Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Example 1:

As shown in Figure 1, an integrated constructed wetland wastewater treatment system includes a wetland wastewater treatment unit, a wetland information collection unit, a wetland basic inspection unit, a wetland depth operation unit, and a text editing unit;

Wetland wastewater treatment unit, used for wetland self-flow purification of wetland wastewater;

Wetland information collection unit, used to collect wetland wastewater purification environmental information and wetland sludge sedimentation information and send it to the wetland foundation inspection unit;

The environmental information of wetland wastewater purification includes the external average temperature within the wetland wastewater area, the internal average temperature within the wetland wastewater area, the total plant area within the wetland wastewater area, the average density of plants per unit within the wetland wastewater area, and the wetland wastewater area. The oxygen content at the top and the oxygen content at the bottom of the wetland wastewater are composed;

The rise and fall of the external average temperature within the wetland wastewater area will affect the rise and fall of the internal average temperature within the wetland wastewater area, and the rise and fall of the internal average temperature within the wetland wastewater area will affect the growth of plants in the wetland environment, thereby affecting the wetland wastewater area. The total plant area within the range and the average density of plants within the wetland wastewater area range. When the temperature is high and low, it will affect the growth of plants in the wetland environment, and the growth of plants in the wetland environment will produce or consume oxygen, thereby affecting the growth of plants. To the oxygen content in the wetland wastewater, the size of the oxygen content will obviously affect the number of aerobic bacteria or anaerobic bacteria. The aerobic bacteria live on the top of the wetland wastewater, so the oxygen content at the top of the wetland wastewater is collected. It grows at the bottom of wetland wastewater, so there is oxygen content at the bottom of wetland wastewater. Therefore, photosynthetic plants are planted on the top of wetland wastewater, and respiration plants are planted at the bottom of wetland wastewater, and its root system needs to be developed, so that the root system can better capture and decompose wastewater.

Among them, the wetland sludge deposition information is composed of the high unit time of wetland sludge deposition, the transparency of wetland wastewater, and the influent volume of wetland wastewater;

After the wetland purification capacity reaches saturation, the more the wetland wastewater enters the liquid, the worse the wetland purification ability of solid silt, and the lower the transparency of the wetland wastewater, resulting in a poor purification effect; therefore, it is necessary to pass the wetland sludge precipitation unit time The average height, the transparency of the wetland wastewater and the liquid inflow volume of the wetland wastewater can be used to judge whether the wetland purification saturation has been reached as a whole;

Obtain the instantaneous purification amount B of wetland wastewater, where e7, e8 and e9 are instantaneous quantization factors, and the instantaneous quantization factor makes the calculated result closer to the real value, e9>e8>e7, and e9+e8+e7=7.81;

The instantaneous purification amount B of wetland wastewater is also compared with the preset value b. When B>b, no control signal is generated, otherwise, a second control signal is generated; immediately after the second control signal is generated, the water inflow is reduced and the pull rate is increased. Long time for wastewater treatment, until the instantaneous purification amount of wetland wastewater B > preset value b, so as to achieve the best wastewater purification;

The generation of the second control signal indicates that the instantaneous purification capacity of the wetland is exceeded, resulting in a rapid decrease in the transparency of the wastewater, where the transparency of the wetland wastewater is 0 < M < 1, and the higher the transparency of the wastewater, the clearer the wetland wastewater and the better the purification capacity;

When the first control signal is generated, the instantaneous purification factor A of the overall wetland environment and the instantaneous purification amount B of the wetland wastewater are sent to the wetland deep operation unit;

The specific working steps of the wetland depth evaluation unit are as follows:

The wetland in-depth operation unit receives the instantaneous purification factor A of the wetland overall environment and the instantaneous purification amount B of the wetland wastewater, and stores them to generate the historical factor of wetland overall environmental purification and the historical purification amount of the wetland wastewater;

Then, several historical factors of wetland overall environmental purification and historical purification amount of wetland wastewater are extracted to obtain the first target quantification standard deviation value AJ and the second target quantification standard deviation value BJ, respectively. Quantify the standard deviation value BJ, through the formula Zs=|AJ-BJ|/(AJ+BJ), get the wetland environment purification saturation adaptation degree Zs;

The purification saturation adaptation degree Zs of the wetland environment is also compared with the expected range value zq. When zs=zq, the first evaluation signal under the non-optimal purification environment is generated; otherwise, the first evaluation signal under the non-optimal purification environment is generated. 2. Evaluation signal;

The generated wetland environment purification saturation adaptation degree Zs, the first evaluation signal and the second evaluation signal are also sent to the text editing unit:

When the text editing unit receives the overall real evaluation value zs of the wetland and the first evaluation signal, it immediately edits the first evaluation text, and the first evaluation text is "the wetland environment purification saturation adaptation degree of the wetland under the non-optimal purification environment is Zs, At this time, the wetland environment is in a state of dynamic purification and saturation for a long time”;

When the text editing module receives the overall real evaluation value zs of the wetland and the second evaluation signal, it immediately edits the second evaluation text, and the second evaluation text is "the wetland environment purification saturation adaptation degree of the wetland under the non-optimal purification environment is Zs, At this time, the wetland environment is in a state of non-dynamic purification and saturation for a long time”; the non-optimal purification environment usually refers to the chain reaction caused by colder or hotter;

And send the edited first evaluation text and the second evaluation text to the display terminal for display;

The second evaluation text enables the staff to appropriately adjust the corresponding countermeasures, for example, appropriate increase or decrease of plants, increase or decrease of temperature, etc., to ensure that the wetland is in a saturated purification state in a non-optimal purification environment;

Working principle: The present invention sets up a wetland wastewater treatment unit, a wetland information collection unit, a wetland basic inspection unit, a wetland in-depth operation unit and a text editing unit. Information collection, analysis, comparison and processing of environmental parameters, and cooperate with the collection of wetland purification capacity, so as to realize the organic combination of wetland environmental parameters and wetland purification capacity, so that the wetland can reach the best saturation state, thereby improving the efficiency and capacity of purification, solving the problem of Traditional wetlands cannot detect and process environmental parameters, and cannot make the purification of wetlands in a real-time saturation state, resulting in the problem of low efficiency of transmission wetland purification.
