[0046] S12: Conduct water quality testing on the sewage in the biological reaction chamber to obtain the microbial content index of the sewage.

[0047] A water quality detection component is arranged in the biological reaction chamber, and the sewage inside the biological reaction chamber is quickly detected based on the water quality detection component to obtain the water quality of the sewage inside the biological reaction chamber, so as to adjust the proportion of the biological bacteria solution according to the water quality inside the biological reaction chamber, so that the biological bacteria solution can fully react with the sewage inside the biological reaction chamber, thereby improving the reaction efficiency.

[0048] S13: Calculate the theoretical value of the reaction gas of the sewage by combining the sewage volume and the microbial content index.

[0049] Specifically, by obtaining the sewage volume and the microbial content index of the sewage, the theoretical value of the reaction gas that can be obtained after the sewage and the microbial solution are reacted is calculated. When the sewage and the microbial solution are reacted, the bioreactor chamber is configured as a closed space. Based on the theoretical value of the reaction gas of the sewage, the air pressure change inside the bioreactor chamber can be estimated, so as to adjust the reaction treatment time of the sewage in the bioreactor chamber according to the amplitude of the gas change inside the bioreactor chamber.

[0058] Embodiment 2:

[0059] Figure 2 A flow chart of a method for treating reclaimed water according to an embodiment of the present invention is shown;

[0060] S101: Obtain the flow rate of sewage.

[0061] The water flow rate of sewage transportation is obtained, a flow meter is set at the connection position between the sewage input end and the biological reaction chamber, and the water flow rate of sewage transportation is measured and recorded based on the flow meter.

[0062] Furthermore, a propeller flowmeter is provided in the pipe at the sewage input end. The propeller of the propeller flowmeter rotates under the push of the sewage flow, so as to obtain the rotation rate of the propeller under the action of the sewage flow. The flow rate of the sewage flow can be converted based on the propeller rotation rate of the propeller flowmeter.

[0063] Furthermore, the cross-sectional area of ​​the sewage conveying pipeline is stored in the reclaimed water purification treatment device so as to convert the injection volume of the sewage into the biological reaction chamber in combination with the sewage conveying flow rate and the sewage conveying time.

[0064] S102: Obtain the time when sewage is injected into the reaction chamber.

[0065] The duration of sewage input into the biological reaction chamber is recorded. An electric valve is provided at the connection position between the sewage input end and the biological reaction chamber. When the reclaimed water purification treatment device inputs sewage into the biological reaction chamber, the duration of the electric valve opening state is recorded, and the duration is marked as the continuous delivery time of sewage to the biological reaction chamber.

[0066] Based on the delivery time of sewage to the bioreactor chamber and the flow rate of sewage, the amount of sewage injected into the bioreactor chamber can be converted, so as to adjust the configuration of the microbial solution according to the sewage capacity in the bioreactor chamber.

[0067] S103: Obtain the sewage volume in the biological reaction chamber.

[0068] The sewage injection volume is calculated by combining the water flow rate and the duration, and converted into a first injection volume.

[0069] Specifically, the flow rate of the sewage from the sewage input end to the biological reaction chamber is obtained by a flow meter, and the amount of sewage injected into the biological reaction chamber is obtained in combination with the cross-sectional area of ​​the sewage transportation and the duration of the sewage transportation.

[0070] The calculation formula of the first injection volume of the bioreactor chamber is:

[0071] V1=t1*v1*s1;

[0072] Among them, V1 is the first injection volume, t1 is the continuous sewage injection time, v1 is the sewage flow velocity, and s1 is the sewage transportation cross-sectional area.

[0073] Furthermore, the continuous sewage injection time is the standard water injection time set inside the reclaimed water purification treatment device, so that the sewage input end can continuously input a preset amount of sewage into the biological reaction chamber so that the sewage inside the biological reaction chamber can undergo microbial reaction treatment.

[0074] After the transportation of sewage stops, the weight of the sewage in the biological reaction chamber is obtained based on the gravity sensor of the biological reaction chamber, and the second injection volume of the sewage is converted according to the weight of the sewage.

[0075] When the sewage input end stops inputting sewage into the biological reaction chamber, the gravity sensor inside the sewage reaction chamber obtains the pressure exerted by the sewage liquid inside the biological reaction chamber on the bottom of the biological reaction chamber, and outputs the weight of the sewage inside the biological reaction chamber.

[0076] Since the sewage is domestic sewage, the water density of the sewage is about 1g / cm 3 , combined with the weight of the sewage, the volume of the sewage inside the biological reaction chamber can be calculated, thereby obtaining the second injection volume:

[0077] V2=m / ρ;

[0078] Where V2 is the second injection volume, m is the weight of sewage inside the bioreactor chamber, and ρ is the sewage density, ρ = 1 g / cm 3 .

[0079] The first injection volume and the second injection volume are averaged to obtain the sewage volume in the biological reaction chamber. By calculating the average of the first injection volume and the second injection volume, and taking the average of the first injection volume and the second injection volume as the sewage volume in the biological reaction chamber, the accuracy of calculating the gas change amount inside the biological reaction chamber can be improved, thereby improving the purification treatment effect of the biological reaction chamber on the sewage.

[0080] S104: Detect the sewage quality in the biological reaction chamber.

[0081] Specifically, a water quality detection component is provided in the bioreactor chamber, and the sewage entering the bioreactor chamber is rapidly tested by the water quality detection component so as to configure a corresponding microbial solution according to the sewage water quality of the bioreactor chamber.

[0082] Specifically, the sewage in the microbial reaction chamber is sampled based on the probe to obtain a water quality sample. A sampling probe is arranged inside the biological reaction chamber, and a test solution is stored inside the probe. The sewage sample inside the biological reaction chamber is sucked by the probe, and the sewage sample and the test solution are contacted and reacted, so that the microorganisms in the sewage sample react with the biological enzymes in the test solution, and the sewage water quality inside the biological reaction chamber is obtained according to the reaction results.

[0083] Based on the biological enzyme on the probe, the water quality sample is subjected to an explicit microbial reaction, and the water quality microbial content index is output according to the reaction result. The fluorescent enzyme probe reacts, combines or adsorbs with microbial metabolites, enzyme activity, cell wall and other characteristics, thereby realizing quantitative detection of microorganisms in the sample sewage. Based on the reaction between the fluorescent enzyme and the microorganisms in the sewage and the intensity of the light color after the reaction, the explicit detection of the sewage water quality is achieved, so that the water quality detection component can effectively detect the water quality of the sewage inside the biological reaction chamber.

[0084] Specifically, the acidity and alkalinity of the water sample is tested based on the probe to obtain the acidity and alkalinity index of the water quality. By setting phenolphthalein test paper on the probe, the acidity and alkalinity of the sewage sample obtained by the probe is tested based on the phenolphthalein test paper to obtain the acidity and alkalinity of the sewage inside the biological reaction chamber. According to the acidity and alkalinity of the sewage in the biological reaction chamber, the corresponding microbial solution is configured so that the microbial solution can fully react and decompose the sewage inside the biological reaction chamber, thereby realizing the purification of the sewage.

[0085] Furthermore, the water quality of the sewage is tested by the water quality testing component inside the biological reaction chamber, and the microbial content index of the sewage is obtained, and the biological colonies corresponding to the active environment are selected in combination with the acidity and alkalinity of the sewage. In addition, several kinds of biological colonies are deployed according to the water quality of the sewage inside the biological reaction chamber, so that the biological bacterial solution can be efficiently decomposed and purified according to the microbial index of the sewage, thereby further improving the effect of the reclaimed water purification treatment.

[0086] S105: Prepare biological bacteria solution.

[0087] According to the microbial content index, several biological colonies are matched and the mixing ratio of the several biological colonies is configured.

[0088] Specifically, according to the detection result of the water quality detection component on the sewage inside the biological reaction chamber, the microbial index content of the sewage is output. According to the microbial species of the biological sewage, a detection biological enzyme corresponding to the microbial species is configured in the reclaimed water purification treatment device, so that the water quality detection component of the biological reaction chamber can identify the microbial species of the sewage, and according to the degree of color development reaction between the corresponding microorganism and the biological enzyme, the content of various microbial species in the sewage inside the biological reaction chamber is obtained, that is, the microbial content index of the sewage in the biological reaction chamber is obtained.

[0089] Furthermore, based on the microbial content index of the water quality detection component, the grey water purification treatment device can configure the microbial colonies corresponding to the purification treatment according to the microbial content index, thereby configuring a microbial solution that meets the requirements of the grey water purification treatment.

[0090] Furthermore, the microbial indicators in the sewage include bacteria, Escherichia coli, Salmonella, Shigella, Vibrio cholerae, and activated sludge protozoa such as echinocera and Acanthocera.

[0091] S106: Adjust the amount of biological bacteria solution added.

[0092] According to the sewage volume combined with the microbial content index, a preset volume of biological bacteria solution is input, and according to the sewage volume inside the biological reaction chamber, the configuration ratio of sewage to biological bacteria solution is set to: 10:1. The biological bacteria solution is input into the biological reaction chamber according to the configuration ratio, and the mixed liquid of the microbial solution and the sewage is continuously stirred so that the microbial solution and the sewage can fully react.

[0093] The amount of reaction gas generated in the bioreactor chamber is recorded within a first preset time to obtain a change in reaction gas pressure.

[0094] The sewage inside the biological reaction chamber is reacted with the microbial solution, and the amount of reaction gas generated inside the biological reaction chamber is obtained after a first preset time. The configured biological solution is reacted with the sewage, and the change in the reaction efficiency of the microbial solution and the sewage is obtained based on the amount of gas generated after the reaction.

[0095] S107: Calculate the theoretical value of the reaction gas.

[0096] Query the reaction time and reaction gas generation per unit volume of sewage according to the microbial content index;

[0097] The amount of gas generated after the sewage reacts is calculated according to the volume of the sewage, and a theoretical value of the reaction gas of the sewage is obtained.

[0098] According to the chemical reaction formula of the anaerobic digestion process of organic matter, the gas production per unit mass of various microbial indicators can be calculated, and according to the reaction relationship between the microbial solution and the sewage volume in the biological reaction chamber, the gas production of the sewage volume and the microbial solution can be calculated. Due to the complex organic components of domestic sewage, the gas production after the sewage volume and the microbial solution are completely reacted can be calculated based on the COD (chemical oxygen demand) value.

[0099] Furthermore, based on the theoretical value of the reaction gas after the sewage reaction and in combination with the initial air pressure in the closed state of the biological reaction chamber, the theoretical change value of the air pressure inside the biological reaction chamber can be obtained.

[0100] S108: Obtaining the actual change in reaction gas.

[0101] The reaction change rate of the sewage in the biological reaction chamber is calculated according to the reaction gas pressure change, and the reaction gas change amount in the biological reaction chamber within the first preset time is obtained based on the pressure sensor inside the biological reaction chamber, thereby obtaining the pressure change rate of the biological reaction chamber within the first preset time.

[0102] Specifically, the first preset time is divided into a number of unit time periods, and the air pressure detection data of each unit time is obtained according to the air pressure sensor inside the bioreactor chamber, so as to obtain the change rate of the air pressure data inside the bioreactor chamber.

[0103] The calculation formula for the air pressure change rate of the microbial decomposition reaction during the first preset time is:

[0104]

[0105] Among them, ΔP is the pressure change per unit time, Δt is the unit time, and t i+1 is the i+1th moment, t i is the i-th moment, P i+1 is the air pressure value at the i+1th moment, P i is the air pressure value at the i-th moment.

[0106] Furthermore, the pressure change rates corresponding to a number of time periods are obtained within the first preset time, and the change rate of the pressure data in the bioreactor chamber is obtained according to the change trends of the pressure change rates in the number of time periods.

[0107] Furthermore, the first preset time is set according to the detection data of the air pressure sensor inside the bioreactor chamber. When the change amplitude of the air pressure sensor value tends to be flat, the current time period is marked as the first preset time, and the air pressure data inside the bioreactor chamber is analyzed and calculated.

[0108] S109: Correct the theoretical value of the reaction gas.

[0109] The theoretical value of the reaction gas is corrected according to the reaction change rate to obtain the amount of reaction gas in the biological reaction chamber.

[0110] Based on the changing trends of several sections of the air pressure change rate, a stable value of the air pressure change rate per unit time is obtained, and according to the stable value of the air pressure change rate.

[0111] Calculating the reaction gas volume according to the pressure change value inside the bioreactor chamber within the first preset time, and converting it into the sewage reaction volume, performing a difference calculation based on the sewage volume and the sewage reaction volume, obtaining the sewage to-be-reacted volume, calculating the volume of the gas to-be-generated in the bioreactor chamber in combination with the stable value of the pressure change rate, obtaining an approximate reaction gas amount in the bioreactor chamber based on the volume of the gas to-be-generated and the reaction gas volume, comparing the approximate reaction gas amount with a theoretical value of the reaction gas, and if the approximate reaction gas amount is greater than the theoretical value of the reaction gas, marking the approximate reaction gas amount as the reaction gas amount in the bioreactor chamber;

[0112] If the approximate reaction gas amount is less than the reaction gas theoretical value, the reaction gas theoretical value is marked as the reaction gas amount in the bioreactor chamber, thereby ensuring that the sewage in the bioreactor chamber reacts completely with the microbial solution.

[0113] S110: Setting the air pressure threshold of the bioreactor valve.

[0114] The changed air pressure value in the bioreactor chamber is converted based on the amount of reaction gas in the bioreactor chamber, and the changed air pressure value is set as the air pressure threshold of the bioreactor chamber valve. When the internal air pressure of the bioreactor chamber reaches the air pressure threshold, the valve of the bioreactor chamber can be automatically opened to realize the transportation of purified reclaimed water.
