Abstract

The invention relates to a process for producing purified water by adopting sewage. The process comprises a vaporization chamber (6), a liquefaction chamber (13) and a liquid heat exchange tank (15), and is characterized in that the vaporization chamber (3) and the liquefaction chamber (13) both carry out circulating heat exchange in a closed vacuum insulating layer (5); a heat storage body (8), a heater (2) and a temperature control probe (9) are arranged in the vaporization chamber (6); a heat exchanger (7), a forcible circulating inlet (12) and a liquid level controller (14) are arranged in the liquefaction chamber (13); and a methane tank (20) is arranged for sewage treatment of large cities.

Description

Sewage system pure water technology

Affiliated technical field

A kind of sewage disposal technology, particularly a kind of sewage system pure water technology.

Background technology

Sewage water treatment method has membrane technique; Quick-fried gas of mud and thermal treatment learn a skill, and wherein the quick-fried gas technology of membrane technique and mud is applied to be mostly to obtain middle water in the extensive water treatment, accomplishes qualified discharge; And can not accomplish recycle, and heat treatment technics is applied to the water treatment of torrid areas country more.

Summary of the invention

The invention provides water quality such as a kind of use heat treatment technology Treating Municipal Sewage, chemical engineering sewage, seawater, make water quality after the processing reach the degree of the drinkable recycling of high-quality pure water.Difficult in order to solve town water, marine, family uses the high-quality shipwreck of drinking, the problem that the chemical plant WWT is difficult.

Its technical scheme is: after sewage is vaporized, make solid-liquid separation, all solids material in the liquid is all separated out; Gas carries out heat exchange with sewage again; Its solution is to make sewage pass through to get into liquid heat exchange pond (15) behind the filter screen, pass through automatic control pump (29) then and get into liquefied room (13), heat exchanger (7) in and high temperature purification water and high-temperature steam get into vaporizing chamber (6) after carrying out heat exchange and in chamber (6), spray high temperature sewage liquid to vapour through spray thrower (10); Make liquid vaporization fully in vaporizing chamber; Solid matter is through thermal store (8), and well heater (2) falls, and discharges through solid matter relief outlet (1).Gas through steam export mouth (11) get into liquefied room (13) again with heat exchanger (7) in sewage carry out heat exchange; And liquefaction simultaneously; And then import liquid liquid interchanger (16) and sewage in the liquid heat exchange pond (15) and carry out flowing into water purification underpressure chamber (17) after the big area heat exchange completely and flow out through water purification valve (18); Accomplish sewage purification process; If then sewage is behind multilayer sewage filter net (28) in the urban sewage purification, throw out, mud etc. flow into methane-generating pit (26) naturally and in methane-generating pit, behind about 50 ℃ high temperature 2-3 hour aerogenesis, discharge the natural pond slag; The natural pond slag through settling chamber (22) air-dry or oven dry filtrating flow into get into once more after the reservoir (23) sewage inlet (19) natural pond slag through the natural pond slag derive machine (21) and derive and be used for fertilizer, fuel etc.; Biogas is derived by biogas export mouth (20), and (27) are the methane-generating pit well heaters, finally accomplishes the green whole process of handling of municipal effluent.Above equipment all is enclosed in vacuum heat-insulating layer (5) and the thermal insulation layer (3,4), and the 30th, the pump circulation outlet.

Its beneficial effect is: treatment effect is good, can become tap water to sewage, cycling and reutilization; Solve the not enough problem of Urban water supply, WWT is energy-conservation, and is efficient; Floor space is few, and treatment facility is changeable, can be used for boats and ships, seawater system tap water, recycled water in family system pure water; Unmanageable chemical engineering sewage such as paper mill, chemical plant is handled, and can obtain solid material and high-quality water simultaneously.
