The present invention relates to a sewage treatment system for treating wastewater, sewage, and the like, comprising: a housing; an SBR reaction unit provided in the housing for purifying wastewater flowing in and an LOC water quality measurement unit for measuring the quality of wastewater in the SBR reaction unit; SBR (Sequencing Batch Reactor) method which can save the site and establishment of the sewage treatment system which is provided through civil engineering and architecture services such as car and washing machine are provided by utilizing the LOC water quality measurement unit To a commercial sewage treatment system.

As a conventional technique using such SBR, there is a registered trademark 10-0670231 " SBR SBR wastewater treatment system &

The above-mentioned prior art has been applied to an SBR reaction tank, a storage tank, a nitrogen storage tank, and the like so as to effectively remove organic substances, nitrogen and phosphorus contained in wastewater having a low C / N ratio (organic / nitrogen ratio) Nitrification tank. Each of the reactors is operated in a batch manner. In particular, the present invention proposes a rejuvenated SBR wastewater treatment system that can significantly improve the nitrogen treatment efficiency as compared with the existing SBR (Sequencing Batch Reactor) process.

In the prior art, the first anaerobic contact tank, the second nitrification tank, and the third intermittent aeration tank are connected to each other in succession (SBR), and after returning sludge and wastewater to the first anaerobic contact tank and reacting for a predetermined period of time, separating the sedimentation sludge and the wastewater from which the microorganisms have been adsorbed, and discharging wastewater into the second nitrification reactor, And the precipitated sludge flows out to the third intermittent aeration tank to be used as an organic carbon source for the denitrification and dephosphorization reaction. The efficiency of denitrification and denitrification can be increased by maximally utilizing the organic substances in the wastewater for the removal of nitrogen and phosphorus, In particular, it is not necessary to add an external organic carbon source, or if necessary, Since the reaction and precipitation are all carried out in each reaction tank, there is no need for a separate settling tank. Therefore, it is very economical, and the equipment and the structure of the apparatus are simple. And suggest a purification method.

However, the above two prior art techniques simply purify wastewater by repeating the SBR system. In order to grasp the quality of the polluted water to be purified by the user, the user must constantly work or monitor the sewer system to inconvenience maintenance, And the like.

In addition, a water quality sensor is installed to measure the organic water, total phosphorus, and total nitrogen, which are core water quality data, in order to manage the rivers (including the lake), the early excellent fresh water, and the sewage treatment plant discharge water.

In order to measure the various water quality data, the water quality sensors are installed according to the information. Accordingly, since various water quality sensors are provided to measure the water quality, the size of the measurement device including the water quality sensor is increased, so that it is difficult for the administrator to carry it, and it is difficult to move the water sensor. Respectively, so that there is a place and time difficulty.

Therefore, there is a method of collecting various water quality data from a single device by composing a water quality sensor in order to detect the water quality condition.

As a related art that constitutes a conventional complex water quality sensor, Japanese Patent Application Laid-Open No. 10-2007-0081461 entitled " Integrated water quality reduction device "

The related art includes a measurement unit having a plurality of measurement sensors for measuring water quality related information of water, and a controller connected to each of the plurality of measurement sensors to receive information on water quality related information of the water, And a control unit for controlling operations of the measuring unit and the data collecting unit and controlling the operation of the measuring unit and the data collecting unit based on information processed by the data collecting unit, To the controller unit via the data communication with the external device, and transmits a control command through the PLC to the measurement unit, the data collection unit, and the controller unit using the transmitted information And displays the information transmitted through the controller and the controller Wherein the water quality related information of the water is selected from the group consisting of hydrogen ion concentration (pH), redox potential (ORP), dissolved oxygen (DO), electric conductivity (conductivity) Wherein at least one of a material concentration (MLSS), a suspended substance concentration (SS), a turbidity, sodium, and silica is present in the data receiving unit, And a sensor connection terminal directly connected to the plurality of measurement sensors, wherein the sensor connection terminal is connected directly to the plurality of measurement sensors, The controller unit includes a switch unit for turning on and off the power supply and a period display unit for displaying a collection period of the water quality related information of the water set in advance, Receiving display unit for indicating whether or not data is transmitted to the data collecting unit and an analog terminal of 4 to 20 mA if the water quality related information of the water received from the data receiving unit or the data collecting unit is an analog signal, And a data communication link having a signal receiving terminal for receiving digital signals of RS232 or RS485 in the case of a digital signal, wherein the data display unit comprises: an integrated water quality remote controller having an calibration unit, Surveillance devices are presented.

However, the above-mentioned related art has a problem that a variety of water quality data can be measured by using the water quality sensor in combination, but the size of the monitoring device due to diversification of the water quality sensor is increased, and thus the mobility and portability of the device are remarkably decreased.

Also, as a prior art, there is a " integrated water quality remote monitoring apparatus "

The present invention relates to an integrated water quality remote monitoring apparatus which is small in size and easy to manage an inlet pipe and a drain pipe without being restricted by the installation place, and can save electric power. That is, the present invention provides a monolithic water quality remote monitoring apparatus for receiving sewage and remotely monitoring water quality, the monolithic water quality remote monitoring apparatus comprising: a circulation channel for providing a channel through which the sewage can be moved; And a control unit for controlling an internal temperature of the monitoring apparatus, wherein the circulation path is configured to perform heat exchange with the internal air of the integrated water quality remote monitoring apparatus through sewer water traveling through the circulation path, .

However, the conventional technique has a problem in that it can not measure various water quality data because the water quality sensor can not be constructed in a complex manner due to its small size.

Furthermore, such prior art techniques require a lot of land for each step for sewage treatment, and there is a problem in that the operator must manage the sewage in the closed space without observing the state of each step.

The housing 10 is provided with an inlet 11 through which wastewater flows and a discharge 13 through which the introduced wastewater is purified and discharged. The housing 10 is made of one container, And a plurality of wheels may be provided at the lower portion to improve the convenience of movement. However, the scope of the right should not be construed as limiting.

The housing 10 further includes a SBR (Sequencing Batch Reactor) reaction unit 20 for purifying the wastewater flowing into the housing 10.

The SBR reaction unit 20 uses the SBR process used to purify contaminated water,

The SBR (Sequencing Batch Reactor) is a time-based concept of the activated sludge process. It can remove nitrogen and phosphorus under anaerobic, anoxic, and aerobic conditions without separate reactors, recycle lines and clarifiers. It is a technique that performs steps fill, mix, aerate, idle, settle, and decant in one reaction tank.

However, when the SBR reaction unit 20 is used, there may arise a problem that the operation management of the sewage in the closed space can not be performed by the administrator without directly observing the processing state of each step.

Therefore, the present invention further includes an LOC water quality measurement unit for measuring the quality of the polluted water in the SBR reaction unit 20 in order to solve such a problem.

More specifically, the LOC (Lab-On-a-Chip) water quality measurement unit 30 measures the pH, EC, DO, turbidity, water temperature, DOC, nitrate, nitrite, phosphate, ammonia, TN, And an LOC sensor unit 31 for measuring the LOC.

The LOC is a type of biochip, which means that a laboratory is placed on a single nail-sized chip by integrating semiconductor technology, nanotechnology, and biotechnology. It is also called 'microfluidic chip'. 'Biochip' refers to a biological microchip capable of reacting DNA, proteins, other chemicals, and biological samples on a substrate made of glass, silicon or plastic to obtain various kinds of information.

LOC is made of materials such as plastic, glass, and silicon (silicon) to make fine channels of nano (less than one billionth of a liter)

This is a chip that enables quick substitution of experiments or research processes that can be done in conventional laboratories with only a small amount of samples or samples. In addition, various materials such as glass, quartz, plastic, and silicone are used to make micro-channels with narrow hair thickness inside the chip, so that various experiments and diagnoses can be made. This chip is a process in which a very small amount of laboratory liquid enters the microchannel of the chip and causes the liquid to pass through the electric signal or fine compressor to the reaction chamber and cause the liquid to react with the chemical substance generating the fluorescent signal again in the reaction chamber Use the principle of computer analysis.

In addition, LOC is attracting attention as a next-generation diagnostic device. Using this chip, it is possible to diagnose various cancers and measure cell count of red blood cells and white blood cells. It is a high-value-added product that can expand applications to a variety of fields such as livestock and the environment. Since 2000, biotechnology has been rapidly gaining attention. It is possible to rapidly carry out the experimental research process with only a trace amount of sample or sample, and it is developed as a car sedan diagnosis o analyzer in various fields such as medicine, biotechnology, environment.

In the present invention, the LOC water quality measuring unit 30 is provided with the LOC sensor unit 31 as described above. The sensor unit 31 may measure pH, EC, DO, turbidity, water temperature, DOC, (LOC) -based sensor unit 31 which is composed of all of TN, TP, and BOD software sensors such as Nitrite, Phosphate, Ammonia, etc., and measures the water quality by contacting the sensors with the sample ,

The LOC technology based sensor unit 31 is smaller in size based on the LOC than the conventional sensor, so that the size of the sensor is not increased even if it is composed of two or more sensors for measuring pH, EC, DO, turbidity, Water quality data can be measured in a complex way.

The measured water quality data can be transmitted to the manager's mobile device or an external server or both of them through the communication unit 40. The water quality data measured by the sensor unit 31 for the data transmission is transmitted to the LOC The water quality data collected by the monitoring unit provided in the water quality measurement unit 30 and transmitted to the communication unit 40 so that the communication unit 40 can transmit the water quality data wirelessly or by wire .

Therefore, the manager can always monitor the water quality of the wastewater from the outside, and at the same time, the water quality data at each stage in the SBR reaction unit 20 can be collected, thereby improving the maintenance efficiency.

Furthermore, the housing 10 may further include a controller for controlling the SBR reaction unit 20 and the LOC water quality measurement unit 30 through a control signal.

Noise may be introduced into such a control signal due to various external factors such as influences by high frequency, interference by strong electric field of the power source, and external environment (temperature, humidity, dust, etc.).

The noise introduced into the control signal rapidly increases or decreases the voltage level of the control signal, causing unstable operation of each structure, and further, it may cause malfunction and failure.

In order to solve this problem, the present invention includes a signal generation module (100) for generating a control signal in a clean state from which the possibility of noise is excluded, thereby detecting and removing noise to be introduced into the control signal in advance, Operation control is enabled.

The signal generation module 100 of the present invention is characterized in that it detects and removes noise through various steps and re-detects whether noise of the control signal is included before the control signal is finally output.

The signal generating module 100 amplifies the DC signal power by the noise amplifying unit 110 so that the noise included therein is also amplified to facilitate detection, and the noise included in the signal power source amplified by the noise detecting unit 120 is detected The noise elimination process is performed only when the noise is detected through the filter driving unit 140, thereby preventing unnecessary power consumption and operation overload, and the signal generating unit 150 And generates a clean control signal from the signal power source from which noise has been removed. The signal output unit 160 confirms whether or not the signal is cleaned and outputs the clean signal.

Hereinafter, with reference to the drawings, a detailed description of each sub-structure of the signal generation module 100, a description of an operation process thereof, and an effect thereon will be described.

The noise amplifying unit 110 includes a first amplifying circuit 111 for first amplifying the signal power source and a second amplifying circuit 112 for secondarily amplifying the signal power.

The first amplifying circuit 111 and the second amplifying circuit 112 have the same structure and each have a distribution resistor R101 connected to the (+) terminals of the amplifiers A101, A102, A101, A feedback resistor R105 R106 and a capacitor C105 connected in parallel between the output terminal and the negative terminal of the resistors R102, R103 and R104, the capacitors C101 and C102 and the amplifiers A101 and A102, ) C106.

The operation and effects of the first amplifying circuit 111 and the second amplifying circuit 112 will be described by taking the first amplifying circuit 111 as an example. The amplifier A101 includes the dividing resistors R101 and R102, R106), and a grounding resistor to operate as a non-inverting amplifier to amplify the voltage level of the signal power supply, so that the noise is also amplified to facilitate detection of noise.

In the second amplifying circuit 112, the signal power is amplified through the same process.

The noise amplifier 110 is connected between the amplifier output terminal of the first amplifier circuit 111 and the amplifier (+) terminal of the second amplifier circuit 112, The signal is firstly amplified by the first amplifying circuit 111 and the output is amplified by the second amplifying circuit 112 so that the signal power is doubly amplified so that the noise can be easily detected.

The life of the filter driver 140 can be extended through the provision of the delay circuit 124. Since the noise is generated intermittently instead of continuously and periodically, the filter driver 140 is driven and not driven It is preferable to extend the life of the filter driving unit 140 by driving the filter driving unit 140 continuously until a predetermined time elapses after the operation of the filter driving unit 140.

Since the noise can be removed in three stages through the filter unit 130 having the above-described features and features, noise can be removed more effectively than the noise filter of the related art, and a signal power source So that there is an advantage that additional commutation or DC conversion process is not required.

Although the two voltage drop diodes D501 and D502 are shown in the drawing, the voltage drop diodes D501 and D502 may be provided in a plurality of voltage drop diodes D502 and D502, respectively.

The operation and characteristics of the signal generator 150 will be described. The signal power source from which the noise is removed passes through the voltage drop diodes D501 and D502 and is converted into a voltage level suitable for the control signal.
