Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a skid-mounted water flush toilet sewage treatment device. Background Art

[0002] The working areas of oil and gas field drilling teams and operation teams are mostly in the wild, with harsh environments and no municipal pipeline network. Tap water and domestic sewage are all delivered regularly by water tankers, which has high operating costs.

[0003] Traditional flush toilets are equipped with conventional integrated sewage treatment equipment, which requires a separate underground sewage collection pool. Oil and gas field crews frequently move around, and underground sewage pools are not easy to reuse, resulting in a waste of resources.

[0004] Drilling and operation teams frequently relocate, and their living and accommodation facilities are often in the form of camping buildings, which are directly transported during the relocation process. While power outages are common during relocation, the crews still need to use the restroom, and conventional flush toilets are not sufficient for this period.

[0005] Therefore, it is necessary to propose an improvement to overcome the defects of the prior art. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose to design a skid-mounted water-flushing toilet sewage treatment device to achieve on-site treatment and reuse of toilet flushing sewage. When the work team moves to another site, it can be directly hoisted to the site, reducing the investment in underground equipment.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] A skid-mounted water-flushing toilet sewage treatment device is integrated with the water-flushing toilet on a skid, realizing on-site sewage treatment and synchronous lifting and transportation; the sewage treatment device comprises a sewage collection tank, a septic tank, a regulating tank, a degradation reaction tank, a membrane assembly and a reuse water tank; the sewage collection tank is arranged below the squat toilet in the water-flushing toilet box, and the bottom of the squat toilet extends to the interior of the sewage treatment device, and the sewage in the water-flushing toilet directly enters the sewage treatment device; the sewage collection tank is connected to the septic tank, the septic tank is connected to the regulating tank, the regulating tank is connected to the degradation reaction tank, the degradation reaction tank is connected to the membrane assembly, and the membrane assembly is connected to the reuse water tank. The sewage enters the reuse water tank after being treated in the septic tank, the regulating tank, the degradation reaction tank and the membrane assembly in sequence, thereby realizing on-site reuse of toilet sewage.

[0009] Furthermore, the degradation reaction tank includes an anaerobic tank, an anoxic tank and an aerobic tank connected in sequence, and the sewage undergoes anaerobic, anoxic and aerobic reactions in sequence.

[0010] Furthermore, the sewage treatment device also includes an equipment room for installing power supply equipment, control equipment, maintenance equipment, dosing equipment, etc.

[0011] Furthermore, a lifting pump is provided inside the sewage collection tank for lifting the sewage into the septic tank.

[0012] Furthermore, a lifting pump is provided in the regulating tank for lifting the sewage into the degradation reaction tank.

[0013] Furthermore, the sewage treatment device and the flush toilet are arranged on the same bottom frame to form a skid.

[0014] Furthermore, a disinfection device is provided between the membrane assembly and the reuse water pool to sterilize and disinfect the water after membrane filtration.

[0015] Technical effects of this utility model:

[0016] Compared to existing technologies, this skid-mounted flush toilet sewage treatment device is integrated with the flush toilet, eliminating the need for a separate underground lift tank. Blackwater from flushing toilets flows directly into the sewage treatment device, where it undergoes on-site degradation. The treated effluent is then used directly for flushing toilets, while excess water can be used by the well crew for mud preparation and recharge. This device can accommodate the frequent relocations of well crews, allowing for simultaneous relocation with other campsites, allowing for direct transport and reuse once grounded and powered on.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0020] Example 1:

[0021] like Figure 1 As shown, the present embodiment involves a skid-mounted flush toilet sewage treatment device, which is arranged on the same bottom frame as the flush toilet 1 to form a skid block, realizing synchronous lifting and transportation, as well as on-site sewage treatment and reuse.

[0022] The sewage treatment device includes a sewage collection tank 2, a septic tank 3, a regulating tank 4, a degradation reaction tank, a membrane assembly 8, a reuse water tank 9 and an equipment room 10; the degradation reaction tank includes an anaerobic tank 5, an anoxic tank 6 and an aerobic tank 7.

[0023] The sewage collection tank 2 is located below the squat toilet in the flush toilet 1, and extends from the bottom of the squat toilet to the interior of the sewage treatment device. The sewage collection tank 2 is connected to the septic tank 3, and a lifting pump is installed inside the sewage collection tank 2 to lift the sewage into the septic tank 3. The septic tank 3 is connected to the regulating tank 4, which is connected to the anaerobic tank 5. A lifting pump is installed inside the regulating tank 4 to lift the sewage into the anaerobic tank 5. The anaerobic tank 5, the anoxic tank 6, the aerobic tank 7, the membrane assembly 8, and the reuse water tank 9 are connected in sequence. The sewage undergoes anaerobic, anoxic, and aerobic reactions in sequence, enters the membrane assembly 8 for mud and water separation, and the separated water enters the reuse water tank 9.

[0024] The equipment room 10 is used to install power supply equipment, control equipment, maintenance equipment, dosing equipment, etc.

[0025] In order to further disinfect the treated sewage, a disinfection device is provided between the membrane assembly 8 and the reuse water pool 9 to sterilize the water after membrane filtration, thereby further improving the quality of the reuse water.

[0026] Working Principle: The area where the squat toilet is located within the water-flushing toilet 1 is partially elevated, and a sewage treatment device is installed on one side. A sewage collection tank 2 is installed partially below the squat toilet, partially extending into the sewage treatment device. A lifting pump is installed in the sewage collection tank 2 that extends into the sewage treatment device to lift the sewage into the septic tank 3. After initial sedimentation and hydrolysis and acidification, the supernatant enters the regulating tank 4. A lifting pump is installed in the regulating tank 4, and the lifting pump is automatically started and stopped by the liquid level control to lift the sewage into the degradation reaction tank. Anaerobic, anoxic, and aerobic reactions are carried out in sequence to degrade BOD5 and simultaneously remove nitrogen and phosphorus. The treated water can be separated from mud and water. A membrane assembly 8 (ultrafiltration membrane) is used for mud and water separation. The effluent after membrane filtration is sterilized and disinfected by a disinfection device before entering the reuse water tank 9. The effluent after the above treatment meets the standards for flushing and can be directly reused for flushing. Excess effluent can be used by the well team to prepare mud and recharge.

[0027] The sewage treatment device and the flush toilet 1 use the same bottom frame to form a skid. The skid is provided with a lifting hole. When the work team moves, the sewage collection tank 2, septic tank 3, etc. can be partially drained to reduce the weight, and directly lifted onto the transfer vehicle and transferred synchronously with other living and production facilities.

[0028] The above-mentioned specific implementation methods are only specific cases of the present utility model. The patent protection scope of the present utility model includes but is not limited to the above-mentioned specific implementation methods. Any appropriate changes or modifications made to them by ordinary technicians in the relevant technical field that comply with the claims of the present utility model shall fall within the patent protection scope of the present utility model.
