Embodiment 1

[0049] Formulation (with mass parts):

[0050]

[0051] According to the above formulation ratio, liquid water glass, 50% liquid base (aqueous solution of aqueous sodium hydroxide), sodium hydroxide, sodium hydroxide, and water were mixed with water at 150 r / min, and then slowly The -OH carboxylic acid polymer was added, and the mixture was allowed for 10 min to uniform at a speed of 150 r / min while adding, and then slowly added sodium pentewater-biased silicate, and the mixture was mechanically stirred at a speed of 150 r / min while adding 10 min to uniform. To produce desulfurization wastewater extracts.

[0052] Take 200g Yingcai Soil BC01, add 0.6% of the desulfurization wastewater gel, 12.8 g of desulfurization wastewater and 115.1 g of water, i.e., a water moratorium, and produce a uniform mud in the planetary ball mill. Then, the mud viscosity was measured, and the initial viscosity of the mud was 37.6 s; after standing for 5 min, the viscosity was measured, the slur...

[0054] Formulation (with mass parts):

[0055]

[0056] According to the above formulation ratio, the liquid water glass, 50% liquid base, sodium tripolyphosphate and water were first mixed, and the mixture was stirred at 150 r / min to uniform; then the S-carboxylic acid polymer was slowly added, and when added The mixture is mechanically stirred at 150 r / min to uniform; finally sodium hexaphosphate is slowly added, and the mixture is mechanically stirred at 150 r / min at a speed of 10 min to uniform, and the desulfurization wastewater extract is obtained.

[0057] Take 200g Yingcai Soil BC01, add 0.5% of the desulfurization wastewater extractant, 12.8 g of desulfurization wastewater and 115.1 g of water, i.e., a water grinding, and a uniform mud. Then the mud was coated with a -4 cup to measure the slurry viscosity, the initial viscosity of the mud was 47.5 s; after standing for 5 min, the viscosity was measured, the slurry viscosity was 87.4, and the thixotropy index was 1...

Embodiment 3

[0059] Formulation (with mass parts):

[0060]

[0061] According to the above formulation ratio, liquid water glass, 30% liquid base, pyrophosphate and water are mixed, and the mix is ​​mechanically stirred; then the S carboxylic acid polymer is slowly added, and the side is added while adding; The mixture is mechanically stirred at 150 r / min to uniform, and the desulfurization wastewater extract is obtained while adding.

[0062] Take 200g Yingcai Soil BC01, add 0.5% of the desulfurization wastewater extractant, 12.8 g of desulfurization wastewater and 115.1 g of water, i.e., a water grinding, and a uniform mud. Then the mud was applied to the -4 cup to measure the viscosity of the mud, and the initial viscosity of the mud was 48.8 s; after standing for 5 min, the viscosity was measured, the slurry viscosity was 87.5s, and the thixotropy index was 1.793.

Abstract

The invention discloses a gelling agent for desulfurization waste water, a preparation method and application thereof. The desulfurization waste degelling agent of the present invention comprises the following components in parts by mass: 30-60 parts of carboxylic acid polymer, 20-45 parts of liquid water glass, 6-18 parts of regulator, 1-5 parts of liquid alkali, 1 to 10 parts of water. The desulfurization waste degelling agent of the present invention is prepared by the following method: mix liquid water glass, liquid caustic soda, part of the regulator and water, and stir evenly; Evenly, the desulfurization waste water hydrolysis agent is prepared. The desulfurization waste water gelling agent of the invention has wide sources of raw materials, low price and environmental protection, and can be used to recycle desulfurization waste water to prepare mud with good viscosity and thixotropy. The invention overcomes the failure problem of conventional debonding agents in desulfurization wastewater, can effectively treat desulfurization wastewater, has good economic and environmental benefits, and has good application prospects.

Description

Technical field [0001] The present invention belongs to the ceramic industry, and the fine chemical technology is related to a desulfurization wastewater neoplastic and the preparation method thereof. Background technique [0002] The desulfurization wastewater contains suspended substances, supersaturated sulfite, sulfate, and heavy metals, many of whom are the first type of pollutant that requires strict control in national environmental standards. The composition of desulfurization wastewater is complex, the treatment is difficult, and the equipment, treatment agent, energy, etc. are required, and the occupancy is large, the processing is long, and the comprehensive cost is high. Common desulfurization wastewater treatment techniques include settling pool, chemical settlement, biological treatment, zero emission technology (evaporation cell, complete cycle, mixture with fly ash, etc.). Among them, the settlement pool treatment cost is low, and the particulate matter can be rem...
