Description

A kind of industrial sewage is treatment unit again

Technical field

The utility model relates to chemical industry treatment unit, particularly a kind of industrial sewage treatment unit again.

Background technology

China is populous, and the major reason that causes China's water resources deficiency is that industrial sewage quantity discharged is large.Industrial sewage refers to waste water, the waste liquid producing in Industrial processes, wherein contains in the industrial production materials, intermediate product and the product that outflow with water and production process and produces environment is produced to the pollutent destroying.For example acid waste water, alkaline waste water, cyanide wastewater, chromate waste water, cadmium wastewater, mercury-containing waste water, phenolic wastewater, aldehyde-containing sewage, oily(waste)water, sulfur-containing waste water, containing organophosphorus waste water and radioactive wastewater, these industrial sewages have caused resident's cancer syndrome in some place.

Therefore need to process industrial sewage, the chemical devices using at present needs constantly to consume industrial chemicals, and has sludge creation again, the water reuse difficulty of discharge, and floor space is larger; Ferrite device in use needs heating, and energy consumption is high, exists and processes the rear high shortcoming of salinity.

Summary of the invention

Solve the problem that background technology exists, the technical scheme adopting is as follows: a kind of industrial sewage again treatment unit is comprised of grating tank, reactive tank, biochemistry pool, filtration tank, adsorption tower, readjustment pond, delivery pipe, pipeline, it is characterized in that: grating tank is by pipeline ligation groove, reactive tank connects biochemistry pool by pipeline, biochemistry pool connects filtration tank by pipeline, filtration tank connects adsorption tower by pipeline, and adsorption tower connects readjustment pond by pipeline, and readjustment pond connects delivery pipe.

Described grating tank is comprised of settling tank, coarse rack pond, fine fack pond, and settling tank is on coarse rack pond, and fine fack pond is below coarse rack pond.

Described reactive tank the inside arranges flocculant of polymeric aluminium chloride interval, coagulant aids is interval, defoamer is interval.

Described biochemistry pool the inside arranges anoxic pond interval and Aerobic Pond interval.

Advantage of the present utility model is: reduce energy consumption, effect is good.

Accompanying drawing explanation

Fig. 1 is a kind of industrial sewage frame construction drawing for the treatment of unit again.

Embodiment

A kind of industrial sewage is as shown in Figure 1 the frame construction drawing for the treatment of unit again, a kind of industrial sewage again treatment unit by grating tank 1, reactive tank 3, biochemistry pool 5, filtration tank 7, adsorption tower 9, readjustment pond 11, delivery pipe 12, pipeline 2, pipeline 4, pipeline 6, pipeline 8, pipeline 10 forms, it is characterized in that: grating tank 1 is by pipeline 2 ligation grooves 3, reactive tank 3 connects biochemistry pool 5 by pipeline 4, biochemistry pool 5 connects filtration tank 7 by pipeline 6, filtration tank 7 connects adsorption tower 9 by pipeline 8, adsorption tower 9 connects readjustment pond 11 by pipeline 10, readjustment pond 11 connects delivery pipe 12.

Described grating tank 1 is comprised of settling tank 100, coarse rack pond 101, fine fack pond 102, and settling tank 100 is on coarse rack pond 101, and fine fack pond 102 is below coarse rack pond 101.

Described reactive tank 3 the insides arrange flocculant of polymeric aluminium chloride interval 31, coagulant aids interval 32, defoamer interval 33.

Described biochemistry pool 5 the insides arrange anoxic pond interval 51 and Aerobic Pond interval 52.

When using, the settling tank 100 that first industrial sewage enters in grating tank 1 precipitates, then enter coarse rack pond 101 and carry out dirt and filter roughly, the sewage after filtering by coarse rack pond 101 enters fine fack pond 102 by the larger contamination filtrating of volume in sewage; By pipeline 2, enter into reactive tank 3 the insides, reactive tank 3 the insides are provided with flocculant of polymeric aluminium chloride interval 31, coagulant aids interval 32, defoamer interval 33, flocculant of polymeric aluminium chloride interval 31 makes trickle suspended particles and elimination of colloid stability in sewage, assemble, flocculation, coagulation, precipitation, reach purifying treatment effect, coagulant aids interval 32 makes flocculant of polymeric aluminium chloride strengthen coagulation effect, the a large amount of foams that rise in treating processes, defoamer interval 33 prevents that sewage disposal device is because of a large amount of excessive danger of blasting of foam inside pressure; Industrial sewage in reactive tank 3 enters the anoxic pond interval 51 of biochemistry pool 5 by pipeline 4, microorganism in active sludge first discharges phosphorus at this, and breeding, when entering Aerobic Pond interval 52, because oxygen is sufficient, microorganism absorbs phosphorus and the organism in water in a large number; Then industrial sewage enters filtration tank 7 from the tower top of filtration tank 7 by pipeline 6, and the charcoal filter of filtration tank 7 inside goes the de-chlorine ﹑ of look ﹑ to go the heavy gold genus of organic matter removal ﹑ ﹑ to close into and washes materials such as washing agent ﹑ virus and radioactivity; From filtration tank 7 sewage out, by pipeline 8, enter adsorption tower 9, sewage carries out deodorizing processing in adsorption tower 9, reaches nature taste; Then by pipeline 10, enter in readjustment pond 11 and carry out sewage pH-value balance, after test meets emission standard, by delivery pipe 12, discharge, if do not met, continue to carry out pH-value balance in readjustment pond 11, until meet.

Finally explanation: above are only explanation embodiment of the present utility model; be not limited to the utility model; technology people for utility model; all within principle of the present utility model; any modification of doing, replacement etc., all within being included in protection domain of the present utility model.
