Detailed description of the invention
Fig. 1 is 1 structural schematic diagram of the utility model embodiment.
Appended drawing reference includes:
Belt thickener machine 1, screw pump 2, A conditioner 3, B conditioner 4, plate and frame filter press 5, circulating pump 6.
Specific embodiment
The utility model principle is, A conditioner 3 and B are continuously arranged between belt thickener machine 1 and plate and frame filter press 5
Conditioner 4 facilitates realization to carry out the conditioning of zonal cooling biochemistry to sludge after concentration.
The utility model includes: belt thickener machine 1, A conditioner 3, B conditioner 4 and plate and frame filter press 5.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment 1: in certain city's sewage plant case, as shown in Fig. 1, belt thickener machine 1 is sequentially connected A conditioner 3, B
Conditioner 4 and plate and frame filter press 5.
In aforementioned, belt thickener machine 1 is also referred to as integrative belt thickening and dewatering machine, which can round-the-clock continuous and automatic operation.
Belt thickener dewaterer is combined using belt thickener machine and belt filter press, the company applied to various different sludge qualities
Continuous concentration, dehydration, to obtain the mud cake of high solid content.Sludge condensation in enriching section by sludge solid content from 2% or so to
It is suitble to 5% or more of filters pressing, is then dewatered in filter pressing section containing solid 20% or more.Belt thickener machine 1 includes stainless steel frame, again
Power dewatering period, squeeze section, mud rake, driving device, filtering band cleaning unit, strainer tensioning apparatus, strainer tracking and deviation-rectifying system, filter
Liquid catch tray and drain pan, internal wire and pipeline etc., all using abrasion-proof corrosion-proof corrosion material, it is ensured that equipment long-time stable fortune
Row.Belt thickener machine 1 has perfect automatic control and defencive function, once there is sludge quantity deficiency, polymer lacks, and strainer is run
Partially, washing pressure is too low, and compressed air pressure is too low, the equal stopping alarm such as external signal instruction.
In aforementioned, installation screw rod is separately connected between belt thickener machine 1, A conditioner 3, B conditioner 4 and plate and frame filter press 5
Pump 2, meanwhile, 1 feed end of belt thickener machine and 5 discharge end of plate and frame filter press are separately connected installation screw pump 2.
In aforementioned, screw pump 2 namely helicoidal pump, also known as " spiral water lift ", " Archimedean screw pump ".Utilize helical-blade
The rotation of piece, a kind of pump for increase along axial screw shape liquid or solid material.It is made of axis, helical blade, shell.It draws water
When, it will pump in tilting water, and so that the inclination angle of Pump Shaft is less than the inclination angle of helical blade, the lower end of helical blade is contacted with water.When
When prime mover drives the rotation of spiral pump shaft by speed change gear, water enters blade, rises along screw type runner, until going out to flow.
Structure is simple, and manufacture is easy, and flow is larger, and head loss is small, and efficiency is higher, easy to repair and maintenance, but lift is low, revolving speed
It is low, speed change gear need to be set.It is chiefly used in irrigating, water drainage and the occasions such as lifting sewage, sludge.
In aforementioned, A conditioner 3, B conditioner 4 are a kind of adjusting waste discharge water, the inhomogeneities of water quality, reach it
To the uniform and stable processing unit of water, water quality or structures, wherein mountable homogeneous agitating device back work.
In aforementioned, plate and frame filter press 5 is the machinery for being applied to chemical industry dehydration at first.Although plate and frame filter press is generally interval
Operation, building equipment investment is larger, filter capacity is relatively low, but due to its with filtered driving force big, filter cake solid content it is high,
The advantages that filtrate is limpid, solid recovery rate is high, conditioning drug consumption is few, is still widely used in some small sewage treatment plants.It is dirty
Mud is concentrated, after digestion, the moisture content of Shang Youyue 95% to 97%, and volume is still very big.Sludge dewatering can further remove sludge
In interstitial water and capillary water, reduce its volume.By dehydration, moisture percentage in sewage sludge can be reduced to 70% to 80%, body
Product is 1/10 to the 1/4 of original volume, is conducive to subsequent transportation and processing.Mechanical sludge dewatering method has filtering means dehydration, centrifugation de-
Water and press type dehydration etc., filtering means dehydration has vacuum filter and pressure filtration again；Centrifugal dehydration is dehydrated with centrifuge；Pressure
The dehydration of squeezing formula is dehydrated with pressafiner or roller press.The most commonly used is pressure filtrations and Centrifugal dehydration method.Sludge mistake
Filter dehydration is so that sludge water content is forced through filter medium using the pressure difference on filter medium two sides as motive force and formed filter
Liquid, and solid particle is trapped on medium and forms filter cake, to achieve the purpose that sludge dewatering.Plate and frame filter press is to answer at first
Machinery for chemical industry dehydration.Although plate and frame filter press be generally intermittently operated, the larger, filter capacity of building equipment investment also compared with
It is low, but since with filtered driving force, big, filter cake solid content is high, filtrate is limpid, solid recovery rate is high, conditioning chemical consumption for it
The advantages that in amount, is still widely used in some small sewage treatment plants.Plate and frame filter press structurally includes filter plate, filter frame and filter cloth,
In addition to plate compression machine host, also into the corresponding ancillary equipment such as mud system, administration system and compressed air system.
Connection installation circulating pump 6 is drawn in aforementioned, on A conditioner 3, B conditioner 4 and plate and frame filter press 5 respectively to feed back to
Belt thickener machine 1.
In operation, sewage disposal process includes: the utility model embodiment
1) sludge condensation；Persistently thickened sludge is assisted in booting to belt type sludge thickener 1, is then pumped into dirt by a screw pump 2
Mud A conditioner 3, about 5 tons of sludge quantity.It is added the basis 5L microbial inoculum A biochemical reaction 12 hours into A conditioner 3, and appropriate battalion is added
Support substance, glucose 1kg.
2) A conditioner 3 is pumped into sludge B conditioner 4；Add 1L biochemical activity enzyme B and 2L sludge modification microbial inoculum C to B conditioning
Pond simultaneously sufficiently improves, and improves 2 hours.
3) with a screw pump 2 from B conditioner 4 to plate and frame filter press 5 into mud, 1.5 hours.
4) after the completion of plate and frame filter press 5 is fed, start to squeeze, the live squeeze pressure 1.7MPa of plate and frame filter press 5, when squeezing
Between 1.5 hours.
5) 5 dump of plate and frame filter press air-dries, 0.5 hour.
6) moisture content of the cake is measured before air-drying are as follows: 50.85%, moisture content of the cake is measured after air-drying 0.5 hour are as follows:
30.27%.
7) A conditioner 3, B conditioner 4, sewage is precipitated in plate and frame filter press 5 belt thickener machine 1 is fed back to by circulating pump 6,
It is administered again until obtaining middle water extraction up to standard.
