Three new widely distributed and polymorphic species of Amynthas earthworms (Oligochaeta, Clitellata, Megascolecidae) from South China.

Three new earthworm species are described from South China, namely Amynthas rusticanus sp. nov., Amynthas scaberulus sp.

Three new species and one subspecies of the -group from Guangxi Zhuang Autonomous Region, China (Oligochaeta, Megascolecidae).

Three new species and one subspecies of the genus are described from Guangxi Zhuang Autonomous Region, China: The new species are: Qiu & Dong, . and Qiu & Dong, , and Dong & Jiang, , the subspecies is All have four pairs of spermathecal pores in 5/6-8/9, which indicates that they should belong to the -group. Their morphological characteristics are compared to other similar species in the -group from China and other Asian countries, such as Sun & Jiang, 2013, (Chen, 1938), (Kinberg, 1867), Sun & Qiu, 2013, and (Goto & Hatai, 1899).

Four new Amynthas and Metaphire earthworm species from nine provinces in southern China.

Four new species belonging to genera Amyntha and Metaphire were discovered from an extensive area in southern China, covering the provinces Sichuan, Yunnan, Guizhou, Guangdong, Guangxi, Fujian, Hunan, Jiangxi and Anhui. The species are named Amynthas dispersus Sun Qiu, sp. nov.

Three new earthworm species of the tokioensis-group in the genus Amynthas (Oligochaeta: Megascolecidae) from Guangxi Province, China.

Three new species of the genus Amynthas are described from Guangxi Province, China. They are named A. dissimilis sp.

New earthworms of the Amynthas morrisi-group (Oligochaeta, Megascolecidae) from Hainan Island, China.

This paper describes two new species of earthworms belonging to the Amynthas morrisi-group from Hainan Island, China: Amynthas zonarius sp. nov. and Amynthas wuzhimontis sp.

Anaerobic Treatment of Palm Oil Mill Effluent in Pilot-Scale Anaerobic EGSB Reactor.

Large volumes of untreated palm oil mill effluent (POME) pose threat to aquatic environment due to the presence of very high organic content. The present investigation involved two pilot-scale anaerobic expanded granular sludge bed (EGSB) reactors, continuously operated for 1 year to treat POME. Setting HRT at 9.

Zero discharge performance of an industrial pilot-scale plant treating palm oil mill effluent.

Palm oil is one of the most important agroindustries in Malaysia. Huge quantities of palm oil mill effluent (POME) pose a great threat to aqueous environment due to its very high COD. To make full use of discharged wastes, the integrated "zero discharge" pilot-scale industrial plant comprising "pretreatment-anaerobic and aerobic process-membrane separation" was continuously operated for 1 year.

Continuous village sewage treatment by vermifiltration and activated sludge process.

Rural sewage treatment is now paid more and more attention in China. Vermifiltration technology could be one of the practical options under the review of previous studies. It showed good removal rates of contaminants on small to pilot scales for short-term tests.

[Treatment of municipal wastewater with low C/N ratio using an intermittently aerated membrane bioreactor].

A laboratory-scale intermittently aerated membrane bioreactor was applied to treat synthetic household wastewater characterized with low organic matter and high nitrogen concentration. Experimental results showed that at the condition of HRT 12 h, aeration/non-aeration cycle 30 min/60 min and a very long SRT, more than 90% of COD and close 100% ammonia nitrogen could be removed, and the average removal efficiency of TN was more than 80%, but this treatment process seemed to be not available in phosphorus removal. Nitrification was accomplished quickly and completely in the system.
