Abstract
The invention relates to a double-effect multifunctional organic sewage treatment agent, which is composed of polymeric aluminum, a high efficiency pulping papermaking advanced treatment agent and an organic polymer decolouring flocculating agent. wherein, the high efficiency pulping papermaking advanced treatment agent is a mixture of polymeric ferric sulfate and activated diatomite according to ratio of 4:6, and the organic polymer decolouring flocculating agent is a dicyandiamide-formaldehyde series quaternary amines type cationic polymer. The treatment agent is mainly used in an advanced treatment phase of waste water at intermediate section during a pulping papermaking process, and can improve the disadvantages of large medicinal amount of current single ordinary water, poor treatment effect and high treatment cost. The treatment agent has the advantages of small dosage amount per ton of water, high treatment efficiency and stable chroma clearance. Under the condition that the medicine addition amount accounts for 50% of the that of polymeric aluminum, the index of COD, chroma, SS, total phosphorus and the like of outlet water can reach or is better than national relative standard, and the operation is stable.
Description
One, technical field
The present invention relates to a kind of medicament of pulping paper-making medium wastewater advanced treatment, especially COD, colourity, SS, total phosphorus etc. are had the medicament of very high clearance.
Two, background technology
Pulp and paper industry is an industry closely bound up with national economy, also is simultaneously that an energy and industrial chemicals consume the industry high, that water consumption is big, environmental pollution is serious.Because the paper-making industrial waste water quantity discharged is big, contain a large amount of Mierocrystalline celluloses, xylogen, mineral alkali and tannin, resin, protein etc. in the waste water again, cause that chroma in waste water is dark, basicity big, hard-degraded substance content height, oxygen-consumption be big.It can cause the pollution of whole water body and the havoc of ecotope.Middle-stage wastewater then is the emphasis of whole pulp and paper waste_water.And decolour, fall COD is the difficult point that middle-stage wastewater is administered.Papermaking midcourse wastewater is handled and is extensively adopted Coagulation Method at present.The coagulating agent that adopts mainly contains mineral compound such as polymerize aluminum chloride, bodied ferric sulfate, Tai-Ace S 150, iron trichloride, aluminum chloride.They often exist ton water dosage big in the process of single use, and the sludge quantity of generation is big, and processing efficiency is not high, and ton water treatment agent cost height can not guarantee that colourity reaches the shortcoming of national relevant emission standards.
Three, summary of the invention
In order to overcome the deficiency of existing sewage disposal medicament commonly used, the multi-functional organic sewage treatment agent of economic benefits and social benefits provided by the invention ton water dosage is little, the processing efficiency height, and chroma removal rate is stable.It is made up of polymerize aluminum chloride, efficient pulping and paper-making advanced treatment agent and organic polymer decolor flocculating agent.
The technical solution adopted for the present invention to solve the technical problems is: respectively the polymerize aluminum chloride in the multi-functional organic sewage treatment agent of economic benefits and social benefits, efficient pulping and paper-making advanced treatment agent, organic polymer decolor flocculating agent are prepared by certain concentration.Wherein polymerize aluminum chloride, efficient pulping and paper-making advanced treatment agent be according to 10%～15% preparation, and the organic polymer decolor flocculating agent is according to 3%～5% concentration dilution.The polymerize aluminum chloride weight percent is 90%～96%, and efficient pulping and paper-making advanced treatment agent weight percent is 4%～10%, and organic polymer decolor flocculating agent weight is polymerize aluminum chloride, efficient pulping and paper-making advanced treatment agent mixed 1%～50%.Solution stirring earlier adds polymerize aluminum chloride, efficient pulping and paper-making advanced treatment agent mixed solution the fast pond of mixing with dosing pump after 10 minutes and stirs fast and add the organic polymer decolor flocculating agent after 1 minute and continue to stir 1 minute fast, again by mixing pond adding polyacrylamide slowly, make tiny aggregate under its bridge linking effect, form big throw out, thereby reach the effect that mud-water separation makes purification of water quality by sedimentation or air supporting.
The invention has the beneficial effects as follows: ton water dosage is little, the processing efficiency height, chroma removal rate is stable, can reach or be better than relevant national standard and operation that can be stable in indexs such as adding the COD that makes final discharge water under 50% situation that dose is the polymerize aluminum chloride consumption, colourity, SS, total phosphorus.
Four, embodiment
The present invention is further described below in conjunction with embodiment.
Embodiment one: present embodiment is an example with the second pond water outlet of certain bamboo oar papermaking midcourse wastewater, respectively polymerize aluminum chloride, efficient pulping and paper-making advanced treatment agent in the multi-functional organic sewage treatment agent of economic benefits and social benefits is mixed the back and prepares according to 5% concentration according to 10% concentration preparation, organic polymer decolor flocculating agent.The control dosage is: polymerize aluminum chloride, efficient pulping and paper-making advanced treatment agent mixed solution 100～150mg/L, organic polymer decolor flocculating agent 10～25mg/L.Draining CODcr after treatment is 40～60mg/L, and colourity is 32～40 times, and SS is 12～20mg/L, and total phosphorus is 0.1～0.5mg/L.To reach the relevant discharging of pulp-making waste-water national standard.
The present embodiment processing mode is air supporting, two water PH:7.00～7.40 of settling out.Concrete data such as following table:
Embodiment two: present embodiment is an example with the second pond water outlet of certain reed oar papermaking midcourse wastewater, respectively polymerize aluminum chloride, efficient pulping and paper-making advanced treatment agent in the multi-functional organic sewage treatment agent of economic benefits and social benefits is mixed the back and prepares according to 3% concentration according to 15% concentration preparation, organic polymer decolor flocculating agent.The control dosage is: polymerize aluminum chloride, efficient pulping and paper-making advanced treatment agent mixed solution 150～400mg/L, organic polymer decolor flocculating agent 10～60mg/L.Draining CODcr after treatment is 60～75mg/L, and colourity is 30～45 times.
The present embodiment processing mode is a settling tank, two water PH:6.90～8.10 of settling out.
