Abstract
The invention discloses a scraping method and device suitable for float sludge of a radial-flow secondary sedimentation tank for leather sewage. The method includes the steps that a slag collecting hopper is arranged in the secondary sedimentation tank so that the slag collecting hopper can rotate, the float sludge in the secondary sedimentation tank overflows to enter the slag collecting hopper, the float sludge in the slag collecting hopper is conveyed to a slag collecting tank, and the float sludge in the slag collecting tank is discharged to a sludge thickening tank or flows back to a biochemical system so as to replenish the loss sludge. The device comprises a water inlet cylinder, a support, a flow guide cylinder, the slag collecting hopper, a sludge scraping board, a working bridge and a float drag discharging pipe. The flow guide cylinder is arranged on the water inlet cylinder in a sleeving mode. The slag collecting tank is arranged on the outer side of the flow guide cylinder. The support is arranged on the water inlet cylinder. The working bridge is connected to the support, and a rotating wheel on the outer side of the working bridge is connected with a driving mechanism. The sludge scraping board is connected below the working bridge through a sludge scraping rack, and the slag collecting hopper is arranged on the upper portion of the sludge scraping rack. By the adoption of the scraping method and device, the float sludge can be discharged stably and effectively, even though a large amount of float sludge exists, it is still guaranteed that the float sludge can be discharged in time, and therefore the water outlet effect of the secondary sedimentation tank is guaranteed.
Description
Technical field
The present invention relates to a kind of scraping methods and device of the mud scum for leather waste water Radial Flow Secondary Sedimentation Tank, belong to and scrape Fender slag machine technology field.
Background technology
Because leather waste water has high grease, high ammonia nitrogen, is rich in surfactant, in the second pond of process leather waste water, often Mud up-floating phenomenon occurs, face, whole pond is covered with the mud scum of thick 20-100mm, is rich in grease in mud scum, in conjunction with as a whole.
Traditional Fender slag machine of scraping major function be on the one hand by the sludge scraping at the bottom of Radial Flow Secondary Sedimentation Tank pond to the collection mud pit being positioned at second pond center, on the one hand the scum silica frost floated on the water surface is collected into scum silica frost groove, the mud be scraped and scum silica frost by transport pump to sludge treating system.It is fairly simple that it scrapes slag system, is usually made up of two pieces of scum boards and a scum silica frost groove, and under the influence of centrifugal force, scum silica frost is scraped in scum silica frost groove.When scum silica frost is less, traditional scrape scraping slag effect and can meeting the demands of mud slag remover.For the mud scum of leather waste water second pond, because mud scum is in conjunction with as a whole, and amount is larger, must artificial assistance be dragged for by mud scum in scum silica frost groove, labour intensity be large, and manually drags in slag process, disturbance second pond surface current, affect sedimentation effect, cause water outlet not up to standard, if discharge mud scum not in time, mud scum will run off with water outlet, while causing water outlet not up to standard, activated Sludge System sludge quantity constantly reduces, thus causes whole sewage disposal system to paralyse.
Summary of the invention
The present invention is directed to the problem that a large amount of mud scums in process leather waste water Radial Flow Secondary Sedimentation Tank cannot be discharged in time, a kind of scraping methods being applicable to leather waste water Radial Flow Secondary Sedimentation Tank mud scum can discharging mud scum is in time provided, a kind of device realizing the method is provided simultaneously.
The scraping methods being applicable to leather waste water Radial Flow Secondary Sedimentation Tank mud scum of the present invention, is:
In second pond, arrange a slag gathering hopper, slag gathering hopper, with the gradient being not less than 1%, makes the top of slag gathering hopper with water surface hold the line in second pond, or is higher or lower than the water surface and is not more than 5mm, and slag gathering hopper is rotated, and the mud scum overflow in second pond enters slag gathering hopper; Because the mobility of mud scum is poor, when mud scum be difficult to overflow enter slag gathering hopper time, suitably reduce the height of slag gathering hopper, make a part of water flow into slag gathering hopper, strengthen mud scum mobility; Mud scum in slag gathering hopper is delivered to a dreg collecting slot, the mud scum in dreg collecting slot is expelled to sludge concentration tank or is back to biochemical system with the mud of supplementary loss; Mud scum can either be discharged timely and effectively like this, when a large amount of mud scum causes microorganism to run off, also can supplement biochemical system microbial biomass.
