Abstract
A kind of sulfur-containing waste water treatment process, comprising the following steps: (1) sulfur-containing waste water is introduced into conditioning tank, while lime is added and is mixed；(2) mixed sulfur-containing waste water introduces balancing tank, stands 1 ~ 2h；(3) sulfur-containing waste water after standing introduces chemical agent mixing pit, and organic sulfur polymer and molysite is added in chemical agent mixing pit, reacts 1.5 ~ 2.2h；(4) clarifying basin is introduced after the sulfur-containing waste water reaction in chemical agent mixing pit, flocculant is added in clarifying basin, by 2 ~ 2.8h of sulfur-containing waste water coagulating sedimentation；(5) sulfur-containing waste water of coagulating sedimentation introduces waste liquid medium filter and is filtered；(6) filtered waste water is introduced into reservoir for use.
Description
Technical field
The invention belongs to sewage treatment related fieldss, and in particular to a kind of sulfur-containing waste water treatment process.
Background technique
Increasingly strict with national environmental protection policy, most thermal power plants are assembled with waste water disposal facility, processing
Waste water mainly includes production waste water, sanitary wastewater.Using the fired power generating unit of wet desulfurizing process, the desulfurization in waste water is produced
Waste water accounts for comparable specific gravity in total discharge of wastewater.Desulfurization wastewater contains a large amount of impurity, as suspended matter, inorganic ion,
Heavy metal ion etc..The prior art is that desulfurization wastewater is done purified treatment and is emitted into water body after being adjusted to neutrality, and is still deposited
In very big pollution hidden trouble.
The world today, water resource is more and more in short supply, if desulfurization wastewater is become recyclable using certain technique
Water resource, the meaning and the benefit of generation generated will be apparent that.Desulfuration waste water treatment process basic step nothing more than in
With flocculation, precipitating and outlet.Many desulfuration waste water treatment process newly developed in recent years, such as evaporation, reuse, clarification technique,
Although this kind of technique can play a role to the recycling of desulfurization wastewater, problem is also relatively more, than if you need to newly-increased
A large amount of installations and facilities take up a large area, invests that big, process flow complexity, equipment failure rate is high, operational effect is undesirable, de-
Water is ineffective, specific resistance to filtration is inconvenient, there are high-salt wastewater outlet phenomenons etc..If these problems cannot be good
It solves, will seriously affect the industrial application of various desulfuration waste water treatment process.
Summary of the invention
The present invention aiming at the shortcomings in the prior art, provides a kind of sulfur-containing waste water treatment process.
The present invention is solved the above problems using following scheme: a kind of sulfur-containing waste water treatment process, comprising the following steps:
(1) sulfur-containing waste water is introduced into conditioning tank, while lime is added and is mixed；
(2) mixed sulfur-containing waste water introduces balancing tank, stands 1 ~ 2h；
(3) sulfur-containing waste water after standing introduces chemical agent mixing pit, be added in chemical agent mixing pit organic sulfur polymer and
Molysite reacts 1.5 ~ 2.2h；
(4) clarifying basin is introduced after the sulfur-containing waste water reaction in chemical agent mixing pit, flocculant is added in clarifying basin, by sulfur-bearing
Coagulating waste water precipitates 2 ~ 2.8h；
(5) sulfur-containing waste water of coagulating sedimentation introduces waste liquid medium filter and is filtered；
(6) filtered waste water is introduced into reservoir for use.
Further, the precipitating waste residue in the balancing tank and clarifying basin introduces solid mixing pit and is focused on.
The utility model has the advantages that the present invention has equipment layout structure reasonable, cost input is low, good operation stability, working efficiency
High, land occupation is less.
Specific embodiment
A kind of embodiment: sulfur-containing waste water treatment process, comprising the following steps:
(1) sulfur-containing waste water is introduced into conditioning tank, while lime is added and is mixed；
(2) mixed sulfur-containing waste water introduces balancing tank, stands 1 ~ 2h；
(3) sulfur-containing waste water after standing introduces chemical agent mixing pit, be added in chemical agent mixing pit organic sulfur polymer and
Molysite reacts 1.5 ~ 2.2h；
(4) clarifying basin is introduced after the sulfur-containing waste water reaction in chemical agent mixing pit, flocculant is added in clarifying basin, by sulfur-bearing
Coagulating waste water precipitates 2 ~ 2.8h；
(5) sulfur-containing waste water of coagulating sedimentation introduces waste liquid medium filter and is filtered；
(6) filtered waste water is introduced into reservoir for use.
Further, the precipitating waste residue in the balancing tank and clarifying basin introduces solid mixing pit and is focused on.
