Problems solved by technology

[0002] With the improvement of the rural environment across the country, rural sewage treatment stations have also begun to come into people's sight. However, due to the high dispersion of rural sewage treatment stations, small processing scale, and small amount of residual sludge, the investment in sludge dewatering systems is relatively low. Large, so generally not equipped with sludge dewatering system

Abstract

The invention provides an agent for deeply dehydrating sludge. The agent belongs to a compound microbial reagent and has prominent dehydrating and sterilizing effects. The invention further provides amethod for deeply dehydrating sludge. The method comprises the steps such as agent dehydration, sterilization, concentration, filtration and squeezing as well as solid-liquid separation and is simplein process, convenient to operate, low in treatment cost and remarkable in dehydration effect, and the water content of the dehydrated mud cake is low and reaches 50% or lower, so that the mud cake is convenient to transport and further treat. The invention further provides a device for deeply dehydrating sludge, due to the integrated optical layout of the device, devices relevant to sludge microwave disinfection, agent dissolution, dosing, solid-liquid separation and the like are mounted on a frame, and the frame is placed on a truck, so that the device is low in investment and cost, convenient to move and capable of solving the problem of sewage treatment for rural sewage treatment stations.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a medicament for sludge treatment, a method and a device for deep dehydration of sludge by using the medicament, in particular to a medicament, sewage treatment plant suitable for decentralized rural sewage treatment stations A method and a movable device for deep mud dehydration. Background technique [0002] With the improvement of the rural environment across the country, rural sewage treatment stations have also begun to come into people's sight. However, due to the high dispersion of rural sewage treatment stations, small processing scale, and small amount of residual sludge, the investment in sludge dewatering systems is relatively low. Large, so it is generally not equipped with a sludge dewatering system. At present, the sludge treatment of rural sewage treatment stations is generally transported to large sewage treatment plants for dehydration. In t...
