Method for regulating peak of natural gas and purifying water quality by utilizing hydrate

The invention relates to a method for regulating the peak of natural gas and purifying the water quality by utilizing hydrate. The method comprises the following steps: a, carrying out refrigeration and heat production through a screw rod compressor and an evaporator; b, conveying cooling water into a hydrate slurry generation kettle; c, regulating pressure of the natural gas through the compressor and adjusting the temperature through a heat exchanger and introducing the natural gas into the hydrate slurry generation kettle to be sufficiently mixed with the cooling water, so as to generate hydrate slurry; d, separating the hydrate slurry: carrying out three-phase separation on the hydrate slurry through a three-phase separator; e, decomposing the hydrate in a hydrate storage tank; f, purifying water: filtering through a pressure type ultra-filtration membrane assembly to purify the water quality. According to the method provided by the invention, advantages of the hydrate slurry withgood flowability and the
