Abstract
The invention discloses a treatment method of municipal sludge. The treatment method concretely comprises the following steps: evenly mixing the municipal sludge with an auxiliary material; processing and molding, and then transferring to a sintering apparatus; sintering at 200-2000 DEG C, so as to prepare a ceramic product, wherein the mass percent of the municipal sludge is 20-80%; the mass percent of the auxiliary material is 20-80%; the auxiliary material comprises china clay and an assistant. The treatment method has the beneficial effects that the treatment method is simple in technique and fewer in fixed investments, and is matched with a municipal sewage plant, a factory can be built near the municipal sewage plant, and a production line can also be arranged inside the factory. The treatment method is less in floor area, the pollution problem of the sludge is thoroughly solved, recycling of resources is achieved, the waste is changed in treasure, resources are saved, the environment is protected, and the product is wide in usability and good in economic benefits.
Description
Technical field
The treatment process that the present invention relates to a kind of municipal sludge, belongs to field of environment engineering technology.
Background technology
The mud of municipal sewage plant is that modern city sewage focuses on and carries over an insurmountable significant problem, and governments at all levels and environmental protection relevant departments have all dropped into very large financial resources and material resources, cannot solve all the time the secondary pollution problem that mud exists; Some sludge disposal technology all cannot finally solve in the market---that is to say final or remain with the character of polluting, can only be concentrate, burning form reduces the volume of mud, but do not change contamination level, and suitable power consumption.Another kind of form is domestic sludge and general clay manufacturing bricks by mixing, this viscosity because of domestic sludge is not high, and shipment distance is long, the expense of state subsidies can not be mutually low with transport charge, the needed input of brick field is too high, be that brick field oneself is low with the cost of full vitrified bond on the contrary, and fire product strength, greatly lower, so general brick field is all unwilling with this technology brickmaking.
Summary of the invention
The object of the invention is, in order to make up the deficiencies in the prior art, provides the urban sludge treating method that domestic sludge is converted into ceramic building material or artwork.
A kind for the treatment of process of municipal sludge, specifically: municipal sludge is mixed with auxiliary material, machine-shaping, then move in agglomerating plant, at 200 ~ 2000 ℃, carry out sintering, make ceramic product, wherein, the weight percentage of described municipal sludge is 20 ~ 80%, and the weight percentage of described potter's clay is 20 ~ 80%, and auxiliary material comprises potter's clay and auxiliary agent.
In the present invention, the water ratio of described municipal sludge is 50 ~ 70%.
In the present invention, the mode of described machine-shaping is manual assembly or mould molding.
In the present invention, the temperature of described sintering is 500 ~ 2000 ℃.
In the present invention, described agglomerating plant is high temperature sintering furnace, high temperature sintering furnace or microwave oven.
In the present invention, in described auxiliary material, the weight percentage of potter's clay is 90 ~ 100%, and the weight percentage of auxiliary agent is 0 ~ 10%.
Further, described auxiliary agent is at least one in oxide compound, glass-cermic powder, Zijin soil, clay.
The present invention thoroughly solves the method that sludge from wastewater treatment plant is processed, utilize the physical property of mud, it as starting material, mix with potter's clay (kaolin) etc., according to the different purposes of product, by different ratios, without temperature, make the product of various pottery classes, porcelain class, product can be used in average family and also can be used in various public works.Such as make various crocks, porcelain, ceramic tile etc. be used in the finishing of family and plant flower, plant tree] all kinds of storage tools and view and admire artwork; Can also make the various building materials such as walkway board that engineering uses, brick, various dividing plates.This technological operation is convenient, and method is simple.Can also can produce with factory's pipeline system with family workshop type; and product diversity; the huge market demand; cost of investment is few; and the pollution problem that can thoroughly solve mud; more can reduce kaolinic usage quantity, protection national resources reduces the pollution causing because of exploitation kaolin simultaneously.
