According to most of our farmers currently using waste water directly. But there are large quantities of water, a large loss of shortcomings. According to strengthen the new rural construction requirements and people's awareness of energy conservation and environmental protection, and now farms built and biochemical pool handle manure digesters, but manure into biogas class materials are not solid-liquid separation, the actual use of such direct proof biogas train less than ideal. Because untreated waste water into the digester, greatly increasing the amount of organic load digester unit volume, and therefore to increase the number of digester volume. Because long-term use of biogas, a lot of residue left after fermentation, so digesters blockage caused by reduced capacity digesters can not be used while cleaning the pool that is labor-intensive and very unsafe, while increasing expenses. If the direct sales of fresh manure and very difficult to transport. Therefore, we should find that the former pig liquid separation measures can solve the problem in manure digesters precipitation, greatly enhanced processing power digesters, biogas can be greatly reduced, biochemical pool construction area. Saving environmental treatment of capital investment and land use area, isolated from pig manure can be directly used as fruit trees, forest fertilization and organic fertilizer raw materials. Sold as organic fertilizer organic fertilizer plant material or self-made organic fertilizer, so there are both social and economic benefits. This machine can be widely used as chicken, cattle, horses and all kinds of intensive farms separation of liquid animal waste residue, lees, dregs, starch residue, slag sauce, slaughter plants, high concentrations of organic wastewater. Applicability: This series machine slag liquid separation speed, fecal residue moisture separated by between 50-60%, the amount of slag and moisture adjustable, suitable feed different components (such as grass and fodder) , easy to transport, the solid particulate matter is very suitable as fish feed and organic fertilizer raw materials. Advanced: This series machine decontamination capability, no plug for easy cleaning. After removal of solids waste water treatment rate, chemical oxygen demand, total oxygen consumption, nitrogen and phosphorus can be between 70-95%. Durability: This series of machine frame, screen frame, screen and so on stainless steel and anti-corrosion treatment is made, corrosion resistance, high strength, long service life. Economy: The series of high degree of automation, low power consumption, low prices. Easy to operate simply press the button to start and stop operation.
