'One-stop' solution system and 'one-stop' solution method for tap water plant sludge treatment

Abstract

The invention relates to the field of sludge treatment, and in particular relates to a 'one-stop' solution system and a 'one-stop' solution method for tap water plant sludge treatment. The 'one-stop' solution system comprises a high-efficiency sludge deep-dehydration system and a high-efficiency sludge recycling system, wherein the high-efficiency sludge deep-dehydration system comprises a sludge conditioning unit, a sludge modification unit, a sludge flocculation unit, a sludge precipitation unit and a sludge dehydration unit; and the high-efficiency sludge recycling system comprises a water permeable brick manufacturing system and an ordinary Portland cement production system. After the system and the method are adopted, the sludge of a tap water plant is effectively reduced and recycled; and furthermore, the system and the method are free from secondary pollution, small in floor area, low in investment and operating cost, automatic in control of the whole process as well as safe and easy in operation.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a "one-stop" solution system and method for sludge treatment in waterworks. Background technique [0002] At present, most urban waterworks draw water from surface water sources such as rivers, lakes, and reservoirs. The raw water undergoes processes such as coagulation, sedimentation, filtration, and disinfection to remove impurities in the raw water and produce water that meets the Hygienic Standards for Drinking Water. (GB5749-2006) of the finished water. [0003] While producing finished water, the waterworks also produce a large amount of sewage and sludge. The sewage mainly comes from the sludge discharge water from the sedimentation tank and the backwash wastewater from the filter, accounting for about 4% to 7% of the total clean water. At present, more than 95% of the waterworks in our country do not have sewage and sludge treatment facilities, and they are directly disch...

AI Technical Summary

Problems solved by technology

[0005] 1) The period required for sludge treatment is long. On the one hand, the effective volume of the treatment structure is large, and the equipment configuration power is high or the number is large, resulting in high infrastructure costs for treatment facilities; on the other hand, the equipment runs for a long time, resulting in high power consumption;

[0006] 2) The concentration and dehydration effect of the current chemicals on the sludge from the waterworks is poor, resulting in a large dosage of chemicals and high operating costs during the sludge treatment process;

[0007] 3) The process route of the system is complicated, the equipment is various, and the operation and maintenance are inconvenient;

[0008] 4) Low degree of recycling of sludge from waterworks
