Description of the Related Art In the processing of fish and shellfish for food, a large amount of perishable wastes such as fish internal organs, shells and other concentrated liquid drainage are accompanied by odor. These are mainly brought into the municipal disposal site as municipal solid waste for disposal, but not only occupy most of the disposal site's capacity but also cause social problems such as foul odors and flies. Expenses are increasing year by year. Also, in thermal power and nuclear power plants, a large amount of cooling water is often collected by seawater collection, and a large amount of barnacles, mussels, oysters, jellyfish, and other plankton are attached to this pipe, and the pipe is blocked as it is. So we are removing them regularly. Even if the discarded products are left unattended, they are easily decomposed and it is difficult to dispose of them.

However, there is a problem that the types of things that can be actually used are limited, and it cannot be the mainstream of effective use.

のである。魚貝類廃棄物の組成例を表1に示す。The fish and shellfish wastes treated in the present invention are mainly residues after collecting raw materials for food processing, wastewater sludge generated therewith, organisms attached to power plants, and the like. It is said that 4 million tons, 1 million tons of sludge, 500,000 tons of shellfish such as oysters, scallops and clams, and 1 million tons of organisms generated at power plants. Of these shells, some are effectively used for crafts and bird food, but most are shells,
It becomes a waste as a whole and is disposed of in landfill as it is or after incineration. These fish and shellfish wastes usually contain unspecified mixture of chemical composition such as internal organs, blood, bone, skin, shell, etc., water content, hardness, and microbial propagation, and they are transported and stored. It requires much quicker processing and is significantly more complicated to handle than other industrial products and raw materials. Table 1 shows an example of the composition of fish and shellfish waste.

It contains aO as a main component and produces slaked lime by reacting with water in wastes of fish and shellfish. Specific examples thereof include quick lime, calcined dolomite, calcined shells, etc., and CaO component is 70% by weight or more. It is desirable to contain.

The particle size may be less than or equal to mm, preferably less than or equal to 1 mm, but if there is crushing equipment at the time of mixing, the particle size may be adapted accordingly.

が多すぎるとコスト高になるので好ましくない。The amount of quicklime mixed depends on the particle size and water content of the fish and shellfish waste, but is generally 50 to 150 parts by weight, preferably 80 to 130 parts by weight based on 100 parts by weight of the fish and shellfish waste.
About parts by weight is used. If the amount of quicklime added is less than this range, the waste is not sufficiently dried and is not suitable as a raw material for cement or steel. If the amount of quicklime added is too large, the cost will increase, which is not preferable.

となり、ホバートミキサー等が好適に用いられる。Various mixers can be used for mixing quicklimes and fish and shellfish wastes, but the higher the mixing efficiency, the better the characteristics of the obtained slaked lime / organic compound mixture (hereinafter referred to as "campun"). However, for example, by setting the mixing time to 3 minutes or more with a mixer capable of stirring at 10 rpm or more, it becomes possible to obtain a suitable camp having a water content of 5% by weight or less, and a Hobart mixer or the like is preferably used.

This exotherm can raise the temperature of the mixture to about 150 ° C., and can obtain a campun having a water content of about 5% or less. Table 2 shows an example of the composition ratio of Campun mixed with quick lime having a CaO content of 94%.

る。On the other hand, the camp remains mainly ammonia (NH 3 + ), and then the so-called rocky odor of amines such as methylamine and trimethylamine. The amount of ammonia generated is as high as 0.1% / g (NH 3 / Kampun) or more at 20 ° C, and its odor is unbearable when exposed to high temperatures such as summer, and deodorizes as necessary. It is desirable to add agents. The deodorant is selected from at least one selected from the group consisting of activated carbon, zeolite, sepiolite, activated clay, van sulphate, iron sulfate and fly ash. Activated carbon, zeolite, and sepiolite surface porous deodorants have a suitable deodorizing effect when the moisture content of Kampung is 3% or less. It becomes saturated and the ammonia adsorption effect cannot continue. Therefore, activated clay, van sulphate, iron sulphate, etc., which exert synergistically the effect of adsorbing and neutralizing ammonia, are preferably used, and when these are added in an amount of 1 to 5 wt. be able to.

The following stable compounds can be obtained, and fungi that cause spoilage are all killed under high alkaline pH, so that the compound can be stored for a long period of time. Minerals in Campun have lime as the main component, and fish and shellfish waste in Campun has a calorific value of about 20000 KJ / kg, so Campun can be suitably used as a raw material for cement or steel. By using it as a raw fuel for industries that perform long-term stable operation, a large amount of waste can be treated without generating secondary waste.
