Background
Water plants, as one of the capital constructions, play a very critical role in urban operation. However, with the increasing population and city scale, the water plants planned and constructed in the early days can not meet the existing water demand. Taking a certain city in the south as an example, the urban water-supply system has a first-stage production capacity of 30 ten thousand tons/day, the maximum peak daily overload is 20%, the water-supply capacity of 36 ten thousand tons/day is achieved (the index is close to the overload capacity limit of a water plant), and the annual external 5% increment is met, namely the quantity of about 1-2 ten thousand tons/day, namely 2018, and the water plant is expected to have a capacity of 38 ten thousand tons/day; in 2019, the capacity of 40 ten thousand tons/day can be realized; in 2020, the energy production capacity of 42 ten thousand tons/day can be realized. In order to meet the demand of water supply and water production, how to expand the capacity of the water plant becomes a pressing problem to be solved urgently.
aiming at the problem, the conventional method is to perform second-stage engineering extension, and assuming that the second-stage engineering is counted by 20 ten thousand tons/day, the expected construction time is 2 years, and the investment capital is about 2 million yuan (only considering building a sedimentation tank and a filter tank, and only adding equipment to the rest); the construction period of the extension is long, and the investment is huge, so that the development requirement of the city can not be met in a short time; meanwhile, when a conventional water plant carries out deep water treatment, with reference to fig. 1, a reaction sedimentation tank 1a → a sand filter tank 2a → an activated carbon filter tank 3a → a clean water tank 4a, and a reaction sedimentation tank 1a → an activated carbon filter tank 3a → a sand filter tank 2a → a clean water tank 4a are generally adopted, a small part of the series connection form is provided with an override pipe 5a, and a certain stage of working section is directly short-circuited by means of a bypass switch 51a on the override pipe 5a to realize capacity adjustment, but no parallel pipeline is designed or actually reserved for the activated carbon filter tank and the sand filter tank until now.
Disclosure of Invention
In view of the above, the present application provides a system for increasing the energy expansion of a water plant, which can achieve the purpose of increasing the capacity of the water plant by using the existing facilities without an expansion manner.
specifically, the method is realized through the following scheme:
A transformation system for expanding energy increment of a water plant comprises a sedimentation tank, a filter tank, a sludge treatment tank, a dosing facility and a clean water tank, wherein the filter tank is provided with a second-stage filter tank which is an active carbon filter tank and a uniform grain filter material filter tank in sequence, the sedimentation tank is connected with two water conveying branch pipes, the first water conveying branch pipe is connected with the dosing facility, water and a medicament to be treated are conveyed to the active carbon filter tank, and the second water conveying branch pipe is conveyed to the uniform grain filter material filter tank; the tail end of the activated carbon filter tank is provided with a mud water treatment tank, the mud water treatment tank is connected with a water outlet pipe and two sub-transmission pipes, the water outlet pipe is connected to a clean water tank, and the first sub-transmission pipe and the second sub-transmission pipe are respectively connected to the uniform particle filter material filter tank; bypass pipes are distributed between the first branch conveying pipe and the second branch conveying pipe, and between the second branch conveying pipe and the second water conveying branch pipe, and switches are respectively arranged on the bypass pipes and the water outlet pipes; the filter chamber is provided with a water outlet branch pipe which is connected to a water outlet pipe. The sludge treatment tank is preferably a post-ozone contact tank.
The filter tank is used as a core unit for the operation of a water plant, the designed filtering speed and the operating filtering speed of the filter tank have upper limit values, but the front-end sedimentation tank is designed according to the worst water quality, and the filter tank has larger load margin at ordinary times, and can ensure normal operation if the margin is configured on a bypass and generally exceeds the rated load by 50 percent. The scheme makes full use of the existing facilities for transformation, the sedimentation tank and a parallel tank (an activated carbon filter tank and a uniform grain filter material filter tank) are formed and connected in parallel by means of a water delivery branch pipe I and a water delivery branch pipe II, compared with the serial connection mode of a conventional water plant, the sedimentation tank can be adjusted to be connected in series with the activated carbon filter tank and the uniform grain filter material filter tank according to the real-time environment, the sedimentation tank can also be adjusted to be connected in parallel with the activated carbon filter tank and the uniform grain filter material filter tank after the sedimentation tank is connected in parallel, the activated carbon filter tank and the uniform grain filter material filter tank can also be connected in parallel by means of the on-off of a switch after the sedimentation tank.

More select, for avoiding the not enough problem of distribution well ability, can adopt three kinds of schemes: (1) the elevation of the distribution well relative to the activated carbon filter tank realizes the heightening of the distribution well, and the water level is improved to offset the head loss; (2) and the second water distribution well adopts a pressure type water distribution well, and the capacity complement is realized by means of the pressure principle of the water distribution well.
The filter material in the filter chamber of the uniform grain filter material adopts quartz sand or carbon sand. According to specific needs, filter grids of different scales are adopted to realize the change of the scales of different filters. If all the filter grids play a role, the capacity of the sedimentation tank can be doubled, and when half of the filter grids play a role, the capacity can be increased by 1/2.
the first water delivery branch pipe and the second water delivery branch pipe are made of PE pipes, and pipes are arranged on one side of the parallel tanks (the activated carbon filter tank and the uniform particle filter material filter tank). In the whole system, the shortage of pipeline positions is mainly reflected in two pipelines from the sedimentation tank to the filter tank, and the open pipes on the road surface are primarily considered; after the pipe is exposed, the influence on the traffic road is considered, the light PE pipeline is used, and a flange connection mode is adopted in a road section, so that the temporary disassembly and transportation are convenient; the pipe is arranged on one side, so that the road can pass at least on one side.
And a backwashing water pump is arranged in the uniform particle filter material filter tank, and preferably, a backwashing pipe is arranged at the position of the backwashing water pump facing the filter grids. Because the original equipment and pipeline of the back washing pump room are considered according to the carbon filter, after the equipment and the pipeline are changed into the uniform grain filter material filter tank with the sand filter tank structure, the strength requirement of back washing is increased, the pump lift and the matched motor power of the selected pump can be very large under the condition of not changing the pipeline, and if the equipment and the pipeline are taken as a temporary emergency project, the mode is convenient and fast under the premise of enough power capacity. The back washing strength can be effectively improved by increasing the caliber of the back washing pipe. Compared with the conventional activated carbon filter, the activated carbon filter is provided with a back washing system (a back washing pump, a back washing pipe and the like), a valve system and an automatic control system which are all universal, and quartz sand can be moved out to be used as a filter material for standby or used during expansion, so that waste is avoided. When the advanced water treatment is needed, the rear ozone contact tank is arranged at the tail end of the activated carbon filter tank, preferably, a storage tank is arranged in a matched manner in the sludge treatment tank, the storage tank is positioned at two sides of the tail end of the activated carbon filter tank, and an ozone generator is also arranged in the storage tank and matched with related facility equipment, so that the problem of time waste does not exist during the sand replacement by carbon.
The conventional extension accords with the public thinking, the project integrity is good, and the project is preferred certainly, but factors of large investment and long time exist, in terms of capital cost, 2 hundred million investments can be calculated by 6 percent of interest, the one-year capital cost can complete the reconstruction system provided by the application, in the reconstruction system provided by the application, except for the arrangement of a storage pool, relating to civil engineering, the rest is the purchase and installation of materials and equipment, almost no repeated investment and waste exist, the invested capital is about 1500 ten thousand yuan, which is 1/10 of the extension capital, and the economic benefit is obvious; in addition, from the aspect of time, factors such as engineering difficulty, manpower and material resource occupation and the like are considered, the implementation period is expected to be 6-8 months, and the method has obvious time advantage.
