Description
Technical Field
The utility model relates to a degree of depth degritting processing field of organic rubbish thick liquids especially relates to a degree of depth degritting device for organic rubbish thick liquids.
Background
Organic garbage, namely wet garbage (kitchen garbage, tailstocks, fruit and vegetable garbage, livestock and poultry manure and the like), is treated by anaerobic fermentation in a common treatment main process method. Anaerobic fermentation is a process of performing biodegradation on organic matters by relying on biochemical actions of facultative anaerobes and obligate anaerobes under the condition of isolating contact with air; the slurry quality of anaerobic fermentation is improved, impurities in the slurry, particularly impurities with the density of sand, etc. being higher than that of water, are thoroughly removed, so that the long-term stable work of the anaerobic fermentation reactor can be guaranteed, the corrosion resistance damage in the reactor tank body is reduced, the volume reduction of the effective volume of the tank body and the blockage of a pipeline are reduced, and the service life of the anaerobic fermentation reactor and the service life of a matched pipeline, a pump and a valve are prolonged.
Therefore, before anaerobic fermentation, preliminary pretreatment processes such as removing large impurities, separating, crushing and the like are required, and after the pretreatment processes and the organic wastewater with high concentration, high grease and high sand content generated by the pretreatment processes are prepared into organic slurry, anaerobic fermentation treatment is carried out. However, the organic waste has very complicated and various components, and the organic slurry prepared by the pretreatment is high-concentration sand-containing organic wastewater which contains more substances with higher density such as fine gravel, broken eggshell, broken glass, bone slag and the like, so that the treatment equipment, oil-water separation equipment, pumps, valves, pipelines and the like are greatly abraded in the subsequent treatment process, and the problems of pipeline blockage and the like are easily caused; meanwhile, the excessive and overlarge particle size of the organic matters can cause the risks of impurity accumulation and volume reduction in the anaerobic fermentation tank and reduction of anaerobic biogas production rate at the rear end or production stop of tank cleaning.
The prior common sand removing treatment equipment has poor sand removing effect on the organic slurry, incomplete grit separation, frequent damage to equipment, pipelines and the like, large workload of maintenance, repair and replacement, and accidents of shutdown and overhaul and the like.
For example, a sand-water separator is applied in the kitchen waste treatment plant of Beijing Dagongcun, and is used for separating kitchen waste leachate, and the structure that the upper part of a conical box body discharges liquid and the bottom of the conical box body spirally inclines to discharge sand is adopted. Through use, the device is not thorough in sand removal, a large amount of water is discharged along with the sand during sand production, and the sand content of the discharged liquid is too large, so that subsequent separation equipment is easy to block and wear, and the device is frequently stopped for maintenance.
For another example, a kitchen waste treatment plant with double flows in Chengdu uses a sand removal device combining a cyclone separator and a sand-water separator, and the device also has the problems of overlarge sand content of the discharged liquid, easy blockage and abrasion of subsequent separation equipment and the like in actual use.
In summary, in the field of deep desanding treatment of organic waste slurry, an integrated multiple desanding device capable of effectively separating inorganic impurities from slurry and having deep and fine desanding (desanding) functions is lacking.
