Description

Technical Field

[0001] The utility model relates to the field of water treatment equipment, in particular to a modular black water and grey water treatment equipment. Background Art

[0002] Black water generally comes from the wastewater of toilets and bathrooms, which contains human excreta (feces and urine). This kind of wastewater usually contains pathogenic bacteria harmful to the human body. Black water usually contains a relatively high amount of COD, N, P and pathogens. According to chemical analysis, the contents of N, P, K in black water are 1%, 0.5%, 0.37% respectively, the organic matter content is 2%, the main components of organic matter are cellulose, hemicellulose, protein and their decomposition products, and the water content is 70 - 80%. When this kind of wastewater is recycled and treated, it must be properly processed and decomposed to eliminate the bacteria in it, and then discharged reasonably. Therefore, the water in rural septic tanks cannot be directly discharged; grey water generally comes from clothes washing, kitchen water and bathing water. Compared with black water, it has a lower pollutant level and is easier to treat and process. If the chemical substances contained in it are less, it can even be directly used for irrigation. In the case of climate change leading to rising temperatures and shortages of available water resources, the reuse of water resources becomes particularly important. Therefore, the utilization value of grey water is constantly increasing.

[0003] When traditional water treatment equipment treats black water and grey water, it generally connects to the black water and grey water sources and mixes them together for treatment inside the equipment. It is impossible to resourcefully utilize the organic nutrients in black water, resulting in energy waste. Moreover, the concentration of grey water is not high originally, and after mixing with black water, the concentration and impurities increase. This not only reduces the treatment efficiency and utilization rate, but also increases the treatment difficulty and cost. Summary of the Utility Model

[0027] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model. Embodiment

[0028] Referring to Figures 1-5 As shown, a modular black water and grey water treatment device of the present utility model includes:

[0029] A box body 1 with an accommodation cavity provided inside. The two ends of the box body 1 are respectively provided with a first inlet 27, a second inlet 7 and an outlet. The first inlet 27 and the second inlet 7 are respectively communicated with a grey water source and a black water source;

[0030] A module assembly accommodated in the accommodation cavity, including: a black water anaerobic module for black water treatment, and a grey water anaerobic module, an optional module and a grey water sedimentation module for grey water treatment and connected in sequence. The black water anaerobic module is communicated with the first inlet 27 of the box body 1, the grey water anaerobic module is communicated with the second inlet 7 of the box body 1, and the grey water sedimentation module is communicated with the outlet of the box body 1;

[0031] A water storage cavity is formed by enclosing between the module assembly and the accommodation cavity. The black water anaerobic module is communicated with the water storage cavity, and a water pump 13 is arranged in the water storage cavity. The outlet of the water pump 13 passes through the box body 1 and extends outwards.

[0032] For the modular black water and grey water treatment device of the present utility model, the accommodation cavity in the box body 1 is used to accommodate and install each water treatment module. The first inlet 27 of the box body 1 is connected to a black water source, such as a toilet sewage source, through a black water inlet pipe 6. The second inlet 7 of the box body 1 is connected to a grey water source, such as a sewage source in a kitchen, bathroom, etc., through a grey water inlet pipe 20. Its outlet is used to discharge the treated up-to-standard water.

[0033] The black water anaerobic module in the module assembly is a tank structure. The black water undergoes biochemical reactions in the tank and then enters the water storage chamber of the equipment, where it continues to ferment and be harmlessly treated. After 60-90 days of fermentation and harmlessness, it can be used as an organic fertilizer resource. The black water anaerobic module is filled with anaerobic bacteria culture medium to promote anaerobic fermentation and decomposition of organic matter in the black water.

[0034] The grey water anaerobic module is also a tank structure with an internal environment suitable for the growth of anaerobic microorganisms and is used for the preliminary treatment of grey water.

[0035] The optional module can be selected as an anoxic module or an aerobic module according to actual needs. When the anoxic module is selected, it is suitable for situations where the water quality requirements are not high. An anoxic environment is created inside to promote the decomposition of pollutants by specific microorganisms; when the aerobic module is selected, an aeration device 21 is installed inside to provide sufficient oxygen for aerobic microorganisms by introducing air, further improving the treatment effect, and is suitable for scenes with high water quality requirements.

[0036] The grey water sedimentation module is a sedimentation tank structure, which is used to precipitate impurities in the treated grey water. The output port of the grey water sedimentation module is connected to the first output port 8 of the housing 1 to discharge the grey water irrigation water that meets the standards.

[0037] After the module assembly is installed in the accommodating cavity, the water storage cavity formed between the module assembly and the accommodating cavity is used to store intermediate water in the treatment process or temporarily store part of the fertilization water that meets the standards after the black water treatment.

[0038] The water pump 13 arranged in the water storage chamber is a centrifugal water pump 13, which is connected to an external power supply through electric wires and controlled by an external control system. The water pump 13 is connected to a water pump 13 pipe and an external gray water pipe. The box body 1 is provided with a second output port 15 adapted to the gray water pipe.

[0039] Black water enters the black water anaerobic module from the first input port 27, and undergoes anaerobically fermented under the action of anaerobic bacteria to decompose organic matter and reduce the concentration of pollutants. The treated black water enters the water storage chamber, and gray water enters the gray water anaerobic module from the second input port 7 for preliminary anaerobic treatment, and then passes through the optional module (anoxic or aerobic treatment selected according to demand) and the gray water sedimentation module in sequence to further remove pollutants and impurities. When the treated water needs to be reused, the water pump 13 is started to pump the water in the water storage chamber out of the box 1 and transport it to the reuse and fertilization site through the external pipe.

[0040] The black water anaerobic module, the grey water anaerobic module, the optional module and the grey water sedimentation module are arranged to form a square matrix. The housing 1 is also provided with a first opening 2 and a second opening 3. Two sewage treatment modules are respectively arranged below the first opening 2 and the second opening 3. The first opening 2 and the second opening 3 are respectively used for placing and operating the water treatment modules below.

[0041] It also includes a septic tank 5, which is respectively provided with an input port and an output port to communicate with the black water source and the black water anaerobic module 9. The input port 4 of the septic tank 5 is connected to black water sources such as the toilet sewage source through pipelines, stores and ferments in a large capacity in the septic tank 5, and then enters the black water anaerobic module 9 through the black water input pipe 6.

[0042] The upper part of the black water anaerobic module 9 is respectively provided with an output port and an input port. The input port of the black water anaerobic module 9 is connected to the output port of the septic tank 5, and the output port of the black water anaerobic module 9 is connected to the water storage cavity. Black water enters from the upper part of the black water anaerobic module 9 and is discharged to the water storage cavity from the upper part after being treated, so that black water ferments and reacts at the bottom of the black water anaerobic module 9 and is discharged from the upper part.

[0043] The upper part of the grey water anaerobic module 10 is respectively provided with an input port and an output port. The input port of the grey water anaerobic module 10 is connected to the second input port 7 of the box body 1. Grey water sources such as those from the kitchen and bathroom enter through the external connecting pipe into the second input port 7 and carry out fermentation and biochemical reactions in the grey water anaerobic module 10. The output port of the grey water anaerobic module 10 is connected to an optional module. After the grey water is preliminarily treated in the grey water anaerobic module 10, it flows out from the upper output port to the optional module. The optional module is an aerobic module or an anoxic module. When the optional module is an aerobic module, an aeration device 21 is arranged therein, and an optional pipe 17 is also arranged above the optional module for inputting treatment agents.

[0044] A grey water anaerobic pipe 23 is arranged in the grey water anaerobic module 10. One end of the grey water anaerobic pipe 23 is arranged below the inner cavity of the grey water anaerobic module 10, and the other end extends upward to the grey water precipitation module 11. The input port of the grey water precipitation module 11 is located in its upper part. After the grey water enters the grey water anaerobic module 10, it carries out biochemical reactions in the grey water anaerobic module 10 and enters the pipe through the lower end of the grey water anaerobic pipe 23 for the next module, and the organic matter therein is decomposed and transformed by anaerobic microorganisms and / or chemical reactants.

[0045] The greywater sedimentation module 11 and the optional module 12 are connected through a U-shaped pipe 22. Two groups of parallel pipes of the U-shaped pipe 22 respectively extend to the lower parts of the inner cavities of the greywater sedimentation module 11 and the optional module 12. The bent part of the U-shaped pipe 22 passes through the upper parts of the greywater sedimentation module 11 and the optional module 12. An aeration device 21 is also arranged below the greywater sedimentation module 11. The first end of the U-shaped pipe 22 is at the lower part of the greywater sedimentation module 11 and close to the aeration device 21, so that the water to be treated needs to pass through the aeration area to enter the optional module 12, improving the aeration efficiency. The aeration device 21 is externally connected to a solar panel for driving, so as to operate self-sustainedly. The second end of the U-shaped pipe 22 is at the lower part of the optional module 12, thus avoiding polluting the upper clear water. In the optional module 12, the solid particles in the water gradually settle to the bottom under the action of gravity, and the relatively clear water in the upper layer is discharged through its outlet or undergoes subsequent treatment.

[0046] Referring to Figures 3-4 As shown, the outlet of the optional module 12 is also connected to a disinfection module. The outlet of the optional module 12 is connected to the inlet of the disinfection module through a disinfection pipe 18. The outlet of the disinfection module is externally connected to an irrigation pipe to disinfect the treated water to kill the remaining pathogens and microorganisms and ensure water quality safety. The disinfection device is provided with, for example, an ultraviolet disinfection device or a chemical dosing disinfection device 19 (such as putting disinfectants like sodium hypochlorite).

[0047] The blackwater overflow outlet 25 enables the blackwater to undergo biochemical reactions in the blackwater anaerobic module 9 tank and then enter the interior of the equipment barrel for continuous fermentation and harmless treatment. After 60 - 90 days of fermentation and harmless treatment, it can already be used as organic fertilizer for resource utilization. If farmers have needs, they can directly draw water from the barrel for fertilization. The upper part of the greywater anaerobic module 10 is also provided with a greywater overflow inlet 24, and the greywater overflow inlet 24 is connected to the water storage cavity. If not utilized, it enters the greywater anaerobic tank through the upper greywater overflow inlet 24.

[0048] Referring to Figure 5 As shown, a slag discharge port 16 is arranged at the lower part of the greywater sedimentation module. The discharged waste residue can be collected for subsequent treatment and recycling. By regularly discharging the slag, the good operating state of the greywater sedimentation module can be maintained, and the treatment efficiency and stability of the entire blackwater and greywater treatment equipment can be improved.

[0049] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
