Utilize electric flocculation apparatus to carry out pre-treatment to water-borne coatings waste water, compared with traditional method, do not need to add a large amount of medicament, reduce working cost.In reaction process, iron pole plate can lose electronics and separate out iron ion, finally can with the precipitation of hydroxide form of iron ion and the coprecipitated precipitation of some organic pollutants.Fe (OH)
2, Fe (OH)
3for excellent flocculation agent, only need to add a small amount of medicament to accelerate the reaction times, save a large amount of coagulated agent.Be equivalent to carry out a step coagulating kinetics to waste water, pollutent is separated from water body, effectively can remove the grease in waste water, phosphoric acid salt and the various noxious pollutant such as COD, SS and colourity.And the electricity flocculation coagulation sedimentation method that the sludge quantity that produces is more traditional when processing water-borne coatings waste water will lack, and press filtration performance is better.Simultaneously electric flocculation apparatus also have not high to power requirement, operational safety, level of automation are high, treatment effect good, the advantage such as stable.Organic pollutant is resolved into small organic molecule by redox reaction by electricity flocculation apparatus, can improve the biodegradability of waste water, provide the B/C of waste water, for subsequent biochemical process is given security.
Described pump water inlet pipe is also other to be connected to clear water pipe and to clean electric flocculator to utilize clear water.Utilize the automatic switchover of controller to intake, electric flocculation apparatus self-stip can be realized, ensure that equipment can long-time continuous stable run.
Preferably, for ensureing water inlet evenly, described electricity flocculation water inlet pipe to extend to below reaction polar plate and on body, is provided with multiple ostium excurrens to realize water distribution uniformity.The water outlet of the liquid feeding pump simultaneously also and be connected to be communicated to pH regulator pond feed liquor return line to realize the convenient adjustable of intake pressure.
Anaerobic pond 22, anoxic pond 23, contact-oxidation pool 24 and second pond 25 that described biochemical treatment apparatus comprises and arranges in the mode that overflow is communicated with, the clean water overflow of described second pond enters intermediate water tank, in contact-oxidation pool, filler is elastic solid filler, is provided with aeration tube bottom described filler.Anaerobic pond need build the environment of anaerobism, and its dissolved oxygen is about zero, is generally less than 0.1mg/L, is beneficial to like this and detests foster microorganism growth.By anaerobion, organism is hydrolyzed acidification, the organism in waste water is carried out open loop chain rupture, is more conducive to aerobic microbiological and carries out a point desorption.PolyP bacteria simultaneously in backflow mixed liquor discharges phosphate radical with this understanding.
Waste water gravity flow after anaerobic treatment enters bottom anoxic pond, and from bottom to top by anoxic pond, anoxic pond builds the environment of anoxic, and its dissolved oxygen is being less than 0.5mg/L, as at 0.3mg/L-0.5mg/L, is beneficial to lack and supports microorganism growth.Its effect utilizes anoxic microorganism adsorption and degradation of organic substances.Nitrite nitrogen and nitrate nitrogen are generated under the effect of denitrifying bacteria nitrogen release.
Contact-oxidation pool has the advantage of activated sludge process and biomembrance process concurrently, filling filler in pond, the whole filler of waste water submergence of oxygenation, and flows through filler with certain flow velocity, and in contact-oxidation pool, dissolved oxygen is 2-4mg/L.Filler is covered with microbial film, waste water and biofilm contact, on microbial film the metabolic function of microorganism effect under, Organic Pollutants in Wastewater is removed, and waste water is purified.In contact-oxidation pool, Institute of Micro-biology is aerobic is supplied by blast aeration, after biofilm development to certain thickness, the microbes of filler wall carries out anaerobic metabolism because of anoxic, the souring that the gas produced and aeration are formed can cause biomembranous coming off, and promote the growth of true tumor film, now, the microbial film come off will flow out outside pond with water outlet.
The effect of second pond mainly makes mud-water separation, and what make Aerobic Pond goes out clarification of water, is carried out concentrating and refluxing by the aerobic activated sludge in water simultaneously.
By the alternate treatment to waste water of anerobe and aerobic bacteria, major part is carried out to organic pollutants and removes, other pollutents such as ammonia nitrogen, phosphorus are removed simultaneously.
Preferably, for improving bulk treatment effect, also comprise sludge treatment subsystem, it comprises collecting described primary sedimentation basin and second-level settling pond second sludge sump 15, mud in the second described sludge sump and the first sludge sump is delivered to anaerobic pond and anoxic pond and sludge agitator tank 16 through sludge pump, pressure filter 17 is transported to, the sludge bulking outward transport of generation, the press filtration water backflow equalizing tank of generation or sewage collecting pool after mud mixing in sludge agitator tank.
Also comprise the 3rd sludge sump 18 of the mud of discharging in order to temporary Aerobic Pond, in the 3rd described sludge sump, be provided with the submersible sewage pump that the 3rd sludge pipe is communicated to sludge agitator tank.Utilize the buffer memory of the 3rd sludge sump, the convenience that in phase anoxic pond and anaerobic pond, mud adds can be ensured.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
