Description
Technical field
The present invention relates to sludge dewatering treatment technical field, especially a kind of to flat flow Sludge from primary sedimentation tank concentration method.
Background technology
Along with the quickening of urbanization process and the raising of people's living standard, the quantity discharged of urban industry waste water and sanitary sewage is increasing, and the growth of sewage load and the requirement of advanced treatment of wastewater will produce more mud.The mud produced defines a comparatively serious problem for sewage work, and its reason is: high for the water ratio in the mud produced in sewage treatment process, volume large, and moisture is difficult to remove; And traditional process for the mud after sewage disposal is the technique means such as compost, burning, landfill, but these technique means are all difficult to meet the requirement of GB/T23485-2009 to moisture percentage in sewage sludge.
Meanwhile, the moisture contained in mud can be divided into surface adsorption water, interstitial water, capillary Bound moisture, internal junction Heshui four kinds; And mud is cotton-shaped colloid set to be formed, when an external force is applied, gluey fine particle will block and form filter bridge, increases the ratio resistance of filtration; Cause machinery deviate from (as centrifugal deviate from) moisture difficulty in mud is comparatively large, extrusion rate is lower, and then causes the moisture content in mud higher; And, the material that a large amount of organic substances, bio-toxicity pollutent etc. have a strong impact on environmental quality is still also there is in the mud produced in sewage treatment process, and then cause in sewage treatment process, then mud is carried out to the means process such as compost, burning or landfill and will bring serious pollution to environment; For this reason, we are badly in need of will finding a kind of organic substance wherein of can degrading, bio-toxicity pollutent and gluey fine particle can being avoided to form the sludge reduction treatment method of filter bridge.
Summary of the invention
In order to solve the above-mentioned technical problem existed in prior art, the invention provides a kind of to flat flow Sludge from primary sedimentation tank concentration method, sewage can be precipitated in horizontal sedimentation tank and the Bound moisture existed in mud can be decomposed out, again in conjunction with the extrusion process of grab bucket, make part Bound moisture obtain extruding in advance to flow out, and then be reduced in the pressure to sludge treatment in concentration basin, reduce the cost to sludge condensation process, reduce the load of pressure filter, there is significant economic benefit.
Be achieved particular by following technical scheme:
A kind of to flat flow Sludge from primary sedimentation tank concentration method, draw together following steps:
(1) sewage is entered in flat flow preliminary sedimentation tank, and the iron powder accounting for sewage weight 1-5% is added according to the amount of sewage, and make its employing stirring speed in flat flow preliminary sedimentation tank be after 200-500r/min stir process 2-3h, add the carbon dust accounting for sewage weight 2-5% more wherein, and employing stirring speed is 1000-2000r/min stir process 10-20min, under being placed on normal temperature environment again, leave standstill process 1-10h, stand-by;
(2) transfer gantry is adopted, and hang oneself one at the cable wire of transfer gantry and grab bucket, and fall into flat flow preliminary sedimentation tank by grab bucket, by grab bucket the mud in flat flow preliminary sedimentation tank picked up and move in concentration basin, and in the process of grabbing mud, grab bucket adopts squeeze to be 5.7-6.5kg/m
2extruding mud, extrusion time is 5-10min, to be extruded complete after, be positioned in concentration basin, adjustment concentration basin temperature is 30-50 DEG C, after placing 50-70min, then is placed in pressure filter and adopts pressure to be 6.1-6.5kg/m
2press filtration process, can complete the concentration of mud.
Described iron powder is the powder of 500-900nm.
Described carbon dust is the powder of 300-700nm.
Compared with prior art, technique effect of the present invention is embodied in:
By sewage being sent in the first settling tank of flat flow, and iron powder and carbon dust is added in flat flow just settling tank, and then make iron powder and carbon dust form light electrolysis in settling tank, and pass through sewage and iron powder, carbon dust carries out stir process under mix and blend, iron powder and carbon dust are mixed thoroughly in settling tank, and then the microbattery making iron powder and carbon dust be formed can spread all over whole settling tank, make the organism in mud, microorganism wall can be degraded or be broken under the effect of light electrolysis, again in conjunction with the extrusion process of transfer gantry grab bucket, and then the coloring matter of sewage is removed, also make the water in the microorganism wall in mud for dissociating out, reduce the Bound moisture content in mud, reduce the difficulty to sludge condensation process, improve the dehydration rate of mud, reduce press filtration load and the difficulty of pressure filter, reduce sludge treatment cost.
Technical process of the present invention is short, and energy consumption is low, and cost is low, can deviate from the moisture in mud in a big way, reduce the difficulty processed further mud, improve the enrichment factor to mud, reduces concentrated energy consumption.
