Abstract
The invention relates to a sewage treatment flocculating agent. The sewage treatment flocculating agent comprises the following components in parts by weight: 10 to 15 parts of chitosan, 2 to 4 parts of alumina, 3 to 5 parts of zeolite and 1 to 3 parts of active carbon. The alumina is aluminum sulfate or aluminium chloride. The sewage treatment flocculating agent is applied in the sewage treatment, the flocculating agent is added in the sewage to be treated to be stirred for 30 to 60 min, and the addition quantity of the flocculating agent is 10mg to 20mg per one liter of waste water. The inorganic flocculating agent is added in the organic flocculating agent according to the proportion, so that the efficacy can be multiplied; moreover, the price is low, the quality is stable, and dosage is little.
Description
Technical field
The invention belongs to technical field of sewage, be specifically related to a kind of sewage treatment flocculating agent and application thereof.
Background technology
The development of industrial and agricultural production, in enriching wealth to mankind's creation, has also caused the pollution problem of harm in various degree, particularly water resources to environment, more and more receive people's concern.Sewage treatment process inevitably will use various flocculation agents, the flocculation agent that sewage disposal is at present used has inorganic coagulant, organic polymer coagulating agent and microbial flocculant, inorganic coagulant is mostly aluminium salt or molysite, mainly with its hydrolysate performance coagulation.Wherein better with the bridge formation absorption property of aluminium chlorohydroxide (PAC), and take the price of ferrous sulfate as minimum.Organic polymer coagulating agent is the polymer that can bring into play the natural or synthetic of throwing out, according to dissociable group characteristic, can be divided into anionic, cationic, amphoteric and non-ionic type.In recent years, the external organic polymer coagulating agent kind adopting is increasing, has the trend that replaces inorganic coagulant, but because of price reasons, uses at home the also rare of organic polymer coagulating agent.The source of microbial flocculant is very extensive, and the production cycle is very short.Compare the flocculation agents such as conventional aluminium salt, molysite, polyacrylamide, algin sodium, microbial flocculant is the highest to the flocculation rate of active sludge, and the flocs unit of generation is easily fallen by filter-cloth filtering.And, the few and good decolorizing effect of their safety non-toxics, non-secondary pollution, applied range, consumption, production cost and treatment technology total expenses are lower than chemical floc.Weak point is that they are easily subject to the interference of toxic substance, and the waste liquid of processing requires not harm the factor of thalli growth.
Summary of the invention
The object of the invention is to provide a kind of sewage treatment flocculating agent and application thereof, adds in proportion inorganic flocculating agent in organic floculant, can improve exponentially usefulness, and price is lower, steady quality, adding less.
To achieve these goals, the technical solution used in the present invention is: a kind of sewage treatment flocculating agent, the mass fraction of component and each component is as follows: 10 ~ 15 parts of chitosans, 2 ~ 4 parts of aluminium salt, 3 ~ 5 parts, zeolite, 1 ~ 3 part of gac.
Aluminium salt is Tai-Ace S 150 or aluminium chlorohydroxide.
The application of described a kind of sewage treatment flocculating agent in sewage disposal adds this flocculation agent in treatment sewage, stirs 30 ~ 60min, and flocculant addition is that every 1L waste water adds 10 ~ 20mg.
Beneficial effect: a kind of sewage treatment flocculating agent provided by the invention and application thereof, in organic floculant, add in proportion inorganic flocculating agent, can improve exponentially usefulness, and price is lower, steady quality, adding less.
