Embodiment 1

[0015] A method of using sludge is to deodorize the sludge and mix it with bamboo charcoal, sepiolite, foaming agent, potassium feldspar, expanded perlite, calcined kaolin, wollastonite powder, sodium lauryl sulfate Together to make insulation bricks. Among them, the parts by weight of each material are: 80 parts of sludge, 11 parts of bamboo charcoal, 10 parts of sepiolite, 15 parts of foaming agent, 21 parts of potassium feldspar, 8 parts of expanded perlite, 7.5 parts of calcined kaolin, wollastonite powder 4.5 parts, 3 parts of sodium lauryl sulfate.

[0016] The process of the deodorization treatment is: according to the ratio of adding 80 grams of deodorant per ton of sludge, mix and place for 8 days; the deodorant is loaded with denitrification microbial flora and EM flora mixed bacteria Microbial carrier; the microbial carrier is mixed with vermiculite, sawdust and clay according to the weight ratio of 1:4:0.25, and then pressed into granular form after adding binder....

Abstract

The invention belongs to the technical field of urban sewage treatment and particularly relates to a method for utilizing sludge. The method comprises: deodorizing sludge, and making it with bamboo charcoal, sepiolite, a foaming agent, potassium feldspar, expanded perlite, calcined kaolin, wollastonite powder and sodium dodecyl sulfate to obtain an insulation brick. The use of the method provides sludge resourceful utilization turning waste into wealth, and also provides new economic benefit, reducing economic burden for sludge treatment.

Description

technical field [0001] The invention relates to the technical field of urban sewage treatment, and relates to a method for utilizing sludge. Background technique [0002] Sludge is the product of sewage treatment, which is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. The main characteristics of sludge are high water content, high organic content, easy to rot and smell, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. With the acceleration of urbanization in my country, the discharge of urban sewage continues to increase, and the amount of sludge, especially the excess sludge, produced by sewage treatment plants is increasing. Generally, sludge treatment and disposal costs account for more than 50% of the total operating costs of sewage treatment plants, requiring huge capital investment. Therefore, if the resource utilization of sludge can be real...
