Description
Technical field
The present invention relates to water treatment field, particularly to a kind of livestock breeding wastewater defecator and method thereof.
Background technology
Livestock and poultry breeding industry is the important component part of China's agricultural economy, and it is day by day serious that it greatly develops the problem of environmental pollution brought, and not only affects economic development, and jeopardizes ecological safety. The feces of livestock and poultry farm generation and waste water cause the severe contamination of surface water, subsoil water, soil and surrounding air, directly affects the healthy and normal productive life of people. A large amount of livestock breeding wastewaters discharge, and have become as one of key factor of causing China's water pollution and eutrophication, the serious sustainable health development restricting livestock and poultry breeding industry.
In waste water of livestock poultry processing procedure, due to many containing poultry hair or not digested bulky grain lignocellulose in waste water, not only it are difficult to be degraded by subsequent biological treatment process, are also easy to cause the blocking of subsequent processing units.
Conventional defecator filter opening aperture is fixed, and in livestock breeding wastewater, solids particle diameter fluctuates relatively big over time, and conventional defecator is difficult in adapt to. And filtering residue viscosity is strong not, conventional cartridge apparatus can not consider that filtering residue can not arrive the problem of peak, causes the filtering residue always having alluvial bottom filter cylinder, and efficiency low power consuming is high.
Summary of the invention
It is an object of the invention to solve problems of the prior art, and a kind of livestock breeding wastewater defecator and method thereof are provided.
For achieving the above object, the concrete technical scheme that the present invention adopts is as follows:

As preferably, described device being additionally provided with monitoring system, for monitoring inner filter screen water level inside height in real time.
As preferably, described outer filter is identical with the filter opening aperture on inner filter screen, and on two-layer filter screen, filter opening can be completely superposed. This design can farthest increase the adjustable extent in filter opening aperture in filtering surface, substantially can realize from the of completely closed amplitude of accommodation opened to filter opening full aperture.
As preferably, between described outer filter, inner filter screen and the second sealing plate, it is equipped with fixing device. When after the filter opening overlapping area regulated on two-layer filter screen, two-layer filter screen is fixed by available fixing device, is adjusted opening fixing device when needing to regulate next time.
As preferably, being additionally provided with lower sewage sump inside described inner filter screen, lower sewage sump is arranged at below sewage sump, and is connected with down blow mouth, arrives, for collecting, the filtering residue dropped before rinsing area.
As preferably, described double-layer leaching net bottom is provided with the carrying roller supporting its weight.
Another object of the present invention is to provide a kind of livestock breeding wastewater filter method using described device, step is as follows: pending livestock breeding wastewater enters in inner filter screen by water inlet, it is trapped within filter screen by double-layer leaching net filtering residue, sewage after process enters water leg below double-layer leaching net, discharges through outlet; When filtering residue runs up to certain altitude, double-layer leaching net is driven to rotate by driving device, and by the back purge system being arranged at directly over double-layer leaching net, will be attached to the filtering residue on filter screen be flushed in sewage sump and discharge, not yet turn to the filtering residue just dropped rinsing area with filter screen and be discharged by lower sewage sump.
As preferably, according to pending livestock breeding wastewater character, adjusting the relative position of outer filter, inner filter screen in advance, the filter opening overlapping area on two-layer filter screen is adjusted to desired value.
The present invention is relative to having the beneficial effect that prior art possesses
1) double-layer leaching net being in a cylindrical shape and fitting tightly nesting is utilized to be filtered livestock breeding wastewater processing, according to needing in processing procedure, the filter opening overlapping area on two-layer filter screen can be adjusted, thus regulating filtrable grain diameter, adapt to the fluctuation of solids particle diameter in livestock breeding wastewater.
2) by monitoring inner filter screen water level inside height in real time in monitoring system, thus can feed back to control system immediately when water level is increased to a certain degree, make double-layer leaching net rotate, and be rinsed with back purge system, reduce the alluvial of filtering surface, increase the rate of filtration.
3) the filtering residue viscosity in waste water of livestock poultry is strong not, and conventional cartridge apparatus can not consider that filtering residue can not arrive the problem of peak, causes the filtering residue always having alluvial bottom filter cylinder, and efficiency low power consuming is high. The present invention is by by arranging lower sewage sump inside inner filter screen, reaching, thus collecting, the filtering residue dropped before rinsing area in double-layer leaching net rotary course. Thus being greatly reduced filtering residue alluvial phenomenon bottom filter cylinder, thus improving filter efficiency.
