Definitions

  • the invention is based on the use of a low content of dry matter, 10-15 % in the feed material and 2-8 % in the reactor tank, in order to ensure an optimum contact between the substrate and the micro-organisms.
  • the method comprises special measures for pre-treatment of the waste material and the separation of plastic bags from the solid organic household waste.
  • the plant for carrying out the method is provided with a receiving station, cf. Fig. 2, in which sub-atmospheric pressure and bio-filters are used to prevent problems with the smell from the biogas plant.
  • the invention also comprises the use of an ion-exchange apparatus on the basis of a soil mineral for removing ammonia from the residual water.
  • the plant according to the invention is rather simple and is based on experiences from plants used for biological treatment of animal manure together with household and industrial waste in Denmark.
  • the plant is run with a low dry-matter content (3-8%) in the reactor, making the plant cheaper and mechanically less complicated than the plants referred to above.
  • the process is divided into the following steps: a) hydrolysis and acidogenic dehydrogenation, b) acetogenic dehydrogenation, and c) methanogenesis.
  • the va- rious steps are carried out by various bacterial populations.
  • the effectiveness of the process is to a large extent deter- mined by the size and composition of the bacterial biomass.
  • the methane potential of the waste materials depends on the composition of the organic content, lipids especially being of importance with a view to a higher methane yield.
  • the theoretical methane yields for organic materials are 415, 504 and 1014 ml CH 4 /g respectively of organic material for carbohydrates, proteins and lipids respectively.
  • the invention is based upon a biological process, in which solid organic household waste and organic industrial waste are processed together.
  • the organic industrial waste is used for optimizing the composition of the feed material with regard to carbohydrates, proteins and lipids.
  • the or ⁇ ganic industrial waste may possibly also be used for reducing the dry-matter content in the solid organic household waste, and it may also be utilized for preventing problems with am ⁇ monia inhibition of the process.
  • Water resulting from the concentration of the biologically processed material to form a fertilizer product may also be recycled and used for regulating the dry-matter content in the biogas reactor.
  • the invention also relates to starting-up of biogas reactors for processing organic waste materials, such as animal ma ⁇ nure, organic industrial waste and/or solid household waste by the use of granular sludge.
  • organic waste materials such as animal ma ⁇ nure, organic industrial waste and/or solid household waste.
  • the scope of the invention also encompasses the use of granular sludge to increase the yield, e.g. the production of gas from biogas reactors.
  • the starting-up of a biogas reactor is frequently a slow process, and months may pass before the process is stabi ⁇ lized. During this period, the biogas plant will not produce as much biogas as under optimum conditions.
  • biolo- gically processed material from another biogas reactor preferably operating with the same substrate, the requisite starting-up time will be considerably shortened. It has, however, proved possible to shorten the starting-up time even further by using granular sludge from a UASB reactor ("Up-flow Anaerobic Sludge Blanket") for processing waste water.
  • Granular sludge consists of anaerobic micro-organisms, mu ⁇ tually immobilized to form large bacterial lumps with a dia ⁇ meter from 0.5 to several mm. They are used as catalysts in the above-mentioned UASB reactor.
  • the heavy bacterial lumps (the granulae) may be produced in a UASB reactor by con ⁇ trolling the linear flow velocity in the plant and in this manner select the micro-organisms being able to immobilize on each other.
  • New UASB reactors are frequently started-up by using pre-formed granulae of this kind, for which reason these are often sent from one place to another.
  • the invention also relates to monitoring or periodic measure ⁇ ment of the concentration of the volatile fatty acids in plants comprising biological reactors.
  • a special application consists in the control and regulating of biogas reactors processing organic waste and waste water and other types of biomass.
  • the equipment comprises a pre-treatment section, in which the soluble phase is separated from the particles in the material, and this section consists of a ceramic filter with very fine particles.
  • a powerful constant flow through the filter keeps the inside of the ceramic filter clean.
  • the pressure in the filter must be low in order to enable the filtrate to diffuse slowly through the filter material. After this, the filtrate is diluted and acidified.
  • the detector used is a gas chromatograph equipped with a flame ionization detector.
  • the injection into the gas chro ⁇ matograph is carried out by means of an injection valve.
  • the data relating to the concentrations of the individual volatile fatty acids obtained from the gas chromatograph are read into a computer, in which they can be used for controlling and regulating the biogas reactor.
  • Control and regulation of the biological processes in biogas reactors normally occurs by measuring the gas production of the biogas process, at times supplemented with data relating to the composition of the gas. Such measurements will, how ⁇ ever, provide little information about the state of the biological process. Trials have shown that measurements of the concentration of volatile fatty acids in the biogas reactor may be used for judging the state of the process and predict instability in the process. It is believed that measurements of changes in the concentrations of the in- dividual fatty acids in the biogas reactor, combined with measurements of the gas production, will be valuable tools for devising a programme for controlling the feed to biogas reactors with a view of optimizing the production of biogas. At the present time, there exists no equipment for constantly monitoring volatile fatty acids in complex substrates, such as animal manure and other types of waste material.

  • the waste material is transferred from the receiving pit la to the receiving container 2 shown in Fig. 1, this container being equipped with special agitating means, adapted to open the bags containing the household waste.
  • the solid organic household waste is mixed with 25- 50 % biologically processed material from an anaerobic reac ⁇ tor 7 for carrying out a pre-hydrolysis, and with some of the organic industrial waste, possibly also recycled water, in order to change the dry-matter content to 10-15 %.

Abstract

Dans cette méthode anaérobie de traitement de déchets ménagers organiques solides et/ou de déchets industriels organiques, à forte proportion de matière sèche, la nouveauté est qu'avant l'introduction des déchets dans le réacteur à biogaz (7), on leur ajoute des déchets industriels organiques liquides ou semi-liquides dans une quantité telle que le pourcentage de matière organique sèche (solides volatils) atteigne approximativement 15 %. De cette manière, on obtient une proportion de matières sèches optimale du point de vue du processus biologique sans qu'il soit nécessaire d'ajouter, par exemple, de l'eau.
