Description
Technical field
This utility model relates to a kind of defecator, is specifically related to a kind of active sand defecator.
Background technology
Existing active sand filter, mainly includes air lift, sand-washing device, water-locator, water collector, sand hopper and control system.Water pollutes increasingly severe now, and discharge standard is more and more higher, and active sand filter is cannot meet sewage disposal requirement instantly, it is impossible to remove NH in water4-N。
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiency of the prior art, it is provided that a kind of structure arranges rationally, effectively removes NH4The novel active sand filter of-N.
Technical scheme: in order to solve above-mentioned technical problem, a kind of novel active sand filter described in the utility model, it includes filter body, it is provided with stripping tube in the middle part of described filter body, it is provided with pipeline on tube wall bottom described stripping tube, it is connected with air switch board, it is provided with water-locator in described filter body, described water-locator is connected with water inlet pipe, it is provided with sand hopper below described water-locator, it is provided with washed-out sand room at described stripping tube top, ripple sand developing tube it is provided with bottom washed-out sand room, described washed-out sand room is connected with discharge pipeline, by described washed-out sand room, overflow groove is set, annular gas distribution pipe it is provided with between described water-locator and sand hopper, it is connected with air inlet pipe.
The bottom of described filter body is taper.
At least provided with two ripple sand developing tubes bottom described washed-out sand room.
The horizontal length of described annular gas distribution pipe is identical with the horizontal length of water-locator port, accounts for the 4/5-9/10 of filter body horizontal length.
Beneficial effect: compared with prior art, its remarkable advantage is this utility model: this utility model structure arranges rationally, arranges annular gas distribution pipe between water-locator and sand hopper, forms microbial film at sea sand layer, effectively removes the NH in sewage4-N, removing ammonia nitrogen ability and reach 75%, use the annular gas distribution pipe accounting for filter body horizontal length 4/5-9/10, gas distribution efficiency is high, using effect is good, can quickly form microbial film, use ripple sand developing tube, washed-out sand is effective, this plant running is steady, use reliable, actual operation requirements can be met long lasting for work.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of novel active sand filter described in the utility model, it includes filter body 1, it is provided with stripping tube 2 in the middle part of described filter body 1, it is provided with pipeline 3 on tube wall bottom described stripping tube 2, it is connected with air switch board 4, it is provided with water-locator 5 in described filter body 1, described water-locator 5 is connected with water inlet pipe 6, it is provided with sand hopper 7 below described water-locator 5, it is provided with washed-out sand room 8 at described stripping tube 2 top, ripple sand developing tube 9 it is provided with bottom washed-out sand room 8, described washed-out sand room 8 is connected with discharge pipeline 10, on side, described washed-out sand room 8, overflow groove 11 is set, annular gas distribution pipe 12 it is provided with between described water-locator 5 and sand hopper 7, it is connected with air inlet pipe 13；The bottom of described filter body 1 is taper；At least provided with two ripple sand developing tubes 9 bottom described washed-out sand room 8；The horizontal length of described annular gas distribution pipe 12 is identical with the horizontal length of water-locator 5 port, accounts for the 4/5-9/10 of filter body 1 horizontal length.This utility model structure arranges rationally, arranges annular gas distribution pipe, form microbial film at sea sand layer between water-locator and sand hopper, effectively removes the NH in sewage4-N, removing ammonia nitrogen ability and reach 75%, use the annular gas distribution pipe accounting for filter body horizontal length 4/5-9/10, gas distribution efficiency is high, using effect is good, can quickly form microbial film, use ripple sand developing tube, washed-out sand is effective, this plant running is steady, use reliable, actual operation requirements can be met long lasting for work.
This utility model provides a kind of thinking and method; the method and the approach that implement this technical scheme are a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications; these improvements and modifications also should be regarded as protection domain of the present utility model, and each ingredient the clearest and the most definite in the present embodiment all can use prior art to be realized.
