Abstract

The invention discloses a sludge dehydration and conditioning system. The system comprises a conditioning pool, a sludge entering module, a conditioner adding module and a sludge output module; the conditioning pool is connected to the sludge entering module, the conditioner adding module and the sludge output module; the upper portion of the conditioning pool is provided with a sludge inlet and a conditioner adding opening, the lower portion of the conditioning pool is provided with a sludge outlet, the interior of the conditioning pool is provided with a stirrer, and the conditioning pool comprises a closed conditioning pool top; the sludge entering module comprises a flowmeter, and the conditioner adding module comprises an agent storage tank and a weight calculation unit. The invention further discloses a sludge conditioning method. The method comprises the steps of firstly conveying sludge to the conditioning pool, then calculating an average moisture content of the entered sludge, and calculating absolutely dry mud quantity in the conditioning pool, and setting conditioner adding quantity; secondly completing sludge conditioning ; finally conveying the sludge. According to the sludge dehydration and conditioning system and method, the sludge outlet effect is good, meanwhile the agent cannot be wasted, the obtain dehydration sludge through treatment facilitates disposition of backfilling, incineration, land utilization and the like, and equipment in all links operates efficiently and stably, is low in failure rate and high in safety, and greatly saves manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to an automatic control system and method for a sludge dehydration conditioning process. Background technique [0002] With the acceleration of urbanization and increasingly stringent environmental standards, investment in environmental governance has been greatly enhanced. In recent years, a large number of sewage treatment plants have been built in China, and the amount of sludge produced has increased year by year. Sludge is a kind of solid waste with complex composition. If it is not properly treated and disposed of, it will cause great environmental hazards. Since the sludge with high moisture content is difficult to meet the subsequent disposal requirements such as composting, landfill, pyrolysis, incineration, etc., and the reduction is not significant, which increases the transportation cost and difficulty, the document issued by the General Office of the Ministry o...
