Technical Field

[0001] The utility model relates to the technical field of sewage treatment devices, in particular to zero-valent iron sewage treatment equipment. Background Art

[0002] Arsenic is a non-metallic element widely distributed in nature. Long-term drinking of high-arsenic water leads to chronic arsenic poisoning, which is manifested by headaches, dizziness and other symptoms, with skin damage being the most prominent. In order to facilitate the removal of arsenic from sewage, zero-valent iron is used to neutralize and filter the sewage to improve the efficiency of sewage treatment.

[0003] Among the publicly authorized patents, in the Chinese patent with the patent number "CN201720274914.6", a zero-valent iron composite reaction sewage treatment equipment is disclosed, including a shell, in which a water distributor 1, a zero-valent iron layer, a quartz sand layer, a pebble layer and a water distributor 2 are arranged in sequence from top to bottom. The water distributor 1 is arranged at the top of the shell, and the water distributor 2 is located in the pebble layer near the bottom of the shell. A central tube is arranged between the water distributor 1 and the water distributor 2, and the zero-valent iron layer is located in the middle and upper part of the shell. In general, the zero-valent iron composite reaction sewage treatment equipment has a simple structure, is easy to operate, and has a good wastewater purification effect;

[0004] In the above device, a zero-valent iron layer, a quartz layer, etc. are placed in a filter device, and harmful impurities in sewage can be filtered through different filter layers at the same time to improve the filtration efficiency of the sewage treatment equipment. However, in the above device, different levels of filter layers are stacked on each other, and when the filter layers are placed, there are gaps between the filter layers and the inner wall, which will cause the sewage to slide down through the gaps with the inner wall parts, thereby causing the problem of insufficient sewage filtration. For this reason, we propose a zero-valent iron sewage treatment device. Utility Model Content

[0008] Preferably, the filter device is placed on the upper part of the lower support frame, and the limiting plate is placed inside the limiting hole. Four groups of the filter device are installed inside the filter box.

[0009] Preferably, a slide groove is provided on the inner side of the partition plate, and a slide rail is installed on the outside of the liquid transmission box and is movably sleeved inside the slide groove.

[0014] 1. The zero-valent iron sewage treatment equipment is stacked and placed inside the filter box through the filter device. At the same time, a partition plate is installed between the filter device and the liquid transmission box. The partition plate performs sealing and protection treatment between the liquid transmission box and the filter device. At the same time, after the limit plate is installed inside the limit hole, the limit plate limits the position of the two groups of filter devices, and the limit plate performs sealing treatment between the two groups of filter devices. The sealing performance between the two groups of filter devices prevents the liquid from sliding down the chute through the gap between the liquid transmission box and the filter device, thereby improving the sewage treatment efficiency.

At the same time, the preliminary filter box drives the liquid to be transported to the inside of the filter box for separation to the outside, and the diverter plate blocks the internal liquid transported to the inside of the filter box to prevent the liquid from being directly transported to the inside of the liquid transmission box. At the same time, the U-shaped tube and the liquid transmission box are interconnected. Through the position of the installed liquid circulation pipe, the liquid circulation pipe can drive the liquid filtered to different depths in the filter box to be discharged to the outside, thereby improving the efficiency of liquid discharge and increasing the reserved time of liquid in the filter box.
