Background technology
At present, the process of China's changing food waste is mainly based on anaerobic fermentation, and the zymotic fluid concentration after fermentation is lower, and granularity is less, after usually adding flocculant, and processed.Later stage interpolation stalks etc. are modified, for the production of Nutrition Soil or fertilizer.Changing food waste is as emerging industry, and current income is lower, how to reduce cost of disposal, is the major issue that changing food waste treatment industry needs to solve.
At present, existing dehydration technique adopts flocculant flocculation, then adopts dehydration equipment dehydration.Flocculant many employings cationic flocculant, cost is higher.Due to the characteristic in kitchen of eating, after anaerobism, the addition of flocculant is comparatively large, is about the 5-6 ‰ of oven-dry weight, the price of the cationic flocculant of existing market is about 2-3 ten thousand yuan/ton, therefore for changing food waste treatment industry, the cost of flocculant is comparatively large, directly affects whole changing food waste processing cost; And only add flocculant, containing more ion in the percolate after dehydration, the ion in percolate needs to process in follow-up sewage disposal, thus increases the cost of post processing.
To sum up, there is the high problem of processing cost in existing changing food waste dewater unit.
Utility model content
The utility model is solve existing changing food waste dehydration equipment to there is the high problem of processing cost, and then provides a kind of mixed dehydration device utilizing stalk to replace flocculant.
The utility model is solve the problems of the technologies described above the technical scheme taked to be:
The stalk that utilizes of the present utility model replaces the mixed dehydration device of flocculant to comprise double helix exrusion dewaterer, single-screw extruding-desiccation machine and natural pond liquid collecting box, single-screw extruding-desiccation machine is horizontally set on directly over the liquid collecting box of natural pond, the bottom of single-screw extruding-desiccation machine is provided with screen cloth along its length, double helix exrusion dewaterer is inclined at directly over single-screw extruding-desiccation machine, one end of double helix exrusion dewaterer is provided with charging aperture, the other end of double helix exrusion dewaterer is provided with discharging opening, charging aperture is lower than the discharging opening of double helix exrusion dewaterer, the discharging opening of double helix exrusion dewaterer is communicated with the top of single-screw extruding-desiccation machine by the first pipeline, the bottom of double helix exrusion dewaterer is processed with draining hole, the draining hole of double helix exrusion dewaterer is connected with natural pond liquid collecting box by the second pipeline.
The utility model compared with prior art has following beneficial effect:
Double helix exrusion dewaterer, single-screw extruding-desiccation machine and the natural pond liquid collecting box utilizing stalk to replace the mixed dehydration device of flocculant of the present utility model becomes one up and down, through two-stage extrusion dehydration, the 40-50% of the dry mud amount of adsorbable dehydration, saves the flocculant of 40-50%; Shorten process distance simultaneously, save the conveying equipment between dewaterer, reduce follow-up flocculation cost, greatly reduce processing cost, save and take up an area space;
The stalk that utilizes of the present utility model replaces the mixed dehydration device of flocculant in changing food waste post processing dehydration, cheap dry straw is adopted to substitute expensive cationic flocculant, adsorbed and crown_interception by stalk, increase natural pond solid and liquid separative efficiency, reduce the content of suspension in the liquid of natural pond, make stalk be processed simultaneously, shorten the time of the later stage natural pond slag utilization of resources; And by adopting stalk to substitute flocculant, reducing chemical oxygen consumption (COC), biochemical oxygen demand (BOD), ammonia nitrogen, solid content index in sewage, reducing sewage treatment load.
