Abstract
The utility model discloses a hydrolysis acidification pool, comprising processing single pools, wherein the hydrolysis acidification pool comprises at least three processing single pools which are adjacently and/or oppositely arranged; the processing single pools are communicated through channels; a stirring device and a water inlet and outlet control valve are arranged inside each processing single pool; the stirring devices are umbrella stirring disks of which the surfaces are provided with a plurality of arch plug flow ribs; and a current stabilizer is arranged below the liquid level of each processing single pool. The hydrolysis acidification pool of a settling pond does not need to be arranged separately; and the stirring device disclosed by the utility model can come into full contact with cement without a dead angle during the stirring process.
Description
Technical field
The utility model relates to a kind of continuous hydrolysis acidification pool that omits settling tank.
Background technology
Mud method acidication technique, in the pond, the high density anaerobe is that active sludge comes adsorption-decomposition function COD to anaerobic fixed film reactor by keeping, for active sludge being run off and keeping high sludge concentration in hydrolytic tank, settling tank with treatment capacity is set in the hydrolytic tank back usually, by the post precipitation mud-water separation with sludge reflux, guarantee the impact that in hydrolytic tank, biological concentration changes to adapt to the water yield, namely be hydrolyzed biochemical reaction and precipitate and separate mud and fixedly complete in two separate tanks respectively.Chinese patent CN1693233 tech. for treating urban sewage by complete mixed hydrolytic acidify for example, municipal effluent is sent into hydrolysis acidification pool, stir, the sewage of discharging from hydrolysis acidification pool enters settling tank, and sludge reflux is arrived hydrolysis acidification pool, enter follow-up aerobic treatment operation from settling tank sewage out.Mud method acidication need arrange with the treatment capacity settling tank, and sludge reflux system (reflux pipeline and refluxing unit) need be set, and has increased occupation of land and construction costs, and working cost; Secondly, trade effluent content is higher in sewage, and difficult degradation dissolved organic matter content is higher and toxic to microorganism, the loose not free settling of biological floe that causes hydrolysis to generate, common precipitate and separate is difficult to reach required sludge concentration, even reach required sludge concentration and be mainly also the inorganic particle suspended substance in water, cause sludge activity lower, thereby affect hydrolysis effect; Besides, due to the hydrolysis biochemical reaction be directly intake at a hydrolysis acidification pool, water outlet, the Inlet and outlet water short circuit phenomenon can appear when stirring is short of power, can not guarantee full pond sludge concentration homogeneity, also can affect treatment effect, cause the impact to follow-up continuous operation aerobic system.
The utility model content
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, and a kind of hydrolysis acidification pool that does not need to arrange separately settling tank is provided, and the whipping appts that the utility model provides can fully contact with cement, stirs without the dead angle.
For realizing the utility model purpose, provide following technical scheme:
A kind of hydrolysis acidification pool, comprise and process single pond, described hydrolysis acidification pool has three adjacent and/or be oppositely arranged processing list ponds at least, described processing is passed through channel connection between single pond, be respectively equipped with whipping appts and inlet and outlet control valve door in the single pond of described processing, described whipping appts stirs disk for there is the umbrella shape of some arc plug-flow convex tendons on the surface, and there is constant-current stabilizer liquid level below, the single pond of described processing.
Further, described inlet and outlet control valve door is electric control valve.
Further, described whipping appts is by time variable control working time and/or operation stirring intensity.
Further, the single pond of described processing is rectangular.
The contrast prior art the utlity model has following advantage:
The utility model is a kind of hydrolysis acidification pool that does not need to arrange separately settling tank, and the whipping appts that the utility model provides can fully contact with cement, stirs without the dead angle.
Description of drawings
Fig. 1 is the structural representation of the hydrolysis acidification pool that provides of the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
as shown in Figure 1, a kind of hydrolysis acidification pool, comprise and process single pond 1, described hydrolysis acidification pool has three adjacent and/or be oppositely arranged processing list ponds 1 at least, be communicated with by passage 2 between the single pond 1 of described processing, the single pond of described processing is preferably rectangular, process and be respectively equipped with whipping appts 3 and inlet and outlet control valve door in single pond 1, described inlet and outlet control valve door is preferably electric control valve, described whipping appts 3 stirs disk for there is the umbrella shape of some arc plug-flow convex tendons 5 on the surface, described whipping appts is by time variable control working time and/or operation stirring intensity, below 1 liquid level of the single pond of described processing, constant-current stabilizer 4 is arranged.
Hydrolysis acidification pool of the present utility model, stir by hydrolytic process being divided into water inlet at least, quiescent setting, three processes of water outlet are carried out in turn, and three processes are carried out at least simultaneously in three or above different pond, realize continuous hydrolysis by continuous flow, the acidication whole process is separately carried out in three or the above separate tanks that more adapts to each stage condition of acidication, have better hydrolysis effect.Namely when continuous hydrolysis, at least always have a pond to be in into water and mix, a pond is in quiescent setting, and a pond is in water state, and each treating pond forms continuous flow by communicating pipe or canal and moves continuously; And three processes of hydrolysis are moved in each separate single pond continuously in alternate cycle in treating processes.Simply say, in the continuous hydrolysis treating processes, at least three separate tanks are three processes that are hydrolyzed simultaneously, in a treating pond be in chronological sequence in turn order criticize the hydrolysis three processes.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, although with reference to above-described embodiment, the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can modify or be equal to replacement embodiment of the present utility model, and do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of claim scope of the present utility model.
