In recent years, the amount of sewage discharged is growing rapidly, but how to effectively monitor and manage the discharge of sewage has become an important problem for government departments. With the development of the economy, people's pursuit of interests tends to be at the expense of the environment, such as sewage discharged from factories and wastewater for domestic use. The discharge of these sewages is often unregulated because it often requires a lot of manpower and material resources, and the supervision costs are very high. high.

Effective monitoring of sewage can facilitate the remediation of sewage discharge. However, in the prior art, the monitoring of sewage is often found to be abnormal when the quality of the discharged sewage has exceeded the standard, and cannot be found at the same time as the discharge, and the sewage discharged has already caused an environment to the environment. Pollution, so that it is impossible to timely and effectively control the discharge of sewage, there is a serious lag. For example, it is too late to discharge sewage into rivers or lakes when it is found that water in rivers or lakes is polluted. At this time, it is very difficult to control rivers or lakes, and the cost of treatment will be higher than the cost of supervision. It is often difficult to control the water body of a river or a lake. Even if a lot of manpower and material resources are used to control it, the effect is often not satisfactory.

Detailed ways

In the following description, for purposes of explanation and description, reference However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, circuits, and methods are omitted so as not to obscure the description of the invention.

In the present invention, the sewage parameters include a flow rate v, a chemical oxygen demand COD, a biochemical oxygen demand BOD5, a suspension SS, a nitrogen content, and a pH.

Chemical Oxygen Demand COD is a commonly used comprehensive indicator for assessing the degree of water pollution. It is the abbreviation of English chemical oxygen demand. The Chinese name is “chemical oxygen demand” or “chemical oxygen demand”, which refers to the oxidative decomposition of reducing substances (such as organic matter) in water by chemical oxidants (such as potassium dichromate). The amount of oxygen consumed, which reflects the extent to which water is contaminated with reducing substances. Since organic matter is the most common reducing substance in water, COD reflects to some extent the extent to which water is contaminated by organic matter. The higher the COD, the more serious the pollution. China's "Surface Water Environmental Quality Standards" stipulates that the COD concentration of drinking water sources should be less than 15 mg / liter, and the general landscape water COD concentration should be less than 40 mg / liter. The higher the COD, the higher the content of reducing substances (such as organic matter) in the water, and the reducing substances can be lowered. The dissolved oxygen content in low water bodies causes aquatic organisms to be deprived of oxygen and even die, and the water quality is stinky. In addition, organic substances such as benzene and phenol are also highly toxic, causing direct damage to aquatic organisms and humans. Therefore, China regards COD as a key indicator of water pollutants.

BOD (abbreviation of Biochemical Oxygen Demand) means: biochemical oxygen demand or biochemical oxygen demand, a comprehensive indication of the content of aerobic pollutants such as organic matter in water, which indicates that organic matter in water is oxidized by the biochemical action of microorganisms. The total amount of dissolved oxygen in the water consumed by decomposition and mineralization or gasification is expressed in milligrams per liter. The higher the value, the more organic pollutants in the water and the more serious the pollution. In order to make the test data comparable, a time period is generally specified. During this time, the microorganisms are cultured with water at a certain temperature, and the dissolved oxygen consumption in the water is measured. Generally, five days are used, which is called five-day biochemistry. Oxygen demand, recorded as BOD5. The larger the value, the more organic matter is contained in the water, and the more serious the pollution. The biochemical oxygen demand is calculated as follows:

BOD (mg / L) = (D1-D2) / P;

Wherein D1 represents the initial dissolved oxygen (mg/L) of the diluted water sample, and D2 represents the dissolved oxygen (mg/L) of the diluted water sample cultured in a 20 ° C incubator for 5 days, P = water sample volume (mL) / The final volume (mL) of the water sample after dilution.

FIG. 1 is a schematic flow chart of a sewage monitoring and management method provided by an embodiment of the present invention. The execution body of the method shown in FIG. 1 may be a server, and the method includes:

S110, obtaining a current sewage parameter value of each sewage point and a current valve opening degree of the corresponding discharge valve of the sewage point;

It should be noted that, in this embodiment, a sewage parameter detecting device is disposed at each of the sewage points, and the sewage parameter sensing signal at the sewage point is collected, and the sewage is read according to the sewage parameter sensing signal. The current sewage parameter value of the point of discharge of sewage.

An electric valve is further disposed at each of the sewage points for controlling sewage discharge at each of the sewage points, wherein the opening degree of the electric valve can be continuously adjusted to realize sewage of the sewage point Precise control of emissions.

In this embodiment, the specific opening degree of the valve corresponding to the drain point is obtained by collecting the driving current of the valve corresponding to the drain point and reading the current opening degree of the valve according to the driving current. Since the opening degree of the electric valve and the driving current have a corresponding relationship, the current valve opening degree of the electric valve can be accurately obtained by collecting the driving current of the electric valve, which is not only very accurate, but also very convenient, and can be directly obtained remotely. It is convenient for the background monitoring platform to know in real time the valve opening degree of each corresponding discharge point corresponding to the valve.

In practice, each of the smear point information and the corresponding user information are associated with each other in advance, the smear point information includes location information of the smear point and a unique ID number of the smear point, and the user information includes a user name, at least one contact, and contact number. In this way, when the background monitoring platform receives the sewage parameter and/or alarm information of a sewage point, the corresponding user name and contact person can be accurately known, so that the environmental protection function department can contact the corresponding user and feed back relevant information.

S120: Analyze a pollution level according to a current sewage parameter value of each of the sewage points, and adjust a valve opening degree of the corresponding discharge point of the sewage discharge point according to the pollution level to control sewage discharge of the sewage discharge point.

The pollution level of the sewage is determined by the current sewage parameter value, and the valve opening degree of the corresponding discharge point of the sewage discharge point is adjusted according to the pollution level, so that the valve corresponding to the sewage discharge point can be accurately controlled to ensure that the natural water body discharged after the sewage is discharged can Through self-repair, a virtuous cycle can be achieved to avoid the water body discharged into the sewage cannot be self-repaired due to excessive discharge of sewage or excessive discharge of sewage, and cause complete deterioration of the water body and damage to the environment.

The sewage monitoring and management method provided by the invention obtains the current sewage parameter value of each sewage point, analyzes the pollution level according to the current pollution parameter value, and controls the opening degree of the valve according to the pollution level, thereby realizing effective sewage discharge to the sewage point. And precise control, to avoid the environmental pollution and water body deterioration caused by the random discharge of sewage, automatic monitoring, reducing the labor intensity and supervision costs, green and low carbon, energy saving and environmental protection.

Preferably, as another embodiment of the present invention, on the basis of the embodiment shown in FIG. 1, as shown in FIG. 2, in this embodiment, the valve opening degree of the corresponding valve of the sewage discharge point is adjusted according to the pollution level. Specific implementations include:

S210. Compare the current sewage parameter value with a corresponding pre-stored standard sewage parameter value, and calculate a difference between the current sewage parameter value of the sewage point and the corresponding standard sewage parameter value.

In practice, the standard sewage parameter value is set in advance for each sewage parameter, and then each current sewage parameter value obtained is compared with the corresponding standard sewage parameter value, and the current sewage parameter value of each sewage parameter can be obtained. The difference from the corresponding standard sewage parameter value.

S220: Calculate a comprehensive pollution index value of the sewage disposal point according to a difference between the current sewage parameter value and a corresponding standard sewage parameter value and a weight corresponding to each preset sewage parameter.

It should be emphasized that in all sewage parameters, different sewage parameters have different effects on the environment. For example, chemical oxygen demand (COD) and biochemical oxygen demand (ODD) have a greater impact on the environment, so the corresponding weights are correspondingly larger. The weight of each sewage parameter is pre-set to calculate the discharge point. The comprehensive pollution index value can reflect the overall impact of the sewage on the environment as a basis for whether or not to meet the emission standards.

In addition, the weight of each sewage parameter is set according to its impact on the environment, and is adjusted for different emission standards or different types of sewage. such as:

X=n1*A1+...+ni*Ai+...+nm*Am

Where X represents the comprehensive pollution index value, ni represents the weight of the i-th pollution parameter, Ai represents the pollution parameter value of the i-th pollution parameter, and n1+...ni+...nm=1.

Since the pollution level and the corresponding comprehensive pollution index value range have been pre-divided in the above steps, it is first determined whether the comprehensive pollution index value is within the standard pollution index range, and if so, the discharged sewage is up to standard, and the pollution level is determined. Zero, when the comprehensive pollution index value exceeds the standard pollution index range, it indicates that the discharged sewage does not meet the standard, which will cause pollution to the water body. At this time, by calculating the deviation between the comprehensive pollution index value and the standard pollution index range, Reflecting the degree of pollution of the discharged sewage, the corresponding pollution level can be determined by the range of the pollution level to which the deviation between the comprehensive pollution index value and the standard pollution index range belongs. It should be noted that the deviation value of the comprehensive pollution index value and the standard pollution index range is judged here as the reference upper limit of the standard pollution index range.

Specifically, the sewage can be divided into multiple pollution levels according to different emission standards or different types of sewage, and each comprehensive pollution index range corresponds to one pollution level. For example, the pollution level can be divided into five levels according to different emission standards, and each pollution level corresponds to an electric valve opening interval. Of course, it is also possible to divide more or less pollution levels, which can be adjusted according to actual conditions, and there is no limitation here.

S240. Read a valve opening interval corresponding to the pollution level, and adjust the valve to any opening value in the corresponding valve opening interval.

Here, each of the pollution levels corresponds to a valve opening interval correspondingly, so that the set valve opening interval can be accurately read according to the pollution level, and then the valve is adjusted to the corresponding Any opening value in the valve opening interval to achieve sewage discharge at the sewage point.

Preferably, as another embodiment of the present invention, in this embodiment, a valve opening function is established according to the comprehensive pollution index in each preset valve opening interval, and the function expression is as follows:

Where x represents the comprehensive pollution index, y represents the valve opening degree, and the two are inversely proportional, the valve opening degree decreases as the comprehensive pollution index increases, and when the comprehensive pollution index x is zero, The valve opening degree y is 100%; when the comprehensive pollution index x reaches the critical threshold value k, the valve opening degree y is zero, that is, the valve is closed, and the user is prohibited from continuing to discharge more than the sewage; when the comprehensive pollution index x When it is at any value between 0-k, the valve opening value y corresponding to the comprehensive pollution index x is read according to the valve opening function, and the valve is continuously adjusted to the target valve opening value. In this way, continuous adjustment of the valve can be realized according to the comprehensive pollution index x, and continuous and precise control of the valve opening degree can be realized.

Preferably, as another embodiment of the present invention, in the embodiment, the method further includes performing a correction process on the opening degree of the valve, specifically: reading an actual opening value of the valve, and Comparing the actual opening value with the valve opening interval, and when the actual opening value of the valve exceeds the valve opening interval, according to the actual opening value of the valve and the valve opening interval The deviation value generates a correction command and is sent to the corresponding valve.

In the above embodiment, the opening of the valve can be ensured by performing the opening correction process on the valve. The degree interval is matched with the corresponding pollution level to avoid the control of the sewage discharge due to the deviation of the opening control precision caused by the valve itself, and the opening degree correction processing can be performed on the actual door. When the opening value is deviated from the valve opening interval, the valve opening degree is controlled to be within the expected opening interval.

Preferably, as another embodiment of the present invention, in this embodiment, when any sewage parameter value reaches a limit condition, the valve corresponding to the sewage discharge point is completely closed, and an alarm information is generated, and the alarm information is sent. The user terminal; wherein the limiting condition is that any pollution parameter in the sewage discharged from the sewage discharge point exceeds a corresponding early warning threshold for a preset time.

Here, the limiting condition is that any pollution parameter in the sewage discharged from the sewage discharge point continues to exceed the corresponding early warning threshold within a set time range, thereby preventing the sewage parameter detected due to uneven sewage in the sewage discharge process Fluctuations and false positives occur. When any pollution parameter continues to exceed the corresponding warning threshold within the set time range, it can be confirmed that the discharged sewage has serious excessive behavior, and it is necessary to directly control the corresponding discharge point. The valve is completely closed, and it is forbidden to discharge the uncontaminated sewage to cause irreparable damage to the natural water body. At the same time, the alarm information will be uploaded to the user terminal, and the user will be notified to stop the discharge immediately and take measures.

Preferably, as an embodiment of the present invention, in the embodiment, the method further includes: analyzing the alarm information uploaded by each of the sewage points every predetermined time, and obtaining the emission frequency of the sewage discharge point exceeding the standard Degree, and calculate the environmental protection level of the user corresponding to the discharge point according to the excess emission level and save.

Preferably, as an embodiment of the present invention, in the embodiment, the method further includes: when the discharge point exceeding the standard discharge frequency exceeds the preset safety frequency, according to the discharge limit exceeding the standard discharge frequency and the pre-standard The administrative penalty level is generated by the administrative penalty level described by the difference between the safety frequencies, and is sent to the corresponding user terminal.

In the above embodiment, by monitoring the frequency of the user's exceeding the standard, the user's over-standard discharge line can be restrained, and the difference between the frequency of the excess standard and the preset safety frequency is used as a punishment. Based on the principle, the user is responsible for the illegal discharge responsibility that is appropriate to the degree of behavior, and enhances the user's environmental awareness.

S130, dividing all the sewage discharge points according to the area, detecting the environmental parameters in the corresponding area, calculating the environmental comprehensive index of each area, and determining whether the environment in the area is affected by the sewage discharged by the sewage disposal point according to the environmental comprehensive index. Wherein, the environmental comprehensive index is obtained by adding each environmental parameter to a corresponding weight product.

Here, according to the environmental comprehensive index, it is judged whether the environment in the area is discharged by the sewage discharge point The specific realization of the impact is: when the environmental comprehensive index of any region reaches the set threshold, the change trend of the environmental comprehensive index in the corresponding region is identified, and if the environmental comprehensive index in the corresponding region rises and exceeds the corresponding preset threshold, then the determination is made. The environment in the corresponding area is affected by the discharge of sewage from the discharge point.

In addition, the environmental comprehensive index is simplified into a single conceptual index value by the concentration of air pollutants such as soot, total suspended particulate matter, respirable suspended particulate matter (floating dust), nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone, volatile organic compounds, and the like. It can be graded to characterize air pollution levels and air quality conditions and is suitable for representing short-term air quality conditions and trends.

It should be pointed out that all the sewage points are divided according to the area. On the one hand, it is convenient to effectively manage all the sewage points. When the local environment is affected, it is first judged which environment is affected, and then the area is judged. Whether the discharge point inside the discharge point is abnormal; on the other hand, it can effectively monitor the local area in the air to accurately find the source of pollution.

Here, if the environmental comprehensive index value rises and exceeds the corresponding preset threshold value, it indicates that the environmental comprehensive index value rises from the original normal range to exceed the corresponding preset threshold value due to the influence of the sewage discharged by the sewage discharge point, indicating the sewage discharge point. The local environment within the scope is obviously affected by sewage discharge. At this time, this information can be fed back to the environmental protection function department, and the environmental protection functional department is notified to take immediate measures to avoid further damage to the local environment due to sewage discharge.
