Embodiment
Embodiment 1:
As shown in Figure 1, as Fig. 1 be the structural representation of the utility model low load applications.
Be applicable to that the COD load is low as the following situation of 5kg/m3.d.Its operation condition such as UASB, difference is: horizontal plural serial stage structure, air water separator need not be set, in the end one-level is provided with settling tank, keeps mud.
Anaerobic biochemical reactor has a rectangle form pool body 1, between the pond body 1 dark 5-12m all can, can be divided into A, B, C in this pond body 1 ... multistage locellus such as Y.Each locellus A, B, C ... be provided with down in the Y to runner 11 and upward flow road 21 and form.
Be cascaded structure between each multistage locellus, every grade has specific reacting phase, i.e. biology and matrix, reaction efficiency height; Series-mode frame can increase impact resistance, and the reaction period is provided;
During work, sewage enters the descending runner 11 of first locellus A from water inlet pipe 2, after bottom water distribution system 31 is distributed, change upward flow road 21 over to,, produce anaerobic biochemical reaction this and the suspension that has formed or anaerobic mud bed contact of expanding, and there is biogas to produce, after free surface place gas-liquid natural separation, sewage flows into next locellus B, locellus C successively, entering into last locellus again is that water-supplying chamber Y1 place discharges through rising pipe 3, sewage anaerobe purification therebetween.In the Y of water-supplying chamber, be provided with settling tank 7, can precipitated outlet water in suspended substance be said biological mud, ensure that mud does not run off; The biogas that produces in the biological process is collected through vapor pipe 4 and is discharged, and surplus mud is got rid of through shore pipe 5.
