Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sludge treatment equipment, and particularly relates to a continuous sludge thin-layer filter pressing and dewatering integrated equipment. BACKGROUND

[0002] According to the Sludge Quality for Disposal by Landfill (GB / T 23485-2009), the sludge discharge standard of a sewage treatment plant is 60% of water content. Old sludge dewatering equipment such as a belt filter press, a centrifugal dewatering machine and a stacked screw dewatering machine can only dewater sludge to 80% of water content, and cannot meet the requirement of 60% of water content.

[0003] However, the equipment capable of dewatering sludge to 60% of water content has respective disadvantages. For example, low-temperature condensation dewatering equipment, disc dewatering equipment and paddle dewatering equipment rely on heat to reduce the water content of sludge to below 60%, and such equipment has high energy consumption and needs a large amount of heat source to provide heat energy to evaporate water in sludge. A plate-and-frame filter press relies on mechanical dewatering, has a large floor area, many auxiliary equipment and often needs a two-story structure of 15 meters high to ensure installation and operation of the equipment. For old sludge treatment facilities, upgrading and reconstruction, sewage treatment plants with insufficient space planning and limited foundation bearing and river channel sludge treatment plants with a wide working surface, there are problems of unqualified water content of sludge, insufficient land area, high investment and operation cost and the like.

[0102] In the embodiment of the present application, when used, first, the sludge with a moisture content of 99.2% and 98% in the secondary sedimentation tank and sludge thickening tank of the sewage treatment plant is input into the thickening and dewatering system 4 by the transfer screw pump, which is to greatly improve the sludge treatment efficiency, and at the same time, the intelligent control system 1 reads the sludge input amount according to the flow reading of the transfer flow meter, calculates the flocculant dosing pump frequency internally, and feeds the frequency to the automatic dosing system 3, which adds the flocculant into the thickening and dewatering system 4 according to the frequency feedback from the intelligent control system 1, and the sludge and the flocculant are preliminarily dewatered in the thickening and dewatering system 4 to obtain pretreated sludge with a moisture content of 80%, which is then input into the conditioning system 5; for the reconstruction of the old sludge dewatering system, the 80% sludge in the old dewatering room can be directly transported into the conditioning system 5 of the present equipment, thereby saving the investment of the thickening and dewatering system and part of the intelligent dosing system; after the pretreated sludge is input into the conditioning system 5, it is quantitatively transported to the double-shaft mixer by the unloader, and at the same time, the intelligent control system 1 and the automatic dosing system 3 jointly control the addition of the coagulant to the double-shaft mixer, the coagulant and the pretreated sludge are uniformly mixed in the mixer, the dewatering performance of the pretreated sludge is changed, and the specific resistance of the sludge is reduced, which is beneficial to the subsequent sludge filter pressing, the double-shaft mixer has both mixing and stirring functions and conveying function, and the conditioning and modification of the sludge are completed in the conveying process, the well-conditioned and modified sludge is transported into the thin-layer smearing system 6 and waits for the next process; the conditioned sludge is spread and filter pressed to remove part of the water in the thin-layer smearing system 6, the conditioned sludge is uniformly smeared on the filter belt by a scraper to form a thin layer of sludge with a thickness of 2-3 mm, the thin layer of sludge is embedded in the filter belt, and preparation is made for filter pressing and dewatering, and then the thin layer of sludge enters the continuous filter pressing system 7, is filter pressed by 12 filter pressing rollers and 2 booster rollers of the continuous filter pressing system 7, the 2 booster rollers are powered by the pneumatic booster system 8, and the moisture content of the thin layer of sludge can be reduced to 60%, at this time, the thin layer of sludge with the dewatered water is peeled off from the filter belt by a separator at the tail end and is concentrated into the sludge outlet by a conveying screw; the equipment is an intelligent, equipment integrated and integrated equipment which is characterized by construction saving, convenient construction and installation, stable and energy-saving operation, convenient maintenance and management, simple equipment operation, optimized process performance, etc., and is more energy-saving in the whole life cycle of the equipment.

[0103] The present application is a continuous sludge smearing thin-layer filter pressing and dewatering integrated equipment, the treatment scale can be designed according to the actual situation, and the sludge after treatment can meet the requirement of moisture content of 60% in the Sludge Quality for Disposal by Landfilling of Municipal Wastewater Treatment Plant (GB / T 23485-2), and the sludge can be resourceized according to the relevant standards and specifications.

[0104] The conditioning system 5 is realized by cooperating with the automatic dosing system 3 and the intelligent control system 1, realizing automatic conditioning of sludge, realizing control of the amount of dosing while fully conditioning the sludge, accurately dosing according to the dosing proportion designed by the system program, avoiding waste of the reagent, reducing the consumption of the reagent, 80% of the sludge with water content output by the thickener enters the conditioning system 5, is transported to the double-shaft mixer through the unloader in the conditioning system 5, meanwhile, according to the running frequency of the unloader, the intelligent control system 1 will automatically measure the amount of sludge entering the mixer, calculate the running frequency of the dosing pump according to the dosing proportion designed in the system, and the automatic dosing system will add the modified reagent to the mixer according to the frequency feedback by the intelligent control system 1, the sludge and the modified reagent are mixed and reacted in the double-shaft mixer to achieve the modification effect, and the specific resistance of the sludge is reduced, providing a prerequisite for pressure filtration dewatering.

[0105] The sludge dewatering efficiency is inversely related to the thickness of the sludge, that is, the thicker the sludge, the longer the path of the water in the sludge, the more difficult the dewatering, and the higher the required pressure. In the thin-layer troweling system 6, the scraper can uniformly trowel the sludge on the filter cloth to form a 2-3mm thick thin-layer sludge and form a concave-convex tooth-shaped surface with the filter cloth surface. On the one hand, this reduces the thickness of the sludge cake, reduces the path length of the water in the sludge, reduces the dewatering difficulty, and improves the dewatering effect. On the other hand, the sludge is combined with the filter cloth in a concave-convex tooth-shaped surface, increasing the specific surface area of the sludge and the filtration area. The embedding of the sludge and the filter cloth also allows the filter cloth to receive a vertical pressure that can be divided into a horizontal action from the inclined surface to press the sludge, increasing the dewatering effect.

[0106] The continuous pressure filtration system 7 is provided with 12 pressure rollers, the radii of the pressure rollers gradually decrease and present an S-shaped distribution. The initial pressure filtration roller has a large radius and a slow angular velocity, and a small acting pressure, which is used to preliminarily squeeze out the water in the thin-layer sludge and improve the forming effect of the thin-layer sludge. When the thin-layer sludge is not formed and has poor plasticity, the system provides a large pressure to prevent the thin-layer sludge from overflowing. As more pressure filtration rollers are passed, more water is squeezed out of the thin-layer sludge, and the forming effect of the thin-layer sludge is better. The 12 pressure rollers gradually reduce the diameter, increase the rotating speed, and increase the pressure filtration pressure to gradually squeeze out the water in the sludge, and finally achieve the predetermined dewatering effect.

[0107] The pneumatic pressure boosting system 8 is two pneumatic pressure boosting rollers added at the end of the continuous pressure filtration system 7. Unlike the previous 12 fixed pressure rollers, the two pressure boosting rollers are movable pressure rollers, and the air compressor matched with the system provides power for the two pressure boosting rollers. When the sludge is pressed to this step, the two pressure boosting rollers will push against the last two fixed pressure rollers to boost the pressure of the last two pressure rollers and increase the dewatering effect. The sludge is dewatered to the predetermined effect through thickening, conditioning, troweling, pressure filtration, and pressure boosting, and finally meets the discharge standard.

[0181] The above embodiments of the present invention provide a continuous sludge thin-layer filter press dewatering integrated equipment. This equipment comprises an intelligent control system 1, an aerodynamic system 2, an automatic dosing system 3, a thickening and dewatering system 4, a conditioning system 5, a thin-layer coating system 6, a continuous filter press system 7, and a pneumatic pressurization system 8. In operation, sludge with a moisture content of 99.2% and 98% in the secondary sedimentation tank and sludge thickening tank of a wastewater treatment plant is first fed into the thickening and dewatering system 4 by a transfer screw pump. This step is to significantly improve sludge treatment efficiency. Simultaneously, the intelligent control system 1 reads the sludge inflow rate based on the transfer flow meter and calculates the internal flow rate. The calculated flocculant dosing pump frequency is fed to the automatic dosing system 3. Based on the frequency feedback from the intelligent control system 1, the automatic dosing system 3 adds flocculant to the thickening and dewatering system 4. The sludge and flocculant undergo preliminary dewatering in the thickening and dewatering system 4 to obtain pre-treated sludge with a moisture content of 80%, which then enters the conditioning system 5. For retrofitting older sludge dewatering systems, 80% of the sludge from the old dewatering machine room can be directly transported into the conditioning system 5 of this equipment, eliminating the need for investment in the thickening and dewatering system and part of the intelligent dosing system. After entering the conditioning system 5, the pre-treated sludge is quantitatively conveyed to the twin-shaft mixer by the unloader. Simultaneously, the intelligent control system 1 and the automatic dosing system... System 3, under joint control, adds coagulant to the biaxial mixer. The coagulant mixes evenly with the pretreated sludge in the mixer, altering the dewatering performance of the pretreated sludge, reducing its specific resistance, and facilitating subsequent sludge pressure filtration. The biaxial mixer has both mixing and conveying functions, completing sludge conditioning and modification during the conveying process. The conditioned sludge is then conveyed into the thin-layer coating system 6, awaiting the next step. In the thin-layer coating system 6, the conditioned sludge is spread and pressure-filtered to remove some moisture. Then, a scraper evenly spreads the conditioned sludge onto the filter belt, forming a 2-3 mm thin layer of sludge. This thin layer of sludge is embedded in the filter belt, preparing for pressure filtration and dewatering. The thin layer of sludge is then fed into the continuous filter press system 7. After passing through 12 filter rollers and 2 booster rollers (powered by a pneumatic booster system 8), the moisture content of the thin layer of sludge can be reduced to 60%. At this point, the dewatered sludge is separated from the filter belt by a separator at the tail end and fed into a conveyor screw at the lower end for discharge. This equipment is an intelligent, modular, and integrated system that is economical to construct, easy to install, stable and cost-effective in operation, convenient to maintain and manage, simple to operate, and optimized in terms of process performance. Furthermore, it is more economical throughout its entire lifespan.
