Description
Technical field
The utility model relates to a kind of waste disposal plant, especially a kind of waste water and waste liquid Integrated Processing Unit.
Background technology
Waste water and waste liquid come from people's production and life, are divided into usually being easier to handle low concentration wastewater and reluctant high-concentration waste liquid, and the former the common water yield is big, and pollutant load is low, possesses reusable economy; The common water yield of the latter is little, and pollutant load is very high, can't reuse substantially.
Waste water is to be divided into the sanitary sewage that focuses on via city domestic sewage treatment plant, or the comprehensive trade effluent from production technique handled of industrial sewage treatment plant, comprehensive trade effluent come from such as: recover the oil, oil refining, petrochemical industry, electric power, metallurgy, automobile, PCB is electroplated in shipbuilding, dyeing and weaving, and chemical enterprise such as pharmacy, plastics, chemical fibre.Usually specific conductivity is in 1-10 milli Siemens/cm, COD＜1,000 mg/litre, the sewage of ammonia nitrogen＜100 mg/litre, the productive life waste water that pollution concentration is lower enters treatment plant usually, the pollutent that adopts the biochemical process of relatively low cost to reduce more than 90% reaches effluent standard, and biochemical processing process mainly is divided into three ranks, and emphasis is in one-level: reinforced deposition; Secondary: strengthen decarburization; Three grades: denitrogenation dephosphorizing.What generally adopt now is tertiary treatment technology on one-level secondary basis, the main difficult point of tertiary treatment technology is denitrogenation, because the denitrogenation in the ordinary student metallization processes realizes by nitrated-denitrification, nitration processes need expend a large amount of oxygen the ammonia-state nitrogen in the waste water is oxidized to nitric nitrogen by nitrobacteria, under anaerobic state, be nitrogen with nitrate-nitrogen reduction then by denitrifying bacterium, owing under good oxygen condition, consumed a large amount of carbon sources, and often face carbon source at the denitrification state, the basicity deficiency, can't provide enough nutrient reduction nitrogen for denitrifying bacterium, three grades of biochemical process of great majority need add carbon source (being generally methyl alcohol), and basicity is replenished.This contradiction makes that the tertiary treatment technical process is long, and efficient is low, expends a large amount of energy.
Three grades of qualified discharge water can reuse, can be directly used in greening as middle water, spray, water coolant also can be used for more high-grade productive life water for high-grade water by conventional membrane process purification, but adopt conventional membrane technique to face a contradiction, the waste water water yield that is exactly the purification generation is big, and the concentration height often becomes another source of pollution, to pollute required investment very big and administer this part, offset the economic benefit that the water recycling is brought.
