Abstract
The utility model relates to the technical field of water treatment, and particularly relates to a pretreated backwashing water recycling system. The pretreated backwashing water recycling system comprises a backwashing water storage tank, a booster pump, a filter and an ultrafiltration membrane device, wherein the backwashing water storage tank is used for recycling and storing pretreated backwashing water; a water inlet of the booster pump is communicated with the backwashing water storage tank; the booster pump is used for boosting pressure of the backwashing water in the backwashing water storage tank; a water inlet of the filter is communicated with a water outlet of the booster pump; the filter is used for filtering the backwashing water after pressure boosting; a water inlet of the ultrafiltration membrane device is communicated with a water outlet of the filter; the ultrafiltration membrane device is used for purifying the backwashing water filtered by the filter. According to the system provided by the utility model, the backwashing water pretreated by adopting the water treatment system is treated again by the filter and the ultrafiltration membrane device, and the treated product water can be re-used as production water, domestic water, water for dedusting, cooling and landscape, and the like, so that water resources are saved and the production cost of an enterprise is reduced.
Description
Technical field
The utility model relates to water-treatment technology field, relates in particular to a kind of pre-treatment backwash water recovery system.
Background technology
The pretreated backwash water of tradition water treatment system all enters the water exhaust system of factory, and what have directly enters Sewage treatment systems, and what have directly enters municipal sewage system.Each backwash water yield of large-scale water treatment system is very large, is generally 2-4 times of normal operation.No matter choose which kind of discharging modes, this backwash water yield is directly drained, do not recycle, and for the water resources being becoming tight day, be all a kind of waste.
Utility model content
In order to solve the problems of the prior art, the utility model provides a kind of pre-treatment backwash water recovery system, the pretreated backwash water of water treatment system can be reused after treatment, thus saving water resource.
In order to achieve the above object, the technical solution adopted in the utility model is:
Pre-treatment backwash water recovery system, comprising:
Backwash water tank, stores pretreated backwash water for reclaiming;
Topping-up pump, the water inlet of described topping-up pump is connected with described backwash water tank, for the backwash water of described backwash water tank is carried out to supercharging;
Strainer, the water inlet of described strainer is connected with the water outlet of described topping-up pump, for filtering the backwash water after supercharging;
Ultra-filtration membrane device, the water inlet of described ultra-filtration membrane device is connected with the water outlet of described strainer, for purifying the backwash water after described strainer filters.
Further, described recovery system also comprises product water tank, and described product water tank is connected with the product water water outlet of described ultrafiltration wave apparatus.
Further, described strainer is back flushing laminated filter.
Compared with prior art, the technique effect that the technical solution adopted in the utility model produces is:
The utility model is by being used strainer and ultra-filtration membrane device to process the pretreated backwash water of water treatment system again, make the product water after processing can again be used as water of productive use, domestic water, dedusting, cooling and landscape water etc., save water resources, also reduced the production cost of enterprise.
Accompanying drawing explanation
The structural representation of the pre-treatment backwash water recovery system that Fig. 1 provides for the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are described in detail.
As shown in Figure 1, the utility model embodiment provides a kind of pre-treatment backwash water recovery system, comprises backwash water tank 1, topping-up pump 2, strainer 3, ultra-filtration membrane device 4 and product water tank 5.Wherein, backwash water tank 1, stores pretreated backwash water for reclaiming; The water inlet of topping-up pump 2 is connected with backwash water tank 1, for the backwash water of backwash water tank 1 is carried out to supercharging; The water inlet of strainer 3 is connected with the water outlet of topping-up pump 2, for filtering the backwash water after supercharging; The water inlet of ultra-filtration membrane device 4 is connected with the water outlet of strainer 3, the backwash water after filtering for polishing filter 3, and the water outlet of ultra-filtration membrane device 4 is divided into dense water water outlet 41 and product water water outlet 42; Product water tank 5 is connected with the product water water outlet 42 of ultrafiltration wave apparatus 4.
Further, strainer in the utility model embodiment 4 is back flushing laminated filter, has served as after using for some time and can carry out back flushing, cleaning strainer.
The step that the pre-treatment backwash water recovery system of using the utility model embodiment to provide recycles pre-treatment backwash water is as follows:
Step 1: when pre-treatment backwash, the water just starting in first 5 minutes of backwash is directly entered to water exhaust system, the backwash water that backwash was carried out after 5 minutes is recovered in backwash water tank;
Step 2: utilize successively topping-up pump, back flushing laminated filter and ultra-filtration membrane device to process the backwash water in backwash water tank;
Step 3: directly enter water exhaust system from the dense water water outlet of ultra-filtration membrane device dense water out, product water water outlet product water out can be used as water of productive use, domestic water, dedusting, cooling and landscape water etc. again.
The utility model reclaims storage by backwash water tank by the pretreated backwash water of water treatment system, then by back flushing laminated filter and ultra-filtration membrane device, again backwash water is processed, water after processing is reused, thereby saved water resources, Ye Shi enterprise has saved cost.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
