Embodiment 1

[0030] Example 1: A sewage treatment plant in a city in Zhejiang Province produces 10 tons of sludge a day, 3,650 tons a year, and the outsourcing treatment fee per ton is 3,700 yuan, and the outsourcing fee for one year is 13.505 million yuan. At the same time, two people need to be hired to carry out Caretaker, the salary is 180,000 yuan a year, and the total annual sludge treatment cost is 13.685 million yuan.

[0031] After using this system, the moisture content of the sludge is controlled below 40%, 1,460 tons of sludge are produced a year, the annual outsourcing cost is 5.402 million yuan, and the total annual other costs are 150,000 yuan. The total annual sludge treatment cost is 555.2 ten thousand yuan. The new sludge dewatering and drying equipment for this system has a total investment of 750,000 yuan, saving 7.383 million yuan in the first year and 8.133 million yuan per year from the second year onwards.

Embodiment 2

[0032] Example 2: A domestic sewage treatment station in a residential area in Jiangsu produces 0.5 tons of sludge a day and 182.5 tons a year. The outsourcing treatment fee per ton is 3,200 yuan, and the outsourcing fee for a year is 584,000 yuan. At the same time, one Part-time staff, the salary is 50,000 yuan a year, and the total annual sludge treatment cost is 634,000 yuan.

[0033] After using this system, the moisture content of the sludge is controlled below 40%, 73 tons of sludge are produced a year, the annual outsourcing cost is 233,600 yuan, and the total annual other costs are 20,000 yuan. The total annual sludge treatment cost is 25.36 ten thousand yuan. The new sludge dewatering and drying equipment for this system has a total investment of 200,000 yuan, saving 180,400 yuan in the first year and 380,400 yuan a year in the second year.

Abstract

The invention discloses a sludge drying comprehensive treatment system which comprises a solar high-temperature evaporation chamber, a sludge crusher, a condensation heat exchange system, a temperature control device, a sludge drying chamber and a sludge collection tank, wherein the solar high-temperature evaporation chamber, the condensation heat exchange system, the temperature control device and the sludge drying chamber are connected in turn; and the solar high-temperature evaporation chamber, the sludge crusher and the sludge drying chamber are connected, and the sludge collection tank isarranged at the bottom of the sludge drying chamber. The invention provides a sludge drying comprehensive treatment system which is used for dehydrating and drying sludge by use of solar energy, andhas the advantages of high sewage treatment efficiency and low sludge treatment cost; and the invention also discloses a method using the system.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a sludge drying comprehensive treatment system. Background technique [0002] The total amount of sludge has increased sharply, and a large investment is urgently needed. At present, the annual output of sludge in my country is as high as about 70 million tons, including about 35 million tons of municipal sludge and 35 million tons of industrial sludge. Sludge is harmful, but the actual effective treatment rate is less than 25%. Therefore, it is necessary to promote the development of sludge treatment industry, reduce secondary pollution, and complete the water treatment industry chain. However, the current environmental protection industry generally has problems such as high water content in sludge and high cost of outsourcing treatment. Contents of the invention [0003] Purpose of the invention: Aiming at the deficiencies and defects of the prior art, the present invention p...
