Sludge reduction system
Details:

System overview

The company launched a complete set of sludge solutions, using modular process combination, according to the needs of customers, reasonable combination, ensure the close connection of each process section, ensure the stability, continuity, intelligence and energy saving of sludge system, so as to realize the reduction of sludge disposal.

Scope of application

Sludge from municipal sewage, breeding sewage, slaughtering sewage, food processing sewage, pharmaceutical sewage, chemical sewage, printing and dyeing sewage, papermaking sewage, mine washing sewage, etc.


Applicable sludge types

Untreated raw sludge (98-99.5% moisture content)

Concentrated sludge (moisture content 95-97%)

Sludge after mechanical primary dewatering (75-85% moisture content)

Sludge (moisture content 55-65%) after deep mechanical dewatering


Sludge disposal in later stage

1. Mixed burning

Dry mud has a high calorific value, and using dry mud as auxiliary fuel can reduce the consumption of raw coal.

(1) When the water content of sludge is higher than 70%, its economy is negative, and it has no use value without any subsidy; when the water content of sludge is 20%, 3.93 tons is a ton of raw coal, which can be mixed with 5% - 10% sludge;

(2) Dioxins are easy to form when the temperature is below 800 ℃ and disappear when the temperature is above 800 ℃ to 1000 ℃, so long as the sludge is not mixed during the start-up and shutdown of the boiler.


2. Utilization of cement plant

The calorific value of dry sludge can be used as part of the alternative fuel for cement clinker production, and the incineration residue can replace the silicon and aluminum raw materials used in clinker production to realize sludge recycling.


3. Use of building materials

It has been proved by scientific analysis that it is not advisable to use sludge directly in brick making. Sludge incineration ash can be used as the filling material of wood like building materials, and its dosage is more than 65%. The added value of the product is high, and the application market prospect is good.


4. Sanitary landfill


Treatment effect

The moisture content of the final sludge is about 10-30%, and the volume is only 1 / 100-1 / 500 of the initial sludge (98-99%).
