Abstract
The utility model discloses a sludge pretreatment device, including preliminary treatment pond, oil mist separation jar and collection tank, the exit end in preliminary treatment pond with the bottom inlet connection of oil mist separation jar, the top exit end of oil mist separation jar with the collection tank is connected, be provided with on the exit end in preliminary treatment pond and float oil trap. The utility model discloses a set up preliminary treatment pond and oil mist separation jar, can reduce the content of the greasy dirt dissolubility organic matter in the mud, improve the biodegradability ability of mud, get rid of the silt content in the mud flco simultaneously, be favorable to subsequent sludge treatment and processing, simple structure, convenient to use.
Description
Technical field
The utility model relates to a kind of pretreatment unit, refers more particularly to a kind of sludge pretreatment device.
Background technology
Outer polymkeric substance (EPS) is the chief component of active pollution index, directly be covered in outside bacteria cell wall, the number of its quantity and the change of component can have an impact to the surface property of active pollution index, and then affect the Adsorption and flocculation performance of active sludge, thus finally have influence on the efficiency of biological sewage treatment.Containing materials such as polysaccharide, protein and lipids in EPS, make the electronegative main component of Sludge Surface, therefore in sewage treatment process, EPS has adsorbed two a large amount of trivalent metal cations, and these metallic cations have important effect for the physics-chem characteristic of mud flco especially extracellular polymeric.
Utility model content
It is simple that the purpose of this utility model is just to provide a kind of structure to solve the problem, and improves the sludge pretreatment device of the biodegradability energy of mud.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises pretreatment pool, mist of oil separating tank and holding tank, the exit end of described pretreatment pool is connected with the bottom inlet end of described mist of oil separating tank, the top exit end of described mist of oil separating tank is connected with described holding tank, and the exit end of described pretreatment pool is provided with floating-oil collector.
Particularly, described floating-oil collector comprises collects valve and multiple ball float, and described ball float is arranged on described collection valve in order to control the collection height of described collection valve.
Further, gas-liquid mixing pump, reverse flow valve and recycle valve is provided with between described pretreatment pool and described mist of oil separating tank.
Particularly, be provided with baffle plate in described mist of oil separating tank, the bottom of described mist of oil separating tank is provided with sludge outlet.
Further, the bottom of described pretreatment pool is provided with agitator.
The beneficial effects of the utility model are:
The utility model, by arranging pretreatment pool and mist of oil separating tank, can reduce the content of the greasy dirt dissolved organic matter in mud, improves the biodegradability energy of mud, remove the sediment concentration in mud flco simultaneously, be conducive to follow-up sludge treatment and disposal, structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-dosing mouth, 2-gas-liquid mixing pump, 3-reverse flow valve, 4-baffle plate, 5-holding tank, 6-pretreatment pool, 7-ball float, 8-collects valve, 9-agitator, 10-recycle valve, 11-sludge outlet, 12-mist of oil separating tank.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises pretreatment pool 6, mist of oil separating tank 12 and holding tank 5, the exit end of pretreatment pool 6 is connected with the bottom inlet end of mist of oil separating tank 12, the top exit end of mist of oil separating tank 12 is connected with holding tank 5, and the exit end of pretreatment pool 6 is provided with floating-oil collector.
Floating-oil collector comprises collects valve 8 and multiple ball float 7, and ball float 7 is arranged on to be collected on valve 8 in order to control to collect the collection height of valve 8.
Be provided with gas-liquid mixing pump 2, reverse flow valve 3 and recycle valve 10 between pretreatment pool 6 and mist of oil separating tank 12, be provided with baffle plate 4 in mist of oil separating tank 12, the bottom of mist of oil separating tank 12 is provided with sludge outlet 11, and the bottom of pretreatment pool 6 is provided with agitator 9.
Principle of work of the present utility model is as follows:
Mud after fluidisation in pretreatment pool 6 adds EDTA solvent medicament by dosing mouth 1 and regulates mud PH value according to the characteristic of sludge slurry, agitator 9 stirring reaction, there are some researches show when active pollution index is placed in the buffered soln containing EDTA, the metal ion of Sludge Surface is fallen by complexing, the surface charge of mud is caused to reduce, Zata current potential declines, bacterium is caused to discharge electronegative polysaccharose substance, therefore, when reducing the concentration of metal ions in mud, the polysaccharose substance etc. of more negatively charged can be discharged, thus add the content of dissolved organic matter, when starting floating-oil collector after sludge slurry static layering, the greasy dirt on upper strata is drawn in mist of oil separating tank 12 by gas-liquid mixing pump 2, baffle plate 4 can play and intercepts the mud dregs that mix and discharge from sludge outlet 11, water-refilling operation can be carried out by pressure opening circulating valve 10 when liquid is very few in pretreatment pool 6 time, if recovery greasy dirt impurity too much can be opened reverse flow valve 3 and carry out secondary circulation separation, last isolated fluid can enter holding tank 5 and carry out the process of next workshop section.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection domain of the present utility model.
