies nutrition, to improve its metabolic activity; The second, carbon source of easily degrading is provided, by the cometabolism effect of microorganism, decomposes part hardly degraded organic substance.Give full play to second aspect effect, in water inlet, original easy degraded carbon source must add nutrition agent again after substantially exhausting, otherwise former water and the easy degraded carbon source in nutrition agent synchronously exhaust, and the decomposition of cometabolism effect to difficult degradation carbon source in former water can not occur.So existing throwing device on market, does not affect first aspect and play a role, but second aspect performance can be limited.
Summary of the invention
The utility model for above weak point, provide a kind of can further enriched nutrient to the throwing device of the biological wastewater treatment organic nutrient aganic nutrient agent of the castering action of biochemical treatment efficiency.
The utility model solve its technical problem adopt technical scheme to be: the utility model is the water treatment structure of a set of solid: organic nutrient aganic nutrient agent storage tank adds pipeline by nutrition agent and is connected with the import of volume pump, metering pump outlet connects nutrition agent and adds pipeline, and the end that nutrition agent adds pipeline gos deep in aeration tank; Dissolved oxygen sensor is placed in aeration tank, and dissolved oxygen sensor is connected with housing, and housing is connected with volume pump.
Described nutrition agent adds line end and is arranged on long position, distance feed-water end 1/3 pond, aeration tank.
Described dissolved oxygen sensor is arranged on long position, distance feed-water end 2/3 pond, aeration tank.
Principle of the present utility model is as follows: in waste water aerobic biochemical treatment, and easily degraded carbon source can complete decomposition within a short period of time, is usually no more than 1/3 of total aeration time.Make full use of nutrition agent for making microorganism and carry out cometabolism, should arrange again after 1/3 position of aeration zone feed-water end and add pipeline and add nutrition agent.Wastewater biochemical process often carries the function being removed ammonia nitrogen by nitrification, and nitrification just can must be carried out after substantially exhausting by easily biodegradable organics in water.In the region that aeration section feed-water end 2/3 is later, the easy degraded carbon source that nutrition agent provides exhausts substantially, and dissolved oxygen rises, and can be used as nitration reaction district.
Compared to the prior art the throwing device of a kind of biological wastewater treatment organic nutrient aganic nutrient agent of the present utility model, has following characteristics: one, according to the aeration tank end dissolved oxygen concentration that sensor records, and accurately controls the dosage of organic nutrient aganic nutrient agent, avoids waste; Two, in waste water, original easy degraded carbon source adds organic nutrient aganic nutrient agent after exhausting again, improves the utilising efficiency of organic nutrient aganic nutrient agent; Three, the biochemical clearance of trade effluent COD can be improved further.Use the utility model to control nutrition agent to add, trade effluent COD clearance can be improved further.Different according to influent quality, COD clearance can improve about 3% ~ 10%.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Accompanying drawing 1 is the structural representation of the throwing device of biological wastewater treatment organic nutrient aganic nutrient agent.
In figure: 1, organic nutrient aganic nutrient agent storage tank, 2, housing, 3, volume pump, 4, nutrition agent adds pipeline, 5, dissolved oxygen sensor, 6, aeration tank.
Embodiment
Be described in detail below with reference to the throwing device of Figure of description to a kind of biological wastewater treatment organic nutrient aganic nutrient agent.
The throwing device structure of a kind of biological wastewater treatment organic nutrient aganic nutrient agent of the present utility model is: organic nutrient aganic nutrient agent storage tank 1 adds pipeline 4 by nutrition agent and is connected with the import of volume pump 3, the outlet of volume pump 3 connects nutrition agent and adds pipeline 4, and the end that nutrition agent adds pipeline 4 gos deep in aeration tank 6; Dissolved oxygen sensor 5 is placed in aeration tank 6, and dissolved oxygen sensor 5 is connected with housing 2, and housing 2 is connected with volume pump 3.
Described nutrition agent adds pipeline 4 end and is arranged on the position long apart from feed-water end 1/3 pond, aeration tank 6.
Described dissolved oxygen sensor 5 is arranged on the position long apart from feed-water end 2/3 pond, aeration tank 6, for measuring dissolved oxygen concentration.
Described organic nutrient aganic nutrient agent storage tank 1 material is glass reinforced plastic, has good corrosion resistance nature.Built-in agitator, can keep organic nutrient aganic nutrient agent homogeneous.
In use, volume pump 3 aspirates nutrition agent to the utility model from organic nutrient aganic nutrient agent storage tank 1, adds pipeline 4 be evenly added in aeration tank 6 by nutrition agent.Dissolved oxygen concentration data in aeration tank are transferred to housing 2 by dissolved oxygen sensor 5, and in housing 2, setting dissolved oxygen concentration lower limit is 2 ~ 3mg/L, and the upper limit is 5mg/L.The dissolved oxygen concentration recorded when the electrode of dissolved oxygen sensor 5 is prescribed a time limit higher than upper, and housing 2 controls volume pump 3 and opens; The dissolved oxygen concentration recorded when the electrode of dissolved oxygen sensor 5 is prescribed a time limit lower than lower, and housing 2 controls volume pump 3 and closes down.
It is few that the utility model nutrition agent adds dosage, and improve significantly microorganism active, biochemical treatment efficiency is improved, and processing costs is low.
