Technical Field

The utility model relates to the technical field of slow flow devices, in particular to a slow flow tank suitable for monitoring the turbidity of clear liquid of a landfill leachate ultrafiltration system.

Background

The garbage leachate treatment system adopts an ultrafiltration system to replace a secondary sedimentation tank in the traditional process for sludge-water separation, so that the concentration of activated sludge in a front-end biochemical system is improved, and meanwhile, the produced water clear liquid is ensured to contain no suspended substances. The produced water after ultrafiltration separation enters an ultrafiltration water production tank and then passes through a nanofiltration membrane and reverse osmosis membrane system advanced treatment system, so that the COD of the produced water meets the requirement of the effluent quality standard.

In order to ensure that ultrafiltration clear liquid meets the requirements of a nanofiltration membrane and reverse osmosis membrane treatment system on the turbidity of inlet water, a turbidity sensor is usually arranged on an ultrafiltration water-producing up-flow pipeline and is used for monitoring the mud-water separation condition of the ultrafiltration system. However, because the ultrafiltration produced water has higher flow rate and fine bubbles exist, the optical detection result of the turbidity sensor is affected, the monitoring data is distorted, the turbidity meter cannot be used for judging whether the ultrafiltration system leaks mud, and when activated sludge leaks into ultrafiltration clear liquid, serious pollution and blockage of a subsequent advanced treatment system can be caused, so that the normal production operation is affected.

Description of the embodiments

The following description is presented to enable one of ordinary skill in the art to make and use the utility model. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art.

The slow flow tank suitable for monitoring the turbidity of the clear liquid of the landfill leachate ultrafiltration system as shown in figures 1-3 comprises a slow flow tank body 1, wherein an overflow port 3 is formed in the top end of the slow flow tank body 1. When the ultra-filtration clear liquid flows through the turbidity sensor through the S-shaped flow channel, the actual turbidity of the ultra-filtration clear liquid can be measured, and the detected clear liquid is discharged out of the slow flow groove through the ultra-filtration clear liquid overflow port, so that the continuous monitoring of the turbidity of the ultra-filtration clear liquid is realized.

The top of the slow flow box body 1 is provided with an opening, the bottom of the slow flow box body 1 is provided with a water inlet and a water outlet 4, and the water inlet and the water outlet 4 are distributed on two sides of a plurality of guide plates 5. After the ultrafiltration membrane mud leakage is properly treated, the liquid mixed with the activated sludge in the slow flow groove can be immediately discharged from the water outlet 4, and the normal turbidity monitoring is recovered.

The inside two symmetries of slow flow box 1 have all welded a plurality of guide plates 5, and the bottom of a plurality of guide plates 5 all contacts with the inside bottom surface of slow flow box 1, dislocation set between two adjacent guide plates 5, and guide plate 5 is equipped with three at least, and three guide plate 5 equidistance are arranged. The plurality of guide plates 5 which are arranged in a staggered way are beneficial to separating tiny bubbles in the clear liquid from the water body, and meanwhile, impurities in the liquid can still keep in a suspended state to flow through the turbidity sensor, so that the accuracy of monitoring the turbidity of the ultra-filtered clear liquid is ensured.

The top of the slow flow box body 1 is provided with a cover plate 6 corresponding to the opening position through a screw, and the top of the cover plate 6 is provided with a turbidimeter mounting cylinder 7 in a penetrating way. The turbidity meter mounting cylinder 7 can be used for mounting the turbidity meter, so that the turbidity meter can conveniently detect the gap of the water solution in the slow flow box body 1.
