Description

Rural environmental protection is with concentrated and dual-purpose formula sewage treatment system of dispersion

Technical Field

The invention relates to the technical field of sewage treatment equipment, in particular to a centralized and decentralized dual-purpose sewage treatment system for rural environmental protection.

Background

The agricultural sewage is sewage or liquid substances which are discharged in the processes of crop cultivation, livestock raising, agricultural product processing and the like and affect human health and environmental quality, the rural domestic sewage treatment is to remove and degrade harmful substances and polluted environment components in the domestic sewage for harmless treatment, the rural domestic sewage treatment is mainly to consider and select mature and reliable technologies suitable for rural characteristics and actual sewage treatment, the rural sewage treatment can neutralize the water quality according to actual conditions so as to achieve recycling and environment-friendly degradation discharge, in the rural sewage treatment process, generally, a centralized sewage treatment or a distributed sewage treatment is selected according to the living aggregation conditions of residents in rural areas, if the residents gather in rural life, a treatment tank can be built in a suitable position in the rural areas, and the sewage of the residents is intensively discharged into the treatment tank, and centralized treatment is carried out through treatment equipment, and for some rural areas with dispersed life, such as mountain areas or some remote villages, if centralized sewage treatment is adopted, the construction cost is high, the maintenance is complex, and the distributed sewage treatment is generally adopted.

Referring to the sewage treatment device with the Chinese patent publication No. CN104261521B, the sewage treatment device comprises a power supply device and a reactor, wherein the power supply device is used for providing electric energy for the reactor, the reactor comprises a water inlet pipe, a water outlet pipe, a shell and an inner container arranged in the shell, wherein the shell is provided with a water inlet used for inserting the water inlet pipe and a first water outlet used for inserting the water outlet pipe, and the height of the water inlet on the shell is higher than that of the water outlet on the shell.

Referring to rural sewage treatment equipment with Chinese patent publication No. CN108585355B, sewage firstly enters a sedimentation tank, a filter plate intercepts large-particle silt and other impurities mixed in the sewage, and a coagulant in the sedimentation tank and organic suspended matters in the sewage form flocculation precipitation; the settled sewage enters an adsorption tank through the flow regulation of a regulating tank, and an adsorbent in an adsorption grid adsorbs phosphorus, fluorine, arsenic and the like; and irrigating the wetland plants with the water flowing out of the adsorption tank through a water distribution pipe of the wetland plant tank, removing residual pollutants by the wetland plants, and then discharging to finish rural sewage treatment. The adsorption grid in the adsorption tank is connected with a driving system outside the adsorption tank through a driving part, the driving system can be a slider-crank system, the whole adsorption grid is used as a slider, a crank of the slider rotates under the action of a motor to drive the adsorption grid to reciprocate, so that adsorbent particles in the adsorption grid roll back and forth and are in full contact with sewage, and the adsorption is facilitated; the water inlet at the lower end of the adsorption tank and the water outlet at the upper end of the adsorption tank provide enough reaction time for adsorption, so that the adsorption is more thorough.

A comprehensive analysis of the above referenced patents can yield the following drawbacks:

1) the existing rural sewage treatment equipment can only perform single centralized treatment or distributed treatment, and the application range is narrow, for example, the sewage treatment device in patent CN104261521B and the rural sewage treatment equipment in patent CN108585355B can only perform single adaptive centralized treatment or distributed treatment, and cannot perform centralized and distributed sewage treatment by using an integrated sewage treatment equipment, so that the purpose of freely assembling and switching to use according to actual use conditions cannot be achieved, and the small integrated portable design of the whole sewage treatment system cannot be realized, so that a user can conveniently perform large centralized treatment or distributed treatment, thereby bringing great inconvenience to the use of people.

2) The existing rural sewage treatment equipment is connected and fixed through a single pipeline joint or a single bolt in the process of pipeline connection and installation, the assembly of the pipeline connection mode is complex and insecure, when the pipeline connection is needed, a large amount of assembly time of a user is needed, the labor intensity of the user is increased, and the rapid and convenient assembly of the sewage treatment system cannot be realized.

3) The current rural sewage treatment equipment flocculation sedimentation and sterilization effect are relatively poor, add medicine flocculation treatment through single chemistry, lead to subsiding the effect not good, can not realize adding medicine through the in-process intermittent type formula that leads to water, make flocculation medicament and sewage carry out the intensive mixing, can't reach the purpose that the limit mixes the limit and subsides, the sewage sterilization treatment that has now simultaneously adopts single liquid chlorine of mixing to disinfect, can not realize through carrying out the intensive mixing with liquid chlorine, lead to the sterilization not thorough.
