The utility model discloses a circulating water treatment device for a public toilet with a septic tank. The circulating water treatment device comprises a feces tank and a septic tank, wherein the feces tank is connected with the septic tank; the circulating water treatment device also comprises a normal-temperature anaerobic biological filter, an up-flow biological aerated filter, a filtering and sterilizing segment and a water storage tank; the septic tank is connected with the normal-temperature anaerobic biological filter; the normal-temperature anaerobic biological filter is connected with the up-flow biological aerated filter; the up-flow biological aerated filter is connected with the filtering and sterilizing segment; the filtering and sterilizing segment is connected with the water storage tank; backwash effluent of the water storage tank is respectively connected to the feces tank, the normal-temperature anaerobic biological filter and the up-flow biological aerated filter; backwash effluents of the normal-temperature anaerobic biological filter and the up-flow biological aerated filter are connected to the septic tank. According to the utility model, the septic tank is used as a settling tank, the effluent sequentially passes through the normal-temperature anaerobic biological filter, the up-flow biological aerated filter and the filtering and sterilizing segment, and finally, the fecal sewage is treated to form recyclable water, so that the utilization level of water resources is greatly improved.
Description
Technical field
The utility model relates to a kind of circulating water treatment device for septic tank public lavatory.
Background technology
Current domestic Public toilets mostly is traditional lavatory, adopts septic tank to store excrement dirty, regularly extracts excrement dirt out.Because general public lavatory water consumption is larger, so cleaning cycle is very short, increase labor management cost, and for today of water resources growing tension, used in a large number tap water to flush the toilet, be the significant wastage to water resources.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of can directly utilize septic tank supernatant liquor as former water treatment become can reuse flushing water device, to reach the object of protection of the environment, saving water resource, reduction public lavatory running cost.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: for the circulating water treatment device in septic tank public lavatory, comprise urinal, septic tank, urinal is connected with septic tank; Also comprise normal temperature anaerobic biofilter, flow-raising aeration biological filtering pool, filter sterilization section and water tank; Septic tank is connected with normal temperature anaerobic biofilter, normal temperature anaerobic biofilter is connected with flow-raising aeration biological filtering pool, flow-raising aeration biological filtering pool is connected with filter sterilization section, filter sterilization section is connected with water tank, and the back flushing water outlet of water tank is connected respectively to urinal, normal temperature anaerobic biofilter and flow-raising aeration biological filtering pool; The back flushing water outlet of normal temperature anaerobic biofilter and flow-raising aeration biological filtering pool is connected to septic tank.
As preferably, normal temperature anaerobic biofilter adopts flow lifting type to process structure.
As preferably, normal temperature anaerobic biofilter adopts spherical combination biologic packing material.
As preferably, flow-raising aeration biological filtering pool adopts combined stuffing biofilm.
As preferably, filter sterilization section comprises the cotton filter core of classification PP and overflow-type ultraviolet sterilizer; The cotton filter core of classification PP is placed in overflow-type ultraviolet sterilizer the place ahead.
The beneficial effects of the utility model are:
Utilize septic tank as settling tank, normal temperature anaerobic biofilter, flow-raising aeration biological filtering pool (UBAF), filter sterilization section are passed through in water outlet successively, and final excrement sewage disposal becomes can reuse water, have greatly improved the level of utilizing of water resources.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is that the utility model is for the structural representation of the circulating water treatment device embodiment in septic tank public lavatory.
Embodiment
Fig. 1 is a kind of circulating water treatment device for septic tank public lavatory.Its working process comprises the following steps:
1, septic tank precipitation: the flushing water of urinal enters septic tank, through baffling precipitation, and natural anaerobic effect has reduced most suspended substances and has reduced part solubility organic waste.
2, normal temperature anaerobic biofilter (AF) is processed: excrement sewage, as the good sewage of biodegradability, is very suitable for anaerobic biofilter and processes.This anaerobic biofilter adopts spherical combination biologic packing material, putting into operation early stage, utilizes anaerobic activated sludge to carry out biofilm processing, and spherical combined packing surface attachment has the microbial film of one deck 1～1.5mm thickness.Water through septic tank precipitation and preliminary anaerobic treatment enters in reactor, by bacterium hydrolysis, acidifying, finally by methanogen, is converted into methane and discharges gradually.Employing flow lifting type is processed, and makes microbial film form piece, and volumetric loading is high.Utilize Controlling System regularly filler to be carried out to supercharging back flushing, guarantee that filter tank normally moves, solved flow lifting type and processed susceptible to plugging problem.
3, flow-raising aeration biological filtering pool (UBAF) is processed: the sewage of processing through AF enters UBAF and processes, and this reactor adopts combined stuffing biofilm.Most of larger molecular organics is degraded to small organic molecule in AF, enters after UBAF, by aeration effect, makes organism fully contact, degrade with microbial film.
4, filter sterilization is processed: utilize the cotton filter core of classification PP to leading portion water outlet filter, stop most of water outlet SS.Enter again overflow-type ultraviolet sterilizer, kill harmful pathogenic agent.Finally pump into storage water tank.
5, back flushing: regularly AF and UBAF are carried out to back flushing by Controlling System, the cycle is about 1-2 month, and water outlet enters septic tank through pipeline.
The feature of the present embodiment is as follows:
1, utilize the existing septic tank in public lavatory as settling tank, both cost-saving, the anaerobic effect by septic tank self has reduced subsequent disposal load again;
2, by adding the overall plan of AF and UBAF, the sewage in septic tank is reused, reduce and clear cost and save water source;
3, AF and UBAF all adopt flow lifting type to process, and have both increased reactor organic loading, have also reduced water outlet SS simultaneously.
Above-described the utility model embodiment, does not form the restriction to the utility model protection domain.Any modification of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present utility model.
