Embodiment 1

[0032] The present embodiment 1 provides a water treatment alloy material formulation, which includes the following elements by weight ratio:

[0033] Zinc: 28%-35%;

[0034] Tin: 4%-7%;

[0035] Nickel: 19%-26%;

[0036] Rare earth: 1.5%-3.5%;

[0037] The balance is copper.

[0038] In the formula of the present invention:

[0039] The effects of its elements on microorganisms are:

[0040] Copper is the most critical element in sterilization materials, which can inhibit the growth of various bacteria, viruses, and microorganisms in water. Copper generates copper ions in the water environment, and copper ions can reach the interior of the cell through the cell membrane, denature some enzymes in the cell, thereby destroying its metabolism and killing microorganisms;

[0041] Zinc and copper elements have a large potential difference, and their alloys can form countless tiny primary batteries in solution. The electrode potential of zinc is low, and it is easy to lose el...

Embodiment 2

[0047] This embodiment is based on Embodiment 1, which is mainly used to inhibit microorganisms in water treatment.

[0048] This embodiment provides alloy sterilization experiment:

[0049] First, the alloy is processed into tubular structures of different diameters;

[0050] Assemble alloy pipes of different diameters in the form of large pipes and small pipes, and set stainless steel pipes on the outermost part of the combined pipe, and weld the inlet flange and outlet flange at the left and right ends of the combined pipe;

[0051] Install the combined pipeline in the water treatment system for treatment.

[0052] Then, the activated yeast liquid is passed through the alloy sterilization equipment at a certain flow rate for several times, and the yeast liquid that has been sterilized by the alloy sterilization equipment for different times is plate-plated and cultured and counted.

[0053] Finally, through the plate counting results, the concentration of viable bacteria ...

Embodiment 3

[0058] This embodiment is based on Embodiment 1, which is mainly used for inactivating microorganisms in water treatment.

[0059] The alloy sterilization equipment is the same as in the above-mentioned single bacteria killing experiment, and the sterilization object is replaced by the activated sludge mixture composed of various microorganisms from yeast. The activated sludge mixture is sterilized for different times by alloy sterilizing equipment. Because there are many kinds of microorganisms in activated sludge, and there are a large number of non-culturable microorganisms, it is not suitable to use the plate counting method. This experiment uses the glucose metabolism rate to evaluate the sterilization effect. Shaking bed culture, before the culture, add a certain amount of glucose to the activated sludge mixture, so that the initial concentration of glucose is 1000mg / l, and then cultivate for 12 hours to detect the residual concentration of glucose in the mixture. The hi...

Abstract

The invention discloses a formula of a multiple oxidation-reduction alloy material with inactivated microorganisms. According to the formula, the multiple oxidation-reduction alloy material is prepared from the following elements in percentage by weight: 28%-35% of zinc; 4%-7% of tin; 19%-26% of nickel; 1.5%-3.5% of rare earth; and the balance of copper. Alloy prepared by the multiple oxidation-reduction alloy material formula has wide adaptability to microbial flora, can selectively and effectively inactivate the microorganisms proliferating in the field of biochemical sewage treatment, realize the in-situ reduction of residual activated sludge, solve the environmental outlet problem of traditional residual activated sludge, and is superior to traditional KDF alloy in terms of machinability and thermoforming.

Description

technical field [0001] The invention relates to water treatment alloy technology, in particular to a multiple redox alloy material formula with inactivated microorganisms. Background technique [0002] The remaining activated sludge treatment technologies produced by conventional biochemical sewage treatment mainly include landfill, composting, making building materials, dry distillation and incineration. Landfill will cause serious pollution to the environment and groundwater. The country has taken measures to limit it. On the one hand, composting has a great impact on the surrounding environment; . At present, the state strongly recommends incineration as the main way to dispose of sludge. High-temperature combustion can completely oxidize organic matter to achieve sludge reduction, and has high stability, but because of its high investment and operating costs, it imposes a heavy financial burden on the government. In-situ sludge reduction technologies proposed in recen...
