Description
Technical field
The utility model relates to a kind of waste disposal plant, particularly relates to a kind of oily(waste)water combined treatment device.
Background technology
A lot of waste water can be produced in industrial production, comprise sanitary sewage, ground flushing waste water, cleaning of evaporator waste water and tank field early-stage rainwater etc.The pollution substance contained in these sewage has petroleum-type, potassium bichromate (COD
cr) and suspended substance etc.
If these oil-water mixtures directly discharge, great destruction will be caused to environment.
Oil generally exists with three kinds of forms in water, is respectively: float and oil---refer to that elaioleucite particle diameter is greater than 50um, the oil that static for some time can float voluntarily; Dispersed oil---refer to elaioleucite particle diameter less be 10 ~ 50um, be scattered in water, leave standstill the oil that can float through the long period; Oil in water emulsion---refer to that elaioleucite particle diameter is less of below 10um, leave standstill the oil that can not float, be generally because using tensio-active agent or mechanical effect to make oily emulsification institute form stable dispersion system, the oil of oily(waste)water mainly to exist with the form of dispersed oil to float to oil, and sewage is milkiness shape.
Summary of the invention
The purpose of this utility model is to provide a kind of containing greasy dirt combined treatment device, this device mainly oils and feature that dispersed oil form exists with floating for the oil of oily(waste)water, pollution in oily(waste)water, with the process combination device of materializing strategy, can all be removed by composition.
The purpose of this utility model is achieved through the following technical solutions:
A kind of oily(waste)water combined treatment device, device described in it comprises sewage storage pond, equalizing tank, efficient degreasing tank, grease removal tank, the first intermediate pool, one-level air floatation machine, scum silica frost storage pool, scum silica frost subsider, sludge dewatering equipment, the second intermediate pool, secondary air-floatation machine, the 3rd intermediate pool, walnut shell filter, outlet sump; Aforesaid device, facility are connected as follows successively: sewage storage pond is connected with equalizing tank, and is connected with efficient degreasing tank, the first intermediate pool, one-level air floatation machine; Second intermediate pool is connected with secondary air-floatation machine, the 3rd intermediate pool, walnut shell filter, outlet sump.
Described a kind of oily(waste)water combined treatment device, described efficient degreasing tank is also connected with oil reservoir.
Described a kind of oily(waste)water combined treatment device, described one-level air floatation machine is also connected with scum silica frost storage pool, scum silica frost subsider, sludge dewatering equipment.
Advantage of the present utility model and effect are:
The utility model is for the oil of oily(waste)water mainly with the floating feature existed with the form of dispersed oil that oils, and take materializing strategy, sewage treatment capacity reaches 250m3/d, main Wastewater Pollutant petroleum-type≤5000mg/L, COD
cr≤ 3000mg/L.Pollution in oily(waste)water all can be removed.
Accompanying drawing explanation
Fig. 1 is a kind of oily(waste)water combined treatment device of the utility model compositional block diagram.
Embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of oily(waste)water combined treatment device of the utility model, its oil reservoir is connected with efficient degreasing tank, scum silica frost storage pool, scum silica frost subsider and sludge dewatering equipment, one-level air floatation machine are by scum silica frost storage pool, and be connected with sludge dewatering equipment through scum silica frost subsider, walnut shell filter and outlet sump, it is the 3rd between intermediate pool and outlet sump.Concrete annexation is: device comprises sewage storage pond, equalizing tank, efficient degreasing tank, grease removal tank, the first intermediate pool, one-level air floatation machine, scum silica frost storage pool, scum silica frost subsider, sludge dewatering equipment, the second intermediate pool, secondary air-floatation machine, the 3rd intermediate pool, walnut shell filter, outlet sump; Aforesaid device, facility are connected as follows successively: sewage storage pond is connected with equalizing tank, and is connected with efficient degreasing tank, the first intermediate pool, one-level air floatation machine; Efficient degreasing tank is also connected with oil reservoir, and one-level air floatation machine is also connected with scum silica frost storage pool, scum silica frost subsider, sludge dewatering equipment; Second intermediate pool is connected with secondary air-floatation machine, the 3rd intermediate pool, walnut shell filter, outlet sump.
Equipment configuration described in the utility model runs as follows:
Sewage enters efficient degreasing tank after promoting in sewage storage pond and equalizing tank, and after leaving standstill, by the screening effect of gravity, oil slick and dispersed oil float to the water surface, then with Oil scraper and collection tube, the oil slick on top layer are isolated water body.The oil be separated, recycles after Cemented filling to oil reservoir.Water after the process of efficient degreasing tank, through the first intermediate pool, is then promoted to one-level air floatation machine by one-level lift pump and carrys out further oil removing.
At this moment in one-level air floatation machine, coagulant polymeric aluminium chloride (PAC) is added, make remaining dispersed oil in water, oil in water emulsion and and other pollutents form small flco, then non-ionic type polymeric flocculant (PAM) is added, the small flco that the coagulation stage is formed is condensed into big flocculating body, and improve alumen ustum intensity, improve pneumatically supported removal effect.The amount that its coagulating agent, flocculation agent add is depending on soil level.
After dissolved air floatation water discharges in sewage, form the oil in water emulsion in small bubbles adhesion sewage or suspended substance, form the three-phase system of water, gas and floss, hydrophobic floss and bubble incorporation emerge, then with scraper plate, scum silica frost platoon is entered scum silica frost storage pool, enter scum silica frost settling bowl through scum silica frost pipe, then utilize sludge dewatering equipment pollutent to be formed mud cake outward transport, the water after process enters the second intermediate pool by overflow weir and rising pipe.
Second intermediate pool collects the water outlet of one-level air floatation machine, is promoted to secondary air-floatation machine processes by air supporting two-stage hoisting pump.Simultaneously to secondary air-floatation machine dosing coagulant PAC, make dispersed oil a small amount of in water, oil in water emulsion and and other pollutents form small flco, then add flocculation agent PAM, the small flco that the coagulation stage is formed is condensed into big flocculating body, and improve alumen ustum intensity, improve removal effect by two-stage air supporting.
After two-stage air supporting, directly can be discharged in outlet sump by the 3rd intermediate pool during water quality reaching standard; Real-Time Monitoring is carried out to water outlet, if water quality still exceeds standard after two-stage air supporting, then set up walnut shell filter the 3rd between intermediate pool and outlet sump, it is utilize filtrate the interception function of oil and cohesion to be removed further to oil in sewage, to guarantee the qualified discharge of water outlet that walnut shell filter filters.
