Description

One way of life waste water treating and reutilizing equipment

[technical field]

This utility model relates to a kind of sewage disposal device, is specifically related to one way of life waste water treating and reutilizing equipment, belongs to technical field of environment protection equipment.

[background technology]

Sanitary sewage is found everywhere, and wherein contains substantial amounts of pollutant, if arbitrarily discharge will pollute the environment. At present, major part city is designed with sanitary sewage disposal point, and after sanitary sewage is processed, discharge is to extraneous again for it, to preserve the ecological environment.

But, the domestic sewage treatment device of prior art generally adopts the traditional approachs such as oxygenation, stirring, fermentation, precipitation that sanitary sewage is processed, and its treatment effect is very undesirable, especially to Organic substance (COD_Cr) process often not up to standard. Along with raising and the improvement of quality of life of people's living standard, legacy equipment increasingly can not meet needs.

Meanwhile, the water after the domestic sewage treatment device of prior art processes can't reach reuse requirement, causes the waste of water resource.

Therefore, for solving the problems referred to above, the life sewage treatment and reuse equipment of a kind of innovation of necessary offer, to overcome described defect of the prior art.

[utility model content]

For solving the problems referred to above, the purpose of this utility model is in that to provide a kind of simple in construction, stable, can effectively water after organics removal and process can the life sewage treatment and reuse equipment of reuse.

For achieving the above object, the technical scheme that this utility model is taked is: one way of life waste water treating and reutilizing equipment, and it includes regulating reservoir, mechanical grille, sedimentation tank, anaerobic pond, aerobic aeration pond, MBR device, clear water reuse tank and chlorine dioxide generator; Wherein, described regulating reservoir, mechanical grille, sedimentation tank, anaerobic pond, aerobic aeration pond, MBR device and clear water reuse tank are sequentially connected with; Described aerobic aeration pond and MBR device are connected to a Roots blower; Described chlorine dioxide generator is connected in clear water reuse tank.

Life sewage treatment and reuse equipment of the present utility model is further arranged to: described anaerobic pond, aerobic aeration pond, MBR device are connected to regulating reservoir respectively through a sewage backflow pipe.

Life sewage treatment and reuse equipment of the present utility model is further arranged to: be provided with effusion meter and transmissometer on the pipeline between described MBR device and clear water reuse tank.

Life sewage treatment and reuse equipment of the present utility model is also configured to: be provided with a sludge pipe bottom described sedimentation tank.

Compared with prior art, this utility model has the advantages that life sewage treatment and reuse equipment of the present utility model has simple in construction, stable, can effective organics removal, the water after process can reuse, the plurality of advantages such as saving water resource.

[accompanying drawing explanation]

Fig. 1 is the schematic diagram of life sewage treatment and reuse equipment of the present utility model.

[detailed description of the invention]

Refer to shown in Figure of description 1, this utility model is one way of life waste water treating and reutilizing equipment, and it is made up of several parts such as regulating reservoir 1, mechanical grille 2, sedimentation tank 3, anaerobic pond 4, aerobic aeration pond 5, MBR device 6, clear water reuse tank 7 and chlorine dioxide generators 8.

Wherein, described regulating reservoir 1, mechanical grille 2, sedimentation tank 3, anaerobic pond 4, aerobic aeration pond 5, MBR device 6 and clear water reuse tank 7 are sequentially connected with.

Described regulating reservoir 1 is concentrated for sanitary sewage and is stored, and plays an effect neutralizing adjustment.

Described mechanical grille 2 is for removing the big floating thing in sewage.

Described sedimentation tank 3 is for by the contamination precipitation in sewage, being provided with a sludge pipe 9, and discharged by mud by sludge pipe 9, in order to focus on bottom it.

Described anaerobic pond 4 under there is no oxygen molecule and combined oxygen existent condition, facultative bacteria and degradation of anaerobic bacteria and stable organic matter, make the organic compound of complexity be degraded, be converted into simple compound, release energy simultaneously. In this process, organic conversion is divided into two parts: a part is converted into methane, and this is a kind of fuel gas, recoverable; Some is broken down into the inorganic matters such as carbon dioxide, water, ammonia, hydrogen sulfide, synthesizes new cellular material.

Described aerobic aeration pond 5 makes to be had in sewage under molecular oxygen existent condition, makes good use of oxygen animalcule (include aerobic-anaerobic microbe but be mainly aerobic bacteria) degradation of organic substances so that it is stable, innoxious processing method. Microorganism utilizes the organic pollution (based on dissolved form and colloidal) existed in sewage to carry out oxygen metabolism for substrate, the Organic substance of these high energy positions is through a series of biochemical reaction, release energy step by step, finally settle out with the inorganic matter of mental retardation position, reach innoxious requirement.

Described MBR device 6 adopts membrane-biotechnology, it is possible to carry out efficient solid-liquid separation, overcome effluent quality in conventional activated sludge process be not sufficiently stable, the deficiency such as mud easily expansion, thus having the advantage that

1. efficiently carrying out solid-liquid separation, effluent quality is good and stable, it is achieved direct reuse;

2. efficiently it is trapped in bioreactor due to film, it is achieved reactor hydraulic detention time (HRT) and sludge age (SRT) are kept completely separate, and make operation control more stable;

3. maintaining the microbial biomass of high concentration in bioreactor, process device volumetric loading high, floor space is few; Also can design and install in outdoor underground.

4. be conducive to breeding retaining and growing of the such as nitrobacteria of microorganism slowly, system nitrification efficiency is improved, also some hardly degraded organic substances hydraulic detention time in systems can be increased, effectively the microorganism decomposing checking degradation of organic substances is trapped in reactor, is conducive to the raising of hardly degraded organic substance degradation efficiency.

Described aerobic aeration pond 5 and MBR device 6 are connected to a Roots blower 10, can to aerobic Aeration tank 5 and MBR device 6 oxygen supply by Roots blower 10.Described anaerobic pond 4, aerobic aeration pond 5, MBR device 6 are connected to regulating reservoir 1 respectively through a sewage backflow pipe 11, in order to through repeatedly processing.

Described clear water reuse tank 7 is for storing the water after MBR device 6 processes. Described chlorine dioxide generator 8 is connected in clear water reuse tank 7, and water can be carried out sterilizing by it, in order to reuse.

Further, the pipeline between described MBR device 6 and clear water reuse tank 7 is also equipped with effusion meter 12 and transmissometer 13, controls MBR device 6 by effusion meter 12 and go out water speed, it is ensured that depuration quality; And be used for detecting recycle-water turbidity by transmissometer 13, judge, with this, the quality that purifies water.

Above detailed description of the invention is only the preferred embodiment of this creation, not in order to limit this creation, and any amendment of making within all spirit in this creation and principle, equivalent replacement, improvement etc., should be included within the protection domain of this creation.
