The system comprises two cutting units, two carrying-stacking robots, four material feeding positions, four sheet material discharging positions and a waste material conveying system. Each cutting unit comprises a first mobile quick table, a second mobile quick table and two laser cutting heads, and the first mobile quick table and the second mobile quick table are parallelly arranged. Each mobile quick table is provided with one cutting position and two material receiving positions 1# and 2#. The carrying-stacking robots are respectively arranged on two sides of the cutting units, and external shafts of the robots are perpendicular to the mobile quick tables. The material feeding positions are arranged on the outer sides of the outside of the carrying-stacking robots and provided with material trolleys and corresponding guide rails, wherein the guide rails are parallel to the external shafts of the robots. The waste material conveying system is arranged under the cutting positions of the cutting units. The system can simultaneously achieve steel plate feeding and discharging operation, effectively improve the operation speed and the yield and can meet the small-scale production requirement.

The invention belongs to the technical field of sewage treatment, and relates to a silicon industrial park wastewater treatment process and device. For silicon industrial parks in the prior art, the mixed treatment of white carbon black wastewater and comprehensive wastewater in the park has high levels of salt and difficult biochemistry, and when the two types of wastewater are treated separately, ammonia nitrogen and total nitrogen in the comprehensive wastewater of the park are high, and the carbon-nitrogen ratio is low , the treatment effect of the traditional denitrification process is not ideal, and it is necessary to add a large amount of carbon source to the technical problem. This scheme provides a silicon industrial park wastewater treatment process. By taking out a small part of the wastewater bypass branch in the white carbon black wastewater, the sulfate in the white carbon black wastewater is converted into reduced sulfur, which is a sulfur autotrophic denitrification bacteria. The group provides a sulfur source, and realizes the removal of nitrogen pollution from wastewater with a low carbon-to-nitrogen ratio under the condition of no carbon source addition. This solution also provides a dissimilation / denitrification device, which can realize sulfur conversion and sulfur autotrophic denitrification reaction in the same device, and realize efficient treatment of two different types of wastewater, with compact rhythm, no transfer process, and efficient reaction .
