This paper summarizes the pollution of domestic animal manure and its processing methods,pointing out the advantage and disadvantage of incineration method,drying expansion method,biogas method composting method and lower animal processing,emphasizing on earthworm processing of domestic animal manure.

Characteristics of cattle manure were studied after vermicomposting for two months, using the raw uncomposted cattle manure without earthworm and natural composting cattle manure as the co.

The variations of biological and chemical parameters of cattle manure during vermicomposting and their correlation coefficients indicated that GI,URE,NH~+_4-N and NO~-_3-N/NH~+_4-N were the priority selected maturity indices for vermicomposted cattle manure,NO~-_3-N and APH common ones,and INV,WSC,WSN and VS unsuitable maturity ones.

Based on the integrated pilot-scale process of anaerobic hydrolysis tank,high-load biofilter and vermibiofilter,the nitrification performance of the vermibiofilter and the influencing factors were investigated.

Sludge reduction performance by earthworm biofilters using quartz sand and ceramsite as media was compared.

To analyze the feasibility of chemical phosphorus removal,the earthworm adaptability and treatment effect in the earthworm biofilter(EBF) were investigated with and without PAC under different temperatures.

Based on histology slice up,this paper presents the microstructure changes of earthworms body wall in earthworm biofilter including the cuticle,epidermis and central muscle,as well as the injury comparison of earthworms body wall in the biofiter with two types of filter mediums(ceramsite and quartz sand).
