Description

Technical Field

[0001] This utility model belongs to the field of water supply treatment technology, specifically relating to an integrated water supply treatment device. Background Technology

[0002] In most rural areas, self-supplied wells are used as drinking water sources, which are then consumed directly without treatment. However, with societal progress, users have increasingly higher demands for water quality. Furthermore, excessive groundwater extraction has led to problems such as land subsidence and reduced groundwater resources. Currently, many areas are replacing groundwater sources with surface water. Because the original self-supplied wells were scattered and difficult to operate and manage, after replacing groundwater with surface water, an integrated water treatment system needs to be installed to centrally supply water to each village.

[0003] Surface water sources are characterized by high turbidity, high levels of organic pollutants, and occasional high algae content during the rainy season. Treatment processes must address the influent issue to ensure effluent meets drinking water standards. Considering the limited land and technical management capabilities in rural areas, a small-footprint, easily managed treatment device is required. Conventional small-scale integrated treatment devices used in rural areas employ conventional coagulation, sedimentation, and filtration processes, using tubular static mixers for mixing. However, tubular static mixers suffer from significant head losses and are unsuitable for water plants with large water volume fluctuations. Grid flocculation tanks are used, but during summer algae blooms, these tanks are prone to algae growth and mesh clogging, leading to cumbersome operation and increased operating costs. Given the significant seasonal variations in surface water quality and the large fluctuations in water consumption in rural areas, there is an urgent need to develop a small-scale integrated treatment device for surface water sources that requires minimal space and produces high-quality effluent. Utility Model Content

[0004] Based on the above-mentioned problems, this utility model provides an integrated water treatment device that can effectively solve problems such as poor operation, poor water output, and high operating costs.

[0005] The technical solution adopted by this utility model is as follows: An integrated water treatment device includes a coagulation sedimentation tank, a filter tank, an ozone contact tank, an activated carbon adsorption tank, a comprehensive pump room, and a backwash fan room. The coagulation sedimentation tank, filter tank, activated carbon adsorption tank, ozone contact tank, comprehensive pump room, and backwash fan room are built together and share the same tank wall.

[0006] Furthermore, the coagulation sedimentation tank connected to the inlet pipe is an inclined tube sedimentation tank. The effluent channel of the coagulation sedimentation tank is embedded in the coagulation sedimentation tank. The width of the coagulation sedimentation tank is consistent with the total width of the filter, activated carbon adsorption tank and supporting integrated pipe gallery. The filter, activated carbon adsorption tank and integrated pipe gallery are located outside the effluent channel of the coagulation sedimentation tank and share the tank wall with the effluent channel of the coagulation sedimentation tank. The effluent channel of the coagulation sedimentation tank is connected to the inlet channel of the filter through holes.

[0007] Furthermore, the filter tank and the activated carbon adsorption tank have the same bottom plate elevation and width, and share the same central integrated pipe gallery.

[0008] Furthermore, the integrated pump house shares pool walls with the filter, activated carbon adsorption tank, and integrated pipe gallery. The filter effluent channel and the activated carbon adsorption tank effluent channel are vertically arranged side by side in the integrated pump house, with a filter effluent overflow gate in the middle. An effluent pipe connected to the clear water tank is installed on the activated carbon adsorption tank effluent channel. The integrated pump house is equipped with an intermediate lift pump connecting the filter effluent channel and the ozone contact tank, a filter backwash pump connecting the filter effluent channel and the filter, and an activated carbon adsorption tank backwash pump connecting the activated carbon adsorption tank effluent channel and the activated carbon adsorption tank.

[0009] Furthermore, the outlet pipe of the ozone contact tank is connected to the activated carbon adsorption tank.

[0010] Furthermore, the backwashing blower room is jointly constructed with the integrated pump room and the ozone contact tank, sharing the same tank wall; the backwashing blower room is equipped with a filter backwashing blower and an activated carbon adsorption tank backwashing blower; the filter backwashing blower is connected to the filter through a filter backwashing air pipe, and the activated carbon adsorption tank backwashing blower is connected to the activated carbon adsorption tank through an activated carbon adsorption tank backwashing air pipe. The bottom elevation of the filter backwashing air pipe is more than 50cm higher than the highest water level of the filter, and the bottom elevation of the activated carbon adsorption tank backwashing air pipe is more than 50cm higher than the highest water level of the activated carbon adsorption tank.

[0011] Furthermore, the filter backwash water pump is connected to the filter via a filter backwash water pipe, and the activated carbon adsorption tank backwash water pump is connected to the activated carbon adsorption tank via an activated carbon adsorption tank backwash water pipe.

[0012] Furthermore, the filter backwashing air pipe, the activated carbon adsorption tank backwashing air pipe, the filter backwashing water pipe, and the activated carbon adsorption tank backwashing water pipe are installed in the integrated pipe gallery.

[0013] Furthermore, the filter beds are arranged in four groups, and the filter media is uniformly sized quartz sand with a particle size range of 0.9-1.2 mm and a non-uniformity coefficient K. 60 ≤1.6; Four sets of activated carbon adsorption tanks are arranged, and the filter media is briquette crushed carbon with a particle size range of 1.2-1.3mm and a filter media layer height of 2m.

The water treatment structures, including coagulation sedimentation tanks, filter tanks, ozone contact tanks, activated carbon adsorption tanks, and supporting integrated pump rooms and backwash fan rooms, are constructed in a combined manner, sharing tank walls to reduce the footprint. Integrated equipment can be used, which reduces the difficulty of construction.

[0016] 2. The water treatment structure includes an ozone contact tank and an activated carbon adsorption tank for advanced treatment.

[0033] Specifically, the coagulation sedimentation tank mainly removes suspended solids and colloidal substances, reduces turbidity, removes some organic matter and phosphorus, and creates favorable conditions for subsequent treatment units. Considering the changes in water consumption by residential users and the rationality of the layout, the coagulation sedimentation tank is designed in four groups, with the total width of the coagulation sedimentation tank being close to the width of the filter and activated carbon adsorption tank. Mechanical mixing is used, with a mixing agitator and a mixing time of 60 seconds; mechanical flocculation is used, with a flocculation agitator and a flocculation time of 20 minutes.
