Embodiment 1

[0013] The preparation process of the granular spontaneous micro-battery sewage treatment agent of the present invention is shown in the accompanying drawings, with gas ash and recycled iron powder as the main raw materials, biomass and ordinary clay as auxiliary materials, and prepared by sintering method, the specific steps are as follows:

[0014] (1) Sieve the dust generated in the blast furnace ironmaking dust removal process to less than 100 mesh (average particle size ≤ 0.154mm) to make gas ash; crush the scrap iron slag in the blast furnace ironmaking process through a ball mill and sieve it to 100 mesh Make recycled iron powder as follows; crush biomass (any crop straw, aquatic plant straw or sawdust) and sieve it to below 100 mesh; crush and sieve clay to below 100 mesh;

[0015] (2) Mix the gas ash, reclaimed iron powder, biomass and common clay prepared in step (1) evenly according to the ratio of 35:38:11:16 in mass ratio, and put the mixed powder in a disc-type ba...

Embodiment 2

[0018] The difference between this example and example 1 is that the mass ratio of gas ash, reclaimed iron powder, biomass and common clay is 45:33:9:13, and the average particle diameter of the raw meal balls made is 5.5 mm. The pellets are sintered at a temperature of 1180° C. for 50 minutes in a high-temperature sintering furnace.

Embodiment 3

[0020] The difference between this example and example 1 is that the mass ratio of gas ash, recycled iron powder, biomass and common clay is 55:28:7:10, and the average particle size of the raw meal balls made is 6mm. The balls are sintered at 1200°C for 45 minutes in a high-temperature sintering furnace.

[0021] The granular spontaneous micro-battery sewage treatment agent fired by the sintering method in the above embodiments can be used for the treatment of heavily polluted textile industry wastewater, the advanced treatment of heavy printing and dyeing wastewater, and the removal of cyanide and Cr from electroplating wastewater. 6+ detoxification treatment, sterilization treatment of hospital wastewater, etc.

Abstract

The invention provides a granular spontaneous micro battery sewage treatment agent which comprises gas ashes, a recycling iron powder, biomass and ordinary clay in the mass ratio of 35-55:28-38:7-11:10-16. A preparation method of the granular spontaneous micro batery sewage treatment agent comprises the following steps of uniformly mixing the gas ashes, the recycling iron powder, the biomass and the ordinary clay in the mass ratio of 35-55:28-38:7-11:10-16; rolling a mixed powder in a disk type ball maker to make balls; arranging the balls in a high-temperature sintering furnace with the reduction atmosphere to sinter for 45-60min at the temperature of 1120-1200 DEG C; and cooling to the room temperature. The invention has simple preparation technology and uses industrial wastes and plant straws, thereby being environment friendly and energy saving. The prepared sewage treatment agent utilizes the power spontaneously generated by a micro battery to break down pollutants which are difficult to degrade in water.

Description

technical field [0001] The invention relates to a sewage treatment agent and a preparation method thereof, belonging to the technical field of sewage treatment. Background technique [0002] With the deepening of industrialization, the discharge of industrial wastewater is gradually increasing, and industrial wastewater is becoming more and more difficult to degrade and treat. Take printing and dyeing industry wastewater as an example: printing and dyeing wastewater is one of the main harmful and difficult-to-treat industrial wastewater in China, mainly including dye organics with chromophoric groups and printing and dyeing auxiliaries. It is characterized by a large amount of wastewater, complex water quality, high concentration of organic matter, many refractory biodegradable substances, and deep color. Among them, the pollution of dyes is the most serious. Even if the concentration of the remaining dye components is very low, the light transmittance of the water body wil...
