Abstract

The utility model discloses an anaerobism calcification mud filtering systems, including anaerobic reactor, anaerobic reactor's bottom is provided with pai nikou, still includes desander and recovery pond, and the input of desander is fixed with the sludge pipe, the sludge pipe with arrange mud mouth intercommunication, the bottom of desander is fixed with the sand discharge pipe of the calcification mud that is used for discharging, the top of desander is provided with the recovery tube of retrieving effective mud, the other end and the recovery pond intercommunication of recovery tube, the utility model discloses screening out with reactor's calcification mud, having let activated mud get back to reactor again and used, it is even not only to enable the reactor water distribution, still is favorable to the muddy water intensive mixing, can improve the clearance of pollutant, and for the subsequent processing process reduces pressure, the clean environmental protection of production is pollution -free.

Description

A kind of anaerobism calcification mud screening system
Technical field
This utility model is related to clean paper making technical field, especially relates to a kind of anaerobism calcification mud screening system System.
Background technology
At present, in recycled writing paper paper industry, with policy and economic double requirements, enterprise all need to implement clean manufacturing, Energy-saving and emission-reduction, with waste paper and mthod of white water from paper making cyclic utilization rate more and more higher, various ion concentration more and more highers in waste water, electricity Conductance is increasing, and particularly the calcium ions and magnesium ions of Coal Gas Washing Cycling Water accelerate anaerobic sludge calcification speed after entering anaerobic reactor Rate, the sludge activity making calcification is poor, contaminant removal capacity is low, ratio significant impact water distribution, has a strong impact on water quality of anaerobic effluent, shadow Ring anaerobic reactor treatment effect, make biochemical system be difficult to bearing load, such as discharge in system not in time, waste water is extremely difficult to Discharge standard.And now mass efficient activated sludge can only be discharged from mud discharging mouth, and in system, effective mud loss is excessive, meeting Lead to disposal ability to decline, affect subsequent treatment process.It is therefore desirable to being improved.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of anaerobism calcification mud screening system System, anaerobic reactor calcification mud and effective mud can effectively be separated by it, be avoided that large losses effective active is dirty Mud.
To achieve these goals, this utility model be employed technical scheme comprise that a kind of anaerobism calcification mud screening system System, including anaerobic reactor, the bottom of anaerobic reactor is provided with mud discharging mouth, also includes desander and recovery pond, desander Input is fixed with sludge pipe, and sludge pipe is connected with mud discharging mouth, and the bottom of desander is fixed with the row for discharging calcification mud Sandpipe, the top of desander is provided with the recovery tube reclaiming effective mud, and the other end of recovery tube is connected with recovery pond.
In further technical scheme, the bottom of described desander is provided with the flushing for washing by water to desander top Pipe.
In further technical scheme, the outfan of described recovery pond is connected with an enters mud pipe, enters mud pipe and anaerobic reaction Device connects,
In further technical scheme, between described enters mud pipe and anaerobic reactor, it is provided with sludge pump.
In further technical scheme, described sludge pipe is provided with water inlet pipe and recoil water pipe.
In further technical scheme, cyclone separator selected by described desander.
After said structure, this utility model compared to the prior art advantageously: this utility model can be by Calcification mud in reactor screens, and allows activated mud to come back in reactor and is used, and can not only make anti- Answer device water distribution uniformly, also help muddy water and be sufficiently mixed, the clearance of pollutant can be improved, be that subsequent treatment operation reduces pressure Power, produces clean environment firendly pollution-free.
Brief description
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is a kind of structural representation of anaerobism calcification mud screening system of the present utility model.
In figure:
1- anaerobic reactor, 2- mud discharging mouth, 3- water inlet pipe, 4- recoil water pipe, 5- desander, 6- flush pipe, 7- recovery pond, 8- sludge pump.
Specific embodiment
Described below is only preferred embodiment of the present utility model, does not therefore limit protection model of the present utility model Enclose.
Embodiment, as shown in Figure 1, a kind of anaerobism calcification mud screening system, including anaerobic reactor 1, anaerobic reactor 1 Bottom be provided with mud discharging mouth 2, also include desander 5 and recovery pond 7, the input of desander 5 is fixed with sludge pipe, sludge pipe Connect with mud discharging mouth 2, the bottom of desander 5 is fixed with the sediment outflow pipe for discharging calcification mud, and the top of desander 5 is provided with Reclaim the recovery tube of effective mud, the other end of recovery tube is connected with recovery pond 7.Through this system, can be by the calcium in reactor Change mud to screen, allow activated mud to come back in reactor and used.Reactor water distribution can not only be made uniformly, Also help muddy water to be sufficiently mixed, the clearance of pollutant can be improved, be that subsequent treatment operation reduces pressure.The bottom of desander 5 Portion is provided with the flush pipe 6 for washing by water to desander 5 top.The outfan of recovery pond 7 is connected with an enters mud pipe, enters mud pipe with Anaerobic reactor 1 connects, and is provided with sludge pump 8 between enters mud pipe and anaerobic reactor 1.Sludge pipe is provided with water inlet pipe 3 and anti- Jet water spout 4.Cyclone separator selected by desander 5.In anaerobic reactor 1, the mud of calcification is due to being deposited on reactor bottom than great Portion, is entered sludge pipe by the mud discharging mouth 2 of bottom using pressure differential pressure, opens water inlet pipe 3, poured mud by water inlet pipe 3 Desander 5, after entering desander 5, the current that sprayed by flush pipe 6, from bottom to top by effective dirt lighter for proportion for mud Mud and the larger calcification mud of proportion are completely separated, and the recovery tube from top for effective mud enters recovery pond 7, after precipitation, lead to Cross in sludge pump 8 feeding anaerobic reactor 1 and reuse, and calcification mud then drops to bottom by action of gravity and passes through sediment outflow Bank of tubes goes out.If any discharge pipeline clogging during reactor spoil disposal, back-flushing can be opened the purpose reaching dredging pipeline.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to this reality With new thought, all will change in specific embodiments and applications, this specification content should not be construed as To restriction of the present utility model.
