Technical Field
The utility model belongs to the technical field of sewage treatment, and particularly provides a sludge sampling device with a sludge interface observation function, which is used for a high-efficiency sedimentation tank (magnetic coagulation sedimentation tank) in a sewage treatment system.
Background
At present, most municipal sewage treatment plants face the standard upgrading strict with the first-level A standard, a high-efficiency sedimentation tank (magnetic coagulation sedimentation tank) in an advanced treatment system is one of key units in the standard upgrading process, a sludge level is one of key parameters in the operation process of the high-efficiency sedimentation tank (magnetic coagulation sedimentation tank), and the working condition of a sludge scraper, the working condition of a sludge reflux pump and the discharge amount of residual sludge are closely related to the sludge level in the sedimentation tank.
The currently used mud level judgment methods mainly comprise two methods: firstly, install the mud level meter in the sedimentation tank, the mud level meter that is selling is ultrasonic wave mud level meter mostly, and its theory of operation is with the sensor immersion aquatic, utilizes ultrasonic emission and aquatic suspended solid echo analysis, confirms the mud level. Secondly, a sludge sampling pipe is arranged on the side wall of the sedimentation tank, so that manual periodic sampling is needed, sludge concentrations at different heights are measured, and then sludge positions are judged.
In the first method, the ultrasonic mud level meter can only read data through a transmitter display screen, and the distribution condition of the submerged partial mud layer cannot be observed visually. Although the ultrasonic mud level meter has high sensitivity, the error is large, and the accuracy of mud level measurement can be seriously influenced if the turbidity of supernatant in the tank is high or suspended garbage exists. In addition, the ultrasonic mud level meter has high use and operation requirements, needs special training, and has the following problems of instrument calibration and maintenance and the like.
In the second method, the sampling and the measurement are carried out manually and periodically, the workload is high, and the mud level in the sedimentation tank is inconvenient to master in time.
Aiming at the defects, the utility model provides the sludge sampling tube which can accurately judge the sludge level in time.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a sludge sampling device with a sludge interface indication function, which has the advantages of simple and convenient operation, simple later maintenance, low cost and high measurement precision.
The utility model relates to a sludge sampling device with a sludge interface indication function, which comprises a group of sampling tubes, a group of horizontal transparent tubes and a discharge main pipe, wherein the sampling tubes are arranged in the group of horizontal transparent tubes; the rear ends of the group of sampling tubes are respectively connected with the front ends of the group of horizontal transparent tubes in a one-to-one correspondence manner, and the rear ends of the horizontal transparent tubes are communicated with the discharge header pipe; a first valve is arranged between each sampling tube and the connecting and horizontal transparent tube, and a second valve is arranged between each horizontal transparent tube and the discharge header pipe; the sampling ports of the group of sampling tubes are positioned at different heights, the group of horizontal transparent tubes are horizontally arranged from high to low, the upper port of the sludge discharge main pipe is closed, and the lower end of the sludge discharge main pipe is connected to the sludge pump room sump.
In the utility model, the connection sequence of the sampling tube and the horizontal transparent tube is as follows: according to the height of the sampling port, the sampling port is communicated with the horizontal transparent tubes from high to low in sequence in a one-to-one correspondence manner. The height of the sampling ports is dispersed, the horizontal transparent pipes are arranged closely, and the transparent pipe area can be arranged at the height position of the tank wall which is convenient for workers to operate during installation.
Preferably, the valve is a manual butterfly valve. The manual butterfly valve is connected with the pipe fittings at two sides of the manual butterfly valve through flanges.
The utility model also comprises a fixing bracket for fixing the sampling tube, the horizontal transparent tube or the discharge main tube on the wall of the pool.
In the utility model, the horizontal transparent tube is a hard transparent organic glass tube.
The specific number of the sampling tubes in the group of sampling tubes is set according to actual needs, and not less than 3 sampling tubes are recommended. The number of horizontal transparent tubes is the same as the number of sampling tubes.
The utility model observes the liquid state (color, flocculent structure and compaction compactness) in the transparent pipe by controlling the sludge sampling pipe valves with different heights so as to quickly judge the sludge level of the sedimentation tank, solves the problem that the sludge level in the sedimentation tank is difficult to master, can timely adjust the sludge reflux quantity and the sludge discharge quantity, and ensures the good running state of the high-efficiency sedimentation tank (magnetic coagulation sedimentation tank).
Drawings
FIG. 1 is a schematic view of a sludge sampling apparatus according to the present invention. The arrows in the figure indicate the water flow direction.
Detailed Description
An embodiment of the present invention will be described with reference to fig. 1. Before the present embodiments are further described, it is to be understood that the scope of the utility model is not limited to the particular embodiments described below; it is also to be understood that the terminology used in the examples is for the purpose of describing particular embodiments, and is not intended to limit the scope of the present invention; in the description and claims of the present invention.
The sampling port 11 of the sampling tube 1 penetrates through the pool wall to be communicated with the inside of the pool, the vertical height and the interval of the sampling port 11 are set as required, and the recommended interval is 700 mm.
When measuring the mud position, the first valve 4 and the second valve 5 in front of and behind the hard transparent organic glass tube 2 at the highest position are opened first. Observe liquid state in the transparent organic glass pipe of stereoplasm 2, if see mud, the mud level has reached this position promptly, if see the clear water, close this pipe section valve, open first valve 3 and second valve 5 before and after the transparent organic glass pipe of inferior high position stereoplasm 2, analogize from high to low so. And finally, observing the mud level corresponding to the pipeline, namely the actual mud level. The sludge reflux amount and the sludge discharge amount are adjusted through the sludge level, and the good running state of the high-efficiency sedimentation tank (magnetic coagulation sedimentation tank) is ensured.
