| 摘要 |
The present invention provides treatment of wastewater containing oil, organic and inorganic industrial compounds, urea, and e.t.c. The resulting products will be purified water, dry fertilizer, pure carbomide, uncontaminated gas and liquid fuel, and other products that can be separated from the concentrate after ultrafiltration. In order to accomplish those and other objectives the present invention improves the system for cleaning wastewater by subjecting the wastewater to a magnetic field and heating it before the initial settling process. In addition, before ultrafiltration, the liquid is treated in an electroflotation device. The wastewater cleaning system can also be comprised of a urea separator for separating urea from other products.
