A kind of biotechnological formulation and by the method for biotechnological formulation lignin-sludge

Technical field

The present invention relates to adopt biotechnology to administer sludge technology field.

Background technology

When wheel of history sailed for 20th century into, entered the age of industrial civilization, the mankind are to naturally destroying and be on the rise, the earth---the ground Founder that these mankind depend on for existence is suffering full spectrum of threats: water pollution, atmospheric pollution, sand and dust fly upward, Cut off, desertification of land ... everybody is in appealing, and everybody is sighing.

China's reform and opening-up is over 30 years, and economy is in a high-speed developing period, and because urban population sharply increases, serious environmental problem is constantly producing one by one.City resident will survive, will live and just must consume, the just inevitable discharged waste of consumption and sewage.And the mud of waste and sewage disposal postprecipitation cannot be administered, World Developed Countries also only has the way of burning and landfill mud at present, has temporarily solved current sludge disposal difficulty, has but left endless potential safety hazard and environmental protection hidden danger.China is fast-developing in recent years, and economic strength strengthens, and city is prosperous flourishing year by year, population agglomeration city.People concentrate life, centralized consumption, concentrate blowdown, the sewage 10kg/d producing per capita, solid waste 1kg/d(is containing domestic refuse).

Municipal sludge is not more perfectly processed disposing technique technology so far, and current taked only have burning method and landfill method exist the problem of energy expenditure and secondary pollution.

Burning sludge method is undesirable, has a large amount of waste gas to produce, and waste gas cost is administered in corresponding increase again; Because it is not inflammable substance for mud, and water content is all in 40% left and right, must add ignition dope combustion-supporting as coal during burning sludge, combustion-supportingly must spend a large amount of energy, produce great amount of carbon dioxide and other obnoxious flavoures simultaneously, it is reported, 1 ton of mud of every burning needs 0.4T-0.6T coal combustion-supporting.The annual approximately 400,000,000 tons of left and right of mud that produce of China, combustion-supporting coal all will be in hundred million tons.

Landfill mud method is also inappropriate, first: because being people, at constantly consumption, mud, just constantly produce, come the mud that landfill is unlimited when just to have the end in our limited soil? secondly: mud is the fluid that there is no plasticity, easily by rainwater, is diluted, again polluted surface water and underground water; Again: mud is poisonous and hazardous, can constantly discharge toxic gas, as, methane, sulfurous gas, hydrogen sulfide etc.

Summary of the invention

Contriver is through research for many years, in environment protection treating technology, look for another way and break through traditional administration idea and technology, adopt biotechnology to solve municipal sludge and only stack a core difficult problem of not administering, also inland river, lake sewage pollution have been solved simultaneously, can make sewage become clear water, smelly water free from extraneous odour, allow polluted lake, river reduces in natural state.The mud puzzlement that sewage work discharges will be expected to be effected a radical cure.

Biotechnology is administered mud, Technology of Sewage, can allow the venomous injurant degraded containing in mud, and heavy metal thing is fully oxidized, stabilizing active gas is volatilization once again not, free from extraneous odour after administering, low power consuming, zero release, mud absolutely recycles, and energy-saving and emission-reduction are performed to a new height.

Biotechnological formulation has unique effect in every field since ancient times.As: coptis bitter, and clearing heat and detoxicating.Ginger is scorching, induces sweat and promotes the production of body fluid.In order fundamentally to solve mud pollution problem, must again found scheme, again look for the new way of administering mud, yet where is new approach again?

Adopt chemical method improvement to pollute unworkable, does the creationary consideration of contriver select plant to solve this problem? according to property analysis, there is the plant of removing toxic substances, sterilization, these characteristics of deodorizing, as mung bean have removing toxic substances heat-clearing function; Chinese honey locust has to fall abolishes smelly function; Sucus Cocois has and falls useless, deodorizing, antibiotic function etc., has respectively unique effect.Contriver extracts, soaks, presses extracting juice to them respectively.In different ratios, be added in mud, then viewing test result.

Found that, the effect of Sucus Cocois is best, but can't reach the regulation effect being entirely satisfactory, and contriver has obtained better effect in conjunction with Sucus Cocois and calcium carbonate and Tai-Ace S 150.
