Description

Copper-containing sewage treatment equipment Technical Field The invention relates to the technical field of sewage treatment, in particular to copper-containing sewage treatment equipment. Background Copper-containing wastewater is common in electroplating, metal surface treatment, circuit board processing and related industrial production processes. In order to reduce the content of copper ions in wastewater, the existing treatment process generally adopts a mode of chemical precipitation and combining coagulation, flocculation and sedimentation separation, so that the copper ions in the wastewater form precipitates, and solid-liquid separation is realized in a sedimentation tank. After sedimentation, the upper part is a relatively clear liquid phase, and the lower part forms copper-containing sludge. Copper-containing sludge usually contains more water, has certain fluidity and adhesiveness, and is not conducive to subsequent collection, temporary storage and outward transportation without further dehydration, and the treatment cost and the field management difficulty are increased. Therefore, after the precipitation separation is completed, the sludge at the bottom of the tank is usually required to be subjected to compression dehydration treatment so as to reduce the water content and the volume of the sludge and facilitate the subsequent treatment. In the prior art, a sedimentation tank is generally only used for completing sludge sedimentation, after a certain accumulation amount of sludge at the bottom of the tank is reached, the sludge is conveyed to filter pressing equipment which is independently arranged outside the tank for dehydration in a suction, pumping or mechanical transferring mode, and the sludge cake is discharged and cleaned after the sludge cake is formed. That is, the sedimentation, collection, dehydration and discharge of the sludge are usually completed by different devices, and the related processes are connected by intermediate transfer. Although the treatment mode can finish sludge dewatering, certain defects still exist in the actual use process. On the one hand, when sludge is transferred to external dehydration equipment from a sedimentation tank, a sludge pump, a conveying pipeline or other transfer devices are generally required to be configured, equipment components are scattered, a treatment link is long, the occupied area is large, the integrated arrangement of the equipment is not facilitated, and the equipment investment and maintenance cost are increased. On the other hand, in the process of extracting, conveying and transferring copper-containing sludge, dripping, scattering or attaching residues are easy to occur, copper-containing liquid entrained in the sludge has the risk of leakage, and the field pollution control difficulty is easy to increase. In addition, in the prior art, the sedimentation process in the pond and the dehydration process outside the pond are mutually separated, and after the sedimentation of the sludge at the bottom of the pond is completed, the sludge still needs to be collected again, conveyed again and filtered again, so that the process connection is poor, and the overall treatment efficiency is limited. Especially in the taking out and unloading link after the mud cake is formed, the manual auxiliary or additional unloading structure is generally needed, the continuous operation capability is weaker, and the automation degree and the stability of the copper-containing sludge treatment process are not improved. Therefore, it is still necessary in the prior art to provide a device suitable for copper-containing sludge treatment, so as to further realize centralized treatment of sludge on the basis of related operations of a sedimentation tank, shorten the treatment flow, reduce intermediate transfer links, reduce the leakage risk of sludge and filtrate, and improve the overall efficiency of sludge dewatering and unloading operations. Disclosure of Invention The present invention aims to solve at least one of the technical problems existing in the prior art or related art. Therefore, the invention aims to provide copper-containing sewage treatment equipment, which comprises a sedimentation tank, a mud pressing mechanism positioned in the sedimentation tank, and a first beam and a second beam which are arranged on the side wall of the sedimentation tank in a crisscross manner, The mud pressing mechanism comprises a mud pressing cylinder and a mud pressing drainage component positioned in the mud pressing cylinder, The mud pressing cylinder is arranged on a second beam, a mud discharging component is arranged on the second beam, A mud pressing groove is arranged at the center of the bottom of the sedimentation tank right below the bottom of the mud pressing cylinder, The mud pressing and draining assembly comprises a mud pressing plate and a fixed cover which are movably arranged, the top surface of the fixed cover is provided with a water c
