Technical background
MBR-membrane technology apparatus for treating sewage is that collection sewage disposal and middle water reuse are the intelligent treating apparatus of one, this equipment main feature is with activated sludge process and membrane technology perfect adaptation, secondary sedimentation tank with in the membrane module replacement traditional wastewater biological treatment thoroughly separates muddy water under the efficient crown_interception of membrane module; Because the effect of the high-concentration activated sludge in the membrane filtration district, improved biochemical reaction rate, reduce excess sludge production, solved the ubiquitous effluent quality instability of traditional wastewater biological treatment, floor space is big, operation maintenance is complicated, outstanding problems such as sludge bulking easily take place.
MBR introduces biological treatment of waste water system with membrane separation technique, utilizes membrane separation technique and bioreaction technology advantage separately, a kind of efficient water treatment system of developing.It has advantages such as the space of occupation of land is little, Separation of Solid and Liquid rate height, activated sludge concentration height, treatment effeciency height, effluent quality is good, sludge yield is low, operational management is simple.But it also exists cost of equipment high slightly, and the film ratio is easier to pollute, and the service life of film, weak point waited the problem that still need solve.
Summary of the invention
The purpose of this utility model is intended to overcome the defective of prior art, provides that a kind of floor space is little, cleaning performance good, safeguard simple flat plate film purging system.
Flat sheet membrane purging system described in the utility model, mainly constitute by filtered water tank, U type aeration tube and product water, detergent line, filtered water tank is positioned at the top of system, in its bottom the cleaning water inlet is arranged, by pipe fitting with produce water, detergent line is connected and forms the loop of circulating, the loop is provided with wash-out valve and inlet valve, and U type aeration tube is positioned at the outer bottom of flat sheet membrane.
Flat sheet membrane purging system described in the utility model is connected with the cleaning water inlet in the bottom of filtered water tank, is provided with overfall, delivery port, air inlet in the filtered water tank.In the filtered water tank liquid level of cleaning fluid to film collector pipe distance less than 100cm.In product water, detergent line, be connected with the product water pump.On the pipeline that produces between water, detergent line and the filtered water tank water inlet, be connected with flowmeter, sterilizer, water meter.
The utility model is mainly by the filtered water tank that can doublely do cleaning case, U type aeration tube three parts of producing water, detergent line and being installed in the flat sheet membrane bottom are formed, utilize the filtered water tank of its upper side, increase by one in the bottom and clean water inlet, utilize that pipe fitting and water producing pipe are short out to be connect, form closed circuit, form a complete product water, detergent line system; And a wash-out valve, an inlet valve be set on the loop; By clean, the unlatching of inlet valve or close, realize two kinds of functions that control is respectively produced water, cleaned the flat sheet membrane filter membrane; The flat sheet membrane outside is washed by the U type aeration tube that is arranged on the bottom.Improvement through pipeline, make filtered water tank have both the function of dosing tank and cleaning case, product water, detergent line unite two into one, and have realized contaminated flat sheet membrane is regularly cleaned, look the pollution level of flat sheet membrane filter membrane during cleaning, can select dosing to clean or directly clean with clear water.The utility model has been simplified the operation of whole cleaning process, makes the equipment appearance layout more reasonable, attractive in appearance, has prolonged the service life of flat sheet membrane, has guaranteed the aquifer yield and the water quality of equipment.
Description of drawings
Fig. 1 is a utility model flat sheet membrane purging system structural representation.
Fig. 2 is a utility model flat sheet membrane purging system structural representation.
Among the figure, 1-produces water pump, 2-inlet valve, 3-wash-out valve, 4-overfall, 5-filtered water tank, 6-produces water, detergent line, 7-flat sheet membrane part, 8-U type aeration tube, 9-flowmeter, 10-sterilizer, the 11-water meter, 12-filtered water tank water inlet, 13-air inlet, 14-film collector pipe, 15-delivery port.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, but is not limited to embodiment.
Embodiment 1
As depicted in figs. 1 and 2; Si Napu (SINAP) flat sheet membrane part 7 vertically is placed in the aerobic reaction pond; active sludge intermixture passes through diaphragm; membrane filtration after filtration; by producing water, detergent line 6; by producing water pump 1 sucking-off from flat sheet membrane part 7, and through sterilizer 10, flow 9, water meter 11, enter in the filtered water tank 5, by overfall 4 from delivery port 15 outflows.Because the SINAP flat sheet membrane is different with the structure of hollow-fibre membrane; the filter membrane outer surface has layer protecting film protection; bigger scouring force can be born in the outside; and bigger scouring force can not be born in inside; otherwise will damage filter membrane and outside diaphragm, cause filter membrane directly to contact with active sludge intermixture.While is very easily caused the damage and the damage of filter membrane under the effect of the air scour power of U aeration tube 8, flat sheet membrane is scrapped, and can't realize filtration, directly influences the operation of entire equipment.
For avoiding because of cleaning the excessive filter membrane that damages flat sheet membrane part 7 of hydraulic pressure; In 100cm, the best is about 80cm to the cleaning liquid level to film collector pipe 14 distances in the strict control filtered water tank 5, otherwise will cause damage and damage to filter membrane.Requirement for the cleaning of satisfying filter membrane, we are placed on filtered water tank 5 designs at the top of equipment room, utilize the deadweight of water in the case, freely flow out from the bottom, slowly enter in the filter membrane of flat sheet membrane part 7, from the inside to surface filter membrane is washed, the outside utilizes flat sheet membrane part 7 bottom U type aeration tubes 8 to wash away the flat sheet membrane outer surface, surface contaminants is entered in the membrane cisterna, and post precipitation is discharged by blowoff line, finishes the whole cleaning process to flat sheet membrane.Filtered water tank 5 bottoms are connected with filtered water tank water inlet 12, are provided with overfall 4, delivery port 15, air inlet 13 in the filtered water tank.
The cleaning frequency of filter membrane decides on the filter membrane pollution level, the cleaning frequency of general sanitary sewage be 5~6 months once.When cleaning beginning; At first stop to produce water pump 1, close inlet valve 2; When the filter membrane pollution level is serious, cleaning agent can be added in the filtered water tank 5, ventilation is stirred, and cleaning agent and clear water are mixed; When light, can not add cleaning agent as the film pollution level, need not ventilate and stir; Open wash-out valve 3, water automatic slowly in the filtered water tank 5 is flowed in the flat sheet membrane part 7, wash from inside to outside, the outside utilizes 8 ventilations of flat sheet membrane part 7 bottom U type aeration tubes to carry out flush clean, the dirt that oozes out flat sheet membrane part 7 surfaces is entered in the membrane cisterna, and post precipitation is discharged by blowoff line.After treating the whole emptyings of water of filtered water tank; Close wash-out valve 3, open inlet valve 2, start and produce water pump 1, recover the flat sheet membrane filtering function, equipment enters normal operating conditions, finishes whole cleaning process.
By cleaning, the cleannes and the service life of greatly having improved flat sheet membrane have guaranteed the aquifer yield of equipment and produced water quality, realized the maximization of economic benefits.
