Embodiment

[0035] The hydrate reaction in the reaction vessel of the device is affected by factors such as temperature, pressure, and reaction process; the hydrate dissociation reaction in the dissociation reactor of the device is affected by factors such as dissociation temperature and pressure, and the hydrate extraction and separation The process will produce a small amount of decomposition. The sludge rapid concentration test and the clean water discharge test are tested to simulate certain reaction environment parameters. The following is the implementation process of the patent test of the present invention:

[0036] (1) A rapid concentration and purification treatment device and method for hydrate sludge sludge rapid concentration test

[0037] Sludge rapid concentration test conditions: under the conditions of reactor temperature 8°C and reactor pressure 0.1Mpa, using quantitative HCFCR141b and sludge samples with a water content of about 97.81±0.01wt% from the sludge treatment pl...

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a rapid concentration and purification treatment device and method for hydrate sludge. Background technique [0002] With the rapid development of my country's social economy and the continuous advancement of urbanization, the discharge of sludge and sewage is also increasing, and the rate of sewage treatment plants and sewage treatment is also increasing year by year. The sewage treatment industry has developed rapidly in the past two decades. For example, my country's sewage treatment rate soared from less than 16.2% in 1998 to 95% at the end of 2017, with remarkable environmental benefits. Now the sludge treatment process has the following aspects: [0003] The composition of sludge is complex, containing organic matter, heavy metals, toxic substances, etc. If the sludge is not treated in a timely and reasonable manner, it will pose a great threat to the environment...
