Embodiment Construction

[0013] The technical solution of the present invention will be further described in detail below in conjunction with specific embodiments.

[0014] The preparation method of polysilicon titanium salt coagulant: under the conditions of stirring and ice-water bath, take 20.00g of pure titanium tetrachloride solution and add it dropwise to 100ml of ice water to obtain a mass-volume ratio of 20% (200g / L). Titanium tetrachloride solution, and then under high-speed magnetic stirring, a certain amount of 20% NaOH solution was added dropwise to prepare polymerized titanium chloride solutions with different degrees of alkalization B (the molar ratio of OH to Ti), Aging 24h. Synthesize PTSC by copolymerization, and the preparation method is as follows: use fresh polysilicic acid, mix it with titanium tetrachloride according to the predetermined silicon-titanium molar ratio, add a predetermined dose of sodium hydroxide, mix and stir for 2 hours, and obtain different silicon-titanium mola...

Abstract

The invention provides a preparation method and application of a polysilicate-titanium coagulant. Titanium is safe and non-toxic to human bodies, and the removal effect of water treatment adopting a titanium salt compound as the coagulant is obviously higher than that of a traditional aluminum salt and iron salt flocculant.

Description

technical field [0001] The invention relates to a coagulant, in particular to a preparation method and application of a polysilicon titanium salt coagulant. Background technique [0002] With the rapid development of the economy, people's living standards are gradually improving, and residents' drinking water quality standards are also gradually improving, requiring more effective and advanced water treatment processes. With the continuous improvement of water quality standards by the International Water Association, my country has also increased the original sanitary standards for drinking water from 35 to 106. Among them, low temperature and low turbidity water has always been one of the problems in many urban water treatment due to its characteristics of low oxygen consumption, high viscosity, and low alkalinity. The existing water treatment process of water supply enterprises is difficult to achieve good water purification effect for the characteristics of low turbidity...
