Description

YT-1 type water clearing agent

Technical Field

The invention relates to the field of sewage treatment, in particular to a YT-1 type water cleaning agent.

Background

The existing electroplating production process needs a plurality of water washing with various procedures, and according to the chemical mechanism analysis of hydrochloric acid, the condensation chemical action is mainly generated between hydrogen chloride (including chloride ions) in a hydrochloric acid solution and impurities contained in washing water (tap water): when the plated part is taken out from the acid solution after acid cleaning, a large amount of acid solution is remained on the surface and enters the cleaning water, and the cleaning water turns yellow and turbid immediately under the condensation action of hydrogen chloride (or other acid ions) to become wastewater. This is why electroplating production consumes a large amount of water. The wastewater is rich in various dissolved organic matters, chloride ions and heavy metal substances, and is discharged into a water body without treatment, so that aquatic organisms in the water body are poisoned and suffocated to die, and the water environment is damaged. Various places band the electroplating production and processing, and the problem of wastewater pollution is solved by a 'blocking' method. This undoubtedly kills the industry, cuts the financial path of electroplating manufacturers, and causes strong resistance of enterprise owners and enterprise employees; on one hand, each part of government organization forces at all levels bans electroplating production factories everywhere, on the other hand, enterprise owners adopt wandering combat tactics to carry out production in thousands of parts, enterprise workers interfere with governments to influence income of the enterprises, residents complain that government measures are not enough to pollute water bodies, damage the environment, cause nervousness of trunk group relations, aggravate social contradictions and seriously influence the construction of harmonious society. Therefore, the electroplating production wastewater treating agent and the wastewater treating method which are efficient and cheap are provided, the condensation chemical reaction of cleaning water impurities is prevented, and the electroplating production wastewater treating agent and the wastewater treating method have important practical significance for reducing wastewater discharge, saving water and fundamentally eliminating the problem of wastewater pollution.

Disclosure of Invention

The invention aims to provide a YT-1 type water clearing agent to solve the problems in the background technology; the method has the advantages of mild operation conditions, obvious decolorization effect, small using amount and short consumed time, and can be used as a primary material for the technical transformation of an electroplating process.

The technical scheme adopted by the invention is as follows:

the YT-1 type water clearing agent comprises the following raw materials in parts by weight:

0.2-10 parts of sodium pyrophosphate, 0.2-10 parts of orthophosphate, 0.1-10 parts of metaphosphate, 0.1-10 parts of monocalcium phosphate, 0.1-10 parts of hydrogen peroxide, 0.1-10 parts of washing powder, 0.01-0.2 part of phosphoric acid and 45-90 parts of water; mixing the above raw materials at room temperature to obtain YT-1 type water clearing agent.

The metaphosphate is disodium hydrogen phosphate.

The orthophosphate is trisodium phosphate.

Compared with the prior art, the invention has the beneficial effects that:

after the invention is applied to the technical improvement of the electroplating process, the cleaning procedure is shortened from 12-15 times of the prior electroplating production to 2-3 times. The existing electroplating production process needs a plurality of water washing with various procedures, and according to the chemical mechanism analysis of hydrochloric acid, the condensation chemical action is mainly generated between hydrogen chloride (including chloride ions) in a hydrochloric acid solution and impurities contained in washing water (tap water): when the plated part is taken out from the acid solution after acid cleaning, a large amount of acid solution is remained on the surface and enters the cleaning water, and the cleaning water turns yellow and turbid immediately under the condensation action of hydrogen chloride (or other acid ions) to become wastewater. This is why electroplating production consumes a large amount of water. The invention utilizes the monocalcium phosphate to prevent acid ions in the wastewater to be treated from undergoing a condensation chemical reaction with cleaning water impurities; the process flow is simplified, the production procedure is shortened, and the discharge of waste water and toxic and harmful substances is reduced;

the invention is edible slightly alkaline aqueous liquid, non-toxic and tasteless, is dissolved in water, the using amount is 5-8 per mill of cleaning water (weight ratio), and is directly put into use at normal temperature. The use of the invention can completely inhibit the condensation chemical reaction of hydrogen chloride (including acid ions) and impurities of the cleaning water, promote the impurities of the cleaning water to be filtered by the process self-circulation device, keep the cleaning water clean and transparent, achieve the purpose of long-time use, and reduce the water consumption and discharge amount of the cleaning process.

a. YT-1 type water cleaning agent is added into the wastewater to be treated according to 5-8 per mill, so that the condensation chemical reaction between acid ions brought by the process and impurities of the wastewater to be treated is avoided, the wastewater to be treated is always kept at a certain cleanliness, the cleaned water body is prevented from becoming yellow and turbid in a short time, the service cycle of the water body is prolonged, and the water consumption of the cleaning process is reduced;

b. performing sequencing self-circulation filtration countercurrent treatment; the sorting is that different chemical components of the waste water are generated according to various working procedures, and self-circulation filtration and storage are respectively carried out, so that the old mode of mixed discharge of the existing waste water is broken; thus, the chemical components in the wastewater are the same as those of the chemical solution prepared in the production process, toxic and harmful impurities in the wastewater are removed, the wastewater is resourced again, and the wastewater is used as a carrier for preparing the chemical solution with the same components, so that the aim of reducing or not discharging is fulfilled.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
