Description
Technical field
The present invention relates to water treatment, especially relate to a kind of complex coagulation adsorpting formulation and its production and application.
Background technology
Water pollution presents the characteristic of multiple pollutent coexistence, and particularly the discharging with the closely-related organism of mankind's activity, ammonia nitrogen and phosphorus makes contaminated water body generally all show as outstanding organism, the common characteristic of polluting of nitrogen phosphorus.Synchronously remove the organism, the nitrogen and phosphorus pollution that in water, sewage coexist how fast, be a great problem of field of water treatment always.
Problem traditional and various improvement, can solve synchronous degradation of organic substances and nitrogen and phosphorus pollution preferably based on the biological treatment of microorganism metabolism, yet owing to relate to the factor of aspects such as microorganism culturing, structures construction, biological treatment is difficult to realize or satisfy the purpose of removing organism and nitrogen and phosphorus pollution fast.The purpose of organic pollutant and phosphorus can be satisfied fast, be removed synchronously to the coagulating sedimentation effect of traditional inorganic polymer coagulant (IPF such as aluminium system, iron system and ferro-aluminum multipolymer), but it can't reach ammonia nitrogen treatment effect efficiently, also promptly can't remove organism, nitrogen and phosphorus pollutants synchronously.
Domestic have a plurality of patents to relate to that dissimilar coagulating agent is compound or composite to be used for water treatment, all do not relate to whole disclosures of patent of the present invention.In the patent of invention of having authorized, as " a kind of organic polymer-diatomaceous soil composite coagulating agent " (patent No.: mainly be to disclose a kind of the decolouring to use organic polymer-diatomaceous soil composite coagulating agent ZL200710068211.9) at textile dyeing and finishing, paper-making industrial waste water, has the cooperate optimization effect after it is compound, can reach the purpose that improves chroma removal rate, improves the settling of floccus performance, not relate to removing synchronously fast of organism, nitrogen phosphorus; (patent No.: it is composite ZL200710150097.4) mainly to disclose a kind of inorganic polymer coagulant (PAFC), inorganic coagulant (FeCl3) and cationic high-molecular coagulant aids (HCA) as " agent of water treatment compounding coagulation and compounding coagulation method thereof ", solve the problem that colourity is big, residual turbidity is high that adds water behind the molysite separately, do not related to the synchronous removal of nitrogen phosphorus.As " powdery zeolite is removed the method for ammonia nitrogen in the former the water " (patent No.: ZL20041009024.3) mainly disclose the method for the former water ammonia nitrogen of a kind of zeolite treatment, do not related to the efficient removal of organism and phosphorus.The complex coagulation adsorpting formulation is removed organism, nitrogen and phosphorus pollution and Study of Synergistic Effect thereof fast, synchronously both at home and abroad at present and do not see bibliographical information as yet.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of for the defective that overcomes above-mentioned prior art existence can remove complex coagulation adsorpting formulation of organism in the water body, nitrogen phosphorus and suspended substance and its production and application simultaneously and rapidly.
Purpose of the present invention can be achieved through the following technical solutions: a kind of complex coagulation adsorpting formulation is characterized in that this medicament comprises that 4A zeolite molecular sieve 80wt%-98wt% and inorganic polymer aluminium are coagulating agent 2wt%-20wt%.
Described 4A zeolite molecular sieve is a 150-200 purpose Na type molecular sieve.
Described inorganic polymer aluminium is that coagulating agent is polymerize aluminum chloride, polyaluminium sulfate or poly-sulphur aluminum chloride.
A kind of preparation method of complex coagulation adsorpting formulation, it is characterized in that, this method is that the pulverizing of 4A zeolite molecular sieve is levigate, and getting 150-200 order 4A zeolite molecular sieve adding inorganic polymer aluminium is in the coagulating agent, stirs 0.15-0.5h and promptly get product in 300-600 rev/min homogenizer.
A kind of application of complex coagulation adsorpting formulation is characterized in that, according to pending water quality characteristic, adds the complex coagulation adsorpting formulation, and making inorganic polymer aluminium wherein is that the usage quantity of coagulating agent is with Al
3+Count 0.2-1.4mmolL
-1, 4A zeolite molecular sieve usage quantity is 800-2600mgL
-1, stirring 0.5-1h fast at mixing energy GT value 8000-12000 then, 2000-3000 slowly stirs 0.5-1h in the GT value, leaves standstill 0.5-1h afterwards, can be removed the water body of organism, nitrogen phosphorus and suspended substance simultaneously and rapidly.
Compared with prior art, zeolite molecular sieve after the present invention is levigate can obtain bigger specific surface area, zeolite molecular sieve behind the Na ion modification has ammonium ion exchange performance preferably, thereby improve its adsorption to ammonia nitrogen in water, the waste water, because the proportion of zeolite molecular sieve is bigger, in coagulation process, can become the flco core simultaneously to reach effect of flocculant.And zeolite molecular sieve and inorganic polymer flocculant is compound, bring into play the compression double electric layer of polymeric flocculant on the one hand, charge neutralization, build bridge, volume is swept, net is caught effect, precipitate rapidly and remove the bigger pollutent colloid of those particles on the other hand, utilize the bigger serface of zeolite molecular sieve, can be by absorption, pollutents such as ammonia nitrogen are removed in ion-exchange, the high advantage of performance zeolite molecular sieve surfactivity, improve the active of inorganic polymer flocculant and contact with the pollutent colloidal, play the effect of coagulating that helps, thereby speed of response is accelerated, the utilization ratio of flocculation agent improves, and dosage reduces greatly.
The beneficial effect that the present invention has is that the present invention passes through zeolite molecular sieve, compound with inorganic polymer flocculant, performance polymeric flocculant and zeolite molecular sieve are being removed different classes of pollutent, are being improved the cooperate optimization effect of settling of floccus aspect of performance, thereby prepare organic contamination in the water body, nitrogen and phosphorus pollution are had the inorganic polymer coagulant one zeolite molecular sieve compound coagulant about removal simultaneously and rapidly.And, because zeolite molecular sieve is mainly derived from the raw mineral materials that kaolin, diatomite etc. are rich in the silico-aluminate compound, its aboundresources, cheap, therefore coagulating agent of the present invention is recited above to the advantages such as sewage disposal speed is fast, organic and nitrogen and phosphorus pollution is effective, dosage is little except having, and also has quick preparation, advantage that production cost is lower.Technology of the present invention is simple, and the Coagulation and Adsorption medicament after compound is significantly improved to the water body treatment effect that contains organism, nitrogen phosphorus.
