Abstract
The invention relates to a sludge thickening and dehydration system which comprises a sludge storage pool connected with a dosing tank through a sludge pump, wherein the dosing tank is sequentially connected with a microstrainer, a screw pump and plate-and-frame filter presses, and the dosing tank is further connected with a dosage tank through a metering pump. By means of the sludge thickening and dehydration system, the sludge is firstly filtered by a microstrainer before entering the plate-and-frame filter presses, the filtering period can be shortened by a half by means of dehydration of the plate-and-frame filter presses, and the number of the plate-and-frame filter presses can be saved. The sludge thickening and dehydration system can save investment and can further reduce operation cost.
Description
Technical field
The invention belongs to sewage treatment area, be specifically related to a kind of sludge concentration and dewatering system.
Background technology
Mud is the product of sewage treatment area, is mainly derived from the process procedures such as primary sedimentation pond, secondary sedimentation basins.Per ten thousand m of urban wastewater treatment firm
3
Sewage after treatment sludge creation amount (by water ratio 80%) generally is about 5 ~ 10 t, and concrete output depends on the factors such as draining system, influent quality, sewage and sludge treatment technique.And the industrial sewage sludge yield is according to dissimilar sewage, and its output also has very large difference.
The sludge treating system of sewage work generally all configures sludge thickener and sludge dehydration device.Existing sludge thickener, general square or circular, the degree of depth more than 6 meters, mud flows in this pond, because the proportion of mud is slightly heavier than water, by slowly sedimentation, the mud a little volume-diminished of consolidation that become, thereby water ejects water ratio decline between mud, forms supernatant liquor and drains by the upper strata water shoot, and is this by the concentrated method of mud action of gravity, more than the very time-consuming 12h, and thickening efficiency is low, can only drop between 98% ~ 99%, and namely sludge volume reduces more than 1 half.
If rare mud Direct Dehydration (such as press filtration) of this high-moisture will increase the operating load of device for dehydrating sladge waste, reduce design and operation efficient, increase facility investment and running cost.
Through the sludge quantity of dehydration often its volume be tens times of dehydrated sludge, for example when moisture percentage in sewage sludge is reduced to 90% from 99.5%, the mud weight after concentrating only has 1/20 of primary sludge weight.In engineering design, in order to guarantee the normal operation of sludge treatment, during lectotype selection, mud handling capacity is all greater than actual sludge creation amount.
Summary of the invention
Technical problem to be solved by this invention has provided a kind of highly effective sludge thickening system.Use this mud concentration systems, can effectively reduce sludge moisture content, and reduced the quantity of dehydration equipment, reduced the working cost of sludge treatment.
To achieve these goals, adopted following technical scheme:
A kind of sludge concentration and dewatering system comprises storage basin, and storage basin is connected with grug feeding jar by sludge pump, and grug feeding jar links to each other with plate-and-frame filter press with Microfilter, spiral pump successively, and described grug feeding jar also links to each other with dispensing canister by volume pump.
Described Microfilter comprises rotary drum and the microscreen that is fixed on the rotary drum.
The micropore size of described microscreen is at 100 ~ 200 orders.
Microfilter is that microscreen is fixed on the rotary drum, by holding back solid particulate in the water body, realizes the device of solid-liquid separation.When filtering, can microscreen be cleaned timely by the rotation of rotary drum and the reactive force of back-flushing, make equipment remain good working order.
Sludge concentration and dewatering of the present invention system is when work, rare mud in the storage basin is delivered to grug feeding jar by sludge pump, in grug feeding jar, flow automatically to Microfilter after flocculation agent and the rare mud hybrid reaction, because mud and flocculation agent reaction link together and have increased the volume of mud flco, compressed interstitial water between flco, when in Microfilter, rotating, large mud flco is screen cloth only thoroughly, and moisture content sees through screen cloth easily, along with the rotary type screen cloth ceaselessly rotates, the mud that separates with the baffle plate of spiral with motion up forward, through taking up several times, after falling, moisture percentage in sewage sludge further reduces, and finished to travel forward and entered the mud collecting tank, the clear water that produces is disposed to equalizing tank, and the mud after concentrated will be delivered to plate-and-frame filter press by spiral pump and dewater, and the mud after the dehydration enters next step sludge treatment mechanism or outward transport and disposes.
Use this sludge concentration and dewatering of the present invention system, because before entering plate-and-frame filter press, mud filters by Microfilter first, can shorten half through press filtration cycle of plate-and-frame filter press dehydration, can also save the quantity of plate-and-frame filter press.So not only can reduce investment outlay, but also can reduce running cost.Microstrainer structure is simple, convenient operation, maintenance and cleaning.
Description of drawings
The structural representation of Fig. 1 sludge concentration and dewatering system.
Fig. 2, the structural representation of Microfilter.
Embodiment
As shown in Figure 1, a kind of sludge concentration and dewatering system comprises storage basin 1, and storage basin 1 is connected with grug feeding jar 3 by sludge pump 2, grug feeding jar 3 links to each other with plate-and-frame filter press 8 with Microfilter 6, spiral pump 7 successively, and described grug feeding jar 3 also links to each other with dispensing canister 4 by volume pump 5.
As shown in Figure 2, described Microfilter comprises rotary drum and the microscreen that is fixed on the rotary drum.The micropore size of described microscreen is at 100 ~ 200 orders.
When the present invention works, the mud discharging that sewage work mesophytization pond or settling tank produce is to storage basin 1, be promoted to grug feeding jar 3 by sludge pump 2, rare mud (water ratio is more than 99.5%) carries the flocculation agent of coming to mix with deployed from dispensing canister 4 by volume pump 5 in grug feeding jar 3, then gravity flow enters Microfilter 6, under the condition of certain rotating speed, after the microscreen filtration, solid matter in the mud and water initial gross separation, isolated thickened sludge (about water ratio 90%) flow to the mud receiving tank certainly, and the clear water 8 of collecting is from flowing to equalizing tank 9.
Be delivered to plate-and-frame filter press 8 through the mud (about water ratio 90%) after concentrated by spiral pump 7 and dewater, the mud after the dehydration (about water ratio 75%) will carry out next step disposal, certainly flow to equalizing tank 9 through plate-and-frame filter press 8 isolated clear water.
