Abstract
The invention relates to a treatment process of sludge from a turbid circulating system of a steel enterprise hot rolling factory, and the process comprises the following steps: directly pumping sludge generated during water treatment of a turbid circulating system of a steel enterprise hot rolling factory into an oxide scale pit by a sludge pump, performing natural filtration to separate water from the sludge, mixing the sludge with coarse-grained oxide scale for outward transport together, allowing the water obtained after filtration to enter a whirling well at a low position in a gravity flow mode. Water in sludge is removed by the natural filtration of the oxide scale pit; the process is simple; the operation and management are very convenient; no mechanical equipment such as a filter press, a high-lift sludge pump, and the like is required; intermittent operation can be adopted, which saves a lot of water resources; a certain number of project construction land are saved; a lot of civil construction and equipment investment is saved; a lot of operation management cost is saved; a lot of energy consumption is saved; labor intensity of operators is greatly reduced; and secondary pollution caused in sludge treatment is prevented.
Description
Technical field
The invention belongs to the sewage treatment technology field, relate to a kind of technology simple, operate and manage very convenient and practice thrift the turbid loop systems sludge treatment technique of iron and steel enterprise's hot rolling mill
of cost.
Background technology
As shown in Figure 1; The existing turbid loop systems water technology of iron and steel enterprise's hot rolling mill is that the direct water coolant of hot rolling mill equipment is flowed in the iron sheet ditch of workshop; Eddy flow well outside flowing to the workshop; Remove the bulk iron scale at the eddy flow well through deposition, deliver to chemical oil remover (or delivering to horizontal sedimentation tank, process high rate filter filtration again) to remove fine particle iron scale and oil removing by the water pump pressurization then.The chemical oil remover water outlet is delivered to cooling tower after pump pressurization, water temperature is cooled to continues to recycle after temperature required again.As shown in Figure 2; The existing turbid loop systems sludge treatment technique of iron and steel enterprise's hot rolling mill is that mud that is precipitated by chemical oil remover in the turbid loop systems water treatment procedure of iron and steel enterprise's hot rolling mill or filter backwash mud are got into sludge sump, after whisking appliance stirs, squeezes into sludge thickener with sludge pump then, squeezes into plate-and-frame filter press with the higher sludge pump of lift again; Mud press dry the back outward transport; Filter back water is back to turbid loop systems, entire treatment process relative complex, and operate and manage very trouble; Need long-play equipment, sludge treating system running cost is higher.
Summary of the invention
For overcoming above-mentioned technical disadvantages, the present invention provide a kind of technology simple, operate and manage very convenient and practiced thrift the turbid loop systems sludge treatment technique of iron and steel enterprise's hot rolling mill
of cost greatly.
The present invention solves the technological method that its technical problem adopts: the turbid loop systems sludge treatment technique of a kind of iron and steel enterprise hot rolling mill; Its process step is: the mud that is produced in the turbid loop systems water treatment procedure of iron and steel enterprise's hot rolling mill is directly squeezed in the iron scale hole with sludge pump from sludge sump earlier; After natural filtration; Water is separated with mud, and mud is used the eddy flow well that gets into low level from stream mode with together outward transport after coarse grained iron scale mixes, filter back hydromining.
Said steam piano adopts vertical long shaft pump, adopts two vertical long shaft pumps of the using and the reserved simultaneously.
Skeleton construction is adopted in said iron scale hole, and bottom, iron scale hole is by the infiltration design.
The reinforced concrete water pond structure is adopted in said cyclone sediment pond.
The invention has the beneficial effects as follows: utilize the natural filtration effect in iron scale hole to remove the moisture in the mud, need not the mud that any filter-pressing device is handled the turbid loop systems of iron and steel enterprise's hot rolling mill; Technology is simple, operates and manage very convenient, need not mechanical means such as pressure filter, high-lift sludge pump; Can adopt periodic running, need not operation continuously in 24 hours; Water after filtering flow back into the eddy flow well of water treatment system again, practices thrift great lot of water resources; Saved the project construction land used of some amount, common sludge treating system needs the soil of certain area to be used for building the sludge treatment device facility.And the construction land of iron and steel enterprise is generally all very nervous, and this invention can contribute for iron and steel enterprise reduces the project construction land used; Saved a large amount of civil engineerings and facility investment, a cover sludge dewatering system comprises the sludge dewatering machine room of plate-and-frame filter press, air compressor machine, sludge pump, mud scraper, stirrer, pipeline, valve, electrical equipment, robot control system(RCS), sludge thickener and at least two floors; Saved a large amount of operational and administrative expensess, the operation of sludge dewatering system needs the operations staff of some amount, maintenance of the equipment maintenance, managerial personnel, also needs spare parts, instrument, material of some amount etc., and operational and administrative expenses is very high; Saved a large amount of energy consumptions; Plate-and-frame filter press needs sludge pump under big pressure condition, mud to be squeezed in the sheet frame to press dry; Need to consume a large amount of electric energy, in addition, also need consumed power with the supporting hydraulicefficiency system of plate-and-frame filter press, plate pulling device, bucket, air compressor machine etc.; Significantly reduce labor intensity of operating personnel, common sludge treating system needs a large amount of operator's 24 continuous throughout the twenty-four hour24s.But adopt the present invention's periodic running, only day time operation can be handled the whole mud of the turbid loop systems of iron and steel enterprise's hot rolling mill; Avoided the secondary pollution that brings in the sludge handling process, common sludge treating system leakage phenomenon occurs through regular meeting in operational process, influence environmental health, also causes environmental pollution.In addition, the filter cloth of plate-and-frame filter press need regularly clean after operation for some time, and these waste water that clean filter cloth also can bring environmental pollution.
