Description

Tyre production enterprise waste water treatment process
Technical field
The invention belongs to environment-protective water processing technology field, be specifically related to a kind of tyre production enterprise waste water treatment process.
Background technology
Tire plant wastewater flow rate is that every acid etching processing 30kg tire produces waste water 0.0001m 3, containing sour 2.5g/L, chloride containing iron <5g/L in waste water, sulfur acid iron 5g/L etc., waste water need through neutralization precipitation process.Tire plant and technical rubber goods factory every infuse 30kg tire produces waste water 0.001m 3, goods per ton produce waste water 40-45m 3, containing soap 0.1g/L, calcium chloride 5g/L in waste water, glue juice 10-30g/L etc., generally need through coagulating sedimentation and filtration treatment.
The wastewater flow rate of each factory cooling tire and goods is: every 30kg tire produces 0.2-0.3m 3waste water, can reach 10-15m according to different production technique goods per ton 3, it is main containing talcum powder 3-8mg/L in water.In addition, brass plating piece waste water, Cleaning Wastewater, sulfuration waste water, reclaimed rubber waste water etc. are also produced.Various wastewater flow rate is little, pollutes and does not weigh, can enter Urban Underground water channel after the Local treatment of workshop.
The main raw material of tire production is rubber, and rubber production waste water comprise in glue production process, solidify and diluted latex, washing grumeleuse and glue machine with water, and a large amount of whey of fresh latex and do not solidify part.As long as concentrated natural latex production line rubber-clear freezing waste discharge, its pollutent has dissolved organic matter, ammonia-state nitrogen and sulfate radical etc., caouttchouc is then the machine water of washing grumeleuse and glue, and major part is dissolved organic matter, also has the magazine such as silt, leaf.These waste water contain two kinds of main potential pollutents, organic carbon and ammonia-state nitrogen, are just directly discharged into surface water body if unprocessed, that will exhaust the dissolved oxygen in water, cause a large amount of algal grown, hydrobiont occurs thereupon and suffocates, serious threat is formed to ecotope.
Rubber production be in petrochemical industry with one of water draining rich and influential family.Its draining water quality is complicated, and variation is comparatively large, more difficult.The main products of ordinary rubber is cis-1,4-polybutadiene rubber and styrene-butadiene rubber(SBR).Main factory effluent is along fourth waste water and butylbenzene waste water.Its wastewater treatment process is: butylbenzene waste water mixes in the duct after air supporting with along fourth waste water, after precipitation oil removal, enters wastewater treatment biochemical treatment, discharge after rapid filter filters.
