Description

Vertical collector for sludge or sewage}

The present invention relates to a sludge vertical water collecting system, and more specifically, by installing a check valve when sampling sedimented sludge or sewage at the bottom layer in various lakes or sewage treatment plant sedimentation basins, it is possible to directly remove contaminants having the same height as the height of the bottom layer. By collecting and measuring, the present invention relates to a sludge vertical water collecting system, which facilitates analysis of various kinds of contaminants according to heights and various kinds thereof.

In the water treatment process, it is classified into two processes. First, it is divided into sedimentation basin which removes sand or contaminants and several sedimentation basins which are solid-liquid separated by collision and condensation between pollutant particles. In wastewater treatment, sedimentation mainly through flocculating chemicals is induced, and sewage treatment induces gravity sedimentation due to specific gravity.

Second, in the process of using the microorganisms activated by biological treatment process, suspended particles and soluble organics in the sewage from the initial settler are subjected to adsorption oxidation process by microorganisms in the aeration tank where a certain amount of air is supplied, and then solid-liquid separation from the final settler. The separated symbol water is finally discharged to the river or the sea.

Generally, sewage or wastewater treatment or tap water is purified, and sedimentation is inevitably generated in the sedimentation basin, and this sludge is solid-liquid separated by forced sedimentation by natural sedimentation or a separate flocculant. This precipitated material is collected using a sludge removal device and then pumped into the sludge treatment process by a pump.

The sludge removal is measured after the depth of the sludge layer is removed so that sludge can be removed before a certain thickness of sludge is accumulated for smooth operation of sewage, wastewater treatment plant and water treatment plant and good wastewater treatment.

Therefore, if the height of the sludge accumulated in the sedimentation basin is not accurately measured, the sludge cannot be processed in a timely manner. If the height of the sludge accumulated in the sedimentation basin exceeds a certain height, the sludge does not settle and is discharged with clean water, causing environmental pollution. Of course, this will delay the wastewater treatment time.

However, the thickness of sludge deposited in the sedimentation chamber is very difficult to visually observe from the outside, and when the sludge is excessively deposited, excessive load is generated on the scraper of the sludge collector, and sludge decay, bulking, odor and overall treatment process Since the sludge depth was measured by inserting a rod into the sedimentation chamber because of the bad effect of the sludge, the sludge on the rod was washed out in the sewage when the rod was removed from the sedimentation chamber. In this case, it is misjudged by the depth of the sludge buried at this time, and the proper operation of the sludge collector or the sludge drawing pump is insufficient, resulting in imbalance of the mass balance, resulting in poor final discharge water quality.

As such, various measuring apparatuses are used to measure the depth of sludge accumulated in sewage treatment plants, sewage treatment plants, sedimentation basins, and water purification plants.

For example, an underwater measuring device using ultrasonic reflection sound and an ultrasonic measuring device to measure sludge depth by using an ultrasonic image, and LED infrared emitters and light receiving sensors are attached to a bar facing each other to use light attenuation below the sludge interface. Infrared measuring devices are used in water treatment plants.

However, among the conventional sludge depth measuring devices, the ultrasonic measuring device and the infrared measuring device are expensive equipment costing tens of millions of won, which requires a lot of installation cost, and the measuring sensor is contaminated with various pollutants due to the turbid water property of the water treatment plant. The measurement error is severe.

In addition, in order to prevent such measurement errors from occurring, the cost of maintenance increases due to the inconvenience of frequently cleaning the measuring device including the sensor and the frequent failure due to interference such as electromagnetic induction in the electronic circuit.

The present invention was devised to solve the above problems, and by installing a check valve, it is possible to collect sewage sludge or sewage accumulated in the bottom layer in various appeals or sewage treatment plant sedimentation basins without disturbing, and thus accurate depth or depth of sludge It is possible to measure the pollution degree and temperature of sewage according to this, and it is possible to measure even the deep water appeal by screwing in a multi-stage, and to provide a sludge vertical water collector that can be easily separated and cleaned. .

In order to achieve the above object, the sludge vertical sludge meter according to the present invention is a sludge vertical sludge meter for measuring the pollution level of the lake or the sediment or sludge of the ecosystem and sewage. A transparent body which can be seen through the inside so as to be seen with the naked eye, and a tubular main body inscribed with a scale to measure the degree of contamination according to the depth or depth of the sediment or sludge; It is installed in the lower part of the main body, characterized in that consisting of a check valve for preventing the inflow of sediment, sludge or sewage, such that they escape.

In addition, it is preferable that the main body of the present invention is provided with a screw fastening portion extending in multiple stages of the main body and the other main body so that even in a deep appeal.

Hereinafter, look at the configuration and operation of the sludge vertical intake system according to the present invention in more detail through a preferred embodiment of the present invention.

1 is a perspective view of a sludge vertical intake system according to an embodiment of the present invention.

As shown, the sludge vertical intake system according to an embodiment of the present invention consists of a main body (1) and opening and closing means (2).

The main body 1 has an upper and a lower part open so that sewage or sludge can be accommodated into the main body without the resistance of air when the main body is inserted into the main body, and the inside is projected to visually check the degree of contamination of the sewage. A transparent round tube, which can be seen, is made of synthetic resin. Moreover, the scale 2 which shows the depth of water from the bottom is displayed on the outer peripheral surface of the said main body. Therefore, the depth of the sludge according to the depth can be measured, and turbidity, saturation, lightness, BOD, COD, etc. of the appeal depending on the depth can be measured. In addition, the main body is preferably provided with a plurality of thermometers (3) on one side inside so that the temperature of the appeal or sewage according to the depth can be measured. Therefore, after taking the sludge vertical sump out of the water, the temperature of the sampled sewage is changed by the temperature in the air, thereby making it possible to accurately measure the underwater temperature, which is difficult to measure.

The opening and closing means (4) is coupled to the lower part of the main body, and when it is introduced into the water to allow the sediment, sludge or sewage, etc. to be introduced into the main body, and serves to prevent the sludge, etc. to escape when taken out after the collection. do.

Figure 2a is a state diagram when the water collection using the ball-type check valve according to a preferred embodiment of the present invention, Figure 2b is a state diagram after the water collection using the ball-type check valve according to a preferred embodiment of the present invention. 3 is an operation using a plate-type check valve according to a preferred embodiment of the present invention.

As shown in the drawing, the main body is put in the water to be introduced to the bottom, or to any depth, the input of the main body at the time of harvesting, the ball 5 is raised by the water pressure, that is, the lower body The check valve 6 coupled to the opening is opened so that sewage, water, sludge, etc. are received in the main body (see FIG. 2A). In addition, after the water is collected, the ball is lowered by the weight of sewage, water, sludge and the like stored in the main body, and the check valve is closed, and is taken out while accommodating the sewage, water, and sludge (see FIG. 2B). In FIG. 3, when the main body is put in during harvesting, the plate 7 is raised by the water pressure so that sewage, water, sludge, etc. are accommodated in the main body (see solid line). As a result, the check valve is blocked by the weight of the plate and is taken out with the waste water contained in the main body.

At this time, an elastic body such as a spring may be used as the closing means due to the weight of the ball or the plate. When injecting the main body, the water pressure is increased to exceed the spring force of the spring and the valve is opened. When the main body is taken out after the harvest, the water pressure is lowered and the valve is closed by the spring force.

Figure 4 is a state diagram showing an extended sludge vertical water collector according to a preferred embodiment of the present invention.

As shown, the main body is preferably formed with a screw fastening portion 8 to connect the main body and the main body in a multi-stage so that even in a deep appeal. In order to accurately analyze the water quality, the main body should be cleaned frequently, and by installing the screw fastening part, there is an advantage of easily cleaning the inside of the main body by separating the connected main body.

According to the configuration as described above, the user analyzes the water quality by the following method using the sludge vertical water meter of the present invention.
