Abstract
The present invention relates to a special plant-type deodorization agent for sewage treatment. According to the present invention, a plant distillation product, ie., a bamboo vinegar or a wood vinegar, is adopted as a main raw material, appropriate amounts of copper sulfate, an organic acid and a quaternary ammonium salt sterilizing agent are added, and mixing is performed to prepare the deodorization agent, wherein the deodorization agent is provided for removing hydrogen sulfide, ammonia and other foul odors produced during a sewage treatment process.
Description
Technical field:
The present invention relates to a kind of with plant extraction liquid be the deodorant that primary raw material is made, be specifically designed to and remove the foul gas such as ammonia, hydrogen sulfide producing in sewage disposal process, belong to the practical new technology of field of environment protection.
Background technology:
Environmental Protection in China portion " 12 " development plan requires: increase approximately 160,000 kilometers of town sewage pipe networks newly in the whole nation in 2015, newly-increased sewage daily handling ability forty-two million ton, substantially realize all counties and emphasis organic town possesses sewage treatment capacity, sewage treatment facility rate of load condensate is brought up to more than 80%, and treatment rate of domestic sewage reaches 85%.Along with the fast development of Re-search on Urbanization, these sewage treatment plants are more and more nearer apart from resident living workspace, human living standard's raising and the enhancing of Public Environmental Awareness, and the deodorizing problem of sewage treatment plant is just causing increasing concern.For preventing and avoid the impact of sewage treatment plant's stink on surrounding resident life, some developed countries have successively formulated some concrete regulations, for example outside German regulation municipal wastewater treatment plant boundary, within the scope of 300 meters, must not build living facilities, do not reach this requirement, in sewage treatment plant, will take the necessary measure that prevents stink diffusion.Sewage treatment plant that China comes into operation and that build all takes up using Odor con trol as one of requisite link of its treatment process, and the market demand of sewage deodorizing equipment and product presents the gesture of rapid growth.
The stink of sewage treatment plant roughly has fish [the amine CH that smells as of rotten fish

3] and the off-odor of some factory effluent.The conventional foul gas treatment technology of sewage treatment plant mainly contains biofilter, bio-trickling filter, bacteria bed, plant extraction liquid deodorizing, charcoal absorption, energetic ion deodorizing, chemical deodorizing and active oxygen deodorizing etc. at present.
Biofilter, bio-trickling filter and bacteria bed operating cost are lower, and one-time investment is lower, and technology is compared with mature and reliable, apply at present morely, but are subject to freezing impact at cold district.Energetic ion deodorizing the lowest coursing cost, the little and non-secondary pollution of floor space, but one-time investment is larger, applies less.Charcoal absorption initial investment is little, but because charcoal absorption capacity is limited, exceedes certain capacity, just must change active carbon, and active carbon is expensive, cause thus operating cost very high, this method is usually used in the removal of low concentration odorous substance and the last handling process of foul smell.Chemical deodorizing operating cost is relatively high, and equipment investment is very high, and chemical deodorizing method also can produce secondary pollution, and deodorizing effect is general, easily produces secondary pollution, and mainly for the treatment of high-concentration waste gas, this method is not generally advised selecting by sewage treatment plant.Active oxygen deodorizing has advantages of that the life-span is long, but technology is still immature.Plant extraction liquid deodorizing operating cost is moderate, floor space is little, non-secondary pollution and maintenance rate low, be the most economic relatively deodorizing method.
Mainly contain following through patent retrieval discovery with the patent that sewage disposal deodorant or plant type deodorant are associated: " industrial sewage deodorant and preparation method thereof " of patent CN1524803, a kind of deodorant for trade effluent and preparation method thereof, taking industrial chemicals such as ferrous sulfate, aluminum sulfate, polyacrylamides as main." a kind of high-efficiency sewage deodorizing method " of patent CN101850211A adopts biofilter technology to carry out deodorizing.In patent CN011391006, mention and carry out deodorizing with bamboo vinegar, but have no the technical description of processing for the stench of sewage disposal especially.The domestic plant type deodorant patented technology that is applied to sewage disposal that there is no of preliminary identification thus, the present invention can fill up this technological gap.
Summary of the invention:
The present invention, taking plant extraction liquid-bamboo vinegar or pyrolkigneous liquid as primary raw material, adds the deodorant that a small amount of copper sulphate, organic acid, quaternary ammonium salt etc. mix, and its Main Ingredients and Appearance and mass percent are as follows:
1, bamboo vinegar or pyrolkigneous liquid: 50%-98%
2, anhydrous cupric sulfate or cupric sulfate crystals: 0.5%-2%
3, the organic acid such as oxalic acid, citric acid: 1%-5%
3, quaternary ammonium salt bactericidal agent: 0.1-1%
5, water: 0-50%
Pyrolkigneous liquid or bamboo vinegar are that in timber or bamboo wood sintering procedure, pyrolytic distills the gas producing through the cooling liquid obtaining.With acetic acid for leading and containing multiple organic acid, aldehydes, phenols (as phenol, methylphenol, biphenol etc.) material, these organic acid substances can effectively be removed the ammonia in environment, and form organic ammonium salt, at present in a large number for the deodorizing of toilet deodorization and plant.These compositions also have certain removal effect to hydrogen sulfide, organic amine, and can play certain sterilization effect.
For effectively removing the hydrogen sulfide in the foul gas of sewage or sludge creation, the present invention has added copper sulphate and has comprised anhydrous cupric sulfate and cupric sulfate crystals in bamboo (wood) vinegar liquid, itself and hydrogen sulfide (H

For reducing deodorant use cost, sewage treatment plant all needs deodorant to carry out Macrodilution, for guaranteeing deodorizing effect to ammonia after dilution, deodorant of the present invention has added appropriate organic acid and has comprised oxalic acid, citric acid, guarantee that deodorant all can effectively be removed the ammonia in environment in 100 times of situations of dilution.
For killing mould and germ in environment, prevent that harmful microbe from growing, in deodorant, add quaternary ammonium salt bactericidal agent.Comprise mono-quaternaries, bi-quaternary ammonium salt, three quaternary ammonium salts, multi-quaternary ammonium salt, hyperbranched quaternary ammonium salt, the environmental protection of quaternary ammonium salt bactericidal agent, easily biological-degradable, do not endanger natural environment and human health, can rapidly and efficiently kill each bacterioid, germ simultaneously.
