For substance stable suspersion in sewage, water-oil separating speed is slow, and removal is difficult.In order to accelerate water-oil separating, need to add degreaser,
A large amount of medicaments such as flocculant or flotation agent, flocculation aid, dosage from tens mg/L to 200mg/L, high reachable 600mg/L with
On.
A large amount of dosings lead to a series of problems:
1, cost of sewage disposal is high, and reagent cost is up to 0.6-2.1 member/m3Water, part oil field subtract because medicament expense is insufficient
Few dosing, causes water quality not up to standard.
2, adding of agent causes sludge yield big, such as triumph isolated island oil recovery factory, and sewage adds dirt caused by medicament according to statistics
Mud amount increases by 30% or so.In terms of 100mg/L, the sludge quantity that pure medicament generates is 0.3 side's mud/1000 side's water (moisture content
70%).Treatment of Sludge cost is up to 236.6 yuan/side, and a large amount of sludge bring heavy burden to oil field production run.
Electrochemistry sewage treatment process is sewage treatment process emerging in recent years, has many advantages, such as less developer, is claimed
