Description

High-efficiency sludge concentration, solubilization and dewatering system {SYSTEM FOR CONCENTRATING AND DEHYDRATING SLURRY}

The present invention relates to a high-efficiency sludge concentration and solubilization dewatering system capable of reducing power costs and coagulants and realizing a low moisture content.

The Korean Waste Management Act refers to sludge that has a moisture content of less than 90% or a solids content of 10% or more, but hereinafter, sludge is regarded as the same concept as sludge.

As the number of facilities capable of treating sewage increases nationwide, the amount of sludge generated from sewage treatment is also increasing, and efficient treatment is emerging as one of the major environmental policy tasks.

However, from July 2003, direct reclamation of organic sludge generated from discharge facilities of a certain size or larger was prohibited, and marine discharge adopted by most domestic sewage and wastewater treatment plants is also expected to be banned in stages under the London Convention. In this situation, there is an urgent need for appropriate sludge treatment alternatives, as Sewage Sludge is being suppressed by setting strict standards for marine discharge through the revision of the Marine Environmental Pollution Prevention Act (February 21, 2006).

On the other hand, the unit process used for the treatment/disposal of sludge is classified according to the treatment purpose and function, and the treatment method is divided into a pretreatment step, an intermediate treatment step, and a final treatment step.

The pretreatment step is aimed at increasing and reducing the treatment efficiency of sludge, such as sedimentation, concentration, mechanical dehydration or reduction (digestion) improvement of the sludge, and the intermediate treatment step is to reduce or reduce dewatered sludge for the subsequent final treatment step. As a stabilizing step, processes such as composting, incineration, melting, solidification, and fuelization are used. The final treatment step refers to effectively using the product generated after the intermediate treatment step, such as landfilling or recycling.

Although the importance of resource conversion is emphasized first in the sludge treatment, general composting or composting by earthworm breeding, which are representative methods of recycling conventionally, is difficult to use agriculturally in cities and regions, even in town and town units. In accordance with the Fertilizer Management Act, it is necessary to obtain permission from the president of the Agricultural Science and Technology Institute, and the use of forestry, park greenery, or cover material, not agricultural use, also has limitations in supply and demand.

In the sludge conversion process, sludge fueling, which is another method of recycling sludge, the calorific value of the sludge dewatering cake differs from other wastes. Since it is impossible to control, it is judged that a treatment of increasing the calorific value by controlling the moisture content is necessary. That is, during incineration or composting, it is necessary to increase dehydration efficiency or pretreatment by drying or the like in order to initially remove moisture.

As the existing sludge fueling technology is the core of this technology to efficiently remove 75-85% of water from the sludge dewatering cake, it takes a lot of energy in the drying process of the sludge dewatering cake, and it takes a lot of odor in the drying process. Removal, etc. are required.

On the other hand, no matter which method is used, the sludge having a high moisture content must be processed into a dehydrated cake (hereinafter, referred to as a cake), so that problems such as treatment cost and space can be solved.

Accordingly, Korean Intellectual Property Office Application No. 10-1999-0020404, Korean Intellectual Property Office Application No. 10-2010-0085738, Korean Intellectual Property Office Application No. 10-2014-0002172, Korean Intellectual Property Office Application No. 20-1998-0010628, etc. As shown, various technologies are being developed or partially implemented by various companies, but considering the fact that the effect is still insignificant compared to facilities, a new concept of previously unknown power and coagulant can be reduced and a low moisture content can be realized. Technology development for sludge concentration, solubilization and dewatering system is required.

During the process, the pair of porous drums 130 are configured to rotate in opposite directions, and the sludge discharge unit 124 operates the transfer pump 200 to be described later to the sludge dropped from the pair of porous drums 130. Thus, it can be discharged to the pipe agglomeration device 300 side.

The sludge concentrated in the concentrator 100 is pumped by the transfer pump P and transferred to the ultrasonic module 200 side.

The ultrasonic module 200 of the present embodiment is a device for solubilizing the secondary concentrated sludge, and the sludge transfer pipe 210 through which the sludge is supplied through the inlet 211 on one side and the sonicated sludge is discharged through the outlet 212 on the other side. ), and an ultrasonic generator 220 disposed on the outer surface side of the sludge transfer pipe.

The sludge transfer pipe 210 may serve as a pipe and a reactor. Therefore, there is no need to prepare a separate reactor for solubilizing the sludge.

Accordingly, a plurality of ultrasonic generators 220 disposed on the outer surface of the sludge transfer pipe 210 irradiate ultrasonic waves to the sludge in a non-contact manner that does not contact the sludge flowing in the sludge transfer pipe 210, and the sludge transfer pipe ( 210) causes cavitation in the sludge.

In the cavitation process, high temperature (5000K), high pressure (500bar), jet flow (100m/sec) are generated, and OH radicals are generated and the cell walls of microorganisms are destroyed by chemical oxidation, resulting in solubilization of sludge.

The pipe agglomeration device 300 is a device that increases the strength of a flocculating floc by introducing sludge transferred from the ultrasonic module 200 and a small amount of a flocculant.

As such, the pipe agglomeration device 300 is applied to the system, thereby increasing the strength of the flocculating floc. Therefore, there is no need for a mixing tank as in the past, and in particular, there is an advantage that the amount of coagulant such as polymer can be reduced by 10% to 30%.

In particular, the auto grease dispenser 312 is disposed at a location where the bearing of the cohesive shaft module 311 is located, so that the grease can be automatically supplied to the bearing.

The dehydrator 400 is a dehydration device for dewatering the sludge supplied from the pipe agglomeration device 300 and carrying it out to a cake.

Filter press dehydrator and screw press dehydrator can be applied as a dehydrator. In this system, the power is low, so it is possible to reduce the amount of carbon dioxide (CO2) generated, as well as low-speed operation. A screw press dehydrator 400 that can greatly improve the can be applied.

In particular, the dehydrator 400 according to the present embodiment has an effect of reducing carbon dioxide (CO2) of 0.348 kg per 1 kw of power, and the operation rpm is low at 0.2 to 0.8.

Since the above-described concentrator 100 and pipe agglomeration device 300 are passed, the throughput in the dehydrator 400 can be increased by 0.5 to 2 times, the solids recovery rate can be increased by 95% or more, and the moisture content of the cake can be increased by 2 or more than that of the existing dehydrator. Since it can be lowered by more than 5%, the economic feasibility of operating the system can be improved.

As such, the processes of the present invention may be implemented by software executed on a computer system, or by hardware such as an integrated circuit, or by a combination of software and hardware.
