Problems solved by technology

[0004] At present, there are many types of permeable materials on the market, the most commonly used are concrete permeable materials, polymer permeable materials, etc., but the preparation costs of these types of permeable materials are relatively high, and many researchers have carried out a lot of research on the preparation of environmentally friendly permeable materials. There are literature reports that solid waste such as fly ash, waste ceramics, and waste glass can be used to prepare environmentally friendly permeable materials with good water permeability and high strength.

Embodiment 1

[0021] a. Raw material preparation: After dehydration treatment of urban sludge and sugar filter mud, drying and drying to make the relative moisture content ≤ 13%; after crushing fly ash, take 160-mesh sieve for feeding, and sugar filter mud, water koji Willow clay is ground by a ball mill and passed through a 100-mesh sieve, and the sieve material is taken; the particle size of the municipal sludge is controlled to 20-40 mesh after crushing, and the waste ceramics are crushed and passed through a 20-mesh sieve; waste glass is crushed and ground into glass powder Pass through 160 mesh sieve;

[0022] b. Billet: according to the mass percentage of permeable material formula: 14% for sugar filter mud, 4% for municipal sludge, 20% for fly ash, 35% for clay, 23% for waste ceramics, and 4% for glass powder Weigh the prepared various raw materials and mix them to form a batch and add water, wherein the amount of water added is 10% of the absolute dry mass of the batch. After mixing...

Embodiment 2

[0027] According to the mass percentage of the permeable material formula in the billet making step: sugar filter mud is 15%, municipal sludge is 5%, fly ash is 20%, clay is 38%, waste ceramics is 17%, and glass powder is 5%. Get the prepared various raw materials and mix to form the batch and add water, wherein the amount of water added is 11% of the absolute dry mass of the batch,

[0028] All the other processing steps are identical with embodiment 1.

Embodiment 3

[0030] According to the mass percentage of the permeable material formula in the billet making step: sugar filter mud is 15%, municipal sludge is 6%, fly ash is 23%, clay is 36%, waste ceramics is 15%, and glass powder is 5%. Mix the prepared raw materials to form a batch and add water, wherein the amount of water added is 12% of the absolute dry mass of the batch. After mixing, stir for 3 hours, granulate it, and stale for 24 hours; Molding, the molding pressure is 15 MPa; then, put it into a drying oven for drying, the drying temperature is 105°C, and the drying time is 6 hours to obtain a dry billet.

[0031] All the other processing steps are identical with embodiment 1.

Abstract

Provided is a method for preparing a seepy material by using city sludge and sugar filter mud. The city sludge and the sugar filter mud are used as a low temperature pore-forming agent and a high temperature pore-forming agent respectively. Industrial waste residue coal ash serves as a raw material, shuiquliu clay serves as binder, waste ceramics serves as aggregate, and glass powder serves as a fluxing agent. A technology process includes drying the raw material, smashing, screening, weighing according to formula requirements, adding an appropriate amount of water, mixing, stirring, prilling, ageing, molding, drying and sintering to obtain products. By means of the method, the seepy material has good seepy performance, can be widely applied to aspects of city construction and separation engineering, such as drainage systems on road surfaces of city, and can achieve effects of beautifying the city and reducing tropical island effect of the city.

Description

technical field [0001] The invention relates to a method for preparing a controllable-scale water-permeable material by using urban sludge and sugar filter mud as pore-forming agents, relates to the field of sewage treatment, and belongs to the field of resources and environment. Background technique [0002] According to the statistics of the national environmental protection department, by 2010, the urban sewage treatment rate in my country will reach 60%. At present, the secondary pollution of sludge has become an environmental problem to be solved urgently. Therefore, the resource utilization of municipal sludge has great development space in our country. [0003] The sugar filter mud used in the present invention is the waste produced during sugar beet sugar production—sugar filter mud. In the process of sugar making, the ratio of sugar output to filter mud (water content 65%) is about 10:3, and the main component of sugar filter mud is CaCO 3 , and its content reache...
