AI Technical Summary

Problems solved by technology

[0004] 1) In the wastewater treatment process, the reaction rate is slow and it is easy to passivate and harden after long-term use;
[0005] 2) The price of iron-carbon filler is relatively high, and the construction investment is relatively high;
[0006] 3) Frequent replacement of fillers in practical applications increases operating costs and restricts the promotion and application of micro-electrolysis technology

Embodiment 1

[0033] As shown in the figure, a device that uses iron shavings for upgrading and transforming rural domestic sewage to strengthen phosphorus removal includes an iron shaving filler reaction functional area 1, and a cover plate 1a is provided on the iron shaving filler reaction functional area 1. The iron shavings The shaving filler reaction functional area 1 is provided with a number of independent functional units 2 arranged in a straight line. Two adjacent functional units 2 are connected to each other and each functional unit 2 is filled with iron shaving filler 3, which is located in the iron shaving filler reaction area. The iron shaving filler 3 in a functional unit 2 at one end of the functional area 1 is connected to the water inlet pipe 4, and the other end of the iron shaving filler reaction functional area 1 is provided with a mud collection area 5, which is recessed at the bottom of the iron shaving filler reaction functional area 1 An aeration system 6 is also pro...

Embodiment 2

[0043] The structure and working principle of this embodiment are basically the same as that of Embodiment 1, the difference is that, as image 3 As shown, the iron shaving filler reaction function zone 1 includes a reaction zone 13 and a precipitation zone 14 isolated from each other by a partition wall, and the reaction zone 13 and the precipitation zone 14 form independent spaces, and the iron shaving filler 3 is located in the reaction zone 13 The mud collection area 5 is located at the end of the sedimentation area 14 away from the water inlet pipe 4, a functional unit 2 farthest from the water inlet pipe 4 is connected to the mud collection area 5, and the end of the sedimentation area 14 away from the mud collection area 5 is provided with a water outlet 7.

[0044] combine Figure 4 and Figure 5As shown, the functional unit 2 connected to the mud collection area 5 is provided with a water distribution wall 15, and the water distribution wall 15 is provided with some ...

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a device for improving, transforming and intensifying phosphorus removal of rural domestic sewage by using iron shavings. The device comprises an iron shavings filler reaction functional area, the iron shavings filler reaction functional area is provided with a plurality of functional units which are independent from one another and are arranged along a straight line, every two adjacent functional units communicate with each other, each functional unit is filled with iron shaving filler, the iron shaving filler in one functional unit located at one end of the iron shaving filler reaction functional area is connected with a water inlet pipe, the other end of the iron shaving filler reaction functional area is provided with a sludge collection area, the sludge collection area is sunken in the bottom of the iron shaving filler reaction functional area, an aeration system is further arranged in the iron shaving filler reaction functional area and connected with each iron shaving filler, and a water outlet is formed in the side wall of the iron shaving filler reaction functional area. According to the invention, the construction cost is greatly reduced, and great demonstration significance is brought to improvement and reconstruction of agricultural pollution.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a device that uses iron shavings for upgrading and reforming rural domestic sewage to strengthen dephosphorization. Background technique [0002] The characteristics of rural domestic sewage treatment in my country are: low organic matter load, high nitrogen and phosphorus concentrations, large coefficient of variation in influent water quality and water volume, many terminal points, scattered, limited operation and maintenance forces, and technology. [0003] Iron-carbon micro-electrolytic fillers are widely used in the removal of phosphorus, COD, heavy metals and other pollutants in industrial wastewater. At present, the main commercial fillers are generally prepared by physical mixing of iron-based materials (iron filings or iron powder) and solid carbon-based materials (charcoal powder, coal, activated carbon, etc.) through landfill or roasting molding (regularization)...
