[0002] Solid content of sewage refers to the mass or volume ratio of solid matter contained in a unit volume of sewage. These solid substances include suspended matter such as organic matter, inorganic matter, and organisms. Solid content of sewage is one of the important parameters reflecting sewage quality, and its level directly affects the effect of sewage treatment and environmental protection. High solid content of sewage may cause turbidity of water, affect the transparency and ornamental value of water, and also have a negative impact on the normal growth and life of aquatic organisms.

[0003] In concrete production enterprises, a large amount of sewage is generated due to flushing in various occasions. At present, most enterprises adopt multi-stage sedimentation and filtration of sewage, and then treat it by mechanical compression.

[0048] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0049] First embodiment

[0050] like Figure 1 and Figure 2 As shown, the sewage solid content detection equipment includes:

[0051] A detection cylinder 110, wherein the detection cylinder 110 is used to introduce a first preset volume of detection sewage;

[0052] A weighing unit 120, the weighing unit 120 is connected to the detection cylinder 110, and is used to weigh the detection sewage to obtain the weight of the detection sewage;

[0053] The detection unit 130 communicates with the weighing unit 120, and the detection unit 130 pre-records the weight of the detection cylinder and the weight of the clean water of a second preset volume, the first preset volume is equal to the second preset volume, and the detection unit 130 calculates the solid content of the detection sewage according to the weight of the detection cylinder, the weight of the clean water, and the weight of the detection sewage.

[0054] The volume of the detection cylinder 110 and the liquid level sensor 113 installed inside the detection cylinder 110 determine the first preset volume value that can carry the detection sewage. It can be seen that the detection cylinder 110 can define the volume of the detection sewage. Then the weighing unit 120 weighs the first preset volume of the detection sewage discharged from the detection cylinder 110 to obtain the weight of the detection sewage. Finally, the detection unit 130 calculates the solid content of the detection sewage according to the first preset volume of the detection sewage, the weight of the detection cylinder, and the weight of the second preset volume of clean water, providing a calculation basis for the concrete mix ratio, so that the detection sewage can be used as a component material of concrete, thereby preventing the problem of solid waste garbage being discarded due to digestion of sewage in the prior art.

[0055] like Figure 2 As shown, the detection cylinder 110 is directly fixed at a designated position, such as the ground, and the detection cylinder 110 is in an inverted cone shape, that is, the diameter of the detection cylinder 110 gradually decreases from top to bottom. The sewage solid content detection device also includes:

[0056] A sewage inlet pipe 111, the sewage inlet pipe 111 is connected to the upper end of the detection cylinder 110, and a sewage inlet valve 111a is provided on the sewage inlet pipe 111;

[0057] A sewage discharge pipe 112, the sewage discharge pipe 112 is connected between the lower end of the detection cylinder 110 and the weighing unit 120, and a sewage discharge valve 112a and a drainage pump 112b are provided on the sewage discharge pipe 112;

[0058] A liquid level sensor 113, wherein the liquid level sensor 113 is disposed inside the detection cylinder 110;

[0059] The control unit 140 is electrically connected to the sewage inlet valve 111a, the sewage discharge valve 112a, the drainage pump 112b and the liquid level sensor 113 respectively.

[0060] The sewage inlet valve 111a and the sewage discharge valve 112a may be electromagnetic ball valves, which are opened and closed by the control unit 140. Of course, the sewage inlet valve 111a and the sewage discharge valve 112a may also be opened and closed manually.

[0061] When the control unit 140 controls the sewage inlet valve 111a to open, the sewage generated by flushing at various places can flow into the detection cylinder 110 through the sewage inlet pipe 111. The height of the liquid level sensor 113 inside the detection cylinder 110 and the shape of the detection cylinder 110 jointly determine the value of the first preset volume of the detection sewage, that is, when the liquid level sensor 113 detects that the sewage has reached its installation height, the control unit 140 controls the sewage inlet valve 111a to close so that the detection cylinder 110 carries the first preset volume of detection sewage. Then, the control unit 140 controls the sewage discharge valve 112a and the drainage pump 112b to open so that the first preset volume of detection sewage in the detection cylinder 110 flows into the weighing unit 120, and the weighing unit 120 weighs the first preset volume of detection sewage.

[0062] The weighing unit 120 may include a weighing device and a container disposed on the weighing device, wherein the first preset volume of the test sewage flows into the container and is weighed by the weighing device to obtain the weight of the test sewage. The weighing unit 120 is in communication connection with the detection unit 130, that is, the weighing unit 120 sends the weight of the test sewage to the detection unit 130, and the detection unit 130 calculates the solid content of the test sewage.

[0063] Of course, the weighing unit 120 can be a weight sensor, which is directly arranged on the detection cylinder 110 and is used to weigh the detection cylinder 110 carrying the detection sewage as a whole, and then the weight of the detection cylinder 110 is directly subtracted from the overall weight to obtain the weight of the detection sewage. At this time, the sewage unloading pipe 112 is used to drain the detection sewage to the concrete production workshop for concrete production.

[0064] like Figure 2 As shown, the sewage solid content detection equipment also includes:

[0065] Cleaning water tank 150;

[0066] The cleaning water outlet pipe 152 is connected between the cleaning water tank 150 and the upper end of the detection cylinder 110. The cleaning water outlet pipe 152 is provided with a cleaning water unloading valve 152a and a cleaning water pump 152b. The cleaning water unloading valve 152a and the cleaning water pump 152b are electrically connected to the control unit 140 respectively.

[0067] After the detection cylinder 110 completes one detection sewage transportation, the inside of the detection cylinder 110 is cleaned through the cleaning water tank 150 to carry out the next detection sewage transportation. During cleaning, the control unit 140 controls the sewage inlet valve 111a and the drainage water pump 112b to be closed, and the control unit 140 controls the cleaning water discharge valve 152a and the cleaning water pump 152b to be opened, so that the cleaning water in the cleaning water tank 150 is introduced into the inside of the detection cylinder 110 through the cleaning water outlet pipe 152 to clean the inside of the detection cylinder 110. The water in the detection cylinder 110 can be discharged through the sewage discharge pipe 112 and the additional pipes connected thereto, or used as detection sewage.

[0068] Similarly, the cleaning water discharge valve 152a and the cleaning water pump 152b can be manually controlled to open and close in addition to being electrically controlled by the control unit 140.

[0069] Preferably, a spraying device 154 is provided at the end of the cleaning water outlet pipe 152 . The spraying device 154 is located in the detection cylinder 110 and close to the upper end of the spraying device 154 to enhance the cleaning effect on the inside of the detection cylinder 110 .

[0070] like Figure 2 As shown, the sewage solid content detection equipment also includes:

[0071] A cleaning water inlet pipe 151, wherein the cleaning water inlet pipe 151 is connected to the cleaning water tank 150, and a cleaning water inlet valve 151a is provided on the cleaning water inlet pipe 151;

[0072] A cleaning water level gauge 153, wherein the cleaning water level gauge 153 is disposed inside the cleaning water tank 150;

[0073] The cleaning water inlet valve 151 a and the cleaning water level gauge 153 are electrically connected to the control unit 140 , respectively.

[0074] After the cleaning water level sensor 153 detects that the cleaning water in the cleaning water tank 150 is lower than the installation position of the cleaning water level sensor 153, the control unit 140 controls the cleaning water inlet valve 151a to open, so as to introduce cleaning water into the cleaning water tank 150, until the cleaning water reaches the installation position of the cleaning water level sensor 153, then the control unit 140 controls the cleaning water inlet valve 151a to close. The cleaning water level sensor 153 is a part of the liquid level switch, which is used to sense the water level in the cleaning water tank 150. Similarly, the cleaning water inlet valve 151a can also be manually controlled to open and close.

[0075] In summary, the volume of the detection cylinder 110 and the liquid level sensor 113 installed inside the detection cylinder 110 determine the first preset volume value that can carry the detection sewage. It can be seen that the detection cylinder 110 can define the volume of the detection sewage, and then the weighing unit 120 weighs the first preset volume of the detection sewage discharged by the detection cylinder 110 to obtain the weight of the detection sewage. Finally, the detection unit 130 calculates the solid content of the detection sewage according to the first preset volume of the detection sewage, the weight of the detection cylinder, and the weight of the second preset volume of clean water, providing a calculation basis for the concrete mix, so that the detection sewage can be used as a component material of concrete, preventing the problem of digestion of sewage in the prior art, which causes the difficulty of discarding solid waste. In addition, the sewage solid content detection equipment can be switched between manual and automatic use. In the automatic state, the solid content of the detection sewage can be measured, stored, and updated online in real time. It has a simple structure, convenient maintenance, accurate measurement, and full process automation control.

[0076] Second embodiment

[0077] like Figure 2 and Figure 3 As shown, the detection method of the sewage solid content detection device comprises the following steps:

[0078] S210, introducing a first preset volume of test sewage into the test cylinder 110;

[0079] S220, weighing the test sewage by the weighing unit 120 to obtain the weight of the test sewage;

[0080] S230, using the detection unit 130 to calculate the weight of the detection sewage, the weight of the detection cylinder recorded by the detection unit 130, and the weight of the clean water of the second preset volume to obtain the solid content of the detection sewage, and the first preset volume is equal to the second preset volume.

[0081] The detection method of the sewage solid content detection device is the detection method of the sewage solid content detection device of the first embodiment.

[0082] refer to Figure 2 Before step S210, the detection method further includes the following steps:

[0083] Introducing clean water into the detection cylinder 110;

[0084] When the liquid level sensor 113 detects that the clean water in the detection cylinder 110 reaches a preset liquid level, the introduction of clean water into the detection cylinder 110 is stopped, so that the detection cylinder 110 carries a second preset volume of clean water;

[0085] The clean water is weighed by the weighing unit 120 , and the weight of the clean water is recorded by the detection unit 130 .

[0086] It can be seen that the detection cylinder 110 and the weighing unit 120 are also used to obtain the weight of the second preset volume of clean water, wherein the second preset volume is equal to the first preset volume, and the clean water weight is recorded by the detection unit 130. Afterwards, each time the solid content of the sewage is calculated and tested using the sewage solid content detection device, the clean water weight recorded by the detection unit 130 can be directly retrieved.

[0087] Similarly, the detection cylinder 110 only needs to be weighed once, and then the weight of the detection cylinder recorded by the detection unit 130 can be directly retrieved to calculate the solid content of the detection sewage.

[0088] refer to Figure 2 The detection cylinder 110 is provided with a liquid level sensor 113 inside, and the step S210 includes the following steps:

[0089] When the liquid level sensor 113 detects that the test sewage reaches a preset liquid level in the test cylinder 110 , the introduction of the test sewage into the test cylinder 110 is stopped, so that the test cylinder 110 carries the test sewage of a first preset volume.

[0090] The volume of the detection cylinder 110 and the liquid level sensor 113 installed inside the detection cylinder 110 determine the first preset volume value that can carry the detection sewage. Specifically, when the control unit 140 controls the sewage inlet valve 111a to open, the sewage generated by flushing at various places can flow into the detection cylinder 110 through the sewage inlet pipe 111. When the liquid level sensor 113 detects that the sewage reaches its installation height, the control unit 140 controls the sewage inlet valve 111a to close, so that the detection cylinder 110 carries the first preset volume of detection sewage.

[0091] In step S220, the control unit 140 controls the sewage discharge valve 112a and the drainage pump 112b to open, so that the first preset volume of the detection sewage in the detection cylinder 110 flows into the weighing unit 120, and the weighing unit 120 weighs the first preset volume of the detection sewage.

[0092] In the step S230, the detection unit 130 may use the following formula to calculate the solid content of the detected sewage:

[0093] ;

[0094] Wherein, Y is the solid content of the detected sewage, X is the weight of the sewage in the first preset volume, and a is the weight of the clean water in the second preset volume, wherein the first preset volume and the second preset volume are equal.

[0095] refer to Figure 2 After step S230, the method further includes the following steps:

[0096] The interior of the detection cylinder 110 is cleaned by the cleaning water drawn out from the cleaning water tank 150 .

[0097] After the detection cylinder 110 completes one detection wastewater transportation, the cleaning water tank 150 is used to clean the inside of the detection cylinder 110 so as to carry out the next detection wastewater transportation and detection.

[0098] Third embodiment

[0099] like Figure 2 and Figure 4 As shown, the concrete mix method comprises the following steps:

[0100] S310, obtaining sewage as a concrete component material;

[0101] S320, introducing the sewage into the detection cylinder 110 to obtain a first preset volume of detection sewage;

[0102] S330, weighing the test sewage by the weighing unit 120 to obtain the weight of the test sewage;

[0103] S340, the detection unit 130 calculates the weight of the detection sewage, the weight of the detection cylinder recorded by the detection unit 130, and the weight of the clean water of the second preset volume to obtain the solid content of the detection sewage, and the first preset volume is equal to the second preset volume;

[0104] S350. Determine the mix ratio of each component material of concrete based on the solid content of the detected sewage, and prepare concrete using the mix ratio of the component materials of concrete.

[0105] In step S310, the sewage may be sewage generated by flushing in various occasions.

[0106] The steps S320 to S340 may refer to the second embodiment and are not described in detail here. Between the steps S340 and S350, the method further includes the following steps:

[0107] When the solid content of the detected sewage meets the preset conditions, the step S350 is performed, and if not, an alarm is given. The preset conditions refer to the solid content of the detected sewage being between 3% and 15%, wherein the interval value can be changed, and the alarm refers to the alarm being displayed through a display screen, light, sound, etc., and outputting an automatic adjustment signal, etc.

[0108] The solid content of the wastewater can be detected and recorded in real time and can be viewed as historical data.

[0109] The detected sewage is used as a component material of concrete to prevent the problem of difficult disposal of solid waste caused by digesting sewage in the prior art. The parameters involved in concrete include bulk density, total amount of gelling, admixture ratio, sand ratio, water-cement ratio, water-reducing agent dosage, sand water content, gravel water content, sewage solid content, and sand ratio regulator dosage. Specifically, step S350 includes the following steps:

[0110] S351, receiving the concrete mix parameters input by the user through the interface. The mix parameters may include:

[0111] Bulk weight 2520kg;

[0112] Total gelation volume 380kg;

[0113] The admixture ratio is 35%;

[0114] Sand rate 38%;

[0115] Water-cement ratio (0.35 unchanged), which reflects the proportional relationship between the amount of water in concrete and the amount of cementitious materials (including cement and admixtures, etc.);

[0116] The water-reducing agent dosage is 0.26 (solid content 20%). The water-reducing agent dosage refers to the amount of water-reducing agent used in concrete, usually expressed as a percentage of the total amount of cementitious materials (such as cement, fly ash, mineral powder, etc.); the solid content of the water-reducing agent dosage refers to the content of non-volatile substances in the water-reducing agent except water, usually expressed as a percentage;

[0117] The water content of sand is 8%;

[0118] The water content of the stone is 1.5%;

[0119] The solid content of sewage is 53%;

[0120] The dosage of sand ratio regulator is 0.5%.

[0121] S352. Calculate the actual sewage volume according to the mix ratio parameters of the concrete received through the interface.

[0122] Theoretical total water consumption = total amount of gelling × water-binder ratio = 380 × 0.35 = 133 kg;

[0123] Admixture dosage = total amount of gelling agent × water reducing agent dosage / solid content = 380 × 0.26 / 0.2 = 4.94 kg;

[0124] Water in admixture = admixture dosage × (1-solid content) = 4.94 × (1-20%) = 3.95 kg;

[0125] Sand (dry material) dosage = (bulk density - total amount of gelling - theoretical total water consumption - admixture dosage) × sand ratio = (2520-380-133-4.94) × 0.38 = 760.78 kg;

[0126] Water content in sand = amount of sand (dry material) × (1 + water content of sand) - amount of sand (dry material) = 760.78 × (1 + 8%) - 760.78 = 60.862624;

[0127] The amount of gravel (dry material) = (bulk density - total amount of gelling - theoretical total water consumption - amount of admixture) × (1-sand ratio) = (2520-380-133-4.94) × (1-0.38) = 1241.2772 kg;

[0128] Water content in stone = amount of stone (dry material) × (1 + water content of stone) - amount of stone (dry material) = 1241.2772 × (1 + 1.5%) - 1241.28 = 18.62;

[0129] Theoretical water consumption = theoretical total water consumption - water content in sand - water content in stone - water in admixture = 133-60.86-18.62-3.95 = 49.57kg;

[0130] At this time, the theoretical slurry dosage is = theoretical water consumption / (1-slurry solid content) = 49.57 / (1-slurry solid content) = 49.57 / (1-0.53) = 105.47;

[0131] Solids in slurry = theoretical slurry dosage × solid content of sewage = 105.47 × 0.53 = 55.90;

[0132] When the water-binder ratio remains unchanged, the solids in the slurry are deducted from the dry sand and dry stone;

[0133] Dry sand amount = sand (dry material) amount - solids in slurry × sand ratio = 760.78-55.9×0.38=739.54kg;

[0134] Dry stone quantity = stone (dry material) quantity × (1-sand ratio) = 1241.28-55.9 × 0.62 = 1206.62 kg;

[0135] Wet sand consumption = dry sand consumption × (1 + water content) = 739.54 × 1.08 = 798.7 kg;

[0136] Amount of wet stone = amount of dry stone × (1 + water content) = 1206.62 × 1.015 = 1224.72;

[0137] Actual sewage consumption = bulk density - total amount of cement - wet stone consumption - wet sand consumption - admixture consumption = 2520-380-1224.72-798.7-4.94 = 111.64;

[0138] At this time, the amount of each material in the mix ratio is:

[0139] Wet sand: 798.7; wet gravel: 1224.29; total amount of gelling agent: 380; admixture: 4.94; slurry: 111.64; bulk density = wet sand + wet gravel + total amount of gelling agent + admixture + slurry = 798.7 + 1224.72 + 380 + 4.94 + 111.64 = 2520kg.

[0140] S352. Calculate the solid content and water content in the sewage based on the actual amount of sewage used and the solid content of the detected sewage.

[0141] Solid content: actual sewage volume × solid content of detected sewage = 111.64 × 0.53 = 59.17 kg;

[0142] Water content in sewage: actual amount of sewage used - solid content = 111.64-59.17 = 52.47kg.

[0143] S353. Based on the solid content and water content in the sewage, calculate the water consumption for the mix ratio, the total amount of gelling and the actual water-to-cement ratio for stirring.

[0144] Total water consumption by mix weight = water content in sewage + water in admixture + water in sand and gravel = 52.47 + 3.95 + 798.7-798.7 / (1+water content) + 1224.72-1224.72 / (1+water content) = 52.47 + 3.95 + 59.16 + 18.1 = 133.68 kg;

[0145] Total amount of gelling = total amount of gelling in proportion + solid content = 380 + 59.17 = 439.17 kg;

[0146] Actual water-cement ratio in production mixing = total water consumption by mix weight / total amount of cementitious material = 133.68 / 439.17 = 0.30.

[0147] It can be seen that the mix ratio of the constituent materials includes the total water consumption, the total amount of gelling, and the actual water-cement ratio of mixing, and then concrete can be prepared according to the mix ratio of the constituent materials.
