The invention provides a comprehensive treatment method for gold-copper-containing smelting wastewater, and belongs to the technical field of wastewater treatment. The method comprises the following steps: adding reduced iron powder into the gold-containing copper smelting wastewater, and fully reacting to obtain an iron powder replacement turbid solution; a first pH value regulator is added into the iron powder replacement turbid solution, an oxidizing agent is added after the pH value is regulated, and an iron-removed turbid solution is obtained after full reaction; adding a flocculating agent into the iron-removed turbid liquid, fully flocculating, and carrying out solid-liquid separation to obtain iron-removed underflow and iron-removed overflow; carrying out filter pressing dehydration treatment on the iron-removed underflow to obtain gold-copper slag and filter pressing liquid; and mixing the iron-removed overflow and the press filtrate, adding a second pH value regulator, and fully reacting after regulating the pH value to obtain a neutralized turbid solution. By means of the mode, valuable substances are effectively recycled, meanwhile, harmful metal ions in the wastewater are prevented from affecting a production system or the ecological environment, hazardous waste is not generated in the whole process, and unification of environmental benefits and economic benefits is achieved.

When cylindrical raw materials need to be machined in the actual production and use process, the raw materials can be installed on a clamping rotating part, then the needed turning amount is adjusted by adjusting the distance between a knife on a knife rest and the raw materials, then a driving mechanism is operated, and the cylindrical raw materials can be machined. The driving mechanism drives the tool rest to get close to the raw materials, the raw materials are driven by the clamping rotating part to rotate at a high speed, the tool turns the raw materials, and remaining materials obtained after turning fall onto the first telescopic protection plate and the second telescopic protection plate. Large excess materials roll into the recycling box along with the first telescopic protection plate and the second telescopic protection plate to be collected, so that the large excess materials cannot fall onto the longitudinal slide carriage to cause damage, and when fine excess materials on the first telescopic protection plate and the second telescopic protection plate need to be recycled, the blowing mechanism can be operated to blow the excess materials into the recycling box. And the blowing mechanism blows the finely-crushed excess materials into the recycling box to be collected.

The utility model relates to the technical field of garment processing equipment, in particular to a garment covering machine with a waste collecting function, which comprises a covering machine seat and a covering machine, an operating table is arranged on the top surface of the covering machine seat, and the top surface of the operating table is fixedly connected with the covering machine. A driving guide rail and a driven guide rail are fixedly arranged on the front face and the back face of the covering machine base operation table respectively, a translation plate is slidably arranged on the front face of the driving guide rail, a roller frame is fixedly welded to the front face of the translation plate, a driven block is slidably arranged on the top face of the driven guide rail, and a sweeping roller is arranged between the driven block and the roller frame. A storage groove is fixedly formed in the left side of the operation table. According to the garment edge covering machine with the waste collecting function, the guide rail driven by the motor and the auxiliary guide rail are additionally arranged on the side of the workbench, so that the sweeping roller can reciprocate to sweep redundant cloth cut off from the table top and sweep the redundant cloth into the storage groove, meanwhile, a certain table top cleaning effect can be achieved, automatic sweeping and collecting of waste on the table top are achieved, and the working efficiency is improved. Cleaning and recycling are more convenient and efficient.
