Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to an integrated water purification device. Background Art

[0002] With the progress of society and the development of science and technology, the purification process of urban drinking water has also been continuously developed and improved. In the early 20th century, due to unclean drinking water, severe waterborne bacterial infectious diseases (cholera, dysentery, typhoid fever, etc.) often broke out in cities. In order to ensure the microbial safety of drinking water, the first generation of urban drinking water purification process (coagulation-sedimentation-filtration-chlorine disinfection) was developed. In the 1970s, a variety of trace organic pollutants and chlorination disinfection by-products that were harmful to the human body were found in urban drinking water. The first generation of processes could not effectively remove and control them. Against this background, the second generation of urban drinking water purification process was developed (ozone-activated carbon treatment was added after the first generation of processes). At the end of the 20th century, pathogenic protozoa-Giardia lamblia and Cryptosporidium (i.e., "two worms"), large-scale reproduction of algae and the resulting algal toxins and odors, biological stability of water and other major microbial safety issues were found in urban drinking water, and the treatment of high organic matter and high ammonia nitrogen water quality water, thus developing the third generation of urban drinking water purification process (combined process with ultrafiltration as the core technology).

[0003] At present, most water plants use different water purification processes due to different water sources. Generally, they use the first generation purification process or the first, second and third generation coupled purification process, which has the disadvantages of long process flow, large land occupation, high investment and operation cost, and complex operation and maintenance.

[0029] Combine the following Figure 1 The technical solution provided by the utility model is described in more detail.

[0030] The utility model provides an integrated water purification device, comprising:

[0031] A mechanical mixing tank 1, wherein the water inlet end of the mechanical mixing tank 1 is connected to the water source inlet, and a mechanical agitator 1-1 is arranged in the mechanical mixing tank 1;

[0032] A grid flocculation tank 2 is arranged at the water outlet of the mechanical mixing tank 1, and a plurality of grid plates 2-1 are arranged in the grid flocculation tank 2;

[0033] An inclined tube sedimentation tank 3, wherein a guide wall 3-1 and a plurality of inclined tubes 3-2 arranged obliquely are arranged in the inclined tube sedimentation tank 3, wherein the guide wall 3-1 is arranged at one side of the water outlet end of the grid flocculation tank 2 to guide the water source discharged from the grid flocculation tank 2 to below the inclined tube 3-2, and an online turbidity detector 3-4 is arranged at the water outlet end of the inclined tube sedimentation tank 3 to monitor the turbidity of the water outlet from the inclined tube sedimentation tank 3;

[0034] An ultrafiltration membrane pool 4, wherein the ultrafiltration membrane pool 4 is arranged at the outlet end of the inclined tube sedimentation tank 3;

[0035] The water levels of the mechanical mixing tank 1, the grid flocculation tank 2, the inclined tube sedimentation tank 3 and the ultrafiltration membrane tank 4 are sequentially reduced.

[0036] The integrated water purification equipment provided by the utility model comprises a mechanical mixing tank 1, a grid flocculation tank 2, an inclined tube sedimentation tank 3 and an ultrafiltration membrane tank 4. The water levels of the mechanical mixing tank 1, the grid flocculation tank 2, the inclined tube sedimentation tank 3 and the ultrafiltration membrane tank 4 are successively lowered, and the siphon pressure generated by the liquid surface pressure difference is used as the power of membrane separation. The power consumption and manual maintenance cost of the whole water purification process are greatly reduced, saving energy consumption and operating costs; at the same time, the mechanical mixing tank 1 can stir the water source and the reagent in the mechanical mixing tank 1 through the mechanical agitator 1-1 to fully mix them, a grid plate 2-1 is arranged in the grid flocculation tank 2, and the grid plate 2-1 flows up and down in an alternating manner to carry out flocculation reaction, and the inclined tube The sedimentation tank 3 can separate the mud and water in the water source, and then filter it in the ultrafiltration membrane tank 4. The ultrafiltration membrane tank 4 can remove almost all pathogenic microorganisms, so in principle there is no need to sterilize the filtered water; in addition, through the flocculation + sedimentation + immersion ultrafiltration process, various pollutants in the water can be effectively removed, and the ultrafiltration process is a continuous non-phase change filtration. When the water quality indicators such as the turbidity of the inlet water and microorganisms fluctuate greatly due to factors such as seasons and climate, the ultrafiltration system can still operate stably and the effluent meets the standards. In addition, the integrated water purification equipment has a short process flow, a small footprint, simple operation and maintenance, and is superior to other processes in terms of electricity consumption, drug consumption, labor, and overhaul maintenance. Therefore, it has lower infrastructure costs and operating costs.

[0037] As a further improvement of the present invention, a water inlet bypass pipe A is provided between the water source inlet and the ultrafiltration membrane pool 4 .

[0038] In this further improvement, by setting an inlet bypass pipe A between the water source inlet and the ultrafiltration membrane pool 4, when the online turbidity detector 3-4 set at the front end of the inlet bypass pipe A detects that the inlet turbidity is less than 2.0NTU, the water source directly passes through the inlet bypass pipe A into the ultrafiltration membrane pool 4 for filtration and disinfection; there is no need to go through the mixing, flocculation and sedimentation processes of the mechanical mixing tank 1, the grid flocculation tank 2 and the inclined tube sedimentation tank 3, which greatly reduces the invalid process flow, saves the amount of coagulant, and ensures that the equipment does not operate ineffectively.

[0039] As a further improvement of the present invention, a sedimentation water outlet pipe B is also provided at the outlet end of the inclined tube sedimentation tank 3 .

[0040] In this further improvement, by setting a sedimentation effluent bypass pipe B at the outlet end of the inclined tube sedimentation tank 3, when the online turbidity detector 3-4 set at the outlet end of the inclined tube sedimentation tank 3 detects that the effluent turbidity is less than a certain value (for example, 0.5NTU), the effluent from the inclined tube sedimentation tank 3 can enter the ultrafiltration membrane pool 4 and the clear water pool 5 respectively in a certain ratio (1:1~2:1), thereby reducing the operating load of the ultrafiltration membrane and extending the service life of the ultrafiltration membrane.

[0041] It should be noted that although the ultrafiltration membrane pool 4 can remove almost all pathogenic microorganisms, according to the current national standards, a small amount of disinfectant needs to be added to the water in the clean water pool 5 to prevent the water from being secondary polluted during the distribution process. Since the amount of disinfectant used is greatly reduced, the generation of disinfection by-products is also significantly reduced, thereby improving the biological and chemical safety of water.

[0042] Specifically, the inclination angle of the inclined tube 3 - 2 is 60 degrees; and / or the diameter of the inclined tube 3 - 2 is 25 mm to 40 mm; and / or the length of the inclined tube 3 - 2 is 1 m.

[0044] In this further improvement, the grid flocculation tank 2 is composed of 12 small flocculation tanks connected in sequence, and two adjacent small flocculation tanks are connected by a drain outlet set at the top or bottom. By setting a drain outlet between two adjacent small flocculation tanks, and the drain outlet is set at the top or bottom, it can prevent the water in the adjacent small flocculation tanks from flowing directly from the top, resulting in failure of sufficient flocculation of the water.

[0045] It can be understood that the first small flocculation tank and the second small flocculation tank are connected through the drain outlet at the bottom, and the second small flocculation tank and the third small flocculation tank are connected through the drain outlet at the top, and the bottom and top drain outlets are arranged in sequence, which enables the water in the grid flocculation tank 2 to fully undergo flocculation reaction and to flow in an interlaced manner under the action of the grid plate, thereby improving the flocculation effect.

[0046] As a further improvement of the present invention, four layers of grid plates 2-1 are arranged in the first two small flocculation tanks of the grid flocculation tank 2; and / or, three layers of grid plates 2-1 are arranged in the third small flocculation tank; and / or, two layers of grid plates 2-1 are arranged in the fourth to eighth small flocculation tanks; and / or, one layer of grid plates 2-1 is arranged in the ninth to eleventh small flocculation tanks.

[0047] In this further improvement, by arranging different numbers of grid plates 2 - 1 in each small flocculation tank, it is possible to ensure staggered flow under the action of the grid plates 2 - 1 to carry out flocculation reaction.

[0048] As a further improvement of the utility model, an ultrafiltration membrane assembly 4-1 and a siphon water production pipe 4-2 are arranged in the ultrafiltration membrane pool 4, the first end of the siphon water production pipe 4-2 is connected to the ultrafiltration membrane assembly 4-1, and the second end of the siphon water production pipe 4-2 is connected to the clean water tank 5.

[0049] In this further improvement, the ultrafiltration membrane assembly 4-1 is capable of filtering the water source and discharging the water to the clean water tank 5 through the siphon water production pipe 4-2 under the siphon pressure generated by the liquid level difference.

[0050] As a further improvement of the present invention, the ultrafiltration membrane assembly 4-1 adopts a columnar or curtain structure, and the membrane flux of the ultrafiltration membrane assembly 4-1 is 18 to 20 L / (m 2 h).

[0051] As a further improvement of the present invention, a mud discharge pipe 3-3 is provided at the bottom of the inclined tube sedimentation tank 3, and a mud discharge pool is provided at the discharge outlet of the mud discharge pipe 3-3.
