Description

The anaerobic baffled reaction unit of drum type brake

The utility model relates to a kind of high-load anaerobic biological treatment device that is used for waste water or sewage.It can be used for handling waste water or the sewage that contains middle and high concentration organic pollutant especially.

At present, the anaerobic biological treatment device that is used for waste water or sewage, as the UASB reactor of inventing and being widely used by Dutch professor Lettinga of agriculture university, this reactor can be seen from the synoptic diagram of 3 figure, it contains the cylinder 1 of the band conical bottom of a band waste water inlet pipe 11, pure water inlet pipe 13, methane outlet pipe 14, and the cylinder top has three-phase separating device 4.Waste water enters cylinder 1 from the waste water inlet pipe 11 of bottom, and in the uphill process, successively by Sludge Bed district, sludge suspension floor district and three-phase separation area, last biogas and water are drawn from top methane outlet pipe 14, pure water inlet pipe 13 respectively in tube.This UASB reactor also has following weak point: 1) when load was higher, more anaerobic activated sludge was taken away in top direct draining meeting, made processing efficiency reduce by 2) also there is certain dead angle in this reactor, thus the effective volume load is descended; 3) to containing the sewage disposal of higher suspended sediment concentration, cause the obstruction of three-phase separating device and water port easily, thereby cause difficult treatment.

Also has a kind of anaerobic biological treatment device that is used for waste water or sewage at present, as anaerobic baffled reactor, it can be seen in the synoptic diagram from Fig. 4, have waste water inlet pipe 11 on its housing 1, pure water inlet pipe 13, methane outlet pipe 14, it is horizontally disposed, and the polylith baffle plate is set at Transverse to the flow direction, with upward flow chamber that reactor is being divided at interval with down to the stream chamber, wherein the upward flow chamber is than wide to the stream chamber down, and the flow deflector 16 ' that has 50 ° of inclination angles in the baffle plate bottom that leads to the upward flow chamber, so that water is delivered to the center of upward flow chamber, make active sludge, the sewage thorough mixing.The shortcoming of this device is that processing efficiency is low, improves the load difficulty, and the sludge stream vector is bigger, mud, water distribution inequality.In a word, above-mentioned two kinds of reactors are to handling high concentration organic sewage, as BOD ₅When=1000～40000mg/L and greater concn, its efficient is just undesirable.

The purpose of this utility model is to overcome the shortcoming that exists in the above-mentioned prior art, provide a kind of can the processing contain the waste water of middle and high concentration organic pollutant or the anaerobic baffled reaction unit of drum type brake of sewage, so that it has high-level efficiency, high loading and characteristics such as simple in structure, easy to use.

The anaerobic baffled reaction unit of the utility model drum type brake, it contains the cylinder of the band conical bottom of a band waste water inlet pipe, sludge outlet pipe, pure water inlet pipe, methane outlet pipe, be characterized in: be equipped with in the cylinder one group with the concentric annulus post that is solidified as a whole at the bottom of it, and between the adjacent two annulus posts in the contained space, having installed one with one heart can divide the space into the upward flow chamber and down to the annulus guide pillar of stream chamber, leave the gap between the inwall at the bottom of the bottom of annulus guide pillar and the cylinder.

The anaerobic baffled reaction unit of the utility model drum type brake, contained spatial volume equates between the interior adjacent two annulus posts of cylinder, and equals the contained spatial volume of annulus post of cylinder center; Upward flow chamber and down unequal to the volume of stream chamber, and the volume of upward flow chamber is greater than down to the stream chamber.

The anaerobic baffled reaction unit of the utility model drum type brake, the bottom of annulus guide pillar have water conservancy diversion and tiltedly enclose, and the contained spatial height of annulus post and the diameter ratio that are positioned at cylinder center can be 4-6, preferably 3-5 of the quantity of annulus post.

The anaerobic baffled reaction unit of the utility model drum type brake in use, containing the waste water of middle and high concentration organic pollutant or the sewage waste water inlet pipe at center at the bottom of the cylinder enters, the fluid dividing cover and the baffle that are provided with through its pipe end enter the annulus column space R1 that is positioned at cylinder center, this space is anaerobic reactor R1 just, sewage mixes, contacts, reacts at this with anaerobic activated sludge, meanwhile constantly rise again, behind separator, arrive the top of the annulus post at center, outwards overflowed into the space R2 that two annulus posts are surrounded thus; This space that is reactor R2, this fluid be introduced into by the annulus guide pillar be separated into following to stream indoor flowing downward, then from the water conservancy diversion of annulus guide pillar bottom tiltedly at the bottom of circle and the cylinder gap between the inwall change the upward flow chamber over to, upwards the top end to the annulus post promptly overflows into the space R3 that another is surrounded by two annulus posts in this chamber, be reactor R3, after this flow process in the reaction repeated device R2 again in it enters the space R4 that another annulus post and cylinder inner wall are surrounded, i.e. reactor R4 again again; Sewage and anaerobic activated sludge this carry out last mixing, contact, after the reaction, overflow into effluent weir from the cylinder inner wall top, pure water inlet pipe by the effluent weir bottom flows out, and biogas when the turning to of fluid each reactor R1, R2, R3, R4 top separated upwards, and in the top cover of band awl, assemble the back and draw from the methane outlet pipe.

The utility model has the advantages that: 1) the anaerobic baffled reaction unit of the utility model drum type brake can include one group of reactor of connecting in a cylinder, make waste water or sewage by each reactor the time, repeat to flow downward fast, upwards flow at a slow speed, realize that waste water and repeatedly mixing repeatedly of mud contact, constantly carry out the anaerobe reaction, thereby realized high-level efficiency, high loading, therefore made it can be used to handle waste water or the sewage that contains middle and high concentration organic pollutant waste water or biological sewage treatment; 2) the entire treatment process of the utility model device is to carry out in the tandem reactors of sealing for anaerobic sludge, so its loss is less; 3) the compact construction volume of whole device is little, and easy to use, reliable.
