Problems solved by technology

The massive discharge of domestic sewage and industrial wastewater will inevitably accumulate a large amount of biochemical sludge, which not only takes up space, but also its harmful components and organic sludge have become a major public hazard for urban sanitation, while waste oil (especially waste oil) ) will also be sold by some criminals as cooking oil and put on people's tables, seriously endangering people's health

Embodiment 1

[0028] Preparation of 1000kg material environmental protection brick

[0029] According to the proportion of the above-mentioned environmentally friendly bricks, weigh 300kg of biochemical sludge and 700kg of laterite, mix and stir the above-mentioned raw materials with appropriate amount of water, and make a plastic mixed mud, which is pressed in a brick press to form an environmentally friendly brick. The kiln is fired to obtain the finished environmental protection brick. The preparation of the environmental protection brick includes the following steps:

[0030] 1) Preparation of environmentally friendly brick mixture

[0031] According to the proportion of the above-mentioned environmentally friendly brick components, weigh the raw materials of each component, stir and mix them in the mixer, and prepare the environmentally friendly brick mixed mud with uniform particle size distribution and plasticity;

[0032] 2) Preparation of adobe

[0033] Push the mixed brick mud m...

Embodiment 2

[0038] Preparation of 1000kg material environmental protection brick

[0039] According to the above-mentioned ratio of environmentally friendly bricks, weigh 400kg of biochemical sludge and 600kg of laterite, mix and stir the above raw materials with appropriate amount of water, and make a plastic mixed mud, which is pressed in a brick press to obtain environmentally friendly bricks. After the bricks are dry, put them into Kiln firing makes the finished product of environmental protection brick, and the sintering temperature of environmental protection brick is 950 ℃, and its preparation process is with reference to embodiment 1.

Embodiment 3

[0041] Preparation of 1000kg material environmental protection brick

[0042] Weigh 500kg of biochemical sludge and 500kg of laterite according to the ratio (the moisture content of biochemical sludge is 30-80%), mix and stir the above raw materials with appropriate amount of water to make a plastic mixed sludge, which is produced in a brick press. The adobe is fired in a kiln after the adobe is dried. The sintering temperature of the environmental protection brick is 850°C, and then the environmental protection brick products are fired. Its preparation process refers to embodiment 1.

Abstract

The invention relates to a method for preparing environment-friendly bricks by using a mixture of biochemical sludge and red clay and by using waste oil as a fuel. According to the invention, biochemical sludge produced during urban sewage treatment process is mixed and stirred with red clay and coal cinder powder according to a certain ratio, such that a plastic mixed brick pug is prepared; the pug is pressed in a brick press, such that environment-friendly brick blanks are prepared; the brick blanks are dried, and are fired in a kiln, such that the environment-friendly brick products are obtained. During firing, a firing heat source of high-temperature flue gas produced by combustion of a fuel of waste oil is delivered into the brick kiln through a pipe. According to the invention, the environment-friendly bricks are fired by using a mixture of biochemical sludge and red clay and by using waste oil as the fuel, such that wastes are turned into valuable matters, and energy is saved. The red clay is widely distributed, such that the material is easy to obtain and is cheap. Also, no farmland is occupied. The method has good social and economical benefits.

Description

technical field [0001] The invention relates to an environmental protection treatment technology of biochemical sludge, in particular to an environmental protection brick manufactured by mixing biochemical sludge and laterite for waste oil as fuel and a preparation method thereof, belonging to the technical field of environmental protection treatment. Background technique [0002] With the development of industrialization and the acceleration of urbanization, more and more industrial and domestic wastes are produced, especially the industrial and domestic wastes produced in cities, which are generated much faster than they are processed. Large and medium-sized cities The predicament of garbage siege has occurred, which has greatly threatened and seriously affected the lives of residents. Among the above types of garbage, the biochemical sludge produced in the sewage treatment process and the waste oil (such as gutter oil) in the kitchen waste need further environmental prote...
