The utility model is a rapid sewage purification and sterilization device with high processing efficiency, good processing effect, simple structure, convenient manufacture and reliable performance.

Description

A kind of sewage quick purifying disinfection unit

Technical field

The utility model relates to a kind of device to the sewage disinfection.

Background technology

In all kinds of sanitary sewages, industrial sewage, medical sewage, contain various bacteriums, virus, need to remove stink, and reductibility ion such as divalent iron ion, divalent mn ion, negative divalent sulfonium ion and mercaptan, phenolic compound, prussiate, organic sulfide, reduce COD, BOD value, for the dyeing and printing sewage processing of need bleaching and decolour.

It is to adopt chlorine dioxide disinfection liquid as the sterilizing and purifying medicament that a kind of treatment process is arranged at present, adds in sewage and handles.But the dioxide peroxide instability that present chlorine dioxide disinfection liquid producer produces, purity is low, and is low to sewage treating efficiency, weak effect, equipment volume is big, and fault is many, and there are many potential safety hazards in explosive, power consumption height, problem such as labour intensity is big.

The utility model content

Technical problem to be solved in the utility model provides a kind of processing efficiency height, sewage quick purifying disinfection unit that treatment effect is good.

In order to solve the problems of the technologies described above, the utility model generator structure is: the activated reactor upper end is communicated with water sprayer, described activated reactor bottom is communicated with the activation mixing tank, described activation mixing tank is provided with aqueous solution of chlorine dioxide feed-pipe and activator feed-pipe, and described aqueous solution of chlorine dioxide feed-pipe and activator feed-pipe are communicated with aqueous solution of chlorine dioxide storage tank and activator storage tank by volume pump respectively.

Adopt the sewage quick purifying disinfection unit of technique scheme, after each free corresponding inlet volume pump of the stability chlorine dioxide aqueous solution and activator accurately measures, be added in the activation mixing tank and enter into activated reactor again after the mixing, aqueous solution of chlorine dioxide forms chlorine dioxide disinfection liquid by priming reaction under the activator effect, the water sprayer that is communicated with the activated reactor upper end feeds pressure water generation negative pressure chlorine dioxide disinfection liquid is drawn in the water sprayer, is added in the sewage through outlet conduit.By directly in sewer line, adding the CLO after the activation ₂Thimerosal is as long as guarantee mobile sewage and CLO ₂Duration of contact reach 15 minutes, promptly reach sterilisation purpose.

Adopt this treatment unit, the occupation area of equipment that uses is little, need not big civil engineering, equipment is simple and reliable, adopt the A1 level sterilizing agent of world health organisation recommendations to handle waste water, effective except that sewage is carried out disinfection, be subjected to the pH value influence little, do not produce the advantage such as THMS, also have a lot of other effects as: 1, remove iron, manganese; 2, phenols is oxidized to nontoxic quinone; 3, removal is stench; 4, decolouring.

In sum, the utility model is that a kind of processing efficiency height, treatment effect are good and simple in structure, easily manufactured, the sewage quick purifying disinfection unit of dependable performance.

Embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, be provided with water sprayer 7, activated reactor 8 and activation mixing tank 11 in the activation supply device 3, activated reactor 8 upper ends are communicated with water sprayer 7, activated reactor 8 bottoms are communicated with activation mixing tank 11 and are provided with liquid discharge pipe 9, activation mixing tank 11 is provided with aqueous solution of chlorine dioxide feed-pipe 12 and activator feed-pipe 13, aqueous solution of chlorine dioxide feed-pipe 12 and activator feed-pipe 13 are communicated with aqueous solution of chlorine dioxide storage tank 1 and activator storage tank 5 by first volume pump 2, second volume pump 4 respectively, and activation mixing tank 11 is provided with blow-off pipe 10.

Referring to Fig. 1, Fig. 2 and Fig. 3, first volume pump 2 is that the aqueous solution of chlorine dioxide pump of 2-5% is in activation mixing tank 11 with the content in mass in the aqueous solution of chlorine dioxide storage tank 1, second volume pump 4 with the content in mass in the activator storage tank 5 be the hydrochloric acid pump of 4-10% in activation mixing tank 11, be to be mixed with mixed solution at 1: 1 with aqueous solution of chlorine dioxide and hydrochloric acid volume ratio; Along with working on of first volume pump 2, second volume pump 4, aqueous solution of chlorine dioxide and hydrochloric acid mixed solution enter in the activated reactor 8, aqueous solution of chlorine dioxide forms chlorine dioxide disinfection liquid under the hydrochloric acid activation effect, the water sprayer 7 that is communicated with activated reactor 8 upper ends feeds pressure water generation negative pressure chlorine dioxide disinfection liquid is drawn in the water sprayer 7, be added in the sewage lagoon 6 through outlet conduit, make in the sewage lagoon 6 that chlorine dioxide concentration reaches 0.5-5mg/L in the mobile sewage, and reach 15 minutes with duration of contact of dioxide peroxide, promptly reach sterilisation purpose.

After purification work was finished, the liquid in the activated reactor 8 was discharged through the liquid discharge pipe 9 of bottom, and the liquid in the activation mixing tank 11 is discharged through blow-off pipe 10.

Claims

A kind of sewage quick purifying disinfection unit, it is characterized in that: activated reactor (8) upper end is communicated with water sprayer (7), described activated reactor (8) bottom is communicated with activation mixing tank (11), described activation mixing tank (11) is provided with the aqueous solution of chlorine dioxide feed-pipe, and (12 and activator feed-pipe (13), described aqueous solution of chlorine dioxide feed-pipe (12) and activator feed-pipe (13) are communicated with (5) by volume pump with aqueous solution of chlorine dioxide storage tank (1) and activator storage tank respectively.
