Description

Technical Field

[0001] The present invention relates to the technical field of sludge reduction, and in particular to a sludge treatment and disposal agent screening device. Background Art

[0002] Activated sludge is a general term for microbial communities and the organic and inorganic substances they are attached to. A large amount of residual sludge is produced in the process of biological sewage treatment. Since the residual sludge contains a large amount of organic matter, it is a recyclable resource. However, if it is not treated in time and randomly piled up, pollutants such as nitrogen, phosphorus, heavy metals and harmful chemicals will seep out, polluting the land, rivers, lakes and groundwater, and causing harm to the environment.

[0003] The treatment and disposal of activated sludge is particularly important. Due to its high water content, which can reach over 98%, necessary reduction during the treatment and disposal process is crucial. During sludge reduction, sludge conditioning is necessary. The chemicals used for conditioning are directly related to the sludge's dewatering performance, which is of great significance to the sludge dewatering effect and cost reduction and efficiency improvement. Existing sludge dewatering equipment often equips each chemical device with a stirring motor, which increases the equipment cost. Furthermore, the reaction vessel needs to be cleaned after each experiment, which is not conducive to improving experimental efficiency.

[0004] Therefore, the present invention proposes a drug screening device for sludge treatment and disposal, which is used to screen the drugs in the sludge treatment process. On the one hand, the manufacturing cost of the device is low, and on the other hand, it is convenient for cleaning and replacing the reaction container.

The delivery pump 156 is a peristaltic pump, and a cleaning pipe 157 is also provided at the bottom of each container. A control valve 1571 is provided on each cleaning pipe 157. The cleaning pipes 157 are connected to the sewage tank 3 on the bottom plate 11 after being converged.

The stirring paddle matching hole 1411 matches with the first stirring paddle 1581, and the feed matching hole 1412 matches with the sludge container 151 and the delivery pipes of each chemical container delivery pump 156 respectively.

[0043] Multiple reaction containers 173 can be set up, such as one backup and one use, two backup and two use, and three backup and three use, etc. A valve is set at the bottom of the reaction container 173; a filtration device 4 is placed below the reaction container 173 in the reaction area, and the filtration device 4 is coordinated with the vacuum pump 2 (constant pressure); a beaker 5 container containing cleaning liquid is set below the reaction container 173 in the cleaning area, and the waste liquid in the beaker 5 container is collected in the sewage tank 3; the bottom of each reaction container 173 is connected to the lifting conversion mechanism 17 through a connecting rod 172.

[0044] The lifting conversion mechanism 17 includes a mechanism box 171, which includes an upper half and a lower half. A worm gear 1715 is provided in the upper half (the worm gear 1715 can rotate freely, but the upper and lower spatial positions remain unchanged). The worm gear 1715 cooperates with a worm 1716, and the worm 1716 is connected to a handwheel 1713 outside the upper half; the worm gear 1715 is threadedly connected to a lead screw 1714 at the center of the worm gear 1715.

When the handle 1712 is in the lower end of the strip groove 1711, the reaction vessel 173 is separated from the second support plate 14, and when the handle 1712 is in the upper end of the strip groove 1711, the reaction vessel 173 is located in the through hole on the second support plate 14.

[0045] The principle of the present invention is:

[0046] The device of the present invention can be used for screening sludge treatment agents, and is helpful in screening out treatment agents with good treatment effects, thereby helping to reduce the amount of sludge.

[0047] During use, the sludge from the sewage treatment plant is placed in the sludge container 151, and the agent to be tested is placed in the agent container. Since the agents are often used together during the process, it is often necessary to start multiple agent containers at the same time; after adding the agent to the agent container, the exhaust valve on the air pipe in the matching mechanism 162 is pressed, so that the piston in the annular air chamber contracts, and the spring in the first telescopic support mechanism 1624 bounces up and makes the corresponding first matching gear 1615 match with the second matching gear 1616, so that the transmission mechanism 161 can drive the corresponding second stirring paddle 163 in the agent container to start working; since the sludge container 151 must be set to stir, the sludge container 151 does not need the matching mechanism 162, and one or more agent containers are selected according to actual needs. When the annular air chamber is inflated, the corresponding second stirring paddle 163 in the agent container that is not needed will not start working.

[0048] Since the sludge container 151 and the chemical container are only used for mixing the solution, a very high stirring speed is not required, and is generally 60 to 120 r / min. At this time, the transmission mechanism 161 can operate stably.

[0049] The mixed sludge and reagent are transported to the reaction container 173 through the transport pump 156, and filtered after reaction in the reaction container 173. During the process, the sludge specific resistance can be measured, so as to compare and screen out suitable sludge treatment reagents.

[0050] After one batch of reactions is completed, the reaction vessel 173 needs to be cleaned and another batch of reactions needs to be started. In the present invention, the lifting and conversion mechanism 17 can lower the reaction vessel 173 and then rotate the conversion position. Cleaning can be started on one side while experimental operations are carried out on the other side at the same time, which helps to improve experimental efficiency.

[0051] In the embodiment of the present invention, cleaning can be done manually, but for those skilled in the art, using a clean water tank, a pump, a nozzle, etc. to add water during the cleaning process helps to reduce labor intensity and is more convenient for use in experimental operations.

[0052] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
