Embodiment 1

[0025] ①Collect 10kg of waste dry batteries for the production of treatment agents for sewage treatment or water purification, namely T liquid flocculant and N liquid coagulant aid,

[0026] ② Use a special grinder to crush the above-mentioned waste dry batteries,

[0027] ③ Using the screening method, magnetic separation method, water flotation method, and sorting crushed objects, two types are obtained:

[0028] Class I, metal: copper, iron, zinc, nickel, aluminum,

[0029] Class II, non-metal: carbon rod, ammonium chloride, zinc chloride, graphite, acetylene black, paste, paper, plastic, asphalt, manganese dioxide, manganese trioxide,

[0030] Among the second-class non-metallic objects, carbon rods, plastics, asphalt, graphite, and acetylene black, which are not harmful to the environment, are taken out and used separately.

[0031] ④Put manganese dioxide and manganese trioxide into a reaction kettle, add 10 times of water, heat to 200°C, pressurize to 1.5 atmospheres, a...

Abstract

The waste water treating agent includes T flocculant liquid and N coagulant aid liquid. The waste water treating agent is prepared through the process of: crushing and separating waste battery, heating, pressurizing and acid treating MnO2 and MnO3 to produce soluble matter A; heating and pressurizing ammonium chloride, zinc chloride, paste and paper and acid and alkali treatment to produce soluble matter B; heating and pressurizing Cu, Fe, Zn, Ni and Al separately and acid treatment to obtain metal salt C; polymerizing A, B and C inside a polymerizing apparatus through heating, pressurizing and adding catalyst to obtain polymers D1, D2 and D3; mixing D1 and D3 to obtain T flocculant liquid and D2 is the N coagulant aid liquid. The preparation process has no secondary pollution.

Description

technical field [0001] The invention relates to a method for producing sewage treatment agent using waste batteries as raw materials, in particular to a method for producing T liquid flocculant and N liquid coagulant aid for sewage treatment or water purification by using waste batteries as raw materials method. technical background [0002] At present, with the development of my country's economic construction and the improvement of people's living standards, people pay more and more attention to their own environment. In recent years, the problem of environmental pollution by waste dry batteries and the problem of sewage treatment have aroused great concern. Since there are acids, alkaline substances and heavy metals in dry batteries, the leakage of these harmful substances is harmful to human health. Internationally, the harmless treatment of waste dry batteries has adopted steps such as classified treatment, heating and melting, electrolytic sep...
