Abstract
The invention discloses a kind of acid domestic sewage treating compound, including 18 25 parts of sodium thiosulfate, polyacrylamide 25 35 parts, sodium aluminate 20 30, sodium hexameta phosphate 10 16, limestone 38, alkaline conditioner 27.This inorganic agent can be greatly lowered COD, the BOD in acid sanitary sewage and total nitrogen index, and makes the solution PH value stabilization after process 79.
Description
Technical field
The present invention relates to technical field of sewage, be specifically related to a kind of acid domestic sewage treating compound.
Background technology
Water is one of indispensable most important physical resources that the mankind depend on for existence and development, along with urbanization process
Swift and violent accelerate and the raising day by day of living standards of the people, the enormous amount of various sanitary sewage generation amounts, growth rate are surprising,
If the most treated nature that is just discharged into of sewage, necessarily environment is produced severe contamination.The most common water treatment agent function list
One, therefore need to add the various medicaments such as flocculant, corrosion inhibiter, oxidant, processing technological flow respectively in water treatment system
Complicated, operating process is loaded down with trivial details, added amount of chemical is big, and produces mutual shadow owing to various medicaments exist obvious Acidity of Aikalinity difference
Ringing, cause drug effect to reduce, specific aim is the strongest.
Summary of the invention
The present invention is for overcoming deficiency of the prior art, it is provided that a kind of acid domestic sewage treating compound, passes through techniques below
Scheme realizes.
A kind of acid domestic sewage treating compound, including sodium thiosulfate 18-25 part, polyacrylamide 25-35 part, sodium aluminate
20-30, sodium hexameta phosphate 10-16, limestone 3-8, alkaline conditioner 2-7.
Further, acid domestic sewage treating compound includes sodium thiosulfate 18-22 part, polyacrylamide 30-35 part, aluminum
Acid sodium 20-25 part, sodium hexameta phosphate 13-16 part, limestone 5-8 part, alkaline conditioner 2-5 part.
Preferably, acid domestic sewage treating compound includes 22 parts of sodium thiosulfate, polyacrylamide 30 parts, sodium aluminate 25
Part, sodium hexameta phosphate 13 parts, limestone 5 parts, alkaline conditioner 5 parts.
The acid domestic sewage treating compound that the present invention provides, its raw material alkaline conditioner is sodium carbonate.
The method have the advantages that
1) raw material is alkalescence, does not produce and influence each other, and saves the usage amount of sewage water treatment agent.
2) COD, BOD5 and the total nitrogen index of processed sewage can effectively be reduced.
3) the solution PH value stabilization after process can be made at 7-9.
Detailed description of the invention:
Limestone pulverizer is crushed to 80-100 mesh, weighs according to composition of raw materials；It is sequentially added into sodium thiosulfate, gathers
Acrylamide, sodium aluminate, sodium hexameta phosphate solid, mixing and stirring；Mixture is dried in 40 DEG C of baking ovens 8-10min,
Stand after taking-up and be cooled to room temperature；Add alkaline conditioner, stir while adding, obtain acid domestic sewage treating compound.

Test effect when the sewage-treating agent of Application Example 1～4 preparation carries out sewage disposal is as follows, each embodiment
Sewage-treating agent input amount is 90mg/L:
| Project | C0D/(mg/L) | BOD/(mg/L) | Total nitrogen/(mg/L) | Solution pH value after process |
| Sewage sample | 3617 | 203 | 152 | |
| Embodiment 1 | 65 | 11 | 27 | 8 |
| Embodiment 2 | 58 | 17 | 20 | 8 |
| Embodiment 3 | 62 | 17 | 24 | 7 |
| Embodiment 4 | 60 | 13 | 23 | 9 |
Although technical scheme is described in detail by above-described embodiment, but technical scheme is also
It is not limited to above example, in the case of without departing from the thought of the present invention and objective, technical scheme is done
Any change falls within claims of the present invention limited range.
