Abstract
The invention belongs to the field of water treatment in environmental engineering and in particular relates to a sludge activator. The sludge activator is prepared by the following steps: (1) mincing pancreas of animals, and preparing pancreatic pulp; (2) adding industrial alcohol with the pH of 2.6-2.8 into the pancreatic pulp at the weight ratio of 1:1, stirring at the temperature of 16-18 DEG C, and filtering to prepare a crude extract; (3) regulating the pH of the crude extract to be 8.2-8.3, and preparing an activating solution; and (4) loading the activating solution on bentonite at a weight ratio of the activating solution to the bentonite of 1:1, and drying to prepare the sludge activator. The sludge activity can be effectively improved, the sludge yield is reduced, and the aims of increasing the sewage treatment load and reducing the sludge discharge amount are fulfilled.
Description
Technical field
The invention belongs to the water treatment field in the environmental engineering, particularly a kind of mud activator is used for sludge activation regeneration, is a kind of mud decrement technology.
Background technology
The municipal sewage plant adopts Wastewater Treated by Activated Sludge Process sanitary sewage or industrial sewage.Wastewater Treated by Activated Sludge Process sewage is at set intervals because sludge aging, a part of mud of need draining.Contain organism, heavy metal, virus, pathogenic agent, parasitic ovum of difficult degradation or the like in the mud of draining, therefore need, otherwise will cause secondary pollution through strict subsequent disposal.Along with quickening of urbanization process, sewage load increases year by year, and sludge discharge is also in continuous increase, and sludge yield is generally 3.8～4.0%, and the day quantity discharged of a medium-sized sludge of sewage treatment plant reaches more than the tons up to a hundred.Have mud post-processing technology cost height now, and be difficult to satisfy the environmental protection provisions of laws and regulations of increasingly stringent.Adding the sludge activation agent in aged mud, improve sludge activity, increase sludge age, is to increase the sewage disposal load, reduces a measure of sludge discharge.Existing sludge activation technology has: (1) changes the operational mode of water technology; (2) in reactor, add medicaments such as biological iron, gac, coagulating agent; (3) in returned sluge, adopt the molten cellular lysis of oxidation such as ozone, hydrogen peroxide; (4) in reactor, add methods such as enhancing microbial enzyme activity such as ultrasonic wave, magnetic field and improve sludge activity.Existing method respectively has the fraud profit, the cost height that has, the poor effect that has, the complex process that has, the research trial stage that also is in that has.
On June 18th, 2003, application number is bioremediation and the activator thereof that 03111808.9 innovation and creation disclose a kind of oilfield sewage.This activator is a kind of inorganic nutrient solution, and it contains the inorganic nutrients composition and the selected needed inorganic nutrients composition of bacterial classification that adds that can make original microorganism growth breeding needs in the sewage.On October 10th, 2007, application number is that 200710068549.4 innovation and creation disclose a kind of ecological management method for water pollution, at first with ozone to contaminated water body carry out disinfection, sterilization, then activate beneficial microorganism in the contaminated water body, the organic pollutant in the contaminated water body of degrading with bio-stimulant.Activator in the existing water technology all is to study at the microorganism in the waste water.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of mud activator is provided, play the raising sludge activity, reduce the effect of sludge yield.
The scheme that the present invention solve the technical problem is: a kind of mud activator is characterized in that: got by the following steps preparation:
(1) animal pancreas is rubbed, make the pancreas slurry;
(2) add the industrial spirit of pH=2.6～2.8 by 1: 1 weight ratio in above-mentioned pancreas slurry, stir under 16～18 ℃ of temperature, suction filtration makes crude extract;
(3) crude extract is transferred to pH=8.2～8.3, make activation solution;
(4) by activation solution: wilkinite=weight ratio was stated from activation solution on the wilkinite in 1: 1, dried, and made the mud activator.
As further technical scheme, described animal pancreas is through freezing treatment.
As further technical scheme, described wilkinite is a calcium-base bentonite.
As further technical scheme, the pH of described industrial spirit is regulated by 0.5% oxalic acid solution and obtains.
Beneficial effect of the present invention has:
(1) technology of the present invention is simple, make raw material with animal pancreas, extracting mixtures such as wherein biological enzyme, bio-hormone, bioprotein is carried on carrier and forms, the preparation method only relates to homogenate, extraction, modulation, four steps of load, but concrete parameter must be carried out according to technical scheme is strict, otherwise the mud activator poor effect that makes;
(2) the present invention is with low cost, and main raw material is the pancreas after animal is slaughtered, routine pig pancreas, ox pancreas etc.; Industrial spirit and 0.5% oxalic acid solution price are lower; Calcium-base bentonite is drawn materials conveniently, need not processing; The device simple that the present invention uses is mainly pulverizer, stirrer and reaction vessel.
(3) product of the present invention's preparation can effectively improve sludge activity, reduces sludge yield, and playing increases the sewage disposal load, reduces the purpose of sludge discharge.On the other hand, this product consumption when activated sludge is few, effective.
(4) environment-protection low-consumption of the present invention, animal pancreas is edible not, has realized the changing waste into resources utilization, demonstrates fully the energy-saving and emission-reduction aim.
Embodiment
Embodiment 1
A kind of mud activator is got by the following steps preparation:
(1) select the animal pancreas of freezing mistake for use, chop up rubbing, make the pancreas slurry, what present embodiment adopted is Pancreas Sus domestica;
(2) add the industrial spirit of pH=2.6～2.8 by 1: 1 weight ratio in above-mentioned pancreas slurry, stirred 3 hours under 16～18 ℃ of temperature, suction filtration makes crude extract, and the pH of industrial spirit is regulated by 0.5% oxalic acid solution and obtains;
(3) crude extract is transferred to pH=8.2～8.3 with 10% sodium hydroxide solution, make activation solution, in the present embodiment, the pH of activation solution is 8.2;
(4) by activation solution: wilkinite=weight ratio was stated from activation solution on the calcium-base bentonite in 1: 1, dried, and made the mud activator.
Get the aging mud that an amount of local sewage work drains, the inside adds the mud activator, and the amount that the mud activator adds is aging mud 5 ‰ (weight ratio).In the laboratory by mud: sanitary sewage: industrial sewage=1: 1: 0.5 (weight ratio) is tamed, and adds 5 ‰ glucose in the domestication process and mixes and stir.Tame after 48 hours, compare sludge settling volume (SV with control sample
30) value reduces 6.8%; Sludge volume index (SVI) reduces 18.8%; Mixed solution concentration of suspension (MLSS) reduces 1.98%; Sludge activity increases gradually, measures ATP (Triphosaden) value result and shows, tames that the ATP activity value has increased by 116.6% after 7 days.
Example shows that the mud activator that makes adds in the aging mud, and sludge activity activates obviously, and sludge age is increased, and sludge yield reduces, and is a kind of good mud decrement technology that realizes energy-saving and emission-reduction.
