摘要： PURPOSE:To perform the malodor treatment without generating chloric odor and the secondary pollution in the process of malodorous gas treatment with two stage cleaning liquid by using cleaning liquids with each pH being maintained at a specific range. CONSTITUTION:The malodorous gas 1 such as ammonia and mercaptan is first brought into contact with an alkaline cleaning liquid 13 of pH 10-13 in the first stage gas-liquid contact unit 2. Then, the treated gas 7 is guided into the second stage gas-liquid contact unit 3 where the gas is contacted with the second stage cleaning liquid 10 whose pH is maintained at 6-8 by use of sodium hypochlorite 6 and acid 9. The process provides an efficient removal of the malodorous gas by acid and alkali and causes no chloric odor nor the secondary pollution.

摘要： PURPOSE:To treat the offensive odor gases effectively without generating harmful by-products by a procedure in which ozone is added to the offensive odor gas and then the gas is washed with a chemical liquid. CONSTITUTION:When the multi-component offensive odor gas 1, consisting of acid, neutral, and alkaline components, is treated, the ozone 3 is first added to the gas 1 from an ozonizer 2 to oxidize the offensively odorous components present, and then passed through the first washing tower 4 filled with the acid liquid 5 and then through the second washing tower 9 filled with the alkaline liquid 10 to cause the neutralization reaction of the offensively odorous components to take place. By such a method involving an effective combination of ozone-oxidation method and a chemical liquid-washing method and also the reaction of waste ozone with by-products formed in the washing with a chemical liquid, the offensive odor gases can be effectively treated without generating harmful substances.

摘要： PURPOSE: To enable effective regeneration by a small amount of a regenerating agent, by attaining to optimize the concn. of the regenerating agent in consideration of the reactive characteristics and ion exchange selectivity of a desalting capacity reduced ion exchange substance and the regenerating agent.
CONSTITUTION: In a method for performing regeneration by passing a regenerating liquid through a desalting capacity reduced ion exchange substance, the concn. of the regenerating agent in the regenerating liquid is changed over a part or the entire section of a regenerating liquid passing time with the elapse of the regenerating liquid passing time. For example, in regenerating a Na-type ion exchange resin reduced in desalting capacity with H
2 SO
4 , the concn. of the regenerating agent is made high at the initial stage in the passage of the regenerating agent when the Na
+ -amount of the resin phase is much while the concn. of the regenerating agent is reduced at the terminal period of the passage when the Na
+ -amount of the resin phase is reduced. Because the excessive passage of the regenerating agent is avoided, regeneration at a low level as compared with a conventional method is enabled.

摘要翻译：目的：通过少量再生剂实现有效再生，通过优化浓缩液考虑到脱盐能力降低的离子交换物质和再生剂的反应特性和离子交换选择性的再生剂。构成：在再生液通过脱盐能力降低的离子交换物质进行再生的方法中，在再生液体通过时间过去的再生液通过时间的一部分或全部切换再生液中的再生剂。例如，在用H 2 SO 4还原脱盐能力的Na型离子交换树脂再生时，在树脂相的Na +量多的同时，在再生剂通过的初始阶段使再生剂高。当树脂相的Na +量减少时，在通道的最后期间还原再生剂。因为避免了再生剂的过度通过，所以与常规方法相比能够进行低水平的再生。
