Problems solved by technology

Furthermore, the overlap of the fillers results in small surface voids, and the dirt is not easy to be effectively cleaned, and the dirt inside the filler layer is difficult to discharge, which will reduce the activity of the filler and block the electrolytic mass transfer between the filler and the treated water.
The increase in the bulk density of iron fillers will also increase the investment of fillers, but the treatment effect has not been increased.

Embodiment 1

[0012] Example 1: see figure 1 , an inner electrolytic iron bed water treatment device, including an outer cylinder 1, an axially built-in inner circulation cylinder 9, a filler shelf 4 and an aeration tube 5 at the bottom of the interlayer of the inner and outer cylinders, and a built-in three-dimensional polyhedral iron filler 3 ( Figure 3-10 ), there is an aeration pipe 10 at the lower bottom of the inner circulation cylinder, a balanced triangular guide ring 8 on the inner side of the upper end, a defoaming ring groove 7 on the upper inner side of the top of the cylinder body, a conical mud collecting bucket 11 at the lower bottom, and the water inlet pipe 6 is located at In the lower part of the cylinder, the outlet pipe 2 is below the defoaming ring groove.

Embodiment 2

[0013] Example 2: see figure 2 , as mentioned above, increase the central cylinder 9, place the iron filler 3 in the central cylinder, and the outlet of the central cylinder has a balanced diversion bell mouth 8. The iron filler preferably adopts a cross structure.

Abstract

An improved internal electrolytic iron bed as water treating apparatus is composed of a water-treating cylinder, an axially arranged internal short cylinder, silt collecting hopper under said water-treating cylinder, the cubic iron filler between said internal and external cylinders or in internal one, and air distributor under the space between said internal and external cylinders. Its advantages are high activity, large mass transfer area and high treating effect.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to the improvement of the inner electrolytic bed water treatment device and iron filler. Background technique [0002] Chinese patent 98242534 discloses a continuous high-activity iron bed water treatment device. In order to ensure the high activity of the iron filler, the treated water is returned through extracorporeal circulation at high speed, and the surface of the iron filler is washed at a high flow rate. The hydrogen bubbles accumulated on the surface and the deposited dirt are washed and discharged to maintain the high activity of the iron filler and improve the mass transfer of the filler. This method of cleaning the filler by increasing the flow rate through the external circulation of the filtrate has a strong cleaning effect on the surface of the filler, but this cleaning method of bottom flushing and floating may easily cause the separation of the three phases (steam, ...
