Device for measuring settling ratio and optimal settling ratio of sludge

Abstract

The invention discloses a device for measuring a settling ratio and an optimal settling ratio of sludge in a mechanical acceleration settling pond and a method for measuring the settling ratio and theoptimal settling ratio of sludge by using the device, wherein the device comprises a shell, a settling assembly, an interface observation assembly and a control assembly, and a cavity is arranged inthe shell; the settling assembly and the interface observation assembly are arranged in the cavity in the shell; the settling assembly comprises two settling pipes which are connected in series, the volume of a first settling pipe is larger than or equal to the volume of a second settling pipe, the first settling pipe communicates with the second settling pipe through a connecting pipe, and the settled and concentrated sludge liquid in the first settling pipe is injected into the second settling pipe. The device of the invention is a portable device with simple structure, small size and compactness, is automatically controlled, is capable of obtaining the settling ratio and the optimal settling ratio of the sludge in the sludge liquid, overcomes artificial subjective factors, has accuratedata measurement, can automatically sample and analyze settling characteristics of the sludge, and provides guidance parameters for tap water treatment operation.

Description

technical field [0001] The invention relates to a sludge analysis device and a sludge analysis method, in particular to an analysis device for sludge settling velocity and an analysis method for an optimum settling ratio during tap water treatment, belonging to the field of water supply treatment. Background technique [0002] The mechanically accelerated clarifier (machine-added tank) is a water purification structure that integrates the flocculation reaction process and the clarification and separation process. It uses the circulating sludge in the tank to contact each other with the impurity particles in the raw water, and flocculates to achieve efficient mud-water separation. Effect. The effluent quality of the machine-added tank is not only related to the appropriate coagulation scheme, but also has a lot to do with the control of the amount of sludge in the tank. The core of the machine-added tank operation is the management of the sludge in the tank. [0003] The "se...

Problems solved by technology

[0012] The purpose of the present invention is to aim at the existing tap water treatment process in the sludge sedimentation ratio measurement and analysis process in the mechanically accelerated clarifier, which has a relatively large human subjectivity, a large subjective influence, and poor accuracy of the measurement data; "To control the amount of sludge and sludge discharge in the machine-added tank, the specific value of the sedimentation ratio cannot be quantified; and the time and frequency of sludge discharge are all based on personal experience, and fine sludge discharge cannot be performed; in addition, it is time-consuming to measure the "sedimentation ratio" , low measurement efficiency, etc., and it is difficult to manually measure the "best sedimentation ratio" and other technical defects. A device for measuring sludge sedimentation ratio and optimal sedimentation ratio and a device for measuring sludge sedimentation ratio and optimal sedimentation ratio using the device are provided. The method, the device of the present invention is a portable device with simple structure, small and compact, and is automatically controlled to obtain the "sedimentation ratio" and "best sedimentation ratio" of the sludge in the sludge liquid, which overcomes the artificial subjective factors, and the data measurement is accurate and can be Automatic sampling and automatic analysis of sludge settling characteristics, providing guiding parameters for tap water treatment operation
