Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0025] see figure 1 , an embodiment provided by the invention: a method for comprehensive treatment of sludge, comprising the steps of:

[0026] Step A: Carry out garbage sorting in the city to form sludge, and preliminarily solidify the sludge to reduce fluidity, and transport and place the sludge;

[0027] Step B: Dilute and stir the initially solidified sludge, add modified liquid at the same time, kill and disinfect the sludge, and then further add diluted liquid for multi-stage filtration and separation, and separate the residue through multi-stage separation and separation. Precipitation to form liquid fertilizer and degradable impurities;

[0028] Step C: Th...

Abstract

The invention discloses a comprehensive sludge treatment method, relates to the technical field of comprehensive sludge treatment, and solves the problems that an existing comprehensive sludge treatment method is not high in sludge harmless treatment and treatment efficiency, low in conversion rate of treated products and the like. A comprehensive sludge treatment method comprises the following steps: A, garbage classification is conducted in cities to form sludge, the sludge is preliminarily solidified to reduce fluidity, and the sludge is transported and placed; and B, the preliminarily cured sludge is diluted and stirred, a modification liquid is added to sterilize and disinfect the sludge, a diluent is further added to carry out multi-stage filtration and separation, and multi-stage separation and precipitation are carried out on the separated residues to form a liquid fertilizer and degradable impurities. Impurities which cannot be degraded in sludge can be effectively reduced, high efficiency of follow-up treatment and cleanness of products are guaranteed, the product conversion rate of sludge treatment is increased, and harmless treatment of the whole sludge can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of sludge comprehensive treatment, in particular to a sludge comprehensive treatment method. Background technique [0002] With the rapid development of social economy, more and more sludge is produced in the process of people's life and production. Through concentration, conditioning, dehydration, stabilization, drying or incineration of sludge, etc. Harmful processing can effectively reduce pollution and improve waste conversion. For modern sewage treatment plants, sludge treatment and disposal has become the most complicated and costly part of the sewage treatment system. [0003] However, the existing sludge comprehensive treatment method is not efficient for the harmless treatment and treatment of sludge, and the conversion rate of the product after treatment is low; therefore, it does not meet the existing needs, so we propose a sludge comprehensive treatment method Approach. Contents of the inventi...
