Abstract
The invention relates to a sludge modifying agent which mainly includes following components, by weight, 400-800 of an acid solution with a pH value being 3-4, 300-600 parts of ferrous sulfate and 100-300 parts of hydrogen peroxide. By means of a technical scheme in the invention, dehydration of the sludge can be carried out conveniently and high-efficiently. A dehydration effect that a dehydration ratio can be less than 50% can be achieved. Meanwhile, a cost is low.
Description
Technical field
The present invention relates to a kind of sludge modification agent.
Technical background
Along with China's economy develops the quickening with urbanization rapidly, the scale of municipal sewage treatment constantly expands, and sludge yield is also in quick increase.China's dewatered sludge generation in 2011 approaches 2,200 ten thousand tons, according to < < China sludge treatment, dispose Market Report > > and predicted for 2015 end of the years, China's dewatered sludge annual production will be over 2,600 ten thousand tons.Moisture percentage in sewage sludge is high, can cause mud to stack that floor space is large, transportation cost is high, percolate is difficult, easily produces stench and multiplies mosquitos and flies, produces serious environmental problem.Therefore, improve the dewatering of mud, making reducing sludge volume minimizing is the key of sludge disposal.Current, the water ratio of the mud of municipal sewage plant's discharge is generally up to 80%, in the < < urban wastewater treatment firm mud shale national standard > > implementing at present, also stipulate, moisture percentage in sewage sludge is less than 80%.
But the mud of 80% water ratio is not eliminated the harm of environment, country is decided to be moisture percentage in sewage sludge by standard, and to be less than 80% be to consider China's national conditions in developmental stage at present, and further dehydration will expend a large amount of human and material resources and financial resources.
Summary of the invention
For addressing the above problem, the object of the invention be to provide a kind of convenience, effectively, inexpensively by sludge dewatering, the sludge modification agent that makes the water ratio of dehydrated sludge be less than 50%.
For reaching above-mentioned purpose, provide following technical scheme:
A sludge modification agent, mainly comprises the component of following parts by weight:
PH value is 3～4 acid solution 400～800;
Ferrous sulfate 300～600;
Hydrogen peroxide 100～300.
As a preferred scheme, in formula, also comprise that ratio of weight and number is 1～10 aluminum chloride.
Under the acidic conditions that is 3～4 in pH value, ferrous sulfate reacts with hydrogen peroxide and generates trivalent iron salt, destroys cellularstructure, carries out mud-water separation.As preferred scheme, add aluminum chloride, utilize its throwing out, reduce the requirement of processed to dehydration equipment.
Compared with prior art, adopt technical scheme of the present invention can facilitate, effectively mud be dewatered, can reach dehydration rate is to be less than 50% dehydrating effect; Adopt also very economical of technical scheme of the present invention, cost is lower simultaneously.
