Description
Technical field
The present invention relates to environmental technology fields, and in particular, to a kind of anaerobic reactor and waste water for handling waste water
Anaerobic treatment process.
Background technology
Anaerobic reactor is the commonly used equipment for handling waste water, and anaerobic sludge of the anaerobic reactor inside is by waste water
In COD processing be converted to biogas.Contain impurity, such as fiber (cow dung water), stalk etc. in waste water.In order to will be inside fiber etc.
COD be converted to biogas much more as possible, to generate certain upflow velocity in anaerobic reactor, improve Anaerobic Treatment effect
Fruit, waste water are usually pre-processed without fiber before entering in anaerobic reactor.Waste water is with anaerobic sludge mixing uniformity
An important factor for influencing treatment effect, improves treatment effect, in anaerobic reaction in order to enable waste water is uniformly mixed with anaerobic sludge
It is usually stirred in device.However, there is a problem of respective using the method that stirring improves mixed effect, there are improved need
It asks.
Invention content
The application is made to the discovery of following facts and problem and understanding based on inventor:
The stirring of anaerobic reactor has following several agitating modes:(1) compressed gas stirs:By into anaerobic reactor
Conveying compressed gas is stirred.This agitating mode is the problem is that high energy consumption, the security requirement to anaerobic reactor
It is high.(2) circulating pump stirs:The waste water of anaerobic reactor internal upper part is pumped into the lower part in anaerobic reactor by circulating pump,
For generating upward flow velocity, to rush waste water and sludge upwards, there is also stirring dead zones for this circulating pump agitating mode.
(3) mechanical agitation, i.e., be arranged stirrer paddle in anaerobic reactor, and stirrer paddle is led to by being located at the motor at the top of anaerobic reactor
Cross transmission shaft driving rotation.It needs to drive stirrer paddle by long transmission shaft due to being located at the motor at the top of anaerobic reactor,
Since the height of anaerobic reactor is usually larger, there is vibration greatly, the unstable problem of stirrer paddle.Stirrer paddle distance
The distance of anaerobic reactor inner bottom surface is usually the one third of anaerobic reactor height, if stirrer paddle apart from inner bottom surface too
Closely, then the loss of energy is stirred, energy consumption and cost are increased, if stirrer paddle is too far apart from inner bottom surface, anaerobic reactor bottom holds
Easily there is stirring dead zone (region that can not be stirred to), influences mixed effect.
Further, since sludge is easy to be deposited on the inner bottom surface of anaerobic reactor, traditional agitating mode can not be fine
Ground stirs the sludge on inner bottom surface, to influence the mixed effect of sludge and waste water.
Present invention recognize that it is above-mentioned tradition stirring there are the problem of, it is intended to solve at least to a certain extent in the related technology
One of the technical issues of.For this purpose, the present invention proposes a kind of anaerobic reactor and waste-water anaerobic treatment process, the anaerobic reactor and

Sludge on the bottom surface of the reative cell is scraped in the mud-collecting slot being located on the bottom surface using mud scraper, the mud scraper
Including cleaning shoe and it is located at driving device of the anaerobic reactor bottom for driving the cleaning shoe;
The reative cell is discharged in sludge in the mud-collecting slot.
19. waste-water anaerobic treatment process according to claim 18, which is characterized in that further including will be out of described mud-collecting slot
At least part sludge of discharge is along the top for being tangentially pumped into the reative cell of the reative cell.
20. waste-water anaerobic treatment process according to claim 19, which is characterized in that at least part sludge is pumped
It is sent to above the indoor liquid level of reaction, the waste water is by being tangentially supplied in the reative cell along the reative cell.
