Description
Technical field
The invention belongs to technical field of sewage, and in particular to a kind of system of high-efficiency activated biochemical water purification nutritional complexing agent
Preparation Method.
Background technique
Currently, usually containing organic pollutants such as carbohydrate, protein, lignin and greases in sewage, especially
The characteristics of being the sewage containing a large amount of greases, being suspended in the water surface due to grease, sewage surface and air exclusion, frequently result in sewage
A large amount of anaerobic bacteria is bred in treatment process, while fermenting and generating biogas, is influenced sewage treatment process, is caused sewage treating efficiency
It reduces.Therefore grease type suspended matter should be controlled in sewage disposal process, sewage is prevented to be in anaerobic environment.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of preventions and control grease type suspended matter to cover sewage surface,
The high-efficiency activated biochemical water purification nutritional complexing agent of anaerobic bacteria hyperproliferative caused by avoiding, and can effectively improve out sewage treatment and refer to
Mark.
In order to solve the above technical problems, the technical scheme is that a kind of high-efficiency activated biochemical water purification nutrition is compound
The preparation method of agent, the method is as follows: interfacial agent is added in the calcium carbonate soln for being 40~50% to mass concentration, 42~
At 48 DEG C, titanium dioxide three-iron is added, is aged 2.5~3h；Then interfacial agent is added again under heat-retaining condition, stirs evenly, use
Silica is added in sodium hydrate regulator solution pH to 8.9~9.4, is aged 2.5~3h, filtering obtains filter cake, by the filter cake
15~20h is baked at 110~115 DEG C, that is, obtains high-efficiency activated biochemical water purification nutritional complexing agent.
Further, the interfacial agent is sodium tripolyphosphate, and each additive amount of sodium tripolyphosphate is weight of calcium carbonate
0.10~0.25%.
Further, each additive amount of the titanium dioxide three-iron is the 0.15~0.25% of weight of calcium carbonate.
Further, each additive amount of the silica is the 0.02~0.025% of weight of calcium carbonate.
After above-mentioned technical proposal, the present invention uses multilayer coating structure sewage treatment process during the preparation process, and first
When secondary progress titanium dioxide three-iron coats, the titanium dioxide three-iron of addition is the 0.15~0.25% of weight of calcium carbonate, while coating temperature
Degree is 42~48 DEG C, and in the case where three iron content of titanium dioxide is seldom and the lower situation of temperature of plate, titanium dioxide three-iron is in calcium carbonate table
Face forms loose trellis cladding, while there remains a large amount of calcium carbonate in solution, after adding interfacial agent sodium tripolyphosphate,
Calcium carbonate very can easily be covered on the carbonic acid coated through titanium dioxide three-iron under the action of interfacial agent sodium tripolyphosphate
On the loose trellis surface of calcium particle.Silica is added later and carries out second of cladding, and temperature of plate is maintained at 42~48
DEG C, more sparse trellis cladding is formed in calcium carbonate surface.Since there are relatively large gap, seams for sparse trellis cladding
The enough grease type suspended matter molecules of gap enter inside water purification nutritional complexing agent.And due to the unique grid of water purification nutritional complexing agent
Construction, can snarl grease type suspended matter, and the technique of multilayer coating structure can control a large amount of grease inside inorganic agent.
Led to using multilayer coating structure sewage treatment process mainly for the important component grease type suspended matter in all kinds of sewage
It crosses and controls grease type suspended matter using the water purification nutritional complexing agent, largely reduce and covered because grease type is suspended in sewage treatment
In sewage disposal process caused by sewage surface the case where anaerobic bacteria over-reproduction, sewage treating efficiency is improved, thus effectively pre-
Anti- and containment sludge bulking outburst.Treatment effect is stablized, and is suitable for promoting the use of.
The application method of this high-efficiency activated biochemical water purification nutritional complexing agent: it is launched at sewage in the water inlet for the treatment of tank
Agent is managed, as wastewater influent COD > 200mg/L, launches 8~15kg by sewage per ton；When wastewater influent COD concentration be 150~
When 200mg/L, 6~8kg is launched by sewage per ton；When wastewater influent COD concentration is 70~150mg/L, thrown by sewage per ton
Put 4~6kg；When wastewater influent COD concentration is 40~70mg/L, 1~4kg is launched by sewage per ton.
