preparation example Construction

[0045] The present invention also provides a preparation method of an ecological brick for water purification, wherein the ecological brick is the above-mentioned ecological brick; the preparation method comprises:

[0046] (1) The raw material components are combined to obtain a mixture.

[0047] Preferably, the first premix can be obtained by stirring and mixing oyster shell powder water glass and diatomaceous earth evenly, and the second premix can be obtained by stirring and mixing oyster shell particles, common river sand and water uniformly, and then the first The premix and the second premix are uniformly dispersed in a disperser to obtain a mixture.

[0048] (2) Using a brick press to press the mixture into shaped bricks.

[0049] (3) sintering the shaped bricks.

[0050] Preferably, the sintering treatment temperature is 1000-1200°C, such as 1000°C, 1050°C, 1100°C, 1150°C or 1200°C, etc., and the sintering treatment time is 50-70min, such as 50min, 55min, 60min, 65m...

Embodiment 1

[0055] A preparation method of an ecological brick for water purification is as follows:

[0056] (1) Put the discarded oyster shells into a horse boiler at 700°C for pre-burning for 30 minutes, then a part of them is roughly ground to obtain oyster shell particles with a particle size of about 1.5 to 2.5mm, and a part is put into a ball mill and passed through a 100-mesh sieve after grinding. Get oyster shell powder and set aside.

[0057] (2) Take 20 parts of oyster shell powder prepared in step (1), 15 parts of water glass and 25 parts of diatomaceous earth, stir and mix evenly to obtain a first premix.

[0058] (3) Take 15 parts of oyster shell particles prepared in step (1), 10 parts of common river sand and 10 parts of water, stir and mix evenly to obtain a second premix.

[0059] (4) placing the first premix obtained in step (2) and the second premix obtained in step (3) in a dispersing machine to disperse uniformly to obtain a mixture.

[0060] (5) The mixture of ste...

Abstract

The invention discloses an ecological brick used for purifying water, a preparation method of the ecological brick and a water purification device. The ecological brick comprises the following raw material components, in parts by weight: 20-30 parts of oyster shell powder, 5-15 parts of water glass, 25-35 parts of a binder, 15-20 parts of porous particles, 10-15 parts of natural sand, and 10-15 parts of water. The ecological brick provided by the invention is obtained by mixing raw materials such as the oyster shell powder, the water glass, the porous particles and the natural sand, the prepared ecological brick has good adsorption purification performance on TN, ammonia nitrogen, TP, Cu<2+>, Zn<2+>, Ni<2+>, Mn<7+> and the like in sewage, and the ecological dam formed by stacking the ecological bricks can have good water purification effects on polluted rivers and lakes, and make the water quality in the rivers and the lakes becomes better and better; and the ecological brick has low preparation costs, can be used for a long time, and is in line with a current green development theme.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular, to an ecological brick for water purification, a preparation method thereof, and a water purification device. Background technique [0002] In recent years, with the rapid development of the economy, the problem of water pollution has become more and more serious. Among them, the pollution of rivers and lakes near factories and residential quarters is particularly serious, which seriously affects the quality of the surrounding living environment and people's health. Health, therefore, the treatment of water purification in polluted rivers and lakes etc. is becoming more and more important. [0003] At present, the methods of decontamination and purification of polluted rivers and lakes include: 1. Direct manual salvage of pollutants in rivers and lakes; 2. Purification of rivers and lakes through large-scale mechanized equipment. However, the former requires a lot of manpo...
