Description
Technical field
The utility model relates to sewage treatment area, particularly relates to the process recovery system of a kind of oil refining and chemical engineering sewage.
Background technology
There are nearly 50 national serious water shortages in the current whole world, and united state of China confirms as one of serious water shortage country.But China about has hundreds of hundred million tons not utilize through the utilizable sewage of advanced treatment to be every year discharged, and causes the waste of water resources, wherein oil refining, chemical industry use water rich and influential family, meanwhile, is also the rich and influential family polluting large natural environment.Therefore, realizing sewage recycling has been the task of top priority.
The formation of so-called " sewage " is formed through production process is contaminated by fresh water.We will utilize sewage just dirty water pollutant must be removed as much as possible, and pollutent mainly contains: oil, organism, suspended substance, organic salt etc.
The patent No. " CN200520130414.2 " " recovery and utilization equipment of oil refining and chemical engineering sewage " adopts reverse osmosis membrane processing sewage, the degree of purification of polluted water obtains lifting to a certain degree, produce water also can recycle, but dense water often can not qualified discharge or do not allow discharge, sewage discharge process problem does not thoroughly solve.
Summary of the invention
The technical problems to be solved in the utility model is to provide the process recovery system of a kind of oil refining and chemical engineering sewage, the basis of the patent No. " CN200520130414.2 " " recovery and utilization equipment of oil refining and chemical engineering sewage " concentrates the dense water of reverse osmosis unit again through reverse osmosis membrane or nanofiltration membrane, produce water and enter desalination pond, dense water enters mechanical vapor-compression system, the principle adopting vapour compression concentration and evaporation is condensed water and solid crystal dense water evaporative condenser, condensed water sends into desalination pond, xln recycles or presses solid waste process, reach the object of not outwardly waste discharge.
For reaching above-mentioned purpose, the process recovery system of a kind of oil refining of the utility model and chemical engineering sewage, this equipment comprises the following device be mechanically linked in sequence together: hybrid reaction groove, multistagely join biological filter, anti-blocking air flotation pool, clean water basin, accurate filter, ejector, ozonizer, mixing tank, intermediate pool, biologic active carbon filtration device, water purifying tank, hollow fiber ultrafiltration film or microfiltration membrane and reverse osmosis membrane apparatus, wherein on the ozonizer outlet that is attempted by anti-blocking air flotation pool respectively and ejector, this device also comprises reverse osmosis membrane or nanofiltration membrane and mechanical vapor-compression system, the water outlet of reverse osmosis membrane apparatus is divided into two pipelines, one of them pipeline and reverse osmosis membrane or nanofiltration membrane and mechanical vapor-compression system link together, another pipeline and desalination pond link together.

The utility model difference from prior art is that the utility model achieves following technique effect:
The utility model equipment by adding reverse osmosis membrane or nanofiltration membrane and mechanical vapor-compression system after reverse osmosis membrane apparatus, the dense water of reverse osmosis unit is concentrated through reverse osmosis membrane or nanofiltration membrane again, produce water and enter desalination pond, dense water enters mechanical vapor-compression system, the principle adopting vapour compression concentration and evaporation is condensed water and solid crystal dense water evaporative condenser, condensed water sends into desalination pond, and xln recycles or by solid waste process, reaches not the object of outwardly waste discharge.
Reverse osmosis membrane effect above carries out desalination to the water outlet of device before, making it produce water is de-salted water, dense water is Halite water, for increasing reuse water water production rate, also later crystallization burden is reduced, add again one section of reverse osmosis membrane to the last period reverse osmosis membrane dense water concentrate further, the dense water yield is reduced further, and nanofiltration membrane also can play concentrating and desalinating effect.
The ton Chemicals water loss external at petrochemical system is starkly lower than China, and as processed 1 ton of crude oil water loss abroad below 0.5 ton of fresh water, and China is on average about 1.5.If sewage not reuse, ton crude oil processing water loss be down to less than 1.0 be do not have possible.That is reusing sewage is water-saving and emission-reducing, reduces the Bi Hangzhi road of ton crude oil water loss.Its economic benefit is also fairly obvious, and general city fresh water is all more than 2.00 yuan, and some place is higher.And reusing sewage cost (comprising the expenses such as depreciation) is generally between 0.65-0.70 unit ton (not desalination), general medium-sized petrochemical plant reusing sewage water field scale is in 12000-24000 ton/sky, for 12000 tons/day, fresh water deducts cost 0.70 yuan/ton by 2.00 yuan/ton, for profit per ton 1.40/ yuan of ton, within 1 year, can save water rate is 613.2 ten thousand yuan/year.
What more than calculate is economic benefit without embrane method desalination, if the economic benefit after desalination is more obvious.General de-salted water is 70% of sewage total amount, so desalination water yield is 12000*0.70 ton/sky, such reuse water cost is greatly between 2.00-2.50 yuan/ton, and desalination water price is between 8.50-13.00 yuan/ton, calculate with its minimum rate: 12000*0.70* (8.50-2.00) * 365=1992.9 ten thousand yuan/year.So, within 1 year, will save nearly 20,000,000 yuan, the annual sewage discharge also reducing 4,380,000 tons is simultaneously gone in rivers,lakes and seas.
