Sewage suction truck with residue liquid treatment function

Abstract

The invention discloses a sewage suction truck with a residue liquid treatment function. The sewage suction truck comprises a chassis for transporting fecal sewage, a sewage tank for containing the fecal sewage is carried on the chassis, and the sewage tank communicates with a sewage suction device for pumping the fecal sewage in a septic tank or a sewage pipe network into the sewage tank. The sewage tank further communicates with a flushing and stirring spraying system, the flushing and stirring spraying system is used for flushing and cutting dregs sucked by the sewage suction device and deposited in the sewage tank, and the fecal sewage obtained after the dregs are cut is pumped out of the sewage tank, so that the fecal sewage is sprayed outwards from at least one of the rear portion, the front portion, the two sides and the bottom of the chassis. The sewage suction truck can realize mechanical returning of the fecal sewage to the field, can save a large amount of fecal sewage treatment cost and a large amount of chemical fertilizer cost, improves farmland fertility and agricultural product quality, is beneficial to environmental protection and sustainable development, and has great social significance and economic value.

Description

technical field [0001] The invention relates to the technical field of sewage suction trucks, in particular to a sewage suction truck with the function of treating slag liquid. Background technique [0002] At present, urban manure and sewage are mainly sucked and transported to sewage treatment plants through the sewage pipe network or sewage suction trucks for treatment. With the "toilet revolution", rural manure and sewage are developing towards centralized treatment by sewage treatment plants. Compared with the previous situation, the traditional treatment method of manure and sewage returning to the field is being marginalized. To explore the reasons, there are mainly the following three points: [0003] 1. The treatment mode of the sewage treatment plant is mature, the treatment capacity is large, and it is easy to promote; 2. The traditional waste water returning to the field is mainly done manually without mechanization, which is not suitable for the current social d...
