Description
Technical field
This utility model relates to a kind of wastewater zero discharge system, particularly relates to a kind of system processing Nitrogen-and Phosphorus-containing zero discharge of industrial waste water, belongs to environmental protection purifying equipment processing technology field.
Background technology
So-called zero-emission, refer to ad infinitum to reduce pollutant and can source emission until to zero activity.Industrial wastewater " zero-emission " technology is possible not only to be substantially reduced the environmental pressure of sewage discharge, it is also possible to by sewage recycling, reaches high efficient utilization of water resources and reclaims the purpose of solid product.According to " Jiangsu Province's Taihu Lake Basin pollution prevention ordinance " the 45th article, forbid newly-built, renovating and enlarging chemical pulping paper making, process hides, wine brewing, dyestuff, print and dye, electroplate and other discharges are phosphorous, the enterprise of nitrogen pollutant and project；Forbid selling, using phosphorus-containing detergent.
At present, the waste water that a lot of enterprises produce has the advantages that the water yield is little, pollutant levels are high, nitrogen and phosphorus content is high, is increasingly difficult to more and more expensive outside waste water committee.If waste water reuse after treatment, the source of reuse is also problem, needs to reach the highest quality and just can be back to production technology, and the recycle-water after present most of Waste Water Treatments often process does not reaches production technology water requirement.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, this utility model provides a kind of system processing Nitrogen-and Phosphorus-containing zero discharge of industrial waste water, being applicable to the zero discharge of industrial waste water of the nitrogen phosphorus of the little water yield, high concentration, after process, water outlet is far superior to tap water standard.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of system processing Nitrogen-and Phosphorus-containing zero discharge of industrial waste water, including passing sequentially through pipeline and the collecting-tank of elevator pump connection, coagulation overflowing precipitation device, evaporation unit, reverse osmosis unit, reuse pool each other and being back to produce product line；Offer PH adjusting means, flocculant chemicals dosing plant between above described coagulation overflowing precipitation device and help solidifying chemicals dosing plant；It is also connected with crystallization apparatus on described evaporation unit.
Improve further as this utility model, the described main heater of evaporation unit, vaporizer and condenser composition.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
A kind of system processing Nitrogen-and Phosphorus-containing zero discharge of industrial waste water of the present utility model, produces water water quality quality height, meets water needs more, higher；System process route is compact, takes up an area little；Can reach wastewater zero discharge, there is good environmental benefit.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of the system of process Nitrogen-and Phosphorus-containing zero discharge of industrial waste water of the present utility model；
Wherein: 1, collecting-tank；2, coagulation overflowing precipitation device；3, PH adjusting means；4, flocculant chemicals dosing plant；5, solidifying chemicals dosing plant is helped；6, heater；7, vaporizer；8, condenser；9, evaporation unit；10, crystallization apparatus；11, reverse osmosis unit；12, reuse pool；13, it is back to produce produce line.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Described in the utility model a kind of system processing Nitrogen-and Phosphorus-containing zero discharge of industrial waste water as shown in Figure 1, including passing sequentially through pipeline and the collecting-tank 1 of elevator pump connection, coagulation overflowing precipitation device 2, evaporation unit 9, reverse osmosis unit, reuse pool each other and being back to produce product line；Offer PH adjusting means, flocculant chemicals dosing plant between above described coagulation overflowing precipitation device and help solidifying chemicals dosing plant；It is also connected with crystallization apparatus on described evaporation unit.
Nitrogen phosphorus industrial wastewater is collected by pipeline and is entered collecting-tank 1, have by elevator pump, enter coagulation overflowing precipitation device 2, by PH adjusting means 3, waste water adjusted pH8～8.5, by flocculant chemicals dosing plant 4 with help solidifying chemicals dosing plant 5, waste water is fully carried out coagulation, flocculation reaction；Carrying out preliminary solid-liquid separation through coagulation, waste water after flocculation reaction is good by overflowing precipitation region, supernatant pumps into evaporation unit 9；Evaporation unit 9 is mainly made up of heater 6, vaporizer 7, condenser 8 and auxiliary equipment etc..Waste water passes through rapid steamer evaporative condenser 9, and evaporation produces and crystallizes the outer process of committee after concentrated solution entrance crystallization apparatus 10 solidification；Vaporizer produces water and pumps into reverse osmosis unit 11, by the filtration of film, produces water and enters reuse pool 12, is back to produce and produces line 13.
Vaporizer 7 has efficient Waste water concentrating ability, waste water is sucked by vacuum, measured by effusion meter, after being heated to boiling in the pipe of heater, part water vapor, make heat energy be converted into the kinetic energy moved upward, simultaneously because it is poor to create severe between the feed liquid of not boiling in liquid-vapor mixture and circulation pipe in adding heat pipe, creating the Natural Circulation of feed liquid, the more, its circulation rate is the biggest for feed liquid received heat.Owing to evaporating under vacuum, the evaporating temperature of its feed liquid can be with temperature control at low-temperature evaporation, evaporating temperature controls tangentially to enter vaporization chamber together with liquid mixing at about the 60 DEG C gases evaporated, rise through vaporization chamber top after carrying out preliminary vapor-liquid separation, enter condenser, reclaimed by liquid bucket.
Counter-infiltration system is a kind of physical separating process, and under certain pressure effect, part clear water and small-molecule substance form clear liquid, remaining material and water through film and form concentrated solution；Counter-infiltration system can carry out effectively catching to all of suspended contaminant and major part multivalent salts ion；In the case of Effects of Water Quality is preferable, producing Water Sproading rate is more than 75%, and the product water water quality of counter-infiltration system can stably reach and produce the requirement producing line water supply standard.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, within the scope of all falling within this utility model rights protection.
