Abstract
The invention discloses a high-efficiency purification system of papermaking sewage, which mainly comprises four parts, i.e. an integrated processor 1, a sludge accumulation condenser 2, a separation purifier 3 and a prefilter 4. The high-efficiency purification system also comprises auxiliary electrical appliances for sewage purification, such as a sewage pump, a motor, a pharmaceutical mixer, an electric valve, a water level switch and the like. The four sewage purification devices are main body parts of the whole high-efficiency purification system, are mainly communicated through sewage pipelines, and can finally achieve the purpose of rapid sewage separation and purification through sequential separation of passing sewage. The structure is characterized in that the sludge accumulation condenser 2 and the separation purifier 3 are closed low-pressure tanks (wherein the tank bodies are made of steel plate, stainless steel plate or glass fiber reinforced plastics). Due to the combination of the high-quality active ore filtering medium and the automatic program-controlled operation of the electrical appliances, the invention has the advantages of small size, small occupied area, high purification speed, high efficiency and the like. Moreover, the invention reasonably combines the high technology of physical and chemical principles and the special active ore filtering medium, thereby further improving the sewage separation and purification.
Description
Technical field:
Patent of the present invention relates to a kind of Sewage treatment systems equipment, relates in particular to a kind of high-level efficiency cleaning treatment system that paper waste is decomposed, decolours and purify.
Background technology:
Papermaking enterprise mainly adopts medicament to add biochemical many ponds precipitation, aeration filtering method to the treatment process of processing wastewater at present.Be that biochemistry is progressively precipitated in a plurality of ponds, its shortcoming is to take up an area of greatly, and filtering velocity is slow, and one-time investment is big, later stage running cost height (electricity charge+medicament expense+labour cost).Increased the weight of enterprise's production cost.
Summary of the invention:
The purpose of patent of the present invention is to provide the advanced technology resource of the efficient purification and decoloration of a kind of paper waste, to improve papermaking enterprise the purification and decoloration of processing wastewater is handled, and the investment cost and the working cost of the wastewater treatment of reduction papermaking enterprise, energy-saving and emission-reduction, water reuse in accomplishing reduces pollution of waterhead.
The purpose of the art of this patent is achieved in that described high-efficiency purification system of papermaking sewage is mainly by comprehensive treating process device 1, mud coacervation device 2, separation purifier 3, primary filter 4 four major parts and sump pump 24,17, mixing tank 5, coacervation chamber 6, separator for mud and water 7, motorized valve 8, active ore filtering 9, inspection port 10, vent valve 11, explosive box 12, agitator 13, stored program controlled 14, electro connecting pressure gauge 15, water level switch 16, groove 18 falls into water, the waste residue filter is sent and is with 19, cylinder screen cloth 20, center rising pipe 21, screen cloth power wheel 22, screen cloth motor 23, water receiving bucket 25, conveying belt motor 26, sleeve 27 formations such as grade.Solid-liquid separation technique adopts the materialization principle, and its constructional feature is: filtration and separation techniques adopts multi-level the decomposition, is provided with the filter of cylinder screen cloth 20 and waste residue and send and be with 19 in primary filter 4, the useless wadding of the paper pulp in the waste water can be separated and discharge.A soup mixing tank 5 is set in comprehensive treating process device 1, quickens the mixing velocity of sewage and flocculation agent and the pH value of adjustment sewage.In mud coacervation device 2, device for separating mud and water 7 is set, makes mud slurry and water sepn and reach decolorizing effect, sp act ore in sand form filtering layer 9 is set in separation purifier 3, improve the effect of damming of mud, thereby to best purifying water effect.
The purpose of patent of the present invention can also realize by following technological method: enter the waste residue filter after the drum strainer 20 that is provided with in the described primary filter 4 separates the waste paper wadding and send and be with on 19 in rotation.The waste residue filter send band that paper waste is discharged.Device for separating mud and water 7 its characteristics that are provided with in the described mud coacervation device 2 are: cut mud and do not intercept water, and 80% the mud concentrated solution of damming, and regularly enter sludge sump.Five motorized valves 8 installing on the described separation purifier 3, its characteristics can in time be regulated the purification blowdown automatically according to the situation of cleaner filtering layer contamination and be handled, and reach the water purification purpose.The compact overall structure of patent of the present invention is reasonable, thereby reaches final decontamination effect improving.
Description of drawings:
Fig. 1, for the structural representation of patent of the present invention.
Embodiment:
Below in conjunction with accompanying drawing patent of the present invention is elaborated:
As Fig. 1, shown in, patent of the present invention is made up of comprehensive treating process device 1, mud coacervation device 2, separation purifier 3 and primary filter 4 four most and corresponding pipelines, valve member and electric controller annex.Comprise in the comprehensive treating process device 1: sewage vacuum primingpump 17, electro connecting pressure gauge 15, water level switch 16, automatically controlled device 14, explosive box 12, agitator 13, mixing tank 5 etc.Comprise in the mud coacervation device 2: coacervation chamber 6, separator for mud and water 7, vent valve 11, blowdown motorized valve 8 etc.Comprise five cover motorized valves 8, inspection port 10, vent valve 11, active ore filtering 9, water distributor etc. in the separation purifier 3.Comprise sump pump 24 in the primary filter 4, the groove 18 that falls into water, waste residue filter send be with 19, cylinder screen cloth 20, center rising pipe 21, screen cloth power wheel 22, screen cloth motor 23, water receiving bucket 25, filter belt conveying motor 26 and sleeve 27.Water level switch 16 is a float-ball type, float in the sewage lagoon, after the water level switch conducting, sewage vacuum primingpump 24 is sent paper waste into cylinder screen cloth 20, the useless wadding of isolated paper pulp enters the waste residue filter and send band, muddy water is sent into soup mixing tank pipeline 5 again through sump pump 17, at the same time, flocculation agent soup in the explosive box 12 enters mixing tank 5 through thrust-augmenting nozzle, because the special construction of mixing tank makes sewage and medicament mix in moment, when mixed sewage enters coacervation chamber 6 in the mud coacervation device 2, the most of polymerization of mud, sieving through separator for mud and water 7, after damming, 80% thick slurry regularly enters sludge sump by wash water valve 8,20% the mud of slipping through the net enters separation purifier 3 with current, active ore in sand form filtering layer 9 in the separation purifier is owing to have extremely strong sludge absorption power and resistance, scintilla mud is finally all dammed in cleaner, when the mud molecular weight increases, pressure difference in the cleaner raises, when pressure difference reaches set(ting)value, electro connecting pressure gauge 15 conductings, the short circuit signal impels motorized valve 8 to enter the blowdown cleaning automatically according to the programming design requirements, thickened sludge water in the cleaner is entered sludge sump, and the clean water after purifying then enters the clean water basin regeneration.To purifying waste water, the whole service process only needs about five minutes, is efficient purifying system from sewage.
