Description
Technical field
The invention belongs to sewage treatment area, specifically, relate to processing method and the employing thereof of a kind of heavy metal containing sewage
Sewage-treating agent and application.
Background technology
It is one of main Environmental Problems of facing of China that water pollutes.Along with China's industrial expansion, the discharge of industrial wastewater
Amount increases day by day, does not reaches after the industrial wastewater of discharge standard enters water body, can polluted surface water and subsoil water.Water body is once subject to
To polluting, want to recover at short notice to be extremely difficult to.After water body is contaminated, not only can make its water quality do not meet drinking water,
The standard of fishery water, also can make the chemical noxious material in subsoil water and hardness increase, affect the productive life of the people.China
Water resource do not enrich, if occupying runoff computation for each person, be only equivalent to 1/4th of people from world's average, and ground
Table water and the pollution of subsoil water, by making the water resource quantity being available for utilizing day by day reduce further, certainly will affect workers and peasants' fishery raw
Produce, directly or indirectly to people's lives with healthy bring harm.The especially waste water containing heavy metal, to health
Impact is bigger, but heavy metal wastewater thereby is most difficult to process, and the especially heavy metal wastewater thereby of industrial park is most difficult to process, because wherein containing
Chromium, manganese amount are higher, and processing cost is higher.
Retrieval understands, the patent No.: 201410849332.7, title: a kind of sewage-treating agent, and its preparation method is as follows: first
Use FeSO4·7H2O and polrvinyl chloride hollow ball Hybrid Heating, to iron salt hydrolysis, add deionized water wiring solution-forming, more past
Adding highly basic in solution, regulation pH value is to 7～9, and on polrvinyl chloride hollow ball, load forms hydrated ferric oxide, is dried, to obtain final product.
The sewage-treating agent of this invention can preferentially combine the filamentous bacteria in sewage and be wrapped, and forms the most breakable network structure wadding
Body, the current filtration risen in precipitation process, absorption retains the little granule in sewage and free bacteria, so that dirty
Water is limpid.But this invention is unstable, can only process the little granule in sewage and free bacteria, to other pollutant, the heaviest
Metal does not has a detergent power, most crucial go out to dechromise, manganese indifferent.For another example the patent No.: the invention of 201410304516.5
Patent, discloses a kind of sewage-treating agent, including the component of following weight portion: sodium phosphate 20～40 parts, ethylenediamine tetraacetic methene phosphine
Acid 10～15 parts, sodium phosphate 10～20 parts, sodium tripolyphosphate 4～8 parts, silver nitrate 2～4 parts, sodium polyacrylate 4～8
Part.A kind of sewage-treating agent that this invention provides, can effectively remove the pollutant in water, low cost, can reach the standard of discharge.
But after processing sewage with this invention, the water of purification may contain a large amount of phosphorus-containing compounds, enter river, lake and easily cause water body
Eutrophication, and this invention itself is containing heavy metal silver ion, the water body purified may be produced secondary pollution problems.
Summary of the invention
