Abstract

The utility model discloses gas-stripping type sludge lifting equipment. The gas-stripping type sludge lifting equipment comprises a box body (10), wherein a settling chamber and a contact chamber are arranged in the box body (10); a sludge reflux tube joint (9) is arranged on the top of the contact chamber; a gas inlet tube joint (6) and a sludge tube joint (7) are arranged on the top of the settling chamber; one end of the sludge tube joint (7) is communicated with the sludge reflux tube joint (9); the upper end of the gas tube joint (6) is connected with an external gas pump; a sludge suction plate (9) is arranged on the bottom of the settling chamber; a gas-stripping tee joint (3) is arranged in the settling chamber; the bottom joint of the gas-stripping tee joint (3) is connected with the sludge suction plate (2); one of the other two joints is connected with the lower end of the gas tube joint (6), and the other joint is connected with the other end of the sludge tube joint (7). The gas-stripping type sludge lifting equipment provided by the utility model drives flow of active sludge to form reflux by virtue of flow of a gas, so that recycling of the active sludge is realized.

Description

A kind of gas stripping type sludge lifting equipment
Technical field
The utility model relates to a kind of gas stripping type sludge lifting equipment.
Background technology
As everyone knows, sanitary sewage disposal is mainly to utilize taking aerobic bacteria as main active sludge cenobium to form as the sticking flco adsorb organic compound of flocculence band matter, under aerobic condition, clear up organic substance and become harmless carbonic acid gas and water, active sludge is bred simultaneously, thereby, active sludge is the place of the key of sewage disposal, but because active sludge becomes flocculence, be flow state at sewage, in operation circulation process, having part active sludge can be brought to settling chamber from exposure chamber by current, after certain hour, can form alluvial in bottom, settling chamber.Meanwhile, because the organism containing through former procedures water after treatment in sump tank is little, be not enough to maintain the aerobic bacteria existence in active sludge, active sludge finally becomes the dead mud in stand, thereby has polluted settling chamber.
Summary of the invention
In order to address the above problem, the utility model provides a kind of gas stripping type sludge lifting equipment, and flowing of the fluxion strap activated sludge by gas, forms and reflux, and realizes the cycling and reutilization of active sludge.
The utility model has adopted following technical scheme: a kind of gas stripping type sludge lifting equipment, it comprises casing, in casing, be provided with settling chamber and exposure chamber, the top of described exposure chamber is provided with sludge reflux tube stub, the top of described settling chamber is provided with inlet pipe joint and sludge pipe joint, one end of described sludge pipe joint is communicated with sludge reflux tube stub by mud return line, and the upper end of described gas fittings is connected with external air pump; Bottom in settling chamber is provided with mud sucking disk, in settling chamber, be provided with air lift threeway, the bottom fitting of described air lift threeway is connected with mud sucking disk, and two other connects first and is connected with the lower end of gas fittings by inlet pipe, and another is connected with the other end of sludge pipe joint by sludge lifting pipe.
Described mud sucking disk is fixed on the bottom of casing settling chamber by fixed support.
The utlity model has following beneficial effect: flowing of the fluxion strap activated sludge of the utility model by gas, form and reflux, realize the cycling and reutilization of active sludge.Gas source, from the oxygen supply air pump of waste disposal plant self configuration, has realized utilization of resources maximization.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of gas stripping type sludge lifting equipment, it comprises casing 10, in casing 10, be provided with settling chamber and exposure chamber, the top of described exposure chamber is provided with sludge reflux tube stub 9, the top of described settling chamber is provided with inlet pipe joint 6 and sludge pipe joint 7, and one end of described sludge pipe joint 7 is communicated with sludge reflux tube stub 9 by mud return line 8, and the upper end of described gas fittings 6 is connected with external air pump; Be provided with mud sucking disk 2 in the bottom of settling chamber, described mud sucking disk 2 is fixed on the bottom of casing 10 settling chambers by fixed support 1, in settling chamber, be provided with air lift threeway 3, the bottom fitting of described air lift threeway 3 is connected with mud sucking disk 2, two other connects first and is connected with the lower end of gas fittings 6 by inlet pipe 5, and another passes through sludge lifting pipe 4 and is connected with the other end of sludge pipe joint 7.
