Abstract
A process for treating the suspended substances in steel-rolling sewage includes such steps as removing magnetic particles by making the sewage flow through iron-sheet ditch and continuous magnetic particle remover, removing oil, cooling in cooling tower and collecting in pool. Its equipment is composed of water spraying tube, guide plate, water inlet, case body, magnetic blocks assembly, water outlet, chain, panel and side plate with two cyclic slots on its inner side. Said external slots are sealing slots and the internal slot is locating slide one.Its advantages are simple structure, less investment and continuous operation.
Description
The present invention relates to field of waste water treatment, be specially adapted to the purifying treatment of suspended substance in steel-rolling sewage processing and machine tooling waste liquid etc.
In the past, tertiary treatment is generally all adopted in the processing of suspended substance in steel-rolling sewage.One-level is the whirlwind-type settling tank, is called for short the eddy flow well, and secondary is horizontal flow basin (or swash plate pond, or dortmund's tank), and three grades is pressure filter or high-gradient electromagnetic filter, and its process flow diagram is seen accompanying drawing 1.That is: sewage such as steel rolling water coolant, wash-down water gather through the iron sheet ditch and flow into the eddy flow well, by gravity, centrifugal force oarse-grained iron sheet is deposited in the pond at the bottom of, sewage is squeezed into horizontal flow basin by pump, continues to utilize gravity that the suspended particle precipitation is removed.With after three grades pressure filter or high-gradient electromagnetic filter filter, sewage is purified.The slime water of secondary and tertiary treatment is sent to sludge dewatering system, and the sludge dewatering slagging is utilized again.
This conventional process flow is long, and the treatment unit floor space is big, and buried depth is big at the bottom of the pond, the cleaning of mud, gets rid of difficulty, the moisture percentage in sewage sludge height, thus also need sludge dehydration device to dewater, and pipeline easily stops up, and technology can not be worked continuously, the investment cost height.
The objective of the invention is to be to provide a kind of easy, the sewage by suspended thing treatment process and the device thereof of reducing investment outlay and can work continuously.
The object of the present invention is achieved like this:
This technology is: place continous way magnetic-particle remover in the iron sheet ditch, sewage such as steel rolling water coolant, wash-down water flow into the iron sheet ditch, continous way magnetic-particle remover in the iron sheet ditch, oarse-grained iron sheet, the iron filings that contain magnetic are adsorbed on the panel of continous way magnetic-particle remover, through guide plate magnetic-particle is separated with sewage, because of its water ratio less than 25%, so need not the dehydration, can directly recycle; At this moment, the suspended particle of sewage (SS) can be reduced to about 200～300mg/L, with pump sewage is squeezed into thereafter two-stage continuous magnetic-particle remover then,, further the SS in the sewage is reduced to below the 50mg/L by adjusting panel and the magnetic patch spacing and the processing water yield; Sewage after the processing through water-and-oil separator oil removing and cooling tower cooling, flows into clean water basin again, can recycle and can also discharge, and effluent cycle rate after treatment reaches more than 90%.Process flow diagram of the present invention is seen accompanying drawing 2.
The continous way magnetic-particle remover of this process using is to utilize rare earth Nd-Fe-B permanent magnets molectron absorption magnetic-particle, utilize guide plate to make magnetic patch and magnetic-particle distance widen and realize solid-liquid separation, use water jet standpipe, make magnetic-particle landing from the guide plate successfully.Continous way magnetic-particle remover comprises water jet standpipe, guide plate, motion-work wheel, water-in, casing, the magnetic patch molectron, water outlet, follow-up pulley, chain, side plate and panel, water jet standpipe is positioned at the guide plate top, guide plate is installed on the tangential direction of panel upper end, the magnetic patch molectron is made up of magnetic patch and magnetic patch back of the body bar, the magnetic patch molectron be contained in chain above, there are two annular recessess the inboard of two blocks of side plates, outer groove is a sealing groove, inner groovy is a positioning runner, two V-type side sealing blocks are embedded in the outer groove, insert panel between groove and the sealing block outside, by screw press strip fit sealing piece; Needle bearing is contained in the inner groovy, and the end that chain is had strong market potential is fixed in the interior cover of needle bearing, and the other end is fixed in the chain, and the clubfoot carrier bar is connected with chain, and on the clubfoot carrier bar, magnetic patch is positioned on the magnetic patch back of the body bar magnetic patch back of the body bar by screw retention.
The alternative existing suspended substance in steel-rolling sewage treatment process of technology of the present invention, can save floor space about 80%, save cost of investment about 60%, need not special sludge dehydration device, the day-to-day operation expense declines to a great extent, and the SS that handles in the sewage of back is lower than discharging standards, can recycle, can also directly discharge, have significant environmental benefit, economic benefit and social benefit.
The present invention is further illustrated below in conjunction with drawings and Examples.
