Description
Technical field
The utility model relates to a kind of sewage disposal device, especially a kind of wet desulphurization buck reclaim equiment.
Background technology
At present, have following several substantially for the common method of wet desulphurization buck manipulation of regeneration: the one, semi-underground buck settling bowl natural sedimentation; The 2nd, ramps Precipitation method; The 3rd, dosing coagulation+seperator of ash and water facture.Though first kind of treatment process technical process is simple, floor space is big, and poor processing effect and instability, water quality treatment are difficult to reach the reuse requirement, and at present, this treatment process progressively is eliminated; Ramps Precipitation method is that buck adds behind the liming to be promoted by sump pump and enters inclined-plate clarifying basin and carry out solid-liquid separation, this method have investment lower, take up an area of better advantages such as (SS are about 100mg/l) of less, treatment effect, but it is still higher to go out water suspension; The third facture: the seperator of ash and water that adopts is by under sloping plate deposition and the sand filter at present, last composition, buck adds liming and coagulating agent carries out entering seperator of ash and water by the sump pump lifting behind the coagulating, carry out the solid-liquid separation of first post precipitation quartz sand filtration, after this equipment moves to certain hour, need carry out back flushing, by backwash pump backwashing water is promoted and to carry out back flushing from bottom to top, the back flushing water yield is generally 10L/m2.s, good (the SS≤10mg/l) of this facture treatment effect, floor space is little, but this art breading cost height (needs to add coagulating agent, strengthened the dosage of liming, the back flushing water yield is big) drawbacks limit promoting the use of of this equipment, this is the shortcoming of prior art.
Summary of the invention
The purpose of this utility model provides that a kind of treatment effect is good, floor space is little, processing cost and the low wet desulphurization buck manipulation of regeneration equipment of equipment manufacturing cost.
The purpose of this utility model is achieved through the following technical solutions: this equipment is combined by four identical tube settling+light filter material filtration reactors, each reactor comprises tube settling district, mixing zone, light filter material filtrating area, clear water zone from bottom to up, clear water zone interconnects, clear water zone is following vertically to be divided into four identical tube settling+light filter material filtration reactors by two dividing plates, before and after in the middle of the clear water zone, be furnished with into and out of tank, inlet flume down, effluent trough is last.Buck enters respectively in four reactors by pipeline after entering inlet flume, reuse behind the water of the clear water zone inflow effluent trough.
The utility model is owing to adopt technique scheme, it has the following advantages: (1) buck is after tube settling and light filter material filtration, and effluent quality is good, and reuse water SS is stabilized in below the 10mg/l, really accomplish buck whole closed circulation after manipulation of regeneration, do not efflux; (2) equipment manufacturing cost and processing cost are low: the low SS of reuse water makes the small-bore possibility that becomes of shower nozzle, the atomizing and the reaction effect of sweetener have been improved greatly, reduced quantity of circulating water (can reduce quantity of circulating water more than 25%), reduced medicament usage quantity (can reduce the medicament usage quantity more than 10%), this equipment does not add coagulating agent and carries out coagulating, thereby can not adding because of coagulating agent, and the dosage of increase liming, adopt light filter material to filter, the back flushing water yield is few, and the back flushing water yield is 5L/m2.s, during the equipment back flushing, the water flow by gravity of clear water zone carries out back flushing from top to bottom, and above-mentioned measure has reduced the cost and the processing cost of equipment; (3) wearing and tearing of water circulating pump and sweetener have been alleviated, the work-ing life of having improved relevant device; (4) floor space is little.
